2-2 General Description

Mechanical Section

After the machine has been switched ON, a hydraulically controlled “swing-style” ram pushes a quantity of material onto the slow-running profiled rotor. The in-feed is controlled according to load.

The material can be placed (unsorted) in the hopper mounted on top of the machine. Pay attention to this material; it cannot contain any other metal parts except staples and nails. (The guarantee does not cover any damage to the machine as a result of metal parts being fed into the machine.) The material in the hopper is shredded by the cutters on the rotor. This shredding process is repeated as often as required until the whole diameter of the screen below the rotor has been reached.

The shredder can also be switched off with material still in the hopper.

Control

The machine is fitted with an automatic shut-down; i.e. when set to automatic, the machine switches off after a pre-set period in the time relay.

The ram feeds the shredding unit (rotor) with as much material as it is able to process. Upon reaching 70 to 90 % of rated current, the feeding of the ram will be stopped and automatically started again after the power consumption has fallen by 20% in comparison with rated current. If the high current is applied longer than 0.7 - 1.5 seconds, the main drive motor switches OFF and runs back after about 3 seconds standstill time. The ram plate also runs back while the rotor runs back. The drive motor then stops for another 3 seconds before starting again.

Duration of pauses and return and current settings can be adjusted.

NOTE: Any alterations should only be carried out after consulting the manufacturer.
