Embodiment Construction

[0021] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0022] Such as figure 1 , figure 2 and image 3 As shown, a roll crusher 1 includes a feed hopper 2, the feed hopper 2 is composed of at least three side plates, one of the side plates corresponding to the feed side of the feed hopper 2, Two or more pieces are arc-shaped plates, and the arc-shaped plates are arc-shaped structures that expand outward from bottom to top. When the wet ore falls onto the arc-shaped plate, it is not easy to stick to the arc-shaped plate because the contact mode with the arc-shaped plate is point contact.

[0023] In a specific application, for the convenience of processing and manufacturing, the feed hopper 2 is usually composed of four side plates. In order to reduce the adhesion of wet materials on the feed hopper 2, the corresponding feeding hopper The pair of side plates are the arc-shaped plates. In...

Abstract

The invention provides a roller crusher, which is used to prevent wet ore from adhering to a feeding hopper during feeding. It includes a feed hopper, the feed hopper is composed of at least three side plates, one, two or more of the side plates corresponding to the feed side of the feed hopper are arc-shaped plates. This roll crusher has the advantage of preventing wet material from sticking to the feed hopper.

Description

technical field [0001] The invention belongs to the field of material crushing equipment, and in particular relates to a roller crusher for preventing materials from adhering to a feeding hopper. Background technique [0002] In large-scale iron and steel refineries, ore raw materials need to be crushed before entering the rotary kiln for production, so that the particle size can meet the production requirements of the rotary kiln. The original wet ore is easily bonded to the feed hopper of the crusher during the crushing and feeding process, and the raw material feeding is not smooth, which is prone to blockage. Clearing blockages and stabbing materials brings greater physical labor intensity to workers, and the discontinuity of production also seriously affects the operation rate of raw material crushing and drying systems. With the expansion of the factory scale, the problem becomes more prominent. [0003] For the convenience of feeding, the feed hopper of the crusher i...
