The performance of Screen Bowl Centrifuges has been continuously modified and improved to dewater not only coarser coals, but also today's variety of ultrafine material. Actual test comparisons with alternative methods show the Screen Bowl Centrifuge to be most cost effective and efficient when all factors are considered.
WhatsApp: +86 18221755073In screen scroll centrifuges and decanters, the differential speed of the solids conveying screw to the bowl is also critical. It determines the residence time of the solids in the centrifuge and therefore the separation efficiency. The correct differential speed for your separation task is determined by selecting the right gear.
