In this stage the ore is crushed in cone crushers to less than 10 to 15 millimetres. This material is the feed for the grinding mill. For mineral processing project after blasting crushing and screening system is always the first stage to reduce the big raw ore lumps to proper small particle size for following mill grinding system. Normally to reduce the big ore lumps to small particles two to three stages crushing is required.

    Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry slurry is used as feed for rod or ball mills to avoid dusting. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design. Many times the single heaviest equipment item in the entire plant is the primary crusher
