In the mineral processing area, the trommel screens(aka. Rotary drum screens) and vibrating screens are both widely used screening & classification equipment. But whats the difference between the trommel screens and vibrating screens, and how to choose the most suitable screens for your mineral processing application? Or even how should we choose the right screening equipment for specific mining conditions?
Thorough we all may know that they are both are widely used screening equipment, but the different working methods and principles also mean the difference in output, as well as the types of materials suitable for screening processing.
Vibrating screens are screened using the exciting force generated by a vibrating motor and belong to vibrating screens. Commonly used mine vibrating screens include circular vibrating screens and linear screens.
The trommel screen is another screening form. During the screening process, the equipment will not vibrate, but generally, the motor and reducer drive the drum to rotate through the bearing. The material in the drum passes through the screen from high to low due to the rotation of the drum. And it is successfully screened out, so the trommel screen belongs to a type of rolling screening.
trommel screen: It is a cylinder. The outer surface of the cylinder uses one or more layers, or several sections of screens to increase the screening specifications. The volume of the trommel screen is generally large, mainly including motors, reducers, drum devices, screens, and machines. It is composed of a frame, a sealing cover, and an inlet and an outlet. A steel ring must be added to the drum device to prevent the trommel screen from deforming.
The roller device is installed on the frame obliquely. The motor is connected with the roller device through a coupling through a reducer, and drives the roller device to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned and rolled. The qualified materials (products under the screen) are discharged through the outlet at the bottom of the rear end of the drum, and the unqualified materials (on the screen) The product is discharged through the discharge port at the end of the drum.
Using the vibration motor as the vibration source, the material is thrown up on the screen while moving forward in a straight line. The material enters the inlet of the screening machine evenly from the feeder, and produces several kinds of screens through the multi-layer screen. The upper and lower objects are discharged from their respective outlets.
The screen surface is fixed on the screen box, and the screen box is suspended or supported by springs. The bearing of the main shaft is installed on the screen box and is driven by the pulley to rotate at high speed. The eccentric counterweight plate is installed on the main shaft and generates centrifugal inertia force with the rotation of the main shaft, so that the screen box forms an approximate circular orbit vibration.
The trommel screen can be divided into single-layer, double-layer and three-layer vibrating screens according to the number of layers of the screen. This vibrating screen is also similar, according to the number of screen surface layers can be divided into single-layer, double-layer, three-layer and four-layer vibrating screen.
The vibrating screen is a screening equipment with a vibrating motor as the vibration source, so the screening accuracy is high. The trommel is a high-output screening equipment, and the screening accuracy is not as high as the vibrating screen.
For the trommel screen, the material is turned over and rolled in the drum, so that the material stuck in the sieve hole can be ejected to prevent the sieve hole from being blocked. For the circular vibrating screen, the material moves in a parabolic circular trajectory on the screen surface, so that the material is dispersed as much as possible to improve the materials bounce force, and the material stuck in the screen hole can also jump out, reducing the hole blocking phenomenon.
Vibrating screen and trommel screen have their own working methods and screening principles. Some raw materials can be screened through them. However, for different sites and different material requirements, suitable screening machines should be selected to achieve better screening results.
When the smaller rock has to be classified a vibrating screen will be used.The simplest Vibrating Screen Working Principle can be explained using the single deck screen and put it onto an inclined frame. The frame is mounted on springs. The vibration is generated from an unbalanced flywheel. A very erratic motion is developed when this wheel is rotated. You will find these simple screens in smaller operations and rock quarries where sizing isnt as critical. As the performance of this type of screen isnt good enough to meet the requirements of most mining operations two variations of this screen have been developed.
In the majority of cases, the types of screen decks that you will be operating will be either the horizontal screen or the inclined vibrating screen. The names of these screens do not reflect the angle that the screens are on, they reflect the direction of the motion that is creating the vibration.
