what is a hydraulic cone crusher? - hongxing machinery

When the cone crusher works, the rotation of the motor is performed by a pulley or coupling, the cone crusher transmission shaft and the crusher cone under the force of an eccentric sleeve to make a swing motion around a fixed point. Therefore, the crushing wall of the crushing cone is sometimes close to and sometimes away from the surface of the mortar wall fixed on the adjusting sleeve, so that the ore is continuously impacted, crushed and bent in the crushing cavity to achieve the ore crushing. The motor drives the eccentric sleeve to rotate through the bevel gear to make the crushing cone rotate, which accomplishes the crushing work when the crushing cone is sometimes near and away from the fixed cone. The connection between the support sleeve and the frame is compressed by a spring so that when an unbreakable object such as a metal block falls into the crusher, the spring will compress and deform to evacuate these objects and achieve insurance to prevent the machine from damaging. If the foreign matter is stuck in the ore discharge, it can be solved by expanding the discharging port and then the cone crusher is automatically reset by the spring to resume normal work.

This hydraulic system controls the movement of 3 basic circuits. One is the action of the fixed cone hydraulic locking hydraulic cylinder, the second is the hydraulic motor that adjusts the gap between the moving and fixed cone. The third is the way of the hydraulic cylinder when the iron is released and cleaned. The lock cylinder is installed between the lock ring and the adjustment ring. It can support the lock ring located on the upper part of the adjustment ring to ensure that the fixed cone is located in the broken position in the adjustment ring when the hydraulic cylinder is pressurized during the crushing process. When the gap between the moving and fixed cones needs to be adjusted, the pressure of the locking hydraulic cylinder is released, and the motor on the adjusting ring starts to start. The gear on the motor engages the driving ring with the adjusting cap to realize the automatic adjustment.

The iron release cylinder is connected to the lower part of the mainframe and is fixed with the adopt to overcome the normal braking force. Abnormal operation or excessive crushing force generated by the foreign object as it passes through the crusher cause the adjustment ring to rise. Once the overload disappears or iron passes through the crusher, the crusher returns to normal. Besides, to clean the crusher, the adjustment ring needs to be removed from the mainframe.

This hydraulic system uses a fixed displacement plunger pump as the power source, that is to say, it converts the mechanical energy supplied by the prime mover into the pressure energy of the working medium (hydraulic oil). During this period, each hydraulic valve controls and regulates the pressure, flow, and direction, to ensure that the execution part (each hydraulic cylinder and motor) to complete the predetermined law of movement. The maximum pressure of the electromagnetic relief valve adjustment system in this circuit is 20MPa. The locking circuit is controlled by accumulator pressure and zero leakage solenoid valve. Because the lock cylinder is always in a pressure-maintaining state during the working process, the use of an accumulator to maintain pressure can prevent the plunger pump from starting and stopping frequently. The locking cylinder is a plunger cylinder so that the zero-leakage solenoid valve is reset by the weight of the support part after the pressure is released.

Adjust the motor circuit by using a shuttle valve to control the motor running and stopping. Due to the working nature of the host, the motor needs to have a brake function. Therefore, the shuttle valve is used to control the brake of the motor. Thus, the motor can realize the function of oil-braking and oil-cut braking. Accumulators are used to absorbing shocks in the iron release and cleaning circuits. Due to abnormal operation or excessive crushing force generated by the crusher when the main machine is working, the adjustment ring rises upward. When the adjustment ring rises, the hydraulic oil in the upper cavity of the hydraulic cylinder will be squeezed into the accumulator, then the nitrogen in the accumulator is compressed. After that, the compressed nitrogen forces the hydraulic oil to return to the hydraulic cylinder, and the piston rod of the hydraulic cylinder is retracted, and the adjustment ring is returned to the original position. This circuit uses an accumulator to absorb shocks easily, easily and reliably.

The most common types of hydraulic cone crushers are single-cylinder cone crusher, multi-cylinder cone crusher, and fully hydraulic crusher.SCseries single-cylinder hydraulic cone crusher is developed with advanced crushing technology, integrating mechanical, hydraulic, electrical, intelligent control, etc.Thesingle-cylinder hydraulic cone crusherhas a new crusher structure, optimized laminated crushing cavity type, and a fully intelligent automation control system. In general, itcan be widely used in medium crushing, fine crushing, and ultra-fine crushing operations.

