  • 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 stonesMill (grinding) Wikipedia,A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

  • grinding of the ores

    Semi autogenous grinding and autogenous grinding circuits are used for grinding the ore. Both rod mills and ball mills are used for this purpose. Capital investment and operation costs of grinding equipment are high. Hence economics play a large part in planning for the degree of crushing and grinding performed to prepare ore for beneficiation.1 Teeth adapted for crushing and grinding are (a) incisors,Premolars and molars are specialized for crushing and grinding the food particles. Hence, the correct answer is option (c). Reasons for incorrect answers: Option (a) is given as, “incisors”. Incisors are a narrow-edged tooth at the front of the mouth. It helps in biting and cutting, not crushing and grinding

  • Rittinger and Kick's Laws of Crushing

    I happen to be one of those who believe that Rittinger probably meant what he said when he wrote what Stadler has quoted, “the increase of the surfaces exposed is directly proportional to the force required for reducing” “and therefore also to the work absorbed in effecting the separa­tions.” (The italics are now mine instead of Rittinger’s or Stadler’s.)