An eccentric shaft is used in the inclined vibrating screen. There is an advantage of using this method of vibration generation over the unbalanced flywheel method first mentioned. The vibration of an unbalanced flywheel is very violent. This causes mechanical failure and structural damage to occur. The four-bearing system greatly reduces this problem. Why these screens are vibrated is to ensure that the ore comes into contact will the screen. By vibrating the screen the rock will be bounced around on top of it. This means, that by the time that the rock has traveled the length of the screen, it will have had the opportunity of hitting the screen mesh at just the right angle to be able to penetrate through it. If the rock is small enough it will be removed from the circuit. The large rock will, of course, be taken to the next stage in the process. Depending upon the tonnage and the size of the feed, there may be two sets of screens for each machine.
The reason for using two decks is to increase the surface area that the ore has to come into contact with. The top deck will have bigger holes in the grid of the screen. The size of the ore that it will be removed will be larger than that on the bottom. Only the small rock that is able to pass through the bottom screen will be removed from the circuit. In most cases the large rock that was on top of each screen will be mixed back together again.
The main cause of mechanical failure in screen decks is vibration. Even the frame, body, and bearings are affected by this. The larger the screen the bigger the effect. The vibration will crystallize the molecular structure of the metal causing what is known as METAL FATIGUE to develop. The first sign that an operator has indicated that the fatigue in the body of the screen deck is almost at a critical stage in its development are the hairline cracks that will appear around the vibrations point of origin. The bearings on the bigger screens have to be watched closer than most as they tend to fail suddenly. This is due to the vibration as well.
In plant design, it is usual to install a screen ahead of the secondary crusher to bypass any ore which has already been crushed small enough, and so to relieve it of unnecessary work. Very close screening is not required and some sort of moving bar or ring grizzly can well be used, but the modern method is to employ for the purpose a heavy-duty vibrating screen of the Hummer type which has no external moving parts to wear out ; the vibrator is totally enclosed and the only part subjected to wear is the surface of the screen.
The Hummer Screen, illustrated in Fig. 6, is the machine usually employed for the work, being designed for heavy and rough duty. It consists of a fixed frame, set on the slope, across which is tightly stretched a woven-wire screen composed of large diameter wires, or rods, of a special, hard-wearing alloy. A metal strip, bent over to the required angle, is fitted along the length of each side of the screen so that it can be secured to the frame at the correct tension by means of spring-loaded hook bolts. A vibrating mechanism attached to the middle of the screen imparts rapid vibrations of small amplitude to its surface, making the ore, which enters at the top, pass down it in an even mobile stream. The spring-loaded bolts, which can be seen in section in Fig. 7, movewith a hinge action, allowing unrestricted movement of the entire screening surface without transmitting the vibrations to the frame.
One, two, or three vibrators, depending on the length of the screen, are mounted across the frame and are connected through their armatures with a steel strip securely fixed down the middle of the screen. The powerful Type 50 Vibrator, used for heavy work, is shown in Fig. 7. The movement of the armature is directly controlled by the solenoid coil, which is connected by an external cable with a supply of 15-cycle single-phase alternating current ; this produces the alternating field in the coil that causes the up-and-down movement of the armature at the rate of thirty vibrations per second. At the end of every return stroke it hits a striking block and imparts to the screen a jerk which throws the larger pieces of ore to the top of the bed and gives the fine particles a better chance of passing through the meshes during the rest of the cycle. The motion can be regulated by spiral springs controlled by a handwheel, thus enabling the intensity of the vibrations to be adjusted within close limits. No lubrication is required either for the vibrating mechanism or for any other part of the screen, and the 15-cycle alternating current is usually supplied by a special motor-generator set placed somewhere where dust cannot reach it.
The Type 70 Screen is usually made 4 ft. wide and from 5 to 10 ft. in length. For the rough work described above it can be relied upon to give a capacity of 4 to 5 tons per square foot when screening to about in. and set at a slope of 25 to 30 degrees to the horizontal. The Type 50 Vibrator requires about 2 h.p. for its operation.
The determination of screen capacity is a very complex subject. There is a lot of theory on the subject that has been developed over many years of the manufacture of screens and much study of the results of their use. However, it is still necessary to test the results of a new installation to be reasonably certain of the screen capacity.
