Horizontal screw centrifuge is a kind of mechanical equipment for continuous separation of suspension containing density difference by centrifugal settling principle. Our company's centrifuge can clarify, dehydrate or separate suspensions containing solid particles of 0.002-3mm in diameter and 0.5-40% in concentration range. According to material features, it can be divided into LW two-phase horizontal decanter centrifuge and LWS three-phase horizontal decanter centrifuge


It can be used to separate different materials under different working conditions, and is widely used in pharmaceutical, food, chemical, environmental protection and other industries.

Working Princple

working principle of horizontal screw centrifuge


  1. All the parts that may contact the material are made of high-quality high-strength austenitic stainless steel or duplex stainless steel, which have sufficient strength and excellent corrosion resistance, and have been stress eliminated for many times.

  2. The drum BODy has large aspect ratio, high rotational speed and a variety of angle drum cone structure.

  3. The screw pusher is made by special molding method, with small screw pitch error and small blade deformation. The screw pushing surface adopts special anti-wear measures, spraying and welding cemented carbide or inlaying cemented carbide wear-resistant sheets, so it is anti-corrosion and wear-resistant and has long service life.

  4. The differential system has reliable performance. This series of centrifuge differential generally adopts planetary gear or cycloidal pinwheel differential. According to the needs, it can also be equipped with full hydraulic differential system. Mechanical differential generally adopts domestic well-known brand, hydraulic differential system adopts imported brand. The differential has high manufacturing accuracy, good performance and reliable operation.

  5. The horizontal decanter centrifuge with BD baffle, has deepened the liquid pool. It can concentrate and dehydrate various primary sedimentation sludge and residual activated sludge in different proportions, and efficiently separate some hard-to-separate materials.

  6. The main motor and the auxiliary motor are controlled by frequency converter to realize stepless speed regulation, which has wide adaptability to materials and simple debugging.

  7. The centrifuge adopts reasonable tolerance control and advanced processing technology. The centrifuge uses precision dynamic balancing of double rotor and adopts imported SKF bearings. Therefore, the vibration of both ends of the centrifuge bearings is kept within 2.5mm/s when the centrifuge leaves the factory (national standard excellent grade).
