Failure rate analysis of Jaw Crusher: a case study Sādhanā
1.2 The jaw crusher. Crushing is the first stage of size reduction of mined rocks. Primary crushers are heavy-duty machines, used to reduce the run-of-mine (ROM) ore down to a size suitable for easy handling. A line diagram of a double toggle jaw crusher and its main components is shown in figure 2.

6 Replace the bearing or movable jaw plate. There is a beating or percussion when the movable and the fixed jaw plate work. Cause analysis: 1 The fastening bolts of the jaw plate are loose or dropped. 2 The discharge opening is too small, and the bottoms of the two jaw plates collide with each other. Solutions: 1 Tighten or matching bolts.The radial bearings are most commonly special cylindrical roller bearing designs, featuring two rollers per pocket with differing roller lengths. The axial bearings typically combine a tapered thrust bearing and cylindrical thrust bearing. Figure 1: Jaw crusher.

Example 71 The size analysis of a gold bearing ore crushed in a jaw
Example 7.1 The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80 % passed through a 2000 micron sieve. Further size reduction was completed in a 1.0 x 1.5 m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the commencement of grinding.
