Horizontal spiral unloading settlement centrifuges (Decanters short) is the use of centrifugal sedimentation principle of separation suspension equipment. 
 Structural features: 
 1, drum and other main parts are corrosion resistant stainless steel; 
 2, the conveying screw with special anti-wearing, can be spray mounted carbide inserts carbide protective layer or film resistance; 
 3, large aspect ratio, high speed. Cone angle of the drum with a variety of structure; 
 4, the choice of heavy-duty, large transmission ratio of the cycloid, or hydraulic planetary gear differential; 
 5, differential speed and torque with the concentration of materials, flow changes automatically adjust the computer control system; 
 LW Series drilling horizontal spiral unloading settlement centrifuge (Decanting Centrifuge) for oil drilling characteristics, special equipment designed for solid-liquid separation can be running at full speed to complete feed, centrifugal sedimentation, discharge and other procedures , barite is mainly used for recycling, remove fine solids and reduce the solids content of drilling fluid to control the drilling fluid density, viscosity, and to ensure the performance of drilling fluids have an important role for fast drilling. 
 Centrifuge with a horizontal spiral centrifuge is not available on other than the advantages: 
 ① greater adaptability of materials that can separate a wide range of solid-phase particle size 0.005 - 2mm, uneven grain size in the solid phase also can be separated as usual. 
 ② can be automatic, continuous, long-term operation, maintenance, operation can be closed. 
 ③ single, large capacity, compact, small footprint, low operating costs.
