Embodiment Construction

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0018] Such as figure 1 with figure 2 As shown together, a roller crusher includes a crusher frame 1. A number of crushing rollers driven by a power device are rotatably installed on the crusher frame 1. The plurality of crushing rollers are arranged in parallel, and the rotation of two adjacent crushing rollers is opposite. And a crushing cavity is formed between two adjacent crushing rollers, and the difference between the number of crushing rollers and the number of crushing cavities is 1.

[0019] There are 6 crushing rollers.

[0020] The power device includes a first motor 21 and a second...

Abstract

The invention belongs to the technical field of mining machinery, and especially relates to a roller-type crusher. The roller-type crusher comprises a crusher rack. A plurality of crushing rollers driven by a power device are rotatablely arranged on the crusher rack. The plurality of crushing rollers are arranged to be parallel to each other. The rotation directions of two adjacent crushing rollers are opposite and a crushing cavity is formed between two adjacent crushing rollers. The difference between the amount of the crushing rollers and the amount of the crushing cavities is 1. The roller-type crusher is advantaged by simple structure, reasonable design, more crushing times and high working efficiency.

Description

Technical field [0001] The invention belongs to the technical field of mining machinery, and particularly relates to a roller crusher. Background technique [0002] The roller crusher uses gap-fitting and relatively rotating crushing rollers to crush the ore passing between the two crushing rollers. Commonly used roller crushers are divided into double-roll crushers and four-roll crushers according to the number of crushing rollers. Both the double-roll crusher and the four-roll crusher must use two crushing rolls to complete one roll, and the number of crushing rolls is twice the number of crushing. [0003] The roller crusher of the above structure uses a large number of crushing rollers, a complex structure, high cost, few crushing times and low work efficiency. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a roller crusher to solve the technical problems of a large number of crushing rollers, a complex structure and ...
