The secret behind Barmac® crushers' efficiency is the unique crushing process. While most other crushers reduce rocks by pushing them by force against metal, Barmac® crushers also utilize the rock to crush itself. This so called autogenous crushing action results in lower cost per ton than any other impact crushing method.

The cone crusher working principle involves the eccentric motion of the main shaft. This motion is created by the rotation of the main shaft, which is supported by a bearing located at the top of the machine. As the main shaft rotates, it causes the mantle to move back and forth against the concave, crushing the rocks and ores between them.
