It is usually classified into three types: single-roll crusher, double-roll crusher and four-roll crusher. The double-roll crusher is the most commonly used one in the factory, but there are still many cases where it is not suitable. While the more efficient and reasonably designed four-roll crusher can bring a better crushing effect.
