Sterling BP1012, BP1018 installation manual Opening the Granulator, Safety Switch

Page 13

The upper part of the cutting chamber is protected by the feed hopper, used to insert material to be granulated while the lower part is protected by the screen, and screen support. These components are fixed by a screw knob, unscrewing releases a safety switch key (Figure 1), which cuts off the electric supply to the motor, causing the rotor to stop.

The method of opening the granulator has been designed to restrict operator access, allowing the rotor and all moving knives to stop completely. To allow operator access more quickly could be dangerous as it might be possible to make contact with the granulator knives while they are still rotating.