Multi-cylinder hydraulic cone crusher is suitable for crushing various ores and rocks with medium or higher hardness, such as limestone, iron ore, cobblestone, non-ferrous metal oreand so on.Its high speed, high crushing capacity, and unique patented design make the crushed finished producta high-quality cube shape, and the easy maintenance feature can ensure its high stability operation.

The full-hydraulic cone crusher is a new cone crusher that combines advanced multi-cylinder hydraulic cone crusher and PSG cone crusher. This machineadopts advanced design concepts and is optimized and designed. The fine-grained content in the crushed product is higher, and the content of the granules smaller than the closed-side discharge can reach 80%, which can significantly improve the processing capacity of subsequent processes and reduce comprehensive energy consumption.

The successful combination of high-performance crushing cavity type and high crushing frequency has greatly improved the processing capacity of the machine. Due to the principle of lamination crushing, the crushed products are mostly cubic structures, which greatly reduces needle-shaped materials.

symons cone crusher

symons cone crusher

For finer crushing or reduction a Symonscone crusher the norm. Symons are commonly used for secondary, tertiary or quaternary crushing. They do this by a different chamber design which is flatter and by operating at about twice the rotational speed of a primary type gyratory crusher.

One of the first cone crushers had a direct drive vertical motor mounted above the spider with the drive shaft passing through the hollow bored main shaft. With relatively high speeds of 480 to 580 rpm and small eccentric throw, the machine produced a uniform produce with minimum fines.There are numerous Symonscone crusher manufacturers of modern crushers each promoting some unique aspect.

The Allis Chalmers Hydrocone selling point is its adjustability and tramp protection through a hydraulic support system for the headcentre. By merely adjusting the oil reservoir below the head centre the crusher setting can be changed while in full operation. Tramp metal causes a surge of pressure in this hydraulic system which is absorbed through relief valves and gas-bladder-filled accumulator bottles which allow the headcentre to momentarily drop and return to its normal operating position when the tramp has fallen through.

The Symons or Rexnord spring cone crusher is adjusted by spinning the bowl up or down manually or through hydraulic rams. A series of powerful springs give the necessary tramp protection. Several other manufacturers produce similar types and sizes of crushers but all follow the basic types described.

When the Symons brothers Invented the cone crusher, they employed the principle wherein the length of the crushing stroke was related to the free fall of material by gravity. This permitted the material being crushed to fall vertically in the crushing chamber; and in effect, caused the particles to be crushed in a series of steps or stages as the particles got smaller due to the crushing action. This also helps to reduce the rate of wear of the liners since the sliding motion of the particles is minimized.

Recognizing that the Symons principle of crushing is the most efficient means of ore and aggregate reduction in hard rock applications, the engineers used this same principle in the design on the hydrocone.

Versatility in the form of having the ability to perform in a wide range of applications without the need for a change in major assemblies was another objective in the design. Ease of maintenance and remote setting capability also were part of the design parameters the market requires.

There is no startling revelation to the fact that the mining industry as a whole is generally moving toward the use of larger equipment to process ores in quantities far greater than what was even considered a decade ago. Trucks and shovels have led the way in extra large machines and many other manufacturers have followed suit in the development of so-called supers in their line of equipment.

In order to keep pace with the industry, crusher manufacturers have also enlarged the size of their equipment. There is now on the market, a Gyratory crusher capable of accepting a 72 diameter piece of ore. Primary jaw crushers have also increased in size. It is inevitable, therefore, that larger secondary cone crushers would also be required to complement the other equipment used to process these large quantities of ore. This super-size secondary cone crusher is the SYMONS 10 Ft. Cone Crusher.

Until 1973, the largest cone crusher built was the 7 Ft. Extra Heavy Duty crusher, which is currently used in the majority of the mining operations throughout the world. The 10 Ft. crusher, when compared to the 7 Ft. Extra Heavy Duty Crusher, is approximately 1 times larger in physical dimensions; three times heavier; will accept a maximum feed size which is approximately twice as large; and will crush at approximately 2 times the rate of the 7 Ft. machine at identical closed side settings. It will be the largest cone crusher built in the world.

The conclusions of this investigation were all positive the crusher could be built and at a cost that would be in line with its size and capacity and also with other size crushers. After that preliminary study, the project became dormant for several years.

