Thickener sizing and the importance International Mining

Thickener performance parameters, such as underflow densities and overflow clarities, and the effect of feed variables such as rise rate and solids loading rate, can vary greatly for different thickener feeds. Even for the same types of application, thickener performance will vary at different sites due to factors such as particle size, the presence of clays and organic materials, water

Pulp, paste and putty thickeners and flocculants for high

High density or high compression thickeners (HDT) are designed to produce underflow rheological yield stress of up to 100 Pa. HDTs accomplish this effect by using deeper mud bed heights up to circa 2 meters and above to enhance compression and a rake mechanism with pickets to create dewatering channels in the consolidating bed. The mud level hence tank wall height is greater than high rate
