According to the recent statistics of Indonesia Ministry of Energy and Mines, the coal reserves in Indonesia are about 58 billion tons, among which, 38.8 billion tons are proven. Besides, the coal mines in Indonesia are mostly open-pit mines with pretty good mining conditions. And the quality of coal is very good, with very low sulphur content. Every year, a lot of customers contact us for various machines to process coal and other minerals. In order to have better communication with Indonesian customers, we set up branch in Jakarta, Indonesia, which greatly improves the relation between customers and us. In this article, we mainly talk about a customer who needs 10tph coal grinding plant.
This customer contacted us in the year 2013, and said that wanted to set up a 10tph coal grinding plant. His coal had good quality. But there was one problem that the moisture content was a little bit high. After communication, we learned about his detail requirements:
First of all, the raw coal size is too large to be directly fed into grinding mill, so the engineer recommends a small jaw crusher to crush the coal into proper sizes. And the capacity, max feed size and output size of the jaw crusher are all suitable for the customer.
Secondly, the fineness of LM130M grinding mill can be adjusted between 80-325mesh, suitable for 200mesh sized coal powder production. The capacity range of LM130M vertical grinding mill is 10-15tph, suitable for the customer. And there is another important reason we choose this grinding mill for the customer: it can ventilate hot air to dry the raw material. Since the moisture content of the raw coal is a little bit high, so if we adopt LM130M vertical grinding mill, there is no need to equip another dryer to dry the coal, which not only save space but also reduce the investment cost.
The customer was very pleased with this design and happy for the attentive service of us. if you are also interested in coal grinding, feel free to contact us.
