Multi-stage mineral crushing mechanism

Abstract

The invention discloses a multi-stage mineral crushing mechanism. The multi-stage mineral crushing mechanism comprises a base, a rack, a driving motor, belts, belt wheels, a moving jaw, a fixed jaw, a connecting rod, roller groups and a gear, wherein the rack is arranged on the base; the moving jaw is installed on the base, and is hinged with the base; one end of the connecting rod is connected with the belt wheels, and one end of the connecting rod is connected with the moving jaw; the roller groups are two, and are connected and driven by the gear; rollers are installed on the rack; the driving motor is installed on the rack. The combined mode of a jaw-type crushing mechanism and a roller grinding mechanism is adopted for the multi-stage mineral crushing mechanism provided by the invention, can be used for greatly shortening the crushing time of minerals and improve the grinding precision, and improves the grinding efficiency greatly; moreover, non-cylindrical design is adopted for the rollers of the roller grinding mechanism, convex and concave arc surfaces are matched in rolling, and the creative design increases the meshed angle between mineral particles and the rollers, so that a crack crushing effect is provided in the extruding and crushing process, and a mechanism with higher productivity is formed.

Description

technical field [0001] The invention belongs to the field of crushing machinery, in particular to a multistage ore crushing mechanism. Background technique [0002] Ore crushing is an important process step in metallurgy and mining. According to different product particle size requirements, different crushing equipment is used, and material selection steps such as screening are even added. In order to meet the requirements of the material particle size in the production process of the industry, the roller mill has been gradually researched and applied. Jaw crushers can crush larger materials. If you want to crush smaller sizes, you need to grind them many times, which is not efficient. Roller mills are efficient, but cannot crush larger materials. If the current crusher needs to crush large-sized ore into a smaller size, the required equipment is larger in size, longer in consumption time, and inefficient.
