Interlaced toothed rotor design used in mining

A vibrating screen or sieve can be basket shaped, cylindrical, flat, curved, or an irregular shape. There are flat bed designs which are inclined so as to use gravity during the screening process.

The size of the equipment will vary depending upon the weight and dimensions of the materials that are to be cleaned or sorted.
The Three-Stage Breaking Action: Initially, the material is gripped by the leading faces of opposed rotor teeth. These subject the rock to multiple point loading, inducing stress into the material to exploit any natural weaknesses. At the second stage, material is broken in tension by being subjected to a three point loading, applied between the front tooth faces on one rotor, and rear tooth faces on the other rotor. Any lumps of material that still remain oversize, are broken as the rotors chop through the fixed teeth of the breaker bar, thereby achieving a three dimensional controlled product size.
The Rotating Screen Effect: The interlaced toothed rotor design allows free flowing undersize material to pass through the continuously changing gaps generated by the relatively slow moving shafts.
The Deep Scroll Tooth Pattern: The deep scroll conveys the larger material to one end of the machine and helps to spread the feed across the full length of the rotors. This feature can also be used to reject oversize material from the machine.
A vibrating screen or sieve plays an essential role in industries that involve classifying, separating, sizing, and sorting various materials. They are important in both manufacturing and industrial domains. Their size, design, weight, and operation method can vary dramatically; this is important as they can then provide the maximum possible efficiency for whatever use they are put to. In general terms vibratory sieves and screens are used in the initial processing stage of various raw materials as well as in recycling plants and occasionally in environmental clean up operations.
The actual vibrating action can be controlled through pressing, rolling, or shaking. In some cases water will also be used to reduce the effort involved. There are also a few designs that integrate centrifugal force into their operation.
You can also incorporate a vibrating sieve or screen into your business to cut down on wastage. It is now not unusual to find industries that reuse such products as machine oil and coolant. Over time industrial liquids can become contaminated by dirt such as small metal filings. It is even possible to separate thick oil from water using some screens and sieves.
