The XINGAONAI Plate and Frame Filter Press is a batch-operated pressure-filtration machine designed for solid-liquid separation. It uses alternating filter plates and hollow frames, with filter cloth installed between each plate and frame. Slurry is pumped into the frames, liquid passes through the filter cloth, and solids accumulate inside the frames to form filter cakes.
The equipment is suitable for mineral concentrate filtration, tailings treatment, coal-slime dewatering, chemical slurry filtration, ceramic processing, kaolin production and industrial-sludge dewatering. The listed models provide filtration areas of 250, 500 and 800 m² for medium- and large-scale industrial applications.
The press can be configured with hydraulic plate closing and automatic plate shifting to reduce manual cake-discharge work. Filter-cloth material and permeability are selected according to slurry particle size, temperature, pH, chemical compatibility, required filtrate clarity and cake-release characteristics.
Actual filtration capacity and final cake moisture depend on the slurry solids concentration, particle-size distribution, viscosity, feed pressure, cake thickness, filter-cloth selection and filtration-cycle time. When a guaranteed throughput or moisture target is required, laboratory or pilot filtration testing is recommended.
