In wet ball mills the bell wear is about 13 times that of the mill Liner wear, and in dry ball mills it is 10 times. Ja wet rod mills the rod wear is 11 to 12 times that of the Liner wear. The metal wear in ctushing rolls is about twice that in gytatory and jaw crushers, and that in crushers is, about 75% higher then that of dry grinding mills.

data set. The three groups of phosphates were classied as igneous, sedimentary and island type deposits. Figure 2 illustrates the location of the three most common forms of phosphate ore across the globe. The Island deposit type makes up a very small amount of the global phosphate ore market. The two main deposit types are igneous and sedimentary.

Generally all types of mills use mechanical forces and friction in the grinding process. A mill model that mainly uses mechanical forces (crushing) is the bar mill. This machine aims to reduce the material for sand production. The operation of the bar mill is based on a grinding process, it has a cylindrical shape (drum) and works horizontally.
