As the key material for infrastructure, natural stones are generally large and not suitable for construction, so we need suitable equipment for crushing the stones into small sizes or changing their shape.
At present, the equipment used in the stone crusher plant is divided into fixed stone crusher machines and mobile or portable stone crusher machines. Based on this, two types of crushers are developed, namely semi-mobile or semi-portable stone crusher machines and semi-fixed stone crusher machines.
Mobile (portable) stone crusher machines, also called mobile or portable crushing plant, are generally composed of crushers (jaw crusher machine, impact rock crusher, hammer crusher, cone crusher machine, roll crusher machine), screening machine, feeder, conveyor, control system, etc.
Combining primary crushing, secondary crushing and sand making into one, the mobile crushing plant adopts self-driving method so that the components can be fixed on a whole frame. It moves by crawler or tire type track to crush the materials in a mobile manner.
The feeder feeds the stone into the crushing chamber. After being crushed and sieved, the qualified finished products are transported to the finished product warehouse, and unqualified can be crushed again.
Because it is a Trinity equipment, and the continuous transportation equipment connected is belt conveyors, the crawler type mobile crushers are suitable for large-scale open mining and large-scale and continuous mining processes.
The semi-mobile stone crusher machines are also called semi-portable stone crusher machines. It is to place the body in the appropriate working level in the open pit. With the advancement of the working steps, it can be pulled and transferred by a crawler truck or other traction equipment with its whole set configurable machines.
The most typical feature of semi-mobile crushing stations is that they are connected to the concrete-free foundation. Their service life ranges from a few months to several years, and the migration time usually is less than 48 hours.
The semi-mobile stone crusher is usually placed on the working slope, and the transport distance should be less than 3 km. When the mining steps extend to the outside of the reasonable transport distance and climbing height of the vehicle, the next shift should be performed.
From the perspective of the foundation, its crushing frame has a strong connection with the ground (the bedrock can be connected by anchor piles, and concrete foundation can be used in the loose area).
From the perspective of the position of the layout, it is generally fixed on the working slope to minimize the frequency of movement and improve the service life, especially for rock crushing and transportation.
When the semi-fixed stone crusher is moved, only the body of the device that is bolted to the foundation can be disassembled and moved for reuse, and the foundation buried below the surface is discarded.
The fixed crusher machines are usually arranged outside the boundary of the stope, or placed in the interior of the stope and arranged in conjunction with the chute, which is not affected by the advancement and deepening of the stope. It has a permanently fixed foundation connection with the ground.
The feeding method is diversified. The automobile can directly discharge the materials, or the buffer silo can be set for feeding through the ore-mining device. The fixed crusher is generally in the crushing workshop, and has the same life as the mine.

Stone crusher plant machine plays an important role in the stone crushing industry. The crushed stones can be used as raw materials for various construction activities like construction of roads, highway, buildings and bridges etc. As a famous stone crushing machine manufacturer, SBM can provide clients the high quality machine and low stone crusher plant cost.
Stone crusher is widely used in mining, metallurgical, construction, chemistry, petrochemicals, transportation, energy, building materials industry, suitable for crushing high hard, mid hard and soft rocks and ores such as iron ore, limestone, slag, marble, quartz, granite, cement, clinker and so on.
The whole stone crusher plant plays vital role in the mining process. Jaw crusher, cone crusher, impact crusher, VSI crusher and hammer crusher is the main equipment in stone crusher plant. The vibrating feeder takes the raw materials into jaw crusher for the first crushing process. The big block materials will be crushed into small size. With cone crusher or impact crusher, the materials will be crushed into fine size. VSI crusher is used to crush the relative hard materials. In the whole production process, the vibrating feeder, vibrating screen and belt conveyor work together with the main crushing equipment to complete the mining process.
Stone crusher machine costs are the important factor for clients to choose the suitable processing crusher equipment. Providing customers high quality equipment and low stone ore crusher price is our goal. Depending on years' experience and high technology, SBM has manufactured a series of crushing machine to satisfy different customers' needs.
As a famous and professional stone crusher supplier, SBM can provide the advanced stone crushing machine to all the contractors. Stone crushers feature large crushing rate, high yield, equal product size, simple structure, reliable operation and easy maintenance, economic operating costs etc.
SBM always tries its best to produce the advanced machines to increase capacity without significantly increasing operating costs-that's the goal of mining and aggregate products through the world. SBM's stone crusher puts that goal within easy reach. It stands for maximum power, and no similarly-sized conventional crusher can match the performance of the general cone crusher.
Jaw crusher is widely used to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, marble, etc. It can reach the crushing ratio of 4~6 and the shape of final product is even. The pressure resistance strength is under 200Mpa, which is suitable for primary crushing.
Cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, etc. Cone crusher consists of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.
