Minerals and energy industry are the pillar industry of Indonesia, and it play an important in the GDP and exports. Indonesia is the world's 9th largest coal producer, and it's the largest coal production, consumption and exporting country in Southeast Asia. It's the world's 3rd largest coal exporter, after Australia and China. In the past 8 years, the Indonesian coal production more than doubled. Coal production in 1996 was 50 mt, and 2003, increase 3%, it's 116 million tons. Proven coal reserves of Indonesia are about 38.8 billion tons, mainly distributed in Kalimantan, Sumatra and Sulawesi regions. Most of the mines are open pit mine, conditions are good, and the quality of coals are better.
Currently, there are more than 35 bituminous and sub bituminous coal production in East Kalimantan, South Kalimantan and Sumatra. Almost all the coal in Indonesia are mined in open pit, and only a small serveral of mines are underground mine. Existing large coal mines in Indonesia, Bumi Resources, Adaro company, Jitai expansion Jaya Agung company, Banpu company and PTBA coal company. The five companies in Indonesia share more than 75% production of Indonesia. To meet the domestic demand and export of coal, many coal producers in Indonesia are planning to increase the production in the existing circumstances, in addition, a number of new projects will be commissioned in the nest few years.
Moreover, Indonesia's coal exports in recent years, show a rapid growth, and the mining industry just take off. In Indonesia, in various large and small coal mines, you can see the SBM coal crushing plant presence.
Coal processing generally include, excavation, crushing, and other processes. Which, broken, including jaw crusher, cone crusher, impact crusher etc. Jaw crusher for primary crushing, the back of the crusher for fine crushing process manufacturing conditions. In broken before Miners used an electric drill and the like, separation of the coal from the mines down the top, commonly known as pre-broken. and then was sent to the ground, of course, open-pit mining, that having this link, directly on the ground can be broken. and jaw crusher made of special materials by two strong jaw plates crushed chunks of coal. This produced the coal, the minimum can reach 25mm. fully able to provide to the users. If you need smaller pieces of coal, you can use cone crusher and impact crusher. they can be further broken coal to produce sand-sized coal particles.
The manufacture of some of the new coal technology, coal. Coal demand increasing in recent years. Coal is coal, continue milling ground into fine powder and then used as fuel technology. Pulverized coal particle diameter for the 0.05-0.1mm. rely mainly on coal production, roller mill, and coarse mill, ball mill like. pulverized coal sufficient to enable combustion to improve fuel efficiency results. Shanghai SBM is a crushing mill with 30 years experience in the production of the enterprise. For the Indonesia Coal crushing and milling production line. These lines are in Indonesia has been widely used.
Would also like to mention is that on the tailings, mineral extraction will always have some when the tailings, the tailings contain minerals usually less, very few people are concerned, but they can have very serious pollution, SBM crushers and grinders to good protection of the environment, processing of tailings. the one hand, the heavy use of the tailings, while reducing environmental pollution.
