Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment:

[0024] Such as figure 1 , figure 2 As shown, the drum crusher includes a front end plate (1), a rear end plate (2), a brace (3), a drive shaft (7) and a screening component. One end of the transmission shaft (7) is fastened to the central hole of the rear end plate (2) through a connecting piece, and the other end passes through the central hole of the spiral material guide plate (9) and is tightly connected with the spiral material guide plate. The outer edge of the plate is fastened on the front end plate (1), and the front end plate (1) and the rear end plate (2) are connected by tie bars (3) distributed on the circumference. The front end plate (1), the rear end plate (2), the transmission shaft (7), the spiral material guide plate (9) and the bracing bars (3) constitute the barrel bracket of the crusher. The front end plate (1) and the rear end plate (2) are provided with a ...

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 ...
