Applications
Mining: Expertly crafted for the dewatering of ores and effective management of tailings.
Chemical Engineering: Perfect for the precise filtration of chemical raw materials and by-products.
Wastewater Treatment: Efficiently handles sludge dewatering and ensures thorough solid-liquid separation.
Food Industry: Ideal for the meticulous filtration treatment of beverages such as juices and wines.
Other Industries: Exceptional for high-temperature wax removal, meeting diverse industrial needs.
Work Principle
The operational principle of our cast iron pressure filter is brilliantly simple yet highly effective: the liquid slated for treatment is introduced between the filter plates and cloth. Through applied pressure, the liquid traverses the filter cloth, leaving behind solid particles that form a convenient filter cake. Conclude the process effortlessly with mechanical unloading post-filtration.
Maintenance and Care
Regular Inspection: Prioritize regular inspection to ensure all connecting parts and seals remain intact, effectively preventing any potential water leakage.
Cleaning: Maintain peak performance by promptly washing the filter cloth and plates post-use to eliminate any residue build-up.
Lubrication: Keep your equipment in top condition with regular lubrication of moving components, ensuring seamless and smooth operation.
Summary
In summary, the cast iron pressure filter, with its robust build and superior performance, has solidified its place as an essential asset for industrial solid-liquid separation. Adhering to proper usage and maintenance protocols will not only heighten production efficiency but also drive down operating costs significantly.
