This machine uses fluidized bed technology for the separation and hydraulic classification of slurred fines for the production of three classified products.
The two-step process permits the handling of slurries without pre-thickening. The coarse and heavy particles are separated in the coarse section. The discharge of coarser material out of the central hopper is automatically controlled by a density probe.
In the peripheral ring called the fine section, the separation of light particles from the fines and desliming takes place. Plarticles of a lower specific gravity than the fluidized bed will remain above the fluidized bed and will overflow with most of the process water to the overflow chute. It has the advantage of classifying, separating, thickening and desliming in one step. This machine is fully automatic with no moving parts and can take a feed of size < 4mm with throughput rates of up to 2000 tph.
