Description

Technical Field

[0002] Controlling the feed flow is very important in the operation of a centrifuge, which directly affects the separation effect and operation efficiency of the centrifuge. First of all, controlling the feed flow can help optimize the separation process of materials. In a tubular centrifuge, the control of the feed flow is based on the main characteristics of the materials and process conditions. By adjusting the feed pressure and speed, the output can be controlled by increasing or decreasing the intake pressure when the nozzle diameter is fixed. Under the same separation factor, the smaller the flow rate, the smaller the centrifugal force output by the centrifuge, and the better the separation effect of the materials. This means that by precisely controlling the feed flow, the materials can be better separated, and the separation efficiency and purity can be improved.