A general rule of thumb for good screening is that: The bed depth of material at the discharge end of a screen should never be over four times the size opening in the screen surface for material weighing 100 pounds per cubic foot or three times for material weighing 50 pounds per cubic foot. The feed end depth can be greater, particularly if the feed contains a large percentage of fines. Other interrelated factors are:
Vibration is produced on inclined screens by circular motion in a plane perpendicular to the screen with one-eighth to -in. amplitude at 700-1000 cycles per minute. The vibration lifts the material producing stratification. And with the screen on an incline, the material will cascade down the slope, introducing the probability that the particles will either pass through the screen openings or over their surface.
Screen capacity is dependent on the type, available area, and cleanliness of the screen and screenability of the aggregate. Belowis a general guide for determining screen capacity. The values may be used for dried aggregate where blinding (plugged screen openings), moisture build-up or other screening problems will not be encountered. In this table it is assumed that approximately 25% of the screen load is retained, for example, if the capacity of a screen is 100 tons/hr (tph) the approximate load on the screen would be 133 tph.
It is possible to not have enough material on a screen for it to be effective. For very small feed rates, the efficiency of a screen increases with increasing tonnage on the screen. The bed of oversize material on top of the marginal particlesstratification prevents them from bouncing around excessively, increases their number of attempts to get through the screen, and helps push them through. However, beyond an optimum point increasing tonnage on the screen causes a rather rapid decrease in the efficiency of the screen to serve its purpose.
Two common methods for calculating screen efficiency depend on whether the desired product is overs or throughs from the screen deck. If the oversize is considered to be the product, the screen operation should remove as much as possible of the undersize material. In that case, screen performance is based on the efficiency of undersize removal. When the throughs are considered to be the product, the operation should recover as much of the undersize material as possible. In that case, screen performance is based on the efficiency of undersize recovery.
These efficiency determinations necessitate taking a sample of the feed to the screen deck and one of the material that passes over the deck, that is, does not pass through it. These samples are subjected to sieve analysis tests to find the gradation of the materials. The results of these tests lead to the efficiencies. The equations for the screen efficiencies are as follows:
In both cases the amount of undersize material, which is included in the material that goes over the screen is relatively small. In Case 1 the undersize going over the screen is 19 10 = 9 tph, whereas in Case 2 the undersize going over is 55 50 = 5 tph. That would suggest that the efficiency of the screen in removing undersize material is nearly the same. However, it is the proportion of undersize material that is in the material going over the screen, that is, not passed through the screen, that determines the efficiency of the screen.
In the first cases the product is the oversize material fed to the screen and passed over it. And screen efficiency is based on how well the undersize material is removed from the overs. In other cases the undersize material fed to the screen, that is, the throughs, is considered the product. And the efficiency is dependent on how much of the undersize material is recovered in the throughs. This screen efficiency is determined by the Equation B above.An example using the case 1 situation for the throughs as the product gives a new case to consider for screen efficiency.
Generally, manufacturers of screening units of one, two, or three decks specify the many dimensions that may be of concern to the user, including the total headroom required for screen angles of 10-25 from the horizontal. Very few manufacturers show in their screen specifications the capacity to expect in tph per square foot of screen area. If they do indicate capacities for different screen openings, the bases are that the feed be granular free-flowing material with a unit weight of 100 lb/cu ft. Also the screen cloth will have 50% or more open area, 25% of total feed passing over the deck, 40% is half size, and screen efficiency is 90%. And all of those stipulations are for a one-deck unit with the deck at an 18 to 20 slope.
As was discussed with screen efficiencies, there will be some overs on the first passes that will contain undersize material but will not go through the screen. This material will continue recirculating until it passes through the screen. This is called the circulating load. By definition, circulating load equals the total feed to the crusher system with screens minus the new feed to the crusher. It is stated as a percentage of the new feed to the crusher. The equation for circulating load percentage is:
To help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher. Assume 100% screen efficiency and 30% oversize in the crusher input. For the successive cycles of the circulating load:
The values for the circulating load percentages can be tabulated for various typical screen efficiencies and percents of oversize in the crusher product from one to 99%. This will expedite the determination for the circulating load in a closed Circuit crusher and screening system.
