Industrial Common Ore Screening Equipment

Rotary screen is used for screening every kind of coarse impurities, especially for getting rid of light impurities in tailing slag.

Main features of Rotary Sieve:

1. Eccentric oscillator inside sleeve, non corrosion and safe

2. Two rolls of self aligning, long lifetime spring

3, Good screening ability, vibrating, self-cleaning, high efficiency, easy and simple handling convenient 

Working Principle of Rotary Screener:

When the vibrating screen is working, the two engines rotate oppositely to make the vibrating exciter produce the exciting force, which makes the materials throw forward periodically to finish the screening. It is suitable for the screening of stones in the stone pit as well as for the screening of coals dressing, ores dressing, materials building, electricity and chemistry.

The working part of the vibrating screen is stationary, while the screening is made by the sliding of the materials along the mining face. The fixed lattice sieve is a frequently used screen in ores dressing, which is always used for coarse crushing or advanced screening before medium crushing. Its structure is simple, thus it is easy to be made. The main disadvantage is the low production ratio and low efficiency of screening with only 50% to 60%

Rotary screen is often used in screening gravel, ore and stone. Gravel screen is designed on the basis of ore screening equipment, and stone separator is the most popular in the modern market.
