Australia is a highly developed, stable democracy with a federal-state system. Tourist facilities are widely available. Australia mineral resources is the most important components of Australia wealth, and occupy an important position in the world such as Bauxite, Black Coal, Brown Coal, Copper, Diamond, Gold, Iron Ore, Lithium, Magnesite, Manganese Ore, Mineral Sands, Nickle, Phosphate, Shale Oil, Tantalum, Uranium, Vanadium, Lead, Silver, Zinc and so on. Australian mining of mineral resources most exports. 2002-03, mineral products export fiscal accounts for Australia's total exports in (including service export) 37%, about 549 billion, accounting for Australia's GDP (DGP) 8%.

Crushing technology and equipment

Grinding is large materials in mechanical forces granularity decrescent process. Grinding is an important link of mineral processing. Crushing can be divided into four stages: the crushing, grinding, superfine crushing, superfine grinding. Crushing process is the high-energy homework, crushing process of basic principle is "much more fragile less grind".

Large stone by vibrating feeder evenly send into jaw crusher for crushing, after primary crushing the stone was sent cone crusher by belt conveyor, finely are sent into the vibrating screening, screening gives several different specifications of stones, satisfy requirement of particle size by belt conveyor are sent to finished stone pile, Do not satisfy the requirements of particle size by belt conveyor regurgitation feeding stones to cone crusher again, forming closed-circuit circulation many times. Finished product granularity according to users' demands combination and classification for the protection of environment, can be equipped with auxiliary of the dust removal equipment.

Crushing flow sheets

1. A period of crushing flow sheets. A period of crushing flow sheets since grinding machine for commonly used to provide appropriate feed stocks, often with autogenously grinding institutions into system. This simplified process, equipments little, workshop covers an area of an area small.
2. Two paragraphs crushing flow sheets. This process more for small factory adopted.
3. Three sections of crushing flow sheets. This process is the basic form with three legs open and three sections of a closed-circuit two kinds.
4. To take the crushing flow sheets ore washing work. When feeding containing mud 3mm (-) quantity of more than 5% ~ 10% and moisture more than 5% ~ 8%, should be in crushing flow sheets add ore washing work.

The crushing and screening plant with JC jaw crusher and HPC cone crusher produced Our company can well control the particle of composition, and low power consumption. For example Our Screening And Crushing Plant used in Queensland mines, its processing capacity is 150t/h, and fineness is 7mm, partial output of 300mm is 26 percent.
