Abstract

The comminuting machine includes a housing provided with a rotary impact mechanism. A conveyor conveys infed material to the rotary impact mechanism which cooperates with an impact plate in disintegrating the infed material. A comb-like further comminuting structure follows the impact plate in the rotary direction and is arranged laterally of the rotary impact mechanism. The comb-like further comminuting structure extends over part of a discharge opening of the housing and is linked to a rear end of the impact plate. Displacement devices are provided for displacing the comb-like further comminuting structure between an operative position in which the comb-like further comminuting structure extends laterally of the rotary impact mechanism, and an inoperative position in which the comb-like further comminuting structure is pivoted away therefrom. Adjusting devices are provided for adjusting the comb-like further comminuting structure relative to the rotary impact mechanism.

Dependent claims

A comminuting machine comprising:

a housing for receiving material to be comminuted;
a rotary impact mechanism disposed in said housing and defining a rotational direction;
an impact plate constituting a first comminuting means arranged in said housing and extending along a top portion of said rotary impact mechanism for comminuting cooperation therewith;
said housing having a discharge opening disposed laterally of said rotary impact mechanism and having a predetermined width and a predetermined lenght as viewed in said rotational direction of said rotary impact mechanism;
further comminuting means following said impact plate in said rotational direction;
said further comminuting means covering said discharge opening along a length less than said predetermined length;
said impact plate defines a rear end as viewed in said rotational direction of said rotary impact mechanism;
said further comminuting means comprising a comb structure;
said comb structure containing a plural number of substantially parallel struts which are spaced from each other by a predetermined mutual spacing and which extend generally in said rotational direction of said rotary impact mechanism;
each one of said plural number of struts being provided with a multiple number of teeth directed to oppose said rotational direction and located on a side facing said rotary impact mechanism;
said impact plate defining a rear end as viewed in said rotational direction of said rotary impact mechanism;
and
said comb structure being linked to said rear end of said impact plate.