Among the key factors that have to be taken into account in determining the screen area required is the deck correction. A top deck should have a capacity as determined by trial and testing of the product output, but the capacity of each succeeding lower deck will be reduced by 10% because of the lower amount of oversize for stratification on the following decks. For example, the third deck would be 80% as effective as the top deck. Wash water or spray will increase the effectiveness of the screens with openings of less than 1 in. in size. In fact, a deck with water spray on 3/16 in. openings will be more than three times as effective as the same size without the water spray.
For efficient wet or dry screeningHi-capacity, 2-bearing design. Flywheel weights counterbalance eccentric shaft giving a true-circle motion to screen. Spring suspensions carry the weight. Bearings support only weight of shaft. Screen is free to float and follow positive screening motion without power-consuming friction losses. Saves up to 50% HP over4- bearing types. Sizes 1 x 2 to 6 x 14, single or double deck types, suspended or floor mounted units.Also Revolving (Trommel) Screens. For sizing, desliming or scrubbing. Sizes from 30 x 60 to 120.
TheVibrating Screen has rapidly come to the front as a leader in the sizing and dewatering of mining and industrial products. Its almost unlimited uses vary from the screening for size of crusher products to the accurate sizing of medicinal pellets. The Vibrating Screen is also used for wet sizing by operating the screen on an uphill slope, the lower end being under the surface of the liquid.
The main feature of the Vibrating Screen is the patented mechanism. In operation, the screen shaft rotates on two eccentrically mounted bearings, and this eccentric motion is transmitted into the screen body, causing a true circular throw motion, the radius of which is equivalent to the radius of eccentricity on the eccentric portion of the shaft. The simplicity of this construction allows the screen to be manufactured with a light weight but sturdy mechanism which is low in initial cost, low in maintenance and power costs, and yet has a high, positive capacity.
The Vibrating Screen is available in single and multiple deck units for floor mounting or suspension. The side panels are equipped with flanges containing precision punched bolt holes so that an additional deck may be added in the future by merely bolting the new deck either on the top or the bottom of the original deck. The advantage of this feature is that added capacity is gained without purchasing a separate mechanism, since the mechanisms originally furnished are designed for this feature. A positivemethod of maintaining proper screen tension is employed, the method depending on the wire diameter involved. Screen cloths are mounted on rubber covered camber bars, slightly arched for even distribution.
Standard screens are furnished with suspension rod or cable assemblies, or floor mounting brackets. Initial covering of standard steel screen cloth is included for separations down to 20 mesh. Suspension frame, fine mesh wire, and dust enclosure are furnished at a slight additional cost. Motor driven units include totally-enclosed, ball-bearing motors. The Vibrating Screen can be driven from either side. The driven sheave is included on units furnished without the drive.
The following table shows the many sizes available. Standard screens listed below are available in single and double deck units. The triple and quadruple deck units consist of double deck units with an additional deck or decks flanged to the original deck. Please consult our experienced staff of screening engineers for additional information and recommendations on your screening problems.
An extremely simple, positive method of imparting uniform vibration to the screen body. Using only two bearings and with no dead weight supported by them, the shaft is in effect floating on the two heavy-duty bearings.
The unit consists of the freely suspended screen body and a shaft assembly carried by the screen body. Near each end of the shaft, an eccentric portion is turned. The shaft is counterbalanced, by weighted fly-wheels, against the weight of the screen and loads that may be superimposed on it. When the shaft rotates, eccentric motion is transmitted from the eccentric portions, through the two bearings, to the screen frame.
The patented design of Dillon Vibrating Screens requires just two bearings instead of the four used in ordinary mechanical screens, resulting in simplicity of construction which cuts power cost in half for any screening job; reduces operating and maintenance costs.
With this simplified, lighter weight construction all power is put to useful work thus, the screen can operate at higher speeds when desired, giving greater screening capacity at lower power cost. The sting of the positive, high speed vibration eliminates blinding of screen openings.
