hydraulic double roll crusher

Hydraulic Double Roll Crusher avoids the problems of conventional crushing processes. When conventional processes treat gold ore, they tend to produce a large number of irregular, flaky particles. As a result, gold particles and gangue minerals enter the grinding stage without being fully liberated, leading to over-grinding in the ball mill and soaring energy consumption.

Our equipment uses low-speed, static-pressure crushing. Under high pressure, the material fractures cleanly along its natural cleavage planes, generating more cubical particles with a clear liberation boundary between gold and gangue. The equipment replaces “repeated impact” with “single-pass crushing”, reducing over-grinding energy consumption by more than 15%, while keeping gold particles intact before gravity concentration and improving recovery rates.
