The Impact crusher operates much in the same method as a single impeller, with counter-rotating (two) impellers which not only impel the material against the breaker bars, but also impel material high inside the chamber to be fractured on other incoming feed. Uses impact to crush material. Crushing ratio is 20 to 1.
The vertical shaft impact crusher is a crusher whose main mechanism rotates around a vertical axis. The rock is fed into the crusher and impacted or thrown by a table/ anvil configuration or anvil ring, and is crushed by impact either by manganese wear plates or rock-on-rock strikes. Often used to make fines or manufactured sand. Uses impact to crush materials. Crushing ratio is 4-8 to 1.
The roll crusher is a crusher that breaks material by squeezing it between two revolving metal cylinders, with axes parallel to each other and separated by a space equal to the desired maximum size of the finished product. Uses compression to crush material. The crushing ratio is 2 to 2.5 to 1. There are also triple roll crushers able to handle larger feed sizes. They also produce fewer fines per pass than do cone type crushers. Roll crushers are good for producing road chips. Not recommended for abrasive rock, but very good crushing limestone.
