  • Crushing in Mineral Processing

    Crushing in Mineral Processing

    The Compressive Strength of rocksis measured by crushing cylinder shaped (drill core) ore samples of 2″ x 2″ (51mm X 51mm). This techniques allows for a rock-to-rock relative comparison. The Bond’ Crushing Work Index is common to calculate the power needed to crush rocks from a given F80 size to a resulted P80 product size.

    Sep 11, 2020· The goal of comminution is to crush the ore into small particles that contain only one mineral. Dry crushing ore to ~1-5 mm particles is carried out on crude ore by compression and impact force. Jaw, cone, hammer, roll, and gyratory crushers are the tools used to do this. The next stage of size reduction, dry or wet grinding, is performed with tumbling and stirred mills. For wet grinding, ore …
