AZ15WLM Pre-Breaker

A small pre-breaker for applications where heads are not included in the waste stream.

The AZ15WLM is a small pre-breaker best suited to applications where large heads are not included in the stream.   Capable of up to 10T/hr the AZ15WLM is a good choice for smaller ovine rendering facilities where all boning room and kill floor material can be processed.  The smaller grab of this machine means that for bovine facilities, the unit can only be used where heads are not included in the stream.

Key Features
