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 isn8217t as critical. As the performance of this type of screen isn8217t good enough to meet the requirements of most mining operations two variations of this screen has 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.
The pattern of vibration for the horizontal screen deck is back and forth while the inclined vibrating screen is circular.There are different ways to generate the vibration itself. A double counterbalance system is used in the horizontal screen.
The counterbalance weight will alternately promote and retard the direction of vibration depending upon where within each revolution the weights come opposite each other.
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.
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 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.
Vibrating screen is a mechanical equipment that uses vibrating screen panels to classify the mixture which contain different particles according to particle size.
According to different structure and use vibrating screens usually be devided into many types by the vibrating screen manufacturers. Below wil introduce the top 10 vibrating screens and how to choose the right vibratory screen
linear vibrating screen is driven by double vibrating motors. When the two vibrating motors are rotating synchronously and reversely the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor and overlaps into a resultant force in the direction perpendicular to the axis of the motor so the motion track of the linear vibrating screen machine is a straight line.
Circular vibrating screen is a new type of vibrating screen with multi-layer screen and high efficiency. According to the type of materials and the requirements of users the high manganese steel woven screen punched screen plate and rubber screen plate can be used. The circular vibrating screen is installed in the seat type. The adjustment of the screen surface angle can be realized by changing the position and height of the spring support.
Working Principle The motion track of the screen box of the circular vibrating screen is circular. The circular vibrating screen uses the inertia exciter to produce vibration. The main shaft fixed on the screen box is driven by the motor to rotate at high speed and the eccentric body installed on the main shaft rotates with it generating centrifugal inertia force so that the screen box that can freely vibrate will produce vibration similar to the circular track.
Circular vibrating screen is widely used in the materials classification of mining building materials transportation energy chemical industry and other industries because of its long flowing line and many screening specifications.adsbygoogle window.adsbygoogle .push
Working Principle The power is transmitted from the motor to the main shaft of the exciter and the gear vibrator speed ratio is 1 through the V-belt so that the three shafts can rotate at the same speed and generate the exciting force. The exciter is connected with the high-strength bolts of the screen box resulting in elliptical movement.
Materials on the screens do high-speed elliptical movement along with the screen machine so as to achieve uickly separate sift and move forward and ultimately complete the classification of materials.

What are vibrating screens and which are its main applications for use. Also called simply screens a vibrating screen is formed by avibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size starting from a bulk product in a continuous process.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Hongxing cone crusher is used for crushing ores and rocks and the advantages are reliable structure high efficiency easy adjustment and economy.
Sand maker is suitable for the crushing of soft hard and extremely hard material and reshape of those products.
