SET OF HYDRAULIC CYCLONES OF FINE ORE SUSPENSION FRACTIONATION Russian patent published in 2012 - IPC B04C7/00 C22B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to ore suspension separation. Fine complex ore suspension separation system comprises set of hydraulic cyclones, pulp distributor and one to six hydraulic cyclones with total output of 12 to 70 m³/h mounted on frame support. Every hydraulic cyclone is made up of cone housing with intake chamber, feed and discharge branch pipes, and sand bed integrated along the bottom with beds of other cyclones, and furnished with inner lining from wear proof material. Cone section of hydraulic cyclone is formed by variable-thickness lining. Housing cylindrical section ID is 3.5-5.0 times larger than discharge branch pipe outlet diameter while branch pipe cross-section area makes 0.6-1.0 of feed branch pipe cross-section area and is 6-25 times larger than that of sand bed outlet channel at inner taper angle of housing bottom of 14-18 degrees.

EFFECT: higher efficiency and quality of separation, stable and reliable operation.
