grinding circuit crusher

difference between open and closed circuit jaw crusher

Open or Closed Circuit Crushing High-speed, short-throw crusher, such as the Type R or cone, will reduce practically all of its product to a one-way dimension not exceeding the close-side setting of the crusher; hence, in a closed-circuit operation, if the crusher-setting is anything less than the square-opening product size, practically all of the material will be crushed
