The mechanical impact type ultra-fine pulverizer is a super-fine pulverizing equipment selected by the domestic non-metal mining industry. The fineness of the product can generally reach d97=10μm, so-called 1250 mesh, and the high-performance fine classifier can produce d97. =5-7μm ultrafine powder product.

working principle:
Using a rotating body (rod, hammer, blade, etc.) that rotates at a high speed around a horizontal or vertical axis, the feedstock is subjected to a fierce impact, causing impact collision with the fixed body or the particles, and the particles are crushed by a strong force. The fine grinding equipment has two pulverizing effects of impact and friction, and also has a jet pulverizing action.

Performance characteristics:
Advantages: high pulverization efficiency, large pulverization ratio, easy adjustment of pulverization particle size, wide application range, simple structure, stable operation, small mechanical installation area, continuous and closed-circuit pulverization, suitable for smashing of medium and soft materials .

Disadvantages: There are wear and heat problems, and it is necessary to take appropriate measures for the crushing of heat-sensitive substances.

Scope of application:
It is applied to coal-based kaolin, calcite, marble, chalk, talc, pyrophyllite, mica, graphite, wollastonite, bentonite, diatomaceous earth and other non-metallic minerals with medium hardness and below, as well as superfine crushing of chemical raw materials, pigments and pesticides. machining.
