Understanding comminution: Compression versus impact crushing
A steady compression force applied by closing the product between the mantle (or jaw) dies and the crushing chamber’s wall. Compression crushers such as cones and jaw crushers normally have lower reduction ratios than impact crushers like a horizontal or vertical impact crusher. However, they offer much greater control over the output-as
