The mining process starts with cable shovels (CAT 7495) that dig and load the material directly into the mobile size rig (MSR) and mobile crusher rig (MCR) systems. The primary crushers are four Primary Crushing (coarse crushing): In primary crushing, ore or run-of-mine ore (up to 1 m in size) is crushed down to about 10 cm and it is done in a jaw or gyratory crusher. ii. Secondary Crushing (intermediate crushing): In this case, ore is crushed from 10 cm to less than 1 –2 cm size; for this purpose jaw, cone or roll crushers are used.Mineral dressing (= Orebeneficiation) جامعة الملك عبد

The crushers/sizers break up clumps of oil sands into loose sand and crush any oversize material, such as ice or petrified wood. The crushed ore is dumped onto conveyors, which transport the loose oil sands to a storage pile or surge bin.OPP: Ore Preparation Plants Explained Oil Sands Magazine

Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm (75 mmThe process Comminution involves size reduction and size-wise classification called as screening/ separation.
