The cast iron press filter stands as a pinnacle of efficiency in solid-liquid separation technology. Esteemed across diverse industries, including chemical engineering, mining, food processing, and wastewater treatment, this equipment's core lies in its cast iron construction, guaranteeing exceptional durability and unwavering stability.
Product Features
Durability and Strength: Engineered from cast iron, this structure confidently handles operations under intense pressure and high-temperature environments, ensuring unwavering reliability.
Exceptional Filtration Efficiency: Its cutting-edge design revolutionizes the speed and effectiveness of solid-liquid separation.
Superior Corrosion Resistance: Undergoes specialized treatment to proficiently manage exposure to various chemical media.
Effortless Maintenance: Designed for easy disassembly and cleaning, it drastically reduces downtime and maintenance efforts.
Applications
Mining: Expertly handles ore dewatering and tailings management with unparalleled efficiency.
Chemical Engineering: Masterfully filters chemical raw materials and by-products, ensuring purity and precision.

Food Industry: Perfectly suited for the filtration of juices, wines, and more, enhancing product quality.
Other Industries: Excels in high-temperature wax removal applications.
Work Principle
The cast iron pressure filter begins by introducing the liquid between meticulously engineered filter plates and cloth. Under pressure, liquid is seamlessly driven through the filter cloth, leaving solid particles to form a filter cake. Upon completion of filtration, mechanical unloading is effortlessly executed.
Maintenance and Care
Routine Inspection: Diligently ensure all connecting parts and seals are in optimal condition to prevent any leakage.
Thorough Cleaning: Promptly clean filter cloth and plates post-use to eliminate residue build-up.
Lubrication: Consistently lubricate moving components to guarantee smooth and efficient operation.
Summary
Boasting a robust design and superior performance capabilities, the cast iron pressure filter is a vital asset in industrial solid-liquid separation. Implementing proper usage and diligent maintenance elevates production efficiency and significantly curtails operating costs.
