<p>Crushing ratio is an important evaluation indicator to measure jaw crusher and it refers to the ratio of the raw material granularity and the precision of the crushed product. It indicates the reductive degree of the raw materials after crushing. After ore is crushed, its particle size is reduced, and the ratio of the particle size of ore before and after crushing is called crushing ratio which indicates the multiple of the granularity shrinking after the ore is crushed. The calculation methods of crushing ratio are as follows:</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years.
