Information about crushing technology, construction, working and maintenance of crushers for bulk materials is given in this article. Crushing Technology There are four basic ways to reduce size of a material: by impact, by compression, by shear or by attrition. Most crushers employ a combination of all these crushing methods.
A crusher is a major investment, so it's essential to select one with the potential to meet your needs into the future. This guide covers a few of the key points to consider before making a decision. But remember that your crusher is just one part of a wider process – always consider crushing in conjunction with screening and transport.
