Decanter centrifuge LW450
Structures and properties:
This machine is horizontal spiral discharging settling centrifuge, the main machine has a column-cone bowl, spiral stoker, differential system, bearing seat, base, cover, main motor,vice motor, and electric control chamber. With the high speed rotating of bowl, form strong centrifugal force, making the sludge dehydrate continuously in 24 hours a day.
The main motor through the triangle belt make the bowl rotating, through the planetary gear differential, make the vice motor and spiral differential speed different, realize sludge dewatering and pushing material function, That means differential rotating speed control and torque control. because containing solid rate of sludge may have wave motion, by differential speed control system is the guarantee for speed stability, achieve solid content in sludge is constant, the constant torque control make decanter load in a stable state, the separation effect and flocculation is the best state, so as to ensure the safe operation of the centrifuge.
This machine has good seal performance (guarantee without material leak in the process of operation), sludge dewatering work in full seal state, makes the environment clean.
This machine adopts the most advanced international special structural design, especially the spiral stoker, make the sludge concentration dehydration integration characteristics. It has better performance than ordinary centrifuge, more high capacity, better separation effect, save energy and manual work.
