The belt filter press is a highly efficient solid-liquid separation equipment based on the principles of chemical flocculation contact filtration and mechanical extrusion. It is gaining increasingly widespread recognition across various industries due to its series of advantages, including simple process flow, high automation, continuous operation, easy control and operation, and adjustable working procedures. Furthermore, when used in conjunction with a gravity thickener, it can eliminate the need for a thickening tank for the treated material, thereby saving construction costs to some extent. Currently, this equipment is widely used for sludge dewatering in industries such as municipal sewage, textile dyeing and printing, electroplating, papermaking, leather, brewing, food processing, coal washing, petrochemicals, chemicals, metallurgy, pharmaceuticals, and ceramics. It is also suitable for solid-liquid separation or liquid leaching processes in industrial production.

Operating Principle:
Preparation stage.
After flocculation, sludge will be distributed to the filter cloth. Much water will separate with floc under gravity. The efficiency of the preparation depend on filter cloth, sludge and flocculation.
Wedge pre-press dewatering stage
After gravitational dewatering, flow ability will be much lower but still cannot be pressed by roller. Wedge pre-press dewatering will remove surface water and make the flow ability to a certain condition which ensure sludge will be pressed properly.
Squeezing dewatering stage
Then sludge will be conveyed to squeezing roller system. The roller’s size gradually be smaller meaning while, the outside pressure being larger.
Why Choose Our Belt Filter Press?
Lower Total Operating Costs
Reduced Chemical Use: Advanced flocculation systems and optimized dewatering paths significantly cut down on flocculant (PAM) consumption.
Savings on Water & Power: Efficient backwash systems and scientific roller press design lower water usage for cleaning and reduce drive power consumption.
Lower Labor Costs: High automation (auto-tracking, tensioning, cake discharge) and durable design greatly decrease daily operational and maintenance demands.
More Stable and Reliable Performance
Robust & Durable: The core structure uses heavy-duty design and high-strength materials (e.g., stainless steel, rubber-coated rollers), ensuring long-term stable operation in harsh conditions with low failure rates.
Intelligent Self-Protection: Integrated pneumatic auto-tracking, infrared safety guards, and emergency stop systems effectively prevent belt misalignment, damage, and personnel accidents, ensuring safe and continuous production.
