Roller crusher

Abstract

The invention discloses a roller crusher. The prior crusher mainly performs single-stage crushing by an impact or extrusion mode, so that the crusher has large equipment attrition and large power consumption, cannot perform sieving in time, is difficult to control the granularity of materials, and cannot feed back alone. The invention provides the roller crusher in order to solve the problems, wherein one end of a driving shaft (7) is firmly fixed on a central hole of a back end plate (2), and the other end of the driving shaft (7) is firmly fixed on a central hole of a helical guide plate (9); the outer edge of the helical guide plate is firmly fixed on a front end plate (1) which is connected with the back end plate (2) through a lashing strip (3); one end of a sieve plate (4) is firmly fixed on the lashing strip and forms steps for accommodating and lifting the materials; a screen mesh (6) is coated on the outside of the lashing strip and the sieve plate to form a cylinder; and an outer cover which is taken as a receiving bin (13) is arranged outside a secondary sieve. The roller crusher has reasonable design, simple structure and low maintenance and management cost, can sieve qualified materials in time, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to processing equipment for crushing, grinding or crushing, in particular to equipment for crushing and sorting solid materials. Background technique [0002] At present, mineral processing plants, quarries, slag treatment units, and construction solid waste treatment units mainly use jaw crushers, impact crushers, cone crushers, spindle crushers, hammer crushers, and extrusion crushers to crush brittle materials. These crushers mainly achieve the purpose of crushing through impact or extrusion, which requires a large investment in equipment, high maintenance and management costs for various wearing and wearing parts, high management costs, and large power consumption; in addition, these crushers are single-stage Crushing and screening are difficult to control the particle size of the finished material, and it is impossible to return the material by a single machine, or if the material is broken multiple times and the material is ...

AI Technical Summary

Problems solved by technology

This application exists: ①Because the material is crushed under the impact of the steel ball, the steel ball and the crusher wear a lot, and the maintenance cost is high; ②The material is discharged from the discharge hole connected to the inner screen and fixed on the barrel Part of the substandard materials will be shaken out due to vibration, and the screen is easy to block; ③The materials and steel balls can only be lifted with the rotation of the cylinder under the action of centrifugal force. Only when the rotation speed meets the requirements, the materials and steel balls In order to rotate under the action of centrifugal force, the power consumption is large