The sketches below demonstrate the four standard methods of fastening a screen cloth to the Dillon Screen. The choice of method is generally dependent on screen wire diameters. It is recommended that the following guide be followed:
Before Separation can take place we need to get the fine particles to the bottom of the pile next to the screen deck openings and the coarse particles to the top. Without this phenomenon, we would have all the big particles blocking the openings with the fines resting atop of them and never going through.
We need to state that 100% efficiency, that is, putting every undersize particle through and every oversize particle over, is impossible. If you put 95% of the undersize pieces through we in the screen business call that commercially perfect.

Description Vibrating screen is a kind of mine classification machine for ore, mine, sand, gravel, coal, slurry, etc. which consists of a screen and a vibrator. Generally below 50 mesh for the coarse screen, 80 mesh for the fine screen. The vibrator is an eccentric wheel that rotates under the drive of the motor, making the sieve frame vibrate. Because of the vibration of the sieve frame, the thicker solid particles left on the sieve surface when they flow to the sieve surface, and discharged from one end along the sloping surface. The finer solid particles and the mud liquid flow through the sieve hole to the mud pond together.
Types of vibrating screens vibrating sieve can be divided into mining vibrating screen, light fine vibrating screen, experimental vibrating screen, also can be divided into the linear vibrating screen, circular vibrating screen, high frequency vibrating screen, double deck vibrating screen, single deck vibrating screen and so on. The vibratory screen is widely used in coal and other industries, used as a material classification, mineral washing, dehydration, screening machine. It is widely used in mining, coal, smelting, building materials, refractory, light industry and chemical industry for its high production efficiency, good classification effect, and convenient maintenance. You may be interested in other mineral grading equipment. JXSC, over 30 years vibrating screen manufacturer, provides custom vibrating screen design service.
Vibrating Screen Machine Working PrincipleVibrating screen uses electric exciter as a vibrating source, the material will be thrown around the screen, at the same time doing forward sports, in order to achieve the screening purpose. Material from the feeder evenly enters into the machine's feeding inlet, with multilayer sieves to produce various products and unqualified products on the screen or under the screen, then discharging from the outlet respectively. It can be used in the automatic production line. In the working process, the dynamic performance of the vibrating screen directly affects the screening efficiency and service life. The vibrating screen uses the vibration excited by the vibrating motor as the vibration source so that the material is thrown up on the screen Mesh and moves forward in a straight line Through the multi-layer screen to produce a number of the screen on the screen, screen under the material, respectively from their respective export discharge.

Discrimination Mode - This mode is the default mode and is the mode most commonly used for continuous searching. Like most modern metal detectors, it requires the searchcoil to be in motion in order to detect and identify targets. In this mode, targets are identified with distinct tones, and are classified in categories at the bottom of the display. All menu items can be selected, customized or changed in this mode. The discrimination mode is a cumulative elimination system. Targets can be eliminated from left to right on the scale.
Notch Discimination Mode - In this mode, the user can selectively eliminate individual targets. While the Discrimination Mode eliminates all categories sequentially from detection; the Notch control allows you to selectively include or exclude individual target categories from detection.
Sensitivity Control - Increase or decrease the sensitivity of the detector at the touch of a button. Sensitivty on a metal detector is also known as depth. The sensitivity control helps you to fine tune the detector for the best operation.

We look forward to our future relationship and continued success of MetalDetector.com and their entire staff.
I recently had the pleasure of meeting with the team at MetalDetector.com at their newly expanded facility in Southborough, MA. I have to say that I was impressed with their operation and knowledge of the Teknetics product line. When the Teknetics product line was recently re-launched, MetalDetector.com was one of the first partners we contacted. They have had a long standing relationship with the brand as one of the original Teknetics dealers in the country. We value long standing relationships and are excited to have them as a member of our team.
It's been an honor and privilege working with the fine folks at Detector Electronics for over 25 years. Having a family owned and run business ourselves, we know the "attention to detail" it takes to keep a business running smoothly with an emphasis on customer service. It's no surprise that Sondra and David's fine sons, Michael and Daniel have continued in their parents tradition of being exemplary businesspeople who take the time and care enough to really know their clientele. It's always been a pleasure working with you!

