Feed slurry enters the feed well, which is usually located in the centre of the thickener, through a pipe or launder suspended from the bridge. To avoid excess velocity, an open launder normally has a slope no greater than 2/100.
20171030&ensp·&enspThe separation of solids from a liquid by gravity sedimentation has traces to the early days of civilization. The normal practice at those times was to use jars or pits mainly for the clarification of extracted liquids such as wine or olive oil from contaminating insoluble matter.

Why process at all? Of course, the answer is ultimately feed efficiency, producing the most milk, eggs, meat or fiber at the lowest possible cost.
2012710&ensp·&ensp55 known as the distribution function [45, 46]) describes the distribution of fragment sizes obtained after a breakage of particles of size xj.Thus, b1j, b2j,, bnj are the mass fractions of particles in size classes 1, 2,, n after a breakage of particles in size class j. The mechanism of breakage is illustrated in  by a diagram shown in Fig. 3.
2020516&ensp·&enspUnder normal conditions our EXAMPLE mill feed thickener rake drive will operate with the gear mechanism lowered, regardless of grinding or leaching operations. Operating lights on the mill control panel indicate whether the rakes are fully lifted, fully lowered, moving up or down, turning or stopped. An exact intermediate rake position is not indicated on the panel however, close scrutiny of
2020518&ensp·&enspKnowing how to size a thickener and determine the capacity required to handle a predetermined tonnage of a certain pulp, by overflowing a clear solution and obtaining the desired pulp density of thickener discharge, depends upon the settling rate of that particular pulp. The settling rate of any pulp is easily determined by simple laboratory tests such as outlined below: Laboratory Test