Impact crusher is the better choice for crushing and screening stones. The impact crusher features reasonable structure, high productivity, easy operation and maintenance and safe performance. The most outstanding advantage of the impact crusher is that its finished power is in good, cubic shape and with tensility and cranny.
The types of pressure crushers include jaw crusher, roller crusher, and gyratory crusher. The pressure type crusher uses two hard parts of the machine to press each other to crush rock material. For example, the jaw crushers use the fixed jaw plant and movable jaw plate.
The jaw crusher's main function is to reduce the size of the raw materials or large pieces of material to a sufficiently small size, so as to facilitate the next step of the crushed material. In the quarries and mine materials crushing plant, it is generally used as a primary crusher. The types of jaw crushers are single toggle and double toggle. The construction of the single toggle jaw crusher is compact and simple, and the transmission components such as eccentric shafts are less stressed. Due to the vertical displacement of the movable jaw is small, the material is less excessively broken during processing. Therefore, the wear of the movable jaw plate is less.
Compared with the simple pendulum type, the double toggle type jaw crusher has the advantages of lighter weight, fewer components, a more compact structure and uniform crushing, high productivity. 20-30% higher productivity than a simple swing jaw crusher of the same specification.
Tooth Roller crusher is a new product that is designed and developed according to the structure principle of Gunlock crusher in America. The machine has the advantages of small volume, high crushing ratio (5-8) , low noise, simple structure, convenient maintenance, high productivity, even particle size of crushed materials, low over crushing rate, convenient maintenance, etc. The mall roller crusher is widely used in the mining industry as a secondary crusher.
Gyratory crusher is a new type of crusher that can replace fine jaw crusher and cone crusher. It consists of a concave surface and a conical head, both of which are usually lined with manganese steel. The inner cone has a slight circular movement but doesn't rotate. The gyratory has the advantages of good finely crushing effect, large processing capacity, small vibration, simple maintenance, low cost, and less lining plate wear.
Impact crushers crush materials by impact rather than by pressure. The material is broken in the crushing chamber under the impact force. It can handle materials with side length less than 100-500 mm, with compressive strength up to 350 MPA. It has the advantages of a large crushing ratio and cubic particles after crushing. There are two types of impact crushers: Horizontal Shaft Impact(HSI) Crushers and Vertical Shaft Impact(VSI) Crushers.
In the sand making plant is one of the essential crushers. Cone crusher according to the crushing force is divided into Simmons spring type and hydraulic type. Hydraulic type is divided into single-cylinder and multi-cylinder cone crusher. According to the rotary speed, there are three types: low speed, medium speed and high speed.
The basic structure of cone crusher is similar to that of rotary crusher, but the range is larger. It rotates and presses against the stone on the side of the machine, where it falls into the lower chamber and is crushed again until it falls out of the bottom. Its advantages: reliable structure, high productivity, easy adjustment, and low operation cost.
Hammer crusher(Hammer mill) is broken by an impact between a high-speed hammer and material. This type of crusher is divided into two types: single rotor and double rotor. Single Rotor is divided into reversible and irreversible. Hammer crusher is mainly composed of the rotor, spindle, hammerhead, lining plate and impact plate. And it mainly crushing for coal, salt, chalk, gypsum, brick, limestone and so on. It also used for crushing fiber structure, flexibility, and toughness of strong broken wood, paper, etc.
The advantages of the hammer: larger crushing ratio, high production capacity, uniform products, less over-powder phenomenon, simple structure, light equipment quality, simple operation, and maintenance.
Sand crusher is also called VSI crusher. It is an indispensable equipment for artificial sand manufacturing plant. VSI crusher imported advanced German technology development and production, with the international advanced level. Its performance plays an irreplaceable role in the fine crushing equipment of various materials. There are two types of sand-making machine: stone hit stone and stone hit steel.
The upper and lower hitting guard plate is installed on the crushing cavity wall of the sand making machine. It makes the ore material to be crushed by the impact, friction or high-speed impact between the material and the lining layer formed by the material and the material accelerated by the flywheel when accelerating. The materials do not come into direct contact with the equipment. This method reduces the wear and tear of fittings and prolongs the service life. "Stone hit stone" sand crusher is suitable for material with high abrasion above medium hardness, such as basalt. And the finished product has good grain shape, but the powder content is a little more. So it is more suitable for aggregate shaping.
In the crushing cavity wall of the sand-making machine, the lower hitting guard plate is replaced by the perimeter guard plate. When the ore material is thrown out by the roller, it is directly impacted on the guard plate for many times and the crusher. Under the constant impact, and then the crushing cavity material impact, ore material broken more fully, and the finished material particle size smaller. The "stone hit steel" sand crusher is suitable for small abrasive materials below medium hardness, such as limestone, and the crushing efficiency is high. However, due to crushing depends on the impact, so wear parts are higher. The finished product is slightly worse, it is more suitable for sand-making.
