Search for an optimal jigging machine operating regime. [Magnitogorsk Integrated Iron and Steel Works-USSR]
An investigation of the operation of jigging machines for cleaning of fine coal was conducted under industrial conditions. Continuous monitoring was accomplished by the express analysis method in an aqueous solution of zinc chloride with the ash of the products determined. The capacity of the machines varied from 70 to 210 tons/h, the pulsator rotation speed from 41 to 97 rpm, and the air pressure from 12.7 to 13.7 kPa. The investigation was conducted by a passive experiment method. The tests showed that a change in the load from 170 to 190 tons/h with a simultaneous change in the content in the byproduct from 6.5 to 15% caused a decrease in the oscillation frequency from 80 to 65 rpm and a slight reduction in the cleaning efficiency (from 35 to 33.8%). With annual control the jigging efficiency averaged 23%.