The project was reactivated and this time general assembly drawings were made which incorporated many improvements in the crusher such as pneumatic cylinders in place of the conventional, springs for tramp iron release, a two-piece main frame a dynamically balanced design of the internal moving parts of the crusher, and an automatic clearing and adjusting mechanism for the crusher. At this stage of development we felt we were ready to build a 10 Ft. crusher for any mine that was willing to try one. Unfortunately, the conservative posture of the mining industry did not exactly coincide with our sales plans. This, added to the popularity of the autogenous mill concept at the time, led to another lull in the 10 Ft. development program.

The project was reactivated again in 1970, this time primarily at the request of one of the large Minnesota Iron Range mining companies. We then undertook a comprehensive market research study to determine if there was a need for this size crusher by the mining industry in general, rather than just the iron ore industry. We talked not only to the iron ore people but to the copper people and persons connected with the other metallic ores as well. The acceptability of this large crusher was also discussed with the aggregate industry. After interviews with many of the major mining companies, the decision was made to complete the entire engineering phase of the development program and to actively solicit a customer for this new crusher. We spent approximately $85,000 on engineering work and tests on the gamble that we could find a customer. I speak of a gamble because during our market research study we continually were told my company would be very interested in buying a 10 Ft. crusher, but only after we have seen one in operation.

The actual building and test of the first prototype unit without a firm commitment for a sale was an economic impossibility. We were now at the point where we needed to sell at least one unit in order to prove not only the mechanical reliability of the machine, but the economic justification for its purchase as well. Needless to say, when the order for two SYMONS 10 Ft. cone crushers was received, we felt we were now on the way toward completion of the development program.

Perhaps at this point it might be apropos to examine the crusher itself. It will stand 15-6 above its foundation, the overall height will be 19-4-. At its greatest diameter, in the area of the adjustment ring, it will be approximately 17-6. It will weigh approximately 550,000 lbs. Under normal crushing conditions, the crusher will be connected to a 700 HP motor. A 50 ton. overhead crane is required to perform routine maintenance on this crusher.

The main shaft assembly will weigh approximately 92,000 lbs. and the bowl assembly approximately 95,000 lbs. The mantle and bowl liner, cast from manganese steel, will weigh approximately 13,000 lbs. and 25,000 lbs. respectively.

The throughput capacity of the Standard will be approximately 1300 TPH at a 1 closed side setting and 3000 TPH at a 2- closed side setting. The throughput capacity of the SHORT HEAD will be approximately 800 TPH at closed side setting and 1450 TPH at a 9/16 closed side setting.

Persons familiar with the design of a conventional 7 Ft. SYMONS cone crusher will recognize that the design of the 10 Ft. is quite similar to it. As a matter of fact, we like to say that the design of the 10 Ft. is evolutionary rather than revolutionary, because all the reliable features of the SYMONS cone crusher were retained and the only changes that were made were those that added to the convenience of the operator, such as automatic clearing and automatic adjustment. From a mechanical point of view the stresses generated due to crushing loads are less in the 10 Ft. crusher than in the existing 7 Ft. Extra Heavy Duty cone.

One of our senior engineers who has long since retired told me that he had the occasion many years ago to make a presentation of a newly designed crusher to a prospective customer. He carefully prepared a rather detailed description of the crusher which included all the features that his new machine had when compared to the customers existing machine. The presentation itself took about one hour and after that period the customer leaned back in his chair and said, Thats all well and good, but will it crush rock? In effect, the customer was; saying that all the features in the world were of no use to him if the crusher did not perform its basic function to crush rock and ultimately make profits for the owner. Using todays financial terminology he was asking the engineer to economically cost justify the purchase of the crusher.

The working day of the contemporary manager or project engineer evolves around making decisions to economically justify a piece of equipment or a new operation. In our development program of the 10 Ft. cone crusher, we felt that the economic justification, from the customers point of view, was just as important to develop as the engineering aspects of the program. So we developed a three-part program to examine the economics of installing a 10 Ft. crusher. First we talked in wide generalities concerning the use of a 10 Ft. crusher. Secondly, we discussed the ramifications of using a 10 Ft. crusher versus 7 Ft. crushers in a completely new plant being considered for the future. Thirdly, we examined how a 10 Ft. crusher could be used to its best advantage in a plant that is being expanded.

