300 mm dia x 35 mm. Deep and - white cover disc and nut, also a radial
shaped fixed blade which carries the tablets along with it up to the
central height and lets them off while the drum is rotating. Thus the
tablets rub against each other without any hard impact. The drum rotates

is controlled by a timer ( imported time switch duration 1 to 15
minutes). The motor unit is housed in a elegant shaped steel cabinet
with shaft extended on one side upon which the drum rotates. Switches
with neon indicators and time switch are fitted on a panel and works on
220 volts 50C/s A.C. Digital models are also available with
