What is a filter plate?

In the stone industry, the filter plates of filter presses are extremely crucial. The core function is solid-liquid separation. The slurry produced during stone processing contains stone powder, fragments, water, etc. With its precise pore structure and suitable filter media, the filter plate allows water and dissolved substances to pass through while retaining solid impurities.

The filter plate can construct a sealed and pressurized chamber. Multiple filter plates are assembled into compartments, which can withstand high pressure and have a tight seal to prevent the leakage of slurry and filtrate, accelerating solid-liquid separation. This is of great significance in the stone industry as it can increase the processing capacity and separation quality.

Polypropylene filter plate (PP) is mostly used in terms of material. It has strong chemical resistance, can resist chemicals such as cutting oil in the slurry, is durable, and is lightweight and easy to operate. Its strength and rigidity are sufficient to cope with the filtration pressure.

During use, regular maintenance is essential. It is necessary to inspect and clean the filter plates to prevent the clogging of pores and media. High-pressure water jets and chemical cleaners can be combined to remove dirt. At the same time, pay attention to the condition of seals and gaskets and replace them in time if there is any damage to avoid affecting filtration efficiency and causing environmental and operational problems. In conclusion, the filter plate plays a decisive role in the efficient and stable operation of filter presses in the stone industry.