The first consideration was the economic generalities of installing the crusher, or more specifically, what questions regarding the installation are pertinent to every crushing plant. Usually, the initial comparison which is made between a 7 Ft. crusher and a 10 Ft. crusher is that of price versus capacity. Theoretically, the capacity of a 10 Ft. crusher is 2 times that of a 7 Ft. while the selling price is approximately 3 times that of the 7 Ft. On that basis alone, it would appear that the 10 Ft. could not be justified. However, this is an incomplete picture. Recent cost estimates show that considerable savings are realized when the entire physical plant structure is considered. Because fewer machines are required to crush an equivalent amount of ore, the size of the buildings can be reduced, thereby decreasing the capital investment of buildings and allied equipment used as auxiliaries for the crusher.

Total manpower requirements to operate and maintain the plant is another of the generalities which were considered. Fewer crushers normally require less personnel to operate and perform maintenance, Manpower requirements obviously play a large part in the profitability of a plant. Therefore, it follows that using a 10 Ft. in place of multiple 7 Ft. units should be more profitable from the standpoint of manpower. We should, however, clarify one point regarding normal maintenance of the 10 Ft. crusher which is commonly misunderstood; namely, the periodic changeout of manganese liners in the crusher. The normal time period between manganese changes would not be significantly different between the 7 Ft. and a 10 Ft. because the wear rate, that is, the pounds of liner worn away per ton of ore crushed, will remain the same. Consequently, if a set of liners in a 7 Ft. crusher, lasted six weeks, a 10 Ft. crusher in the same operation would also last approximately six weeks. However, since the total amount of ore crushed will be greater, the maintenance costs per liner changeout will be less on the 10 Ft. crusher.

Another point for consideration is that the 10 Ft., cone crusher is a secondary crusher and normally would be fed with the product of a gyratory crusher. Since the 10 Ft. can accept a larger feed than a 7 Ft. crusher, it is possible to increase the open side setting of a gyratory crusher, thereby, allowing a greater volume of feed to pass through the crusher. Because of this, it is conceivable that a smaller primary crusher could be used in order to obtain a given quantity of ore.

A good salesman could expound on a multitude of ideas for using 10 Ft. crushers in place of 7 Ft. crushers in a new plant, but in the final analysis, the deciding factor as to whether or not the 10 Ft. crushers should be used will be the anticipated over-all plant capacity. Several studies have indicated that as a general rule of thumb the break even point for using 10 Ft. crushers in place of 7 Ft. crushers is a plant which will have an overall ore treatment capacity of approximately 40,000 TPD or approximately 8,000,000 TPY. Anything less than that figure should indicate the use of conventional 7 Ft. crushers. Obviously a small four stage crushing plant in which the third stage crusher was a 7 Ft. Standard and the fourth stage consisted of two 7 Ft. SHORT HEAD cone crushers, would not improve economically by the use of one 10 Ft. Standard cone crusher and one 10 Ft. SHORT HEAD cone crusher in place of the 7 Ft. crushers.

A study was made which considered a plant to be built using three different approaches of a conventional crushing-grinding operation. The plant which was being considered would be crushing taconite similar to that found in the Iron Range. The end product of the crushing was 5/8 rod mill feed and in this example the plant capacity was to be approximately 13.5 million TPY of ore processed to eventually produce approximately 4 million TPY of iron ore pellets. The study arbitrarily chose a four-year period of operation so that operating costs would be included and also because a four-year period is the usual comparison basis for calculating return on investment. In this example the primary crusher as well as the fine crushing plant would be operated fourteen shifts per week.

In our economic analysis of the 10 Ft. crusher development program, we also studied how this crusher could be used to best advantage when planning expansion of an existing plant. Before delving into the actual dollars and cents of several variations of expansion plans, several preliminary questions must be answered in the affirmative:

Since each plant is unique, the relative merits of the 10 Ft. crusher must be examined on an individual plant basis. Again, as a general rule of thumb, it has been found that the most benefit can be achieved in those plants which presently contain a four-stage crushing plant in which the first two stages of crushing are gyratory crushers. Studies have shown that converting the second stage gyratory crusher to a 10 Ft. Standard crusher shows most potential because the major auxiliaries required for the crusher, such as crane, conveyors, etc., are already large enough to accommodate the increased capacity of the 10 Ft.

As one possible solution, we suggested that the two 30 x 70 secondary gyratory crushers be replaced by two 10 Ft. Standard cones. These crushers could then send approximately 3600 TPH of minus 3 material to the fine crushing plant. The two existing 7 Ft. Standard crushers could be converted easily to SHORT HEAD crushers and two new 7 Ft. SHORT HEAD crushers added to the existing vacant foundations.

