Vietnam is an important mining export country in Asia, especially the exportation of Limestone, iron ore, coal, granite and bluestone products. With many years effort, SBM successfully developed Vietnam market, SBM crushing machineries and milling equipments are very popular in many provinces, like Yen Bai province, Ho Chi Minh City, Nghe An, Tnh Qung Ninh and Hanoi. These mining equipments make up various mining crushing lines, sand making plants and mineral powder production bases

The analysis [45] proves that the maximum capacity of the ball-ring mill is obtained using 5 or 6 balls. Because earlier, as a rule, a greater number of balls was used, there is a possibility to increase the capacity by replacing the existing balls through a lower number of bigger balls. For example, in the EM-70 of FPM SA 9 balls of the diameter 530mm were replaced with 7 of 650mm. Such a modernized milling system can usually be set up on the existing gearbox. It should be noted that the costs associated with replacement of the classifier and the grinding elements are only slightly greater than the costs of the major repair of the mill. In the case where an existing mill has a grinding unit of the number of balls close to 6, the only way to increase performance is to increase the diameter of the balls, but this requires replacement of the mill body

There are well established guidelines for the safety operation of coal grinding equipment. These fall into two broad categories: (i) explosion prevention, and (ii) explosion protection. For prevention the best solution is to ensure that there is less than 12 per cent oxygen in the atmosphere. You cannot do that when cooler exhaust air is used for coal drying. As a general guideline drying with cooler exhaust air is suitable with direct firing systems. Other prevention measures are to ensure there are no fine coal dust accumulations in the system and no possible sources of ignition. These are determined by the design of the coal milling and storage system. With your non-inert coal grinding system you will have to have rigourous explosion protection designed into the equipment. The mill, raw coal feeder and ductwork must be capable to withstand a pressure of 9 bar. The dust filter, any cyclones and fine coal hoppers, must be fitted with explosion relief doors or rip-foil sides. Ducts entering these containers must be have explosion relief ahead of the container is they are longer than 5x their diameter. You can see that there is no simple answer to your question. A full inspection and audit would be required before anyone could certify that it is safe to grind the Indonesian coal in your system. I would recommend modifying the system to dry the coal with inert preheater exhaust gases. Regarding storage it is not desireable to store high volatile coal in large stockpiles. However, you will have to import large shipments to make it economic. The stockpiles need to be compacted to minimise air ingress into the piles. You should also limit the height of such piles. With 42 per cent volatiles the height of the piles should be limited to 4m
