May 05, 2021· These machines come in three main types, jaw crusher, cone and gyratory crusher, and impact crusher. Jaw crushers, occasionally referred to as toggle crushers, are the most common type of crusher. Material is compressed between a moving piece of steel and a stationary piece.
Compression crushers are used to break rocks and coarse particles larger than 3 cm in diameter. There are three main types of compression crushers: jaw crushers, gyratory crushers , and rolls. Equipment Design Jaw Crushers Jaw crushers consist of a rectangular frame with a fixed jaw plate and a jaw stock carrying the moving jaw.
Aug 15, 2012· The word impact makes sense that in this particular type of crusher some impaction is being used for crushing of rocks. In normal types of crusher pressure is generated for the crushing of rocks. But, impact crushers involve an impact method. There is a hopper one side that takes the crushing material into the machine.
