WFHS reversible arc screen for mining ore

Working principle and structure characteristics:

The utility model is mainly composed of an arc-shaped stainless steel screen surface, a screen frame and a supporting seat. The middle position of the screen frame center axis of rotation, the screen frame can make the center of the rotary shaft to rotate 180 degrees, without removing the screen change direction, thereby prolonging the service life of the screen. Coal slurry screen surface movement along the arc, each over a sieve, sieve and liquid flow due to the side impact angle, the screen angle of the powder surface tension in water have been destroyed, so there is a part of the water and fine cut down as siftage.

Applications:

1.WFHS reversible arc screen is used in the coal industry, a fine-grained material dewatering, sculping, desliming grading equipment.

2.Mainly used in coal preparation plant, generally used in conjunction with heavy medium cyclone.

3.Can also be used in metallurgy, chemical industry, the material dewatering, sculping, desliming, grading and recycling.

Principle:

1.Reversible arc screen is mainly composed of curved stainless steel sieve surface and screen frame and support.

2.The center of the screen frame has a central rotation axis, the screen frame can rotate the center rotation axis 180 degrees, the sieve mesh does not demolition exchange direction, thereby extending the service life of the sieve surface.

3. Coal slurry along the curved screen surface movement, each over a screen bar, as the liquid flow and the screen side of the sharp corners of the impact, in the sieve bars angle between the particle surface, water tension is damaged, part of the water and fine particles are cut down to achieve the purpose of screening.

4.Reversible arc screen dewatering principle is to rely on the screen into the material side of the edge of the cutting edge of the role of slime, the slime water separation.

5.Reversible arc screen can be reversed from the feeding box, sieve box and sieve machine seat axis to realize the reversed position of the feeding end and the discharging end to achieve uniform wear and prolong service life.

Features:

1. Long service life, flexible operation and convenient.

2. High screening efficiency, not easy to plug holes, high rate of openings.

3. Dewatering effect is good, energy saving and environmental protection.
