One-sided feeding top hydraulic supporting gyratory crusher

Abstract

The invention relates to the field of crushing equipment of ores or rocks, in particular to crushing equipment which crushes exploited bulky ores or rocks (the grain sizes are 700mm) to ores or rocks(the grain sizes are smaller than 350mm). The gyratory crusher comprises an upper rack body assembly, a middle rack body assembly and a base assembly as well as a movable cone assembly, a rack wheel eccentric bushing assembly, a pinion transmission assembly and an upper hydraulic supporting lifting suspending assembly in eccentric pendulum movement; a feed inlet is formed in the upper rack body assembly, and a discharge port is formed in the base assembly. The crushing ratio: the proportion of the feeding grain and the discharging grin, of the equipment is increased by enlarging the feed inletand the inner crushing cavity, and the mounting and repair difficulty is reduced by means of upper maintenance and replacement of quick-wear parts.

Description

technical field [0001] The field that the present invention relates to is a crushing equipment for crushing large ore (grain size>700mm) or rock to a particle size below 350mm, specifically a gyratory crusher with single-side feeding and top hydraulic support. Background technique [0002] The gyratory crusher is a cone-type crushing equipment for large pieces of ore or rock (grain size>700mm). the goal of. The upper part of the gyratory crusher feeds the material, and the crushed material gradually shrinks along the crushing cavity from the upper part to the lower part, and moves downward successively with the swing of the moving cone, and the crushed material is discharged from the lower part of the crusher; the characteristics of the existing gyratory crusher One is the uniform feeding of the double-edge beams, which requires a large feeding space, and the outer section of the upper feeding port is circular, and the size of the feeding is formed by the inner side o...

Problems solved by technology

The upper part of the gyratory crusher feeds the material, and the crushed material gradually shrinks along the crushing cavity from the upper part to the lower part, and moves downward successively with the swing of the moving cone, and the crushed material is discharged from the lower part of the crusher; the characteristics of the existing gyratory crusher One is the uniform feeding of the double-edge beams, which requires a large feeding space, and the outer section of the upper feeding port is circular, and the size of the feeding is formed by the inner side of the outer circle fixed broken liner and the outer side of the movable cone liner. According to the circular ring, the angle of engagement in the crushing process is not greater than 28°, and the height of the equipment must be increased to increase the feed particle size; the second feature is that the hydraulic cylinder supporting the moving cone is at the bottom of the base, and a special maintenance track needs to be set up during maintenance. car and large maintenance space
