Press Filter

Advantages

The equipment has stable performance, high degree of automation, safety and reliability, easy operation, and can realize backwashing operations;

There are two types of box filter press and plate and frame filter press;

Chamber filter press: suitable for concentrate filtration, tailings filtration dry discharge operation, product particle size can reach -500 mesh;

Plate and frame filter press: suitable for gold, silver, copper, iron, zinc ore, rare earth and other powder ore dewatering, tailings dam treatment.

working principle

Chamber filter press takes filter cloth as the medium to separate solid and liquid. It is a separating machine with wide rang of particle size. The filter cloth spreads in a filter board surface, it is supported by the swelling groove of filter board, when the filter board is clamped, filter cloth turns to seal materials, and the cavity between every two filter board forms a separated filter room. During the filter processing, the materials come through the central opening into filter room, the filtrate flow by the feeding pressure, flow out of the filter board after converged. Chamber filter press can be divided into two types according to filtrate discharging ways: open channel flow and under channel flow.

Plate and frame press filter separate the solid from the liquid in filter form. It is a separating machine with wide rang of particle size. Materials come through the filter room that made up of filter board and filter frame. Under the pressure of feeding materials, the filtrate flow through the medium that made up of filter board and filter frame-fiber gap of the filter cloth, arriving at the pattern surface, flow out of the filter board after converged. The solid left in the filter frame forms filter cake. Plate and frame filter can be divided into two types according to filtrate discharging ways: open channel flow and under channel flow.

success case

Zimbabwe 700d/t gold beneficiation project

For the production drainage system of the 700d/t gold concentrator in Zimbabwe, Xinhai uses two parts of the box filter press and the concentrator to complete the drainage operation. It is used to realize the non-discharge of sewage for the dressing plant.
