What Type of Crusher Is Best for Primary Crushing?
网页2021年3月25日Roll Crushers are compression-type machines, so output gradation is controlled mainly through the gap setting between the rolls. A wider setting results in a coarser product. A wider setting also provides greater throughput. Single Roll Crushers feature a low-speed crushing roll that crushes material against a curved crushing plate.
