Santosh Scientific Instrument

Two hardened alloy steel rollers with 100 mm faces and 250 mm diameters. The rollers are fitted to a steel shaft and are mounted on heavy duty gunmetal bearings. The outside bearings are provided with heavy duty compression springs, which help in increasing the space between the rolls when a piece of material cannot be crushed. Square threaded bolts are provided to adjust the gap between the rolls. The drive is by a heavy duty motor, through reduction gear box or V belts to a set of gears, and further to the rollers. A hopper is provided for feeding the material. The arrangement is mounted on a fabricated steel frame.
