Fill product to be crushed
The fill hopper B and the crushing chamber can accept product
at grain size of up to 50 mm. Fill the crushing chamber and the
fill hopper only while the machine is running.
The fill hopper is not intended to store product to be crushed;
its sole purpose is to feed the material into the crushing
chamber while at the same time keeping the operator from
unintentionally reaching into the crushing chamber and at the
same time keeping crushed product from being ejected.

If the crushing chamber W is filled with more than 2/3 , then the
fill hopper guide plates could be damaged; the moving breaker
arm would force the product behind the breaker arm and into
the crusher housing.
