“LYNX” Laboratory Pulveriser is a disc type grinder, designed to grind virtually any material to produce a fine mesh sample in one operation. It is a self contained grinder, with a rotary disc, having a planetary  movement in a vertical plane. Grinding is done between two discs – one stationery and the other revolving eccentrically at high speed. The discs are made from heat treated alloy steel. With the help of a convenient hand wheel, the size of the final product can be adjusted. This can be done, even while the machine is in operation. A self locking device holds the hinged grinding chamber in place and affords easy and quick access to it, for removal of ground samples and for cleaning. The Pulveriser has a capacity of reducing about half of a kilogram of a quartz type sample to 100 mesh in about a minute. The Pulveriser is fitted with a 3 H.P. motor, a ‘V’ belt pulley drive and mounting.
