The throw of Blake jaw crushers is determined by the hardness of the ore as well as the size of the machine [Mollick et al., Engineering & Mining J., 181(6), 69-171 (1980)]. It may vary from d in for hard but friable ores to 3 in for resilient material. The Big Bite jaw crusher (Kue-Ken Div, Process Technology Inc.) is a Blake double-toggle type in which the fulcrum pinion is positioned well

Impact crushers rely on gravitational or dynamic physical impact for size reduction of materials such as rock, concrete, gravel, and more, rather than through a standard compression-only method of crushing. Typically, impact crushers either use gravity to drop material onto a surface, or the material is fed into a chamber containing a high-speed rotor with hammers or blow bars that collide

Impact crushers reduce mineral materials such as concrete, asphalt and natural rock in size to produce a valuable commodity product. A fast spinning rotor throws the material against a solid stationary impact wall. The striking and impacting causes the material to shatter into smaller pieces. The result is a very homogenous and cubical product leaving the crusher box.

Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher , also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device .

Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material. A jaw crusher crushes only a small proportion of the original aggregate particles but an impact crusher crushes mortar and aggregate particles alike and thus generates a higher amount of fine material O’Mahony, 1990).

most effi cient method of size reduction when processing rocks, ores or minerals. The reason for this is because it is the best way to transfer energy from the drive motors to the material being reduced.

For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines. A good example of this is the overall milling of wheat grain

Because each crusher type has a limited reduction capability, sometimes several stages of crushing are needed to achieve the desired final product size. Primary crushers are important for kicking off production and initial product sizing for further processing. They receive the material directly from the blasting, drilling or dredging process. Secondary and tertiary crushers are utilized for
