Enhancing Coal Mining Operations with Track Mounted Crushers in Indonesia

Indonesia is one of the world's largest producers and exporters of coal. Since 2005, when it overtook Australia, the country is leading exporter in thermal coal. A significant portion of this exported thermal coal consists of a medium-quality type (between 5100 and 6100 cal/gram) and a low-quality type (below 5100 cal/gram) for which large demand comes from China and India. According to information presented by the Indonesian Ministry of Energy, Indonesian coal reserves are estimated to last around 83 years if the current rate of production is to be continued.

Regarding global coal reserves, Indonesia currently ranks 10th, containing roughly 3.1% of total proven global coal reserves according to the most recent BP Statistical Review of World Energy. Around 60% of Indonesia's total coal reserves consist of the cheaper lower quality (sub-bituminous) coal that contains less than 6100 cal/gram. There are numerous smaller pockets of coal reserves on the islands of Sumatra, Java, Kalimantan, Sulawesi and Papua but the three largest regions of Indonesian coal resources are: 1. South Sumatra; 2. South Kalimantan; 3. East Kalimantan.

The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions (mainly in Sumatra and Kalimantan). Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust increase in coal production, coal exports and domestic sales of coal. The latter, however, has always been rather insignificant as domestic consumption of coal is relatively small in Indonesia.

But in recent years there has been a rapid increase in domestic coal sales because the Indonesian government is committed to its ambitious energy program (implying the construction of various power plants, mostly coal-fired because Indonesia has plenty of coal reserves). The program has been a success, as the country has started to bank on domestic consumption rather than relying on traditional coal exports (which have always suffered from fluctuations in global coal prices).

Therefore, in order to contribute to more cost-effective coal mining operations in Indonesia, Adaro Indonesia opted for the larger, 770-tonne, model Gaofu coal crusher developed by Xinxiang Gaofu Machinery Co., Ltd. This toothed roll crusher is the largest in the Gaofu coal crusher range and is driven by a male gear-driven system. It is equipped with a hydraulic automatic retraction system for overload protection, and an oil filtration system to ensure the gear system is clean and effective.

The Gaofu teeth roller coal crusher is mainly used for the coal of the gangue, shale, coal, cinder, slag, limestone, coke, galena, siderite, sphalerite, limonite and other materials. The equipment is mainly used for large-scale coal picking plant or coal preparation plant. It can not only screen the coal gangue, but also crush it into particles, which is suitable for crushing toughness materials, such as limestone, shale and gangue. The device has novel design, durable, widely applicable, high efficiency, improved effect, easy cleaning, practical, reliable, low cost and so on.

With the accelerated mining of high-quality coal resources in Indonesia, currently about 60% of the coal mined in Indonesia is of high quality and 40% is of medium quality. Those high-quality coal resources are exported to global markets mainly in Asia, as China and India are the two largest coal consumers in the world. Indonesian coal exports are expected to hit 371 million tons in 2020, according to Minister of Energy and Mineral Resources, Mr. Arifin Tasrif, an impressive growth rate for a mature commodity market.

In conclusion, the track-mounted crushing plant is an ideal choice for the coal industry and supports the Indonesian government’s energy program. The way to select the equipment for coal crushing depends on the characteristics of the coal. Egypt’s Ministry of Petroleum and Mineral Resources estimates that the country’s coal reserves could reach 71 million tons by 2017. Indonesia has a higher number of coal reserves which reached 30 billion tons in 2020. This makes Indonesia a strong player in the global coal industry.

By enhancing mining operations with track-mounted crushers, contractors in Indonesia are able to save on their operational costs. Using this advanced technology, they are able to significantly reduce their carbon footprint and increase their productivity. Sustainable mining operations and environmental protection are no longer conflicting goals but rather mutually beneficial.
