The dehusked Rice enters the gap between the abrasive cone & perforated sheets and is dragged along by the rough surface of the rotating cone. The rubber brakes tend to stop it and cause it to pile up against their sides and undergo a strong, swirling and revolving movement. The external grain layers are finely grounded due to scouring and rubbing against surrounding grains, abrasive surface of cone and perforated sheets. The machine can deal with any variety of rice of any size, shape or texture. The whitening action can be adjusted by positioning the cone and brakes. The spindle holding the abrasive cone is gripped from three points; bottom, middle and top (third brass system) having two bearings at each point, ensuring vibration free running of the machine.
