For designing the pool area of a classifier, the concept of areal efficiency is necessary. Also, it is necessary to estimate the settling forces, the size of the overflow particles, the volume flow rate of the overflow or underflow stream and the settling rate of the heavier particles. The settling rate in turn depends on the shape of the particles and any disturbance in the pool.

A = pool area. ν T = terminal velocity (m/s) For spiral classifiers, the overflow solids capacity may be given by (13.22) Q MS (O) = n k 2 k 3 (3.92 D 2 + 0.67 D) for low weir pools (13.23) and QMS (O) = n k 2 k 3 (3.12 D 2 + 0.42 D) for high weir pools where. Q MS(O) = overflow solids capacity (t/h) n = the number of spirals
The Spiral Classifier is available with spiral diameters up to 120". These classifiers are built in three models with , 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. All sizes and models are available with single-, double- or triple-pitch spirals. The Spiral Classifier offers the greatest sand raking capacity of any classifier available ...
Because users' needs vary so greatly, the Classifier is available in a wide range of spiral diameters and pitches, tank shapes and lengths allowing exact compliance with each user's classification requirements. Spiral diameters (0.3 m to 2.25 m): Important in establishing a correct balance between overflow and raking capacity.
Meanwhile, for the classification process, the cut sizes could be optimized by determining the pool area for the spiral classifier and the inlet, overflow, underflow diameters, and pulp densities for the hydrocyclone. The entire grinding/classification process was analyzed based on the calculated particle size distributions and the mass ...

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the next stage in the process ...
In these classifiers the required pool area is balanced with the sand raking capacity of the spiral by the design of the tank. Heavy particles have time to settle at the bottom and the spiral conveyor moves the settled particles upwards along the floor of the trough. Spiral classifiers are used for close circuit grinding.
