The working principle and characteristics of rotary sieve

First, the rotary screen works:

Rotary sieve mainly motor, reducer, drum device, rack and other institutions. The drum unit is tilted. The motor is connected to the drum mechanism by means of a reducer, which drives the drum mechanism to rotate about its axis. When the material into the drum device, due to the drum device tilt and rotation, so that qualified materials (screen products) by the drum outside the screen discharge, unqualified materials (sieve products) by the end of the drum discharge. Rotary sieve drum device through the body seal cover, so as to ensure that the equipment in the course of work, effectively prevent the dust outside the escape, to prevent dust pollution. Replace the screen, just open the body seal can be replaced, easy to operate.

Second, the rotary screen Features:

1, material adaptability Wide rotary sieve is widely used in various types of material screening, whether it is low quality coal, slime, or soot and other materials, are smooth screening.
2, the feeding method is simple and diverse rotary sieve inlet can be designed according to the actual site, whether it is belt, funnel or other feeding methods, do not take special measures, can be smooth feeding.
3, high screening efficiency equipment can be equipped with comb-type screening mechanism, in the screening process, regardless of the material into the screening cylinder dirty, more heterogeneous can be sifted, thereby improving the efficiency of the equipment screening.
4, the screening of large, easy to large size in the same size, the area is larger than the other types of area, so the effective area of the sieve on the large, so that the material can fully contact the screen, so the unit time the amount of sieve The But also because of its simple structure, easy layout, new technology and mature features, easy to large-scale.
5, their own energy consumption Small rotary screen motor power is small, is the other sieve type of one-half to one third, the same amount of material and the running time is only half of the other sieve type, so low energy consumption.
6, the working environment is good The entire screening tube can be sealed with a sealed cover, completely remove the sieving process of dust flying, block splashing and so on, to avoid the work environment pollution.
7, equipment noise low rotary sieve in operation, due to the small rotation speed, and a sealed isolation cover with the outside world, so that noise can not be transmitted to the outside, thereby reducing the equipment noise.
8, long service life, maintenance of small rotary sieve is composed of a number of ring-shaped mesh, the total screening area is much larger than the other sieve type sieve area, coupled with high screening efficiency, equipment running time is short, So the service life is longer, less wearing parts, maintenance of small.
9, easy maintenance equipment sealed isolation cover can be opened, open does not affect the normal operation of the machine, and makes maintenance is very convenient.
