Product Details

Introduction

The special filter press for coal washing is an important equipment for the coal preparation plant to realize the recycling and washing closed cycle in the coal sludge plant.

The filter press has many unique features in design: firstly adopt chain drive to close, then use five cylinders to compact, which greatly shortens the length of the cylinder, which is beneficial to the enlargement of the equipment. The filtrate adopts the open and close flow discharge mode to improve the filtration speed; based on the liquid level meter, can adapt to different concentrations of coal slurry water, using PLC to control, can automatically complete the feeding,  filtering, unloading, reduce the labor intensity of workers, and the filter cake moisture can be adjustments within a certain range according to needs.

The special filter press for washing coal has the characteristics of high technical content, fully automatic operation, safe and reliable equipment, fast adaptability of high pressure filter material, low moisture content of filter cake, strong production capacity and good economic effect. The special filter press for coal washing is mainly used for dewatering of clean coal, tail coal and primary slime, which has high promotion and application value.

Therefore, the slime filter press is the first choice for the special filter press of the coal washing plant.
