Stone Crushing Plant has a widely used at present, and mainly used in concrete mixing stations, premixed dry mortar, power plant desulphurization, sand gravel plant and so on. Stone Crushing Plant can process pebble, limestone, coal gangue, quartz, iron ore, basalt, diabase etc.
The well-known, typical set-up for a stone crushing plant in an aggregate quarry was initially not purpose designed to make optimal products, but to provide an effective size reduction of the blasted rock, very much based on technology from the ore mines. Especially secondary gyratory crushers in many plants had a tendency of producing extremely flaky materials, which could be hard to repair for the (eventual) tertiary cones.
A modern, well designed and operated three-step, traditional plant can, however – much depending on the rock type – deliver quite satisfactory, clean and cubical products in the sizes above approximately 8 mm. The most critical size range for such a plant is between approximately 2 and 8 mm, where it is extremely difficult to obtain a good, cubical shape. As for the finest fractions, their particle shape will for most rock types be a function first of all of the mineral texture – but the crushing process does not assist to cubicity.
A quarry set-up in the “typical” way could then be:
1. Primary crushing (Feed size: 300-2000 mm), – preparation for next stage.
2. Secondary crushing: (Feed size: 50-400 mm, < 40 mm) – middle stage, potential final
stage in smaller operation/gravel.
3. Tertiary crushing: (Feed size: 0-100 mm) – reduction ratio small – focus on shape.
Entire major aggregate requirement < 20mm
4. Quaternary crushing: Cubical Manufactured Sand.
