Problems solved by technology

In fact, the slurry agitator in the flotation machine cannot drive the movement of the steel balls in the grinding medium. Adding the grinding medium into the flotation machine will cause the loss of the stirring function of the flotation machine, so the grinding effect cannot be produced.
Therefore, in any case, the traditional flotation machine does not have the function of grinding

Abstract

A tower-type grinding floatation machine for grinding and hydrosizing ore at same time is composed of tower-type main body divided into upper floatation regino and lower grinding-hydrosizing region, screw stirrer, and drive mechanism. Said lower grindnig-hydrosizing region contains screw stirrer and grinding medium. Its advantages are multiple function, simple structure, and high recovery yield.

Description

Technical field: [0001] The invention relates to a mineral enrichment equipment, in particular to a tower type (vertical) grinding and flotation machine capable of simultaneously performing flotation operations during the grinding process. Background technique: [0002] Grinding and flotation operations are important mineral enrichment processes. Now 90-95% of the world's ore needs to be enriched before it can be used by other industries. One of the mineral enrichment methods used is the flotation method, which is divided into forward flotation and reverse flotation. The forward flotation is for floating target minerals, and the reverse flotation is for floating and discarding tailings. No matter which method is used, the buoyant minerals (stones) containing the purpose enrichment are firstly ground to a certain fineness by a grinding machine, and then enter the flotation process. Since most of the traditionally used grinding machines are horizontal ball mills, sub-grid ty...
