Where is your factory located?

Our manufacturing facility is directly located in Jing County, Hengshui City, Hebei Province, China.

How can I reduce the moisture content of filter cakes?

Key parameters for moisture reduction include: – Increasing feed pressure (adjustable range: 0.8–2.0 MPa) – Activating membrane squeeze (secondary compression reduces moisture by 5–10%). – Extending the air-blowing time via the PLC control system. – Optimizing mesh size (800–1,200 mesh is recommended for fine particles).

What is the maximum processing capacity of a filter press, and how is the model size determined?

The processing capacity of a JW filter press depends on the chamber volume, the number of filter plates, and the effective filtration area. We calculate capacity using the following formula: Processing Volume (m³) = Chamber Volume × Cycles per Hour × Operating Time. Selecting a model requires analyzing material properties (e.g., solids content and particle size distribution) and process requirements (e.g., open-discharge vs. closed-discharge design). Please contact our engineering team with your material specifications for a customized recommendation.

How do I select the right filter plate material (polypropylene, rubber, or stainless steel)?

– Polypropylene (PP) : Suitable for weak acids and alkalis (pH 1–12). Cost-effective. Temperature resistance up to 80°C. – Rubber : Ideal for abrasive slurries (e.g., mining tailings) due to its high wear resistance. – Stainless steel (304/316L) : Resistant to highly corrosive media (e.g., chlorides and organic acids) with a temperature tolerance of up to 150°C. JW provides material corrosion resistance test reports upon request for validation.

How can I prevent or address clogged or torn filter cloth? What is the typical replacement cycle?

The lifespan of filter cloth depends on the characteristics of the material (e.g., viscosity and particle sharpness) and cleaning frequency. We recommend the following practices: – Apply backflushing combined with ultrasonic cleaning to restore permeability. – Use dual-layer composite cloths (e.g., polypropylene and polyester) in high-abrasion environments. The standard replacement interval is 3–6 months. For enhanced anti-clogging performance, PTFE-coated filter cloths are available as an optional upgrade.
