Product structure
When the drum runs on a full speed driven by the main motor and transmission belt the suspension will be led to the product distributing play through feeding pipeline continuously. When the suspension will be distributed evenly on the filter net on the inner first-rate drum.
Most of the liquid phase will be thrown out through the fitter net and the filter holes on the drum wall and then drained outside through liquid outlet.The solid will be intercepted on the first-grade drum and form a cake ring While the drums of the two grad es are revolving together at a same speed the drum of the first grade will move reciprocate continuously in piston by the pushing of the pistons then the pushing plate will be able to push out the filter cake on the drum of the first grade. in the next step the filter cake will be pushed into the drum of the second grade to further separate and form a new filter cake Then the outer edge of the first-grade drum will push the new filter cake out of the second-grade drum continuously. The filtering and washing liquid can be drained out separately if necessary

Application field
It is suitable for the separation of suspension with solid particle size greater than 01mm and density greater than 30%. It can be used in chemical and food industry to produce sodium chloride,ammonium fluoride,ammonium bicarbonate, sodium sulfate,urea,polyethylene polystyrene, oxalate, nitrate and so on.
Two-stage Pusher Centrifuge is a kind of perforated basket centrifuge, both continuous and effective.The machine can be used to continuously dewater and wash the slurry with crystal and fiber bigger than 50um,so far,it has succeeded in separating more than 200 different kinds of products,such as sodium salt, ammonium salt, sylvine tripolyamide , PVC,EPS,etc.
