Disintegration of ores and minerals in the scrubbing tank

Structurally, an attrition machine is a tank (chamber) with a vertically installed shaft inside, equipped with multiple tiers of blades.

The blades are positioned at opposing angles, and as the shaft rotates around its axis, they create counterflows of the slurry within the tank.

The disintegration process in the attrition machine is based on the friction of fine solid particles within a high-density slurry.

During intensive mixing, mechanical destruction of agglomerates and low-strength grains occurs.

Oxidative films on the surface of solid particles are removed, and the grains of minerals are cleaned and exposed.

The attrition machine consists of a series of chambers arranged in sequence, with the number of chambers ensuring the required volumetric capacity and the necessary degree of mineral liberation.

Designed for the following technological tasks:

– сleaning the surface of mineral grains to activate the surface before flotation, magnetic, or optical separation processes;
– disintegration of fine-dispersed materials for further classification on concentration tables or spiral separators;
– lime slaking during the production of lime milk;
– conducting chemical and physico-chemical reactions, as well as reagent dissolution.

Application experience:

– beneficiation of quartz and polymetallic ores;
– extraction of the coal component from ash and slag storage facilities of thermal power plants.
