Introduction
Horizontal decander centrifuge is a mechanical equipment that utilizes the principle of centrifugal settling to continuously separate materials with density differences in suspension.
The equipment has a compact structure, continuous operation, stable operation, strong adaptability to separated materials, large production capacity, and convenient maintenance. The centrifuge adopts dual frequency conversion drive, which is easy to operate and adjust operating parameters; In terms of energy conservation, when the auxiliary motor is working, it can also play a power generation function. By using the DC line of the sub motor to compensate for the current generated by the auxiliary motor to the main motor, it has energy-saving benefits.
Product structure and operation principle
The basic principle is that the drum and the conveying screw rotate at a certain differential speed at high speed, and the material is continuously introduced into the spiral pushing inner cylinder through the feeding pipe. After acceleration, it enters the drum, and under the action of the centrifugal force field, the heavier solid phase deposits on the drum wall to form a sediment layer. The feeding screw feeder continuously pushes the deposited solid matter to the cone end of the drum, dehydrates it in the drying area, and is discharged from the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which continuously overflows from the overflow port at the large end of the drum and is discharged from the machine through the liquid outlet. This machine continuously completes processes such as feeding, settling, separation, dehydration, and unloading under full speed operation.

Product structure
Adopt planet-gear differentia for the machine, so the torque of pusher is large, use transducer driver for the differential motor, differential speed can be adjust stepless, and have a well adaptable for materials.
Inspection steps: stopping the machine and all power supply of electrical equipment has been cut off, open the machine upper cover, check the joint of drum cover and flange which in both two-side solid end and upper end cover of liquid end, inspect drum end cover. In addition, solid material plug holes of machine should be checked, double-check all the wear and tear, cracks, or corrosion components which can be seen, any parts was found need to be maintained and must be repaired before re-use, in addition to do above examinations, user should double-check the wear condition of screw conveyer and all outlet opening, any wear components must be repaired or replaced.
