GP Tailings Dewatering Screen


GP series tailings dewatering screen is a kind of vibrating screen specially developed for dry discharge of metal tailings on the basis of high-frequency screen, combined with the characteristics of metal tailings, mainly used for dehydration of iron ore, copper ore, gold ore, aluminum ore and other tailings.

Working principle

GP series tailings dewatering screen is mainly composed of screen box, supporting device, electric frame, vibrator, universal transmission shaft, belt coupling, motor and other components.
Tailings dry sieve used for tailings dry row, filling tailings by feeding box evenly into the sieve into the mouth, with the first level at 45 degrees to install drain water sieve plate removal about 1/3 of the water, into the plane after the integration of a sieve plate and the tilt of the sieve plate, appear in the accumulation of material, the coal particles by gravity settling, began to form a thin filter, filter layer and prevent the remaining particles through the sieve, the filter layer gradually thickening.

Failed to thoroughly and form pool of water in the upper filter because the filter layer is thinner, water gradually under the strong movement gradually take off, because of the high frequency low amplitude vibration state, make form a filter layer of tailings is more and more dense, to the discharging mouth, material forming filter cake shape, the moisture in tailings in addition to the part from the screen surface removal, the rest due to capillary action on the bed surface, due to the screen surface installation, negative Angle from discharging mouth water not overflow, the integration of a surface water will flow to the pool.

Technical features

1. High working frequency, high vibration intensity, high solid recovery rate can be obtained when used for tailings dehydration.
2. Adopting the principle of self-synchronization, the motor drives the vibrator through the tire coupling, with simple structure and low working noise.
3. The side plate is connected with the beam with torsional shear high-strength bolts, and there is no welding seam, so as to avoid the side plate cracking caused by welding stress.
4. The screen surface adopts polyurethane elastic screen with high porosity and elasticity, which is conducive to dewatering.
