Hammer Crusher. This type of cement crusher uses hammers or beaters to crush the raw materials. The hammers are mounted on a rotating shaft and strike the raw materials with high-speed impact to break them into smaller pieces. A hammer crusher is commonly used for crushing brittle materials, such as limestone, shale, and gypsum.
