UNIT OF HYDROCYCLONES INCORPORATED WITH FINE ORE SUSPENSION SEPARATION SYSTEM Russian patent published in 2012 - IPC B04C7/00 C22B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to ore suspension separation, particularly, to hydrocyclone units used in fine ore suspension separation systems in mining, metallurgy, chemical industry, etc. Proposed system comprises unit of hydrocyclones, pulp distributor whereto connected are one to eight hydrocyclones with total capacity of 550 to 2600 m³/h of separated ore suspension. Unit hydrocyclones are mounted on common frame. Every hydrocyclone is shaped to tapered-cylinder housing with intake chamber, feed and discharge branch pipes, and sand bed integrated with those of other hydrocyclones and provided with inner lining of wear resistant material. Hydrocyclone housing cylindrical part ID is 2.9-3.6 times larger than that of discharge branch pipe while cross-section of the latter makes 1.27-1.89 of cross-section area of feed branch pipe and is 5.0-14.0 times larger than that of sand bed outlet channel at taper angle of hydrocyclone housing bottom of 16-22 degrees.

EFFECT: higher efficiency and quality of suspension separation, power savings, continuous operation.
