WHY A MANUFACTURER MATTERS Plates, cloth, presses and screw presses are produced in our own workshops rather than bought in. We quote non-standard plate sizes, supply replacement plates and cloth for other manufacturers' presses, and support a machine for its whole working life. In-house quality inspection centre and more than 30 R&D engineers. HOW WE SIZE A JOB Send us the slurry data - daily volume, dry solids content, particle size, operating temperature and pH, and your target cake moisture - and we return a sized proposal covering machine selection (filter press or screw press), filter area, plate type, cloth selection, feed pump and cycle time. WHERE OUR EQUIPMENT RUNS Municipal sewage sludge dewatering; mining, mineral concentrate and tailings dry stacking; coal slurry; stone, granite and marble cutting slurry; electroplating and surface finishing effluent; chemical and petrochemical; oil and gas; pharmaceutical; food, beverage and brewery; ceramics and kaolin; textile dyeing; pulp and paper; metallurgy and steel; power and new energy; sand and aggregate washing. We export to more than 40 countries. Contact: Lin Cong, Deputy General Manager - lincong@czsenjie.com - +86 181 5173 1332 (WhatsApp same number) - https://czsenjehb.com
