Compression Crushing Machinery for Sale

As the name implies, crushing by compression is done between two surfaces, with the work being done by one or both surfaces. Jaw crushers using this method of compression are suitable for reducing extremely hard and abrasive rock. However , some jaw crushers employ attrition as well as compression and are not as suitable for abrasive rock since the rubbing action accentuates the wear on crushing surfaces. As a mechanical reduction method, compression should be used as follows:

1. If the material is hard and tough
2. If the material is abrasive
3. If the material is not sticky
4. Where the finished product to be relatively coarse (38mm) or large r top size
5. When the material will break cubically

The Jaw crushes by compression without rubbing. Hinged overhead and on the centreline of the crushing zone, the swinging jaw meets the material firmly and squarely. There is no rubbing action to reduce capacity, to generate fines or to cause excessive wear of jaw plates.
