Thickening - SpringerLinkThickener Torque -Rakes & Drive

Dec 20, &#; The chapter analyzes thickening in-depth In an extensive introduction, the history of thickening is laid out from the Stone Age to the present, emphasizing people and institutions that have been important actors The chapter then reviews the thickeners used in the mining-mineral industryA little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque Each rake arm is higher at its far end than it is where it joins the drive shaft This is designed this way to give the bed a slope towards the centre of the thickener.

Coal preparation plant - WikipediaHow a Thickener Works - Mineral Processing & Metallurgy

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or shipsThe standard construction of Dorr thickener mechanisms is of iron and steel The tanks are usually made of steel or wood for medium-sized machines, but in the larger sizes they are often constructed of concrete or earth or a combination of these materials.
