2010年8月1日 As a rule of thumb, one should consider that the maximum particle size which would physically/effectively be nipped by the rolls would approximately be 1.75 times the size of the operating gap. Generally, depending on ore type and process conditions, the operating gap would be about 2.0–2.5% of the roll diameter.

Hard Rock Gold Mining Equipment: Essential Gear Guide
One type of grinding mill commonly used in hard rock gold mining is the ball mill. This cylindrical device rotates around its axis and uses steel balls or other grinding media to pulverize the ore inside it. The rotation of the drum causes these balls to cascade and grind down the ore particles, resulting in a fine powder ready for extraction.
