Problems solved by technology

The original wet ore is easy to stick 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

Embodiment Construction

[0016] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0017] like figure 1 , figure 2 and image 3 As shown, a roll crusher 1 includes a feed hopper 2, the feed hopper 2 is an arc-shaped plate structure, and the arc-shaped plate structure is an arc that expands from bottom to top. When the wet ore falls onto the feed hopper 2, since the contact mode between the wet material and the feed hopper 2 is point contact, it is difficult to stick to the feed hopper 2. And there is no feeding dead angle in the arc-shaped structure, and the wet material will not be stuck on the feeding hopper 2, which further enhances the smoothness of feeding.

[0018] In order to further reduce the sticking of wet material on the feed hopper 2, the feed hopper 2 is configured as a circular arc plate structure. The circular arc plate structure is more rounded than the ordinary arc plate. After the material collid...

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, which is a curved plate structure. The roll crusher has the advantages of preventing sticking and blocking.

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. As the scale of the factory expands, the problem becomes more prominent. [0003] In order to solve the above problems, improve labor efficiency, and ...
