• Rock Crushing Process in Mining

    Let’s follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher “breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can’t fall through will

  • Crushing in Mineral Processing

    In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones
