FILTRATION MACHINE- Continuous Filters
In beneficiation plant , filtration machine can be divided into three modes: continuous, batch and semicontinuous, and clarifying. Each of these modes can be further subdivided. The discussion that follows is limited to those units with significant application in mineral and coal processing . Continuous Filters Continuous filter s may be divided into those forming their filter cake against gravity and those forming their filter cake with gravity. Filters Forming Cake Against Gravity. Disk and drum filters all form cake against gravity. The latter can be further divided into scraper discharge, roller discharge, and continuous-belt drum filters. A disk-type filter contains a series of individual disks mounted on a center barrel. The barrel is held in trunion bearings mounted on either end of the filter tank. The disks are partially submerged in the feed slurry to a standard apparent submergence of about 35%. A higher submergence would require stuffing boxes around the center b...
