Mineral processing crushing techniques

Crushing is the first stage in the comminution process. This is usually a dry operation, which involves breaking down the ore by compressing it against rigid surfaces or by impacting it against hard surfaces in a controlled motion flow. This process step prepares the ore for further size reduction (grinding) or for feeding directly to the classification and/or concentration separation stages. Tailings are usually not generated in this process step. Typical types of crushers are: jaw crushers, gyratory crushers, cone crushers, roll crushers, impact crushers.
