Pertanyaan yang sering diajukan tentang filter press

A chamber press uses recessed plates and relies on feed pressure alone, giving 25–45 % cake moisture at the lowest cost. A membrane press adds an inflatable diaphragm that squeezes the cake to 15–30 % moisture in a shorter cycle. A plate-and-frame press uses alternating plates and frames, is easiest to wash and unload, and suits food, oil and fine chemical clarification.

For tailings and concentrate, a membrane filter press is usually the right choice: it reaches 15–25 % cake moisture so the cake can be dry-stacked or trucked, and the shorter cycle means fewer plates for the same tonnage. A chamber press works when moisture of 30 % or more is acceptable and capital cost matters most.

Municipal and industrial sludge is normally handled by a fully automatic chamber or membrane filter press with PLC control, automatic plate shifting and cloth washing. Chamber presses reach 60–75 % solids; membrane presses reach 70–85 % solids and cut disposal cost.

Start from dry solids per day, slurry concentration and target cycles per day. Cake volume per cycle = daily dry solids ÷ cycles ÷ cake density ÷ (1 − cake moisture). Divide by chamber volume per plate to get plate count, then check filtration area against filtration rate. Send us a slurry sample or lab data and we return a sizing sheet within 24 hours.

Yes. Plate size, plate count, chamber depth, membrane or recessed plates, cloth material and micron rating, feed pump type, drip trays, cake conveyors and full PLC automation are all specified per project.

Yes. We run bench filter press tests on your sample to measure filtration rate, cake moisture and cloth blinding. The report is used to size the industrial press and choose the cloth.

In 2026 a Chinese-made chamber filter press typically runs from about USD 8,000 for a small 630 mm unit to USD 60,000–150,000 for a 1500–2000 mm fully automatic membrane press. Price is driven by plate size, plate count, membrane vs chamber, automation level and material of construction.

Three things: filtration area (plate size × plate count), membrane vs chamber plates, and automation (manual, semi-automatic or PLC with auto plate shifter and cloth wash). Stainless or special cloth adds a smaller premium.

Standard chamber and membrane presses ship in 25–45 days after deposit; large or fully automatic units take 45–60 days. Sea freight from Shanghai is roughly 7–15 days to Southeast Asia, 15–25 days to India and the Middle East, 25–40 days to Africa and Latin America.

We quote EXW, FOB Shanghai or CIF to your port. DDP is possible for some countries through our freight partners. Tell us your port and we include freight and insurance in the quotation.

Standard terms are 30 % T/T deposit and 70 % before shipment. Irrevocable L/C at sight is accepted for larger orders. Invoices are issued by Prosper International Trading (Changzhou) Co., Ltd., our export entity.

Typically 15–30 % depending on particle size and slurry chemistry. Fine mineral concentrates reach 12–18 %; municipal sludge reaches 25–30 % solids-equivalent.

A chamber press cycle is usually 45–120 minutes; a membrane press cycle is 20–60 minutes because squeezing replaces the slow end of filtration. Cycle time depends on slurry concentration, cloth permeability and feed pump curve.

The press itself only uses the hydraulic power pack (typically 2.2–7.5 kW) during closing and plate shifting. The feed pump is the main consumer, 5–45 kW depending on size. Energy per tonne of dry solids is generally 3–10 kWh.

Air-operated diaphragm (AODD) pumps for small presses and abrasive slurry; slurry pumps with VFD for mining; progressing cavity screw pumps for sludge; ceramic plunger pumps for high-pressure membrane presses.

Polypropylene (PP) is the default for most mineral and chemical slurries. Polyester (PET) for higher temperature, polyamide (nylon) for abrasion, PTFE-coated for sticky cakes. Micron rating is chosen from lab tests; 5–100 µm covers most applications.

Yes. For automatic presses we send an engineer for installation, commissioning and operator training; travel costs are quoted separately. For manual and semi-automatic units most customers install with our video guide and remote support over WhatsApp.

The frame, hydraulic system and plates are covered for 12 months from commissioning (18 months from shipment). Filter cloth is a consumable and is not covered.

Contact our service team on WhatsApp (+86 181 5173 1332) or email lincong@czsenjie.com. Emergency support is available 24/7; standard support 8:00–21:00 Beijing time.

Typically every 1,500–3,000 cycles, or 3–12 months, depending on slurry abrasiveness and washing practice. Sudden loss of filtrate clarity or cake sticking usually means it is time to change cloth.

Reinforced PP plates last 5–10 years in normal service. Membrane plates last 3–5 years; the membrane itself may be replaced separately.

Yes. We manufacture filter cloth and PP plates to drawings or samples for most European, Indian and Chinese presses. Send the plate size, thickness and feed hole position.

Yes. Custom filter cloth for filter presses, belt presses and centrifuges is a core product. Minimum order is one set for a press.

CE certificate, ISO 9001 factory certificate, material test reports for plates and cloth, hydraulic test report, packing list and commercial invoice. Certificate of origin and other customs documents are provided on request.

Presses up to 1250 mm ship assembled in a 20 ft or 40 ft container on a steel skid with plastic wrap. Larger presses ship as frame plus boxed plates. All packing is fumigation-free plywood or steel.

We have shipped to more than 40 countries, mainly Vietnam, Indonesia, Malaysia, Thailand, the Philippines, India, Pakistan, Nigeria, South Africa, Chile, Peru and the Middle East.

Yes. The factory is in Changzhou National High-tech Industrial Development Zone, about 1 hour from Shanghai by high-speed rail. We can also arrange a live video factory tour.
