Ultra-high-pressure press filter

High feed pressure and large processing capacity: The maximum feed pressure reaches 1.5 MPa, twice that of conventional filter presses, enabling a faster feeding process and producing filter cakes up to 70 mm thick (actual cake thickness depends on the characteristics of the coal slurry). Taking an 800 m² filter press as an example, a single cycle can be completed in 30 minutes, with a per‑cycle output of up to 25 tonnes of coal slurry and an hourly throughput of up to 50 tonnes.

The filter plates are made of high‑strength magnesium‑aluminum alloy, featuring a lightweight design that keeps the overall machine weight low. They offer excellent mechanical strength and toughness, with superior pressure‑bearing capacity. The filter plates have a service life of 10 years!

Elastic, compressible filter plate frame: Made from high-performance elastomers, it offers robust support, excellent sealing, prevents material leakage, and ensures high safety. Direct hydraulic pressing, combined with the frame’s superior resilience, delivers higher pressure and a greater compression ratio, resulting in improved dewatering performance. The maximum pressing pressure can reach 10 MPa—eight times that of conventional filter presses—while shortening the pressing cycle and eliminating the need for water‑filling and pressurization steps. Consequently, the moisture content of the filter cake is reduced by an additional 10%–15% compared to traditional membrane filter presses.

The filter plate and filter cloth are joined in a flat configuration, with the filter cloth mounted flush within the frame, ensuring complete cake removal with no residue. The filter cloth has a service life of 6 months!

Intelligent Unattended Operation: Utilizing a PLC‑based, fully automated control system along with auxiliary sensing technologies such as laser ranging, industrial cameras, flow monitoring, and pressure detection, the process automatically manages every stage—plywood assembly, material feeding, pressing, and discharge—without any manual intervention. This significantly boosts operational efficiency, reduces worker fatigue, and minimizes the risk of human‑error‑related accidents, truly enabling unattended operation.
