3.0 Equipment description of MPR200T
This machine is a heavy duty Rasper ideally suited to the harsh environ-
ment of tyre shredding.
To ensure its durability t he main housing is fitted with replaceable wear
plates and the rotor is manufactur ed from wear resistant and hardened
steel.
Other features include a quick-change kn ife system and a rotor, which is
easily removed.
To enable the screen to be easily cleaned or changed, the screen fits into
a hydraulically operated swinging cradle t hat allows it to be lowered from
the cutting chamber in a matter of seconds.
The transmission system is a combination of 2 motors placed on each side
of the machine, and a belt drive bet ween the motors and the rotor shaft.
The number of belts in each side is 10 pieces.
Mechanical overload protection is provided by friction clutches.
The main housing is construct ed with double skinned walls. The wear
plates are mounted on the inside of the inner skin and the main bearings
are mounted on the outside of the outer skin.
In the case that material such as dust, rubber granulates etc. does get
forced between the wear plates, the ma terial falls into the void between
the skins rather than into the rotor bearings. For further protection of the
bearings a wiper has been mounted between the skins.
Should the rotor and flywheel be stalled by extreme overload, a differential
speed detector protects the transmission.
The Rasper is equipped with a Serv ice Platform to enable service and
maintenance work to be carried out with ease.
