What Screen is Used in the Feed Industry--the Gyratory Screen

At present, most feed manufacturers need to sieve and grade the powder material ,granular feed, and the intermediate products after secondary crushing. The quality and output of the feed products are directly affected by the classification and the performance of the equipment. What screen is commonly used in the feed industry? The answer is the gyratory screen. It is widely used in feed industry due to its simple structure, large output, convenient maintenance, low noise.
Under the inertia force, gyratory screen sieve box moves back and forth, driving the screen surface shaking periodically, and forcing feed material on the screen surface jumps along with the screen box, the material which is less than sieve aperture will be discharged from the outlet after continuous rolling and jumping movement, then screening operations complete.

 

Gyratory screen is a new type of high efficiency swing type linear screening equipment ,and also called square swing sieve, it can completely solve the screening accuracy and processing output contradiction of general vibration screening machine, see the following characteristics:
1.Reasonable design, mature technology, easy installation and maintenance, wide application scope;
2.High screening efficiency , precision and processing capacity;
3.Unique design, convenient screen mesh replacing, high utilization rate, long service life;
4.Good screen mesh self-cleaning effect is good, low noise;
5.Good sealing effect, energy saving and environmental protection.

Besides, gyratory screen can be used in chemical, metallurgy, ceramics, non-ferrous metals, food, abrasive, mining and other industries in the accurate screening and grading process. Specific application materials, for example, chemical industry: chemical fertilizer, resin, melamine, soda ash ; Food industry :starch, salt, sugar, milk powder and other; metallurgy, non non-ferrous metals, nonferrous metal, magnetic materials.

Dewatering Screen for coal industry

Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.

Working principle:

      To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
      When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.

Features:
   1. Low noise, easy to maintain
   2. Large capacity
   3. High screening efficiency
   4. Light weight, easy to disassemble and replace
   5. Stable structure and strong exciting force

Advantage:

   1.Stable structure with strong exciting force
   2.High screening efficiency and low noise pollution created
   3.Durable and easy maintenance
   4.Materials that stuck at the screening mesh can easily remove
   5.Low energy consumption
   6.Large handling capacity.
   7.Light weight, easy to disassemble and replace

Application:
Dewatering screen is widely used in coal industry, ore industry, electricity industry metallurgy industry, mining industry etc.