In Summary, we feel that the Symons cone crusher has a very definite place in the future of the mining industry and we intend to move steadily ahead with its progress. However, we have learned a few lessons along the way.

Initially, the development of these super size machines is an extremely expensive proposition. We know that if our company alone, attempted to completely design, manufacture, erect, and test a machine in this size range, it would severely tax our financial resources.

We found that super size equipment also presents some problems for our manufacturing facilities. The manufacture of one of these units puts a large dent into the production schedule of many of the smaller conventional units. In our enthusiasm to build a bigger newer machine, we continually remind ourselves that the smaller conventional units are still our bread and butter units.

On the positive side, we found that our reputation as a crusher manufacturer was enhanced because of what our customers refer to as progressive thinking. We listened to the suggestions of the mining industry in attempting to give them what they wanted.

Perhaps you will allow me to close with a bit of philosophizing from a manufacturers point of view. The 10 Ft. crusher is here ready to go into operation. Where do we go from here? A 15 Ft. cone crusher? A 20 Ft. cone crusher? Who knows? We do know that we have reached the financial limit of a development program on a machine of this size. We also know that as the size of a machine grows larger, the developmental and manufacturing risks grow larger along with it and any allowable margin for error must be minimized. We, like you, are in business to make a profit. Since larger crushers usually mean a fewer number of crushers, we must examine the profit picture from aspects of the sale. I think I speak for other manufacturers as well when I say that bigness in machines reflects bigness in development costs as well. If the mining industry wants still larger equipment in the future, the industry should prepare itself to contribute to the development program of those machines.

TheHydraulic Cone Crusheruses hydraulic tramp release cylinders and accumulators to hold the adjustment ring against the main frame seat. There is only one angular surface between the main frame and the adjustment ring which also has a radial contact point in the lowermost area. When a piece of tramp goes through the crusher, the oil is forced into the accumulators allowing the adjustment ring to raise and pass the tramp.

The tramp release cylinders are secured to the adjustment ring and the lower portion of the main frame through clevises. This allows the crushing forces to be transferred directly from the frame arm locations to the adjustment ring. This relieves the main frame shell and upper flange from carrying heavy loads.

The Hydraulic Cone Crusher is equipped with hydraulic clearing. The tramp release cylinders which hold the adjustment ring in place are double acting cylinders. These cylinders can be pressurized in the opposite direction, after the clamping pressure has been released, to raise the adjustment ring and bowl assembly for clearing; only the weight of the adjustment ring, clamp ring, and bowl assembly, plus any residual material in the bowl hopper raises.

how to choose cone crusher? the difference and advantages and disadvantages of single-cylinder and multi-cylinder hydraulic cone crusher?_zhengzhou vanguard machinery technology co., ltd

Cone crusher is currently one of the widely used mining machinery and equipment. With the development of the market, there are many types of products at home and abroad, and the performance of each type of crusher is different. At present, spring cone crusher and hydraulic cone crusher are more commonly used, and hydraulic cone crusher is divided into single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher. This article mainly compares the difference and advantages and disadvantages of single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher. And hope to bring some help to your selection.

In addition to the structural differences of main unit, spare parts and wearing parts between the single-cylinder hydraulic cone crusher and the multi-cylinder hydraulic cone crusher. The main differences are as follows:

During normal operation, the oil pump is used to fill or drain the oil cylinder of the main shaft to move the main shaft up or down (the main shaft floats up and down), and adjust the size of the discharge port. This adjustment method may cause the discharge port to be more difficult to lock when crushing hard ore.

The adjustment cap is adjusted by a hydraulic pusher or a hydraulic motor to drive the adjustment ring to rotate in the support sleeve (the fixed cone screw rotates and moves up and down) to achieve the adjustment effect. The advantage of this adjustment method is that the discharge port is easy to lock.

When iron pass-through, hydraulic oil is injected into the accumulator, and the main shaft falls; after iron pass-through, the accumulator presses the oil back, and the crusher operates normally. A hydraulic pump is also used when cleaning the cavity.

When non-crushable material passes through the crushing cavity or the machine is overloaded for some reason, the hydraulic safety system realizes insurance, and the discharge port is enlarged, and the non-crushable material is discharged from the crushing cavity. If non-crushable material is stuck in the discharge port, the cavity cleaning system can be used to further enlarge the discharge port and discharge the non-crushable material out of the crushing cavity. Under the action of the hydraulic system, the discharge port is automatically reset and the machine resumes normal operation.