They provide exceptional support and service to our customers. They are a recognized leader in the industry. Internationally their business is known for excellent customer support.

Dear Sondra, ...in addition to being the first metal detector company I found (after contacting several) which actually seemed to care about my order and which treated me like a valued customer, you also really worked hard from your end to make sure the purchase went through and the detector arrived at its destination on time. By the end I felt I was dealing with a friend rather than a faceless company on the net. Well done!
And, by the way, my 7 year old son Juanito found a nickel yesterday when he took his detector out for the first time! If things keep going this way the detector will have paid for itself within a few short decades! But seriously, he is really enjoying it and hoping to find his long-dreamed-of buried treasure some day.
Ordered 2 Garrett ACE 250's on 09-14-09 at noon Received 09-15-09 at noon You folks should be proud that you hold true to all you say, do and promise. It's very refreshing to work with a company that keeps the old-world values going, not too many people / companies out there that can even come close to what you provide.
1160 GRAM Meteorite! found 3 " underground. Don't ask where. One of many! As far as being excited I all most had a stroke. Here's a photo of one Meteorite I found on the surface, over 800 grams and a 447 gram one! The one in the middle is my first. The bar magnet has some small Iron meteorites on it.
I received the Tesoro Sand Shark today...and want to thank you. Tried it, love it, looking forward to many enjoyable hours with it. Knowing that it is a "rare" domestically made item gives me double pleasure! Also...doing business with pro's (such as yourselves) was also a pleasure I will tell others about! Forwarded a "glowing review" to you. Thanks again.
Just wanted to thank all involved in a recent shipment to me that was a gift for my grandkids. I ordered 2 detectors but for some reason only one was shipped. After calling your company you bent over backwards to get the second detector to me on time for giving to my grandchildren. I explained that we exchange gifts a week early so my children and their families can be in their homes Christmas morning since some travel distances are involved. The second detector arrived last Friday in time for our celebration last Saturday. --THANKYOU. I order quite a few things online and have experienced some terrible companies but you are the best.
I have just come in after spending an hour or at my local beach with my son, which is only a 5 minute walk from my home called Deception Bay. This is the first time i have ever used detector. The very first thing it detected in less than a minute was a two dollar coin, boy we were so excited! Not by the amount, but by the fact that on its maiden voyage it detected a coin. We then detected a ten cent piece. We can't wait to take it to a popular beach and I will practice more with the settings.
I would like to thank you for your prompt service. My detector arrived at my door In Brisbane Australia in less than a week. This is the first time I have used any service like this outside of Australia, but with this kind of service and ease of buying and your range of goods this will be the first of many transactions.
I just wanted to say thank you to Scott who made my recent purchase so pleasent! I am enjoying my Tesoro's and have found lots of cool stuff so far. Just waiting for that first gold find! Thanks agian for all the help that was provided in making my decision!
I was amazed at how fast I received my BOUNTY HUNTER. The order arrived in perfect condition, and in only three days after I placed the on line order. The four part series about selecting the right product was also appreciated and helped me to make the right decision for my purchase. You are truly a company that takes care of business and most importantly your customers. It is a pleasure doing business with you and I will gladly recommend you to anyone that wants to buy a metal detector. Thanks for the GREAT SERVICE.
I am a very happy camper. Yesterday I took my Garrett Ace 250 out for the first time to some local parks. My total find was about 150 coins. The detector works so well and so easily. It only took me about a half an hour before I new what every button did. I am also very salified with the support I got from Dan & Sondra.
I purchased an Ace 250 from your site for my 7 year old son and now I am hooked! This is our first metal detector and the Ace does every thing it says it will. Thanks for the fast delivery and introducing my son and I to a great new hobby.
I got the detector-my husband was thrilled.... Thank you so much. You and Daniel have been so helpful. I am a first time buyer and am feeling very lucky to have found your website. Daniel helped me to locate a really great detector and you have been extremely courteous and prompt in seeing my order through. I look forward using my new metal detector. Hope you have a wonderful holiday season....overall my experience ordering off of your website was convenient and customer service was great. Thanks again.
