Cotton Seed Delinting Cotton planting seeds are treated with sulfuric acid to remove the lint to enable metered planting. The slurry is thick and non-flowing and is conveyed to the pusher using a screw conveyor. The acid treatment makes the lint brittle, so that the seed can be easily delinted in a subsequent tumbling operation. This application shows that the pusher can be successfully used for non-crystalline products. A low speed design results in lower seed breakage, and the rugged design allows extended and reliable service in a seasonal application.
Any centrifugal device offers the distinct advantage of a quick and efficient separation.
Pushers, in particular, offer high throughput in a continuous fashion. Low moisture and high purity in discharged cake has made the pusher centrifuge an excellent choice for solid-liquid separation. Thousands of pushers have been sold in mineral and chemical processes for a wide variety of applications due to its high throughput capacity and reliability. Over time, the pusher centrifuge has proved to be an excellent choice to dewater a concentrated slurry of free draining particles. Design modifications have made the pusher centrifuge applicable to an even wider range of applications.
