6 Crushing of Ore in a roll crusher, and Determination of average size by sieving. 16-18 7 To determine the reduction ratio, theoretical capacity, and actual capacity of a roll crusher. 19-21 8 To study the effect of grinding with grinding time in Ball mill. 22-25 , 9 To study the effect of grinding with frequency (RPM) in Ball mill.

The feed particles entering the crusher are drawn into the Gap between the Rollers by the Rollers rotating motion and the friction angle formed in the Gap, between the Rollers and particles entering the Gap. This is referred to as Nip Angle.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste

In a Roll Crusher, feed of known size is passed between two heavy smooth faced metal rolls rotating on parallel horizontal axis. Solid particles caught between 

The material to be processed falls into the crushing chamber of the 911MPE-JC100 Crusher via a guide chute and is crushed by crushing action of a static and a dynamic jaw plate until it passes the preselected gap of the crusher. The stepless gap setting can be adjusted via a hand wheel and a mm scale from 0 mm to 25 mm (contact of the jaw plates).

Sep 16,  · Roll crushers consist of two or more adjacent rolls placed parallel to each other and rotated in opposite directions. Single roll crushers are also available which rotate a single roll against a fixed breaker plate. Mineral or rock particles placed between the rolls are nipped and then crushed as they pass between the rolls.
