Theory of crushing and its application to Jaw Crushers
Abstract
The article provides some theoretical foundations for the technical calculation and critical evaluation of jaw crushers. The general advantages of jaw crushers are high throughput, simplicity of design, low cost, and ease of repair; the disadvantages are the intermittent nature of operation and the presence of large oscillating masses, which generate strong noise during operation and cause vibrations in the factory building. Therefore, the issue of balancing a jaw crusher is very important for practice. Typically, one jaw is fixed, while the other receives oscillations from the drive mechanism. The author examines the design types of jaw crushers, the arrangement and shape of the jaws, and defines the optimal shaft speed, throughput, energy consumption, and other parameters (see the article).
