Performance Characteristics of the Impurity Removal Machine
The impurity removal machine is a new type of centrifuge developed on the basis of the original LW series horizontal decanter centrifuges. It has a smaller separation factor compared to the similar LW series horizontal decanter centrifuges, but its production capacity, separation efficiency, and the moisture content of the discharged slag have all been significantly improved. This machine has the following characteristics:
1. Suitable for the primary solid - liquid separation of suspensions in the gutter oil industry of kitchen waste.
2. High degree of automation: This machine features continuous feeding and continuous discharging. Under the action of centrifugal force, solid particles are continuously pushed towards one end of the drum by the screw and discharged. The clarified liquid phase flows out through the mesh holes on the circumference of the drum and is discharged from under the casing, thus achieving continuous automatic operation.
3. Compact structure, small footprint, and convenient installation and maintenance.
4. Easy to adjust: Thanks to the adoption of an advanced variable - frequency speed governor, this machine has the advantages of low energy consumption and steplessly adjustable working speed compared with similar products.
5. All parts of this machine in contact with materials are made of stainless steel.

Principle of the Impurity Removal Machine
The working principle of this machine is as follows: The machine gradually increases its speed through the frequency converter. Driven by the pulley, the drum rotates at a certain speed to generate centrifugal force for the discharging function. After the machine speed stabilizes, the suspension enters the mesh holes of the drum through the head tank, flow control valve, and feed pipe. Under the action of a strong centrifugal force field, the solid particles with a higher specific gravity are thrown onto the settling wall and quickly deposit on the inner wall of the drum mesh holes. The rotating spiral blades generate a driving force, and the sediment is continuously pushed towards one end and discharged from the slag outlet through the solid - phase collection casing. The separated clear liquid flows out through the mesh holes of the drum and is discharged by the liquid - phase collection casing. The separated filtrate is discharged from the filtrate collection chamber, forming a continuous automatic separation process.

Structure
The impurity removal machine consists of components such as a drum, screw conveyor, main bearing, chassis, liquid - solid phase collection chamber, upper cover, motor transmission device, and frequency converter.
