A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8.

And the most common one is double-roll crusher. According to the surface of rolls, it can be divided into smooth roll crusher and toothed roll crusher. (The following roll crusher refers to "smooth roll crusher".) Applications of roll crushers Roll crusher is applied more widely than other crushers because of its small volume and cheap price.
The load conditions in the roll crusher, however, are usually point to face or face to face load conditions, which cause a larger contact area and therefore a slightly higher breaking force to be considered by a conversion factor (Schmidt, 2011). The method shows good results, however, for single particle crushing and low comminution ratios.

Picture of crushing rollers is as follows. Roll crusher is mainly composed of roller, roller support bearing, hold-down device, adjustment device, driving device and so on. when discharging materials, we can realize adjustment of discharging granularity by means of adjusting distance between the two rollers.
The roll crusher has two cylindrical rolls, which are designed as fixed (2) and retractable (4). The retractable roll is pretensioned with two hydraulic cylinders (3), which press it against spacers, which in turn are supported by the bearing block of the fixed roll. ...
