Problems solved by technology

Powder fillers in friction materials mainly include barite, wollastonite, vermiculite, talc, fluorite and other powder materials. The raw ore has been processed to remove some impurities, but not completely. The existing processing equipment is not online. A device for removing ore impurities. Therefore, a non-metallic ore ultra-fine grinding machine is required to remove non-metallic ore mineral impurities during processing, improve the purity of mineral powder, and stabilize the chemical and physical properties of mineral powder materials.

Abstract

The invention provides a nonmetallic ore pulverizing mill, which comprises two rows of grinding hammer heads; four strike posts, each of which being of a tetrahedron structure, are arranged between the two rows of the grinding hammer heads and are annularly and uniformly distributed on a mill shell; and slag discharge holes are formed in the second row of the grinding hammer heads and the lower part of a lining plate for synchronously discharging impurities as well as difficultly ground particles and foreign matters in ores, so that nonmetallic ore ultrafine pulverizing is realized, and the purity and the pulverizing efficiency of ore powder are improved.

Description

technical field [0001] The invention relates to a non-metallic ore grinding machine, in particular to grinding equipment required for preparing high-purity non-metallic ore powder fillers from high-stable friction materials, and belongs to the field of non-metallic ore powder processing equipment. Background technique [0002] The friction material belongs to the polymer composite material, and its main component is composed of three parts: polymer compound (binder), inorganic or organic fiber (reinforcing component) and non-metallic mineral powder filler (friction performance adjustment). It is formed by compression molding, heat treatment, and post-machining. It is mainly used for brakes and clutches of automobiles, motorcycles, and construction machinery. Non-metallic ore powder fillers account for 65-80% of friction materials, all of which are processed from natural non-metallic ores. Non-metallic ore powder fillers are an important part of high-stable friction materials...
