Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
The spiral classifier such as the Akins classifier consists of a semi cylindrical trough inclined to the horizontal. The trough is provided with a slow rotating spiral conveyor and a liquid overflow at the lower end. The spiral conveyor moves the solids which settle to the bottom upward toward the top of the trough.
The Spiral Classifier is available with spiral diameters up to 120. These classifiers are built in three models with 100%, 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. The spiral classifier is one of the size classifying equipment for the mining industry. It is a kind of equipment for mineral classification based on the principle that the specific gravity of solid particles is different and the speed of precipitation in the liquid is ...
EIMCO K.C.P. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are a partially drained fraction containing the coarse material and a fine fraction along with the remaining portion of the liquid medium .
