There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary - all of which have their own unique benefits.
The maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. The friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls. Solution ...

The test bench roll crusher/splitter (fig. 2) consists of two sets of 20-inch diameter steel rolls mounted in two vertical, fixed stanchions. A 175 Hp, gasoline engine furnishes power to 3 hydraulic pumps.' Two separate hydraulic motors,with speed-reducing gear drives, power the bottom roll of each set.
The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers. This was the predecessor to the high-pressure grinding rolls (HPGR) crusher, which became popular in Europe for applications in the cement industry. The introduction of the HPGR in minerals processing sparked at the beginning of the 2000s.
Double-roll crushers offer up to a 3:1 reduction ratio in some applications, depending on the characteristics of the material. Triple-roll crushers offer up to a 6:1 reduction. As a compressive crusher, the roll crusher is well suited to extremely hard and abrasive materials.
Roll Mills are protected against damage due to uncrushable like tramp iron by a floating roll which can evade under such conditions. Similar to the hydraulic retraction system of the …
