The SB type three legged centrifuge is a filtering sealed centrifuge
 that is manually operated for upper unloading and intermittent operation. The material is added to the drum from the upper part, and under the action of centrifugal force field, the liquid phase passes through the filter medium and is discharged outside the machine, while the solid phase is trapped in the drum. After shutdown, it is manually discharged from the upper part. This machine has the characteristics of smooth operation, simple operation, sufficient washing of filter residue, solid particles are not easily damaged, and feeding, washing, and dehydration are carried out in a closed state. Suitable for separating suspensions containing solid particles ≥ 0.01 millimeters. Solid particles can be in granular, crystalline, or fibrous forms, especially for filtering high viscosity, fine particle size, toxic, and flammable materials. Therefore, it is widely used in industries such as chemical, pharmaceutical, food, and light industry. At the same time, special specifications of centrifuges can be produced according to the needs of users.