Two oil inlets are filled with oil, one is from the lower end of the main shaft to lubricate spherical bearings, spherical bushes, frame bushings, main shaft bushings, and then large and small bevel gears; the other way enters from the end of the drive shaft to lubricate the drive shaft bushings, and finally The two oils are discharged from the same oil outlet.

After entering the machine from the oil hole at the lower part of the machine and reaching the middle of the main shaft, it is divided into three branches: the inner and outer surface of the eccentric sleeve, the oil hole in the middle of the main shaft reaches the ball bearing, and passes through the channel to lubricate the small and small bevel gears; The oil enters the hole to lubricate the transmission bearing, and the oil returns through the oil return hole at the lower part of the pinion gear and the oil return hole on the dust cover.

The single-cylinder hydraulic cone crusher is similar to the spring cone crusher . Therefore, the main shaft and the movable cone are supported by the base, and the eccentric sleeve drives the main shaft to provide crushing force.

The main shaft of the multi-cylinder hydraulic cone crusher is thick and short, and its diameter can be designed to be large. It stands directly on the frame (not in the eccentric sleeve) and provides high bearing capacity. The eccentric sleeve directly drives the moving cone to provide crushing force.

When crushing soft ore and weathered ore, the single-cylinder hydraulic cone crusher has the advantage of large throughput, and when crushing medium-hard and high-hard ore, the performance of multi-cylinder hydraulic cone crusher is more outstanding.

For the fine crushing of medium-hard and above ores, the multi-cylinder cone crusher can produce more qualified products under the same specifications. Generally speaking, the higher the rock hardness, the greater the difference between single-cylinder and multi-cylinder operations.

The single-cylinder cone crusher has simple structure and reliable performance: a hydraulic cylinder, simple and compact structure, low failure rate, low production cost (the simpler the mechanical system structure, the lower the failure rate, the higher the reliability, and the more stable the operation).

The top or side of the multi-cylinder cone crusher can be disassembled and assembled, so the maintenance is quick and convenient. All parts can be disassembled and maintained from the top or side. Replacement is more convenient.

Advantage 1:Compare to the multi-cylinder hydraulic cone crusher, the airframe structure of a single-cylinder hydraulic cone crusher is simpler with fewer parts, from the appearance, more attractive design.

Advantage 3:In the actual operation process, the equipment is easy to install and maintain. And from a technical perspective, the single-cylinder hydraulic cone crusher has made technical improvements to the sliding bearings. The improved equipment can adapt to higher speeds, increase the swing speed of the spindle, and make the specifications of the finished materials more in line with the requirements, and the capacity is also higher. Disadvantages: The biggest disadvantage of single-cylinder hydraulic cone crusher is that it has only one oil cylinder, so the crushing force is smaller than that of multi-cylinders. If you crush some hard stones, it is recommended to choose multi-cylinders.

Advantage 1: The multi-cylinder hydraulic cone crusher has a reasonable structure by partially upgrading and improving from the traditional spring cone crusher. The equipment applies multi-cylinder hydraulic technology to make the crusher with a large crushing ratio. Under the condition of ensuring that the capacity reaches the standard, the energy consumption is also controlled. And it is suitable for many stones, especially suitable for crushing stones with a hardness of not more than 300Mpa.

Advantage 2: Multi-cylinder hydraulic has a special crushing cavity design, and the capacity is greatly improved. The semi-automatic hydraulic adjustment of the discharge opening can effectively control the size of the stone material, and the finished material can reach the specifications required by oneself. So it is more economical and practical to use.

Advantage 3: When a good crusher manufacturer manufactures a multi-cylinder hydraulic cone crusher , it will use a high-strength monolithic cast casing, and it is protected by iron, which is safe and reliable. The performance of the equipment is very stable regardless of how hard the stone material is crushed. And the service life is long.

Disadvantages: The multi-cylinder hydraulic cone crusher uses a labyrinth-type sealing structure, which can prevent dust, but the bad labyrinth-type sealing property will also have dust ingress by a manufacturer with inexperience or poor manufacturing technology. If the stone with more dust is crushed, it may be difficult to adjust the discharge outlet. So it is a key point to choose a manufacturer with a good brand reputation.
