Abstract

The combined hydraulic superfine crushing and grinding apparatus includes a crushing box and a material box. The crushing box is provided with high pressure nozzle, mixing cavity, accelerating tube and jet target, and has also baffle, curved guide target, curved guide body, sieve pore board, top board, etc to form one spoon shaped crushing space with grinding balls. The combined hydraulic superfine crushing and grinding apparatus combines the crushing, grinding, vibrating and other effects of high pressure water jet, has best utilization of the energy of high pressure water jet, and possesses features of simple structure, wide applicable range and continuous production.

Description

technical field [0001] The invention relates to a grinding and pulverizing device for materials, which is suitable for the preparation and sorting of powder and slurry, and in particular to a composite hydraulic ultra-fine grinding machine which utilizes the principle of high-pressure water jet pulverization combined with grinding, vibration and other pulverization principles. Crushing grinder. Background technique [0002] The existing ultrafine powder preparation devices used in various industrial fields mainly include impact mills, ball mills, roller mills, vibration mills and jet mills. These devices are all dry ultrafine powder preparation and sorting devices, which are relatively simple in terms of crushing principle, and have problems such as low efficiency, high energy consumption, contamination of grinding media, inability to integrate crushing and sorting, and non-continuous production. [0003] Wet high-pressure water jet crushing technology and devices have been...
