Indonesia is abundant with many types of mineral resources. The mining industry is an integral sector in economic development in Indonesia. Mining Industry is expected to grow by 10.9% from 2010 to 2015. Indonesia is one of the world’s largest producers of tin after China, coal (ranked the third largest thermal coal exporter after Australia and South Africa) and copper (ranked third largest, after the USA and Chile). It also produces significant quantities of gold and nickel. Minerals and related products represented nearly 20% of Indonesia’s total exports, with gold being the largest revenue earner. Indonesia is also a producer of bauxite, phosphates and iron sand, with potential for alluvial diamond production as well.
Crushing is the first stage in mineral mining and processing operation. In mineral crushing circuit, the feeder or screens separate large size rock from finer rocks that do not require primary crushing, and then convey the materials to the primary crusher. Jaw crusher, impact crusher, or gyratory crushers are usually applied for primary size reduction. The crusher productis normally 7.5 to 30 cmin diameter. According to production requirements, the primary crushed materials will be further crushed in secondary or tertiary crushing operation.
Grinding is distinct from crushing operation; it is the process of reducing materials to a powder of fine or very fine size, which involves size reduction to a rock, pebble or grain size.Material grinding is an integral step in industrial processing applications.In mineral grinding systems, the mineral from crushing and screening operations is first conveyed to coarse grinding mill and then fine grindingball mills or roller mill to reduce the material to the necessary product size range.
Many types of grinding mills have been developed for particular applications. Sometypesofmills canbeused to grind a large variety of materials whereas others are used for certain specific grinding requirements. Indonesia grinding industry development requires advanced grinding technology and high performance milling machine.
It is crucial to choose right crushing plant for a mine or quarry plant. Ore characteristics are a key factor in both crusher selection and plant design. Dry oresrequire greater provisions for dust suppression and collection, including dust enclosures aroundscreens, sealing on conveyor skirts, and vacuum and wash-down systems. Wet, sticky ores canplug chutes, reduce surge capacity, and decrease the live storage capacity of bins and silos. Toaddress this problem, chutes must be easily accessible for clean-up, and large feeder openingsmust be provided for bins, silos and tunnels. SBM can customize crushing and grinding machine for mining industry in Indonesia.
