It is based on the Constant Rate of Traverse (CRT) principle. The sample is held between two jaws; the upper one is a stationary jaw while the other end is made to move at a known fixed speed with the help of Motor, Gear Box and Lead Screw arrangement. The load exerted on the Stationary jaw is sensed by a sensor connected with load cell which directly indicates the load in Digital form in Newton and kg.

Electrically operated to work on 220 volts A.C. Recommended for grinding of dry plant samples. Also for a great variety of commercial dry materials.
