Usually, most of rocks and stones are suitable for two crushing stages. During the secondary crushing stage, materials bounce round within the crushing chamber until it is small enough to escape. After the secondary crusher and crushing, customers can get products according to the requirement of market. The cone crusher is favoured in igneous rock quarries. Common types of secondary crushers include the cone crusher, impact crusher and vertical shaft impactor. Impact crushers have the advantage of giving the cubical shape that is required for the concrete industry, they can produce large quantities of fines, up to 40% of output in some instances, resulting in excessive waste. Each stage of crushing (primary and secondary) can be expected to reduce the size of the material feeding through it by between 60% and 80%.Answer: The secondary crusher breaks rock fragments down into sizes that are suitable for the market. The size of the final product can be adjusted by adjusting the gap between the rotor blades and breaker bars attached to the chamber edge. A variety of crushers can be used as the seconday crusher depending on the rock type. However, the selection of secondary crusher should be depended on the production of greater quantities of final product. Rock-on-metal impact is suitable for the crushing of soft rocks, such as limestones, however high wear rate on the rotor tips makes this method unsuitable for abrasive igneous rocks.

Portable conveyors mounted on crawler orwheels are also used in mechanised quarries and surface mines.Belt Conveyor Types Permanent: This type of conveyors is installed for the life of the mine. Theyare used in main line, slope, long overland installation, preparation plants andstockpiles.. Such belts can work in slopeup to 70-800. Cable Belt Conveyor: Where the belt is carried on moving wire ropes and thetractive force is applied through the rope to the belt is known as cable beltconveyor.7. High Angle Conveyor: These are special type of conveyor belt arrangementused for negotiating steeper angle of inclination. Shiftable:Used in continuous surface mining this type of conveyor ismounted on skid or supporting structures aligned together and the whole canbe shifted transversely to follow the advancing working face. Portable:These are characterised by relative ease of assembling anddisassembling to facilitate advances and recovery in development and retreatoperations in underground mining. NALCO (in collaboration with France) is using such system for longdistance conveying of bauxite in their mines in Orissa. Sandwich belt conveyor is a type of such belt conveyor.
