1. Supply Name: LW150*650-N Horizontal Screw Discharge Decanter Centrifuge

2. Description of horizontal screw discharge decanter centrifuge：

3. This machine is a counter-current horizontal screw discharge sedimentation centrifuge. The main machine is composed of a column-cone drum, a screw discharger, a differential system, a bearing seat, a machine base, a cover, a main and auxiliary motor and an electrical system. Its working principle is: the suspension enters the drum through the feeding pipe and the screw outlet, and under the action of the centrifugal force generated by the high-speed rotation, the solid particles with larger specific gravity are deposited on the inner wall of the drum, and move relative to the drum. The spiral blades continuously scrape the solid phase particles deposited on the inner wall of the drum and push them out of the slag discharge port, and the separated clear liquid flows out of the drum through the opening of the liquid layer regulating plate. The relative movement between the screw and the drum, that is, the differential speed is achieved through the differential, and its size is controlled by the auxiliary motor. The shell of the differential is connected with the drum, the output shaft is connected with the screw body, and the input shaft is connected with the auxiliary motor. The main motor drives the rotation of the drum and also drives the rotation of the differential housing, and the auxiliary motor controls the speed of the differential input shaft through the coupling of the coupling. The differential can transmit the torque to the screw according to a certain speed ratio, thus realizing the continuous separation process of the material by the centrifuge.

4. This machine adopts the most advanced special structure design in the world, and has the characteristics of better performance than ordinary centrifuges, larger processing capacity, better separation effect, energy saving, stability and reliability, and easy operation. This product has passed ISO9001: 2000 family quality system certification . The mechanical properties are higher than the standard of JB/T502-2004 "Spiral Settling Discharge Centrifuge".
