Customer Introduction

At the end of year 2013, an Indonesia customer contacted SBM and said he wanted to grind his coal into 200mesh size. After communication, we learned that the sulphur content in his coal is quite low, but the moisture content is a little bit high. After communication, we learned about his requirements:

  • Raw material: coal
  • Moisture content: 12%
  • Capacity: 15tph
  • Max feed size: 100mm
  • Final products size: 200mesh
  • Application: power plant

Main Equipment

  • Coal crusher: PE250*400 jaw crusher
  • Coal grinding mill: LM130M vertical grinding mill
  • Bucket elevator
  • Vibrating feeder

Why Choose These Machines?

PE250*400 jaw crusher: as we can see, the raw coal size is 100mm, too large to be directly fed into the grinding mill for grinding. So we need to adopt a small jaw crusher to crush the raw coal into proper sizes. And considering from the requirements of the customer, PE250*400 jaw crusher is the proper choice.

LM130M vertical grinding mill: the engineer recommended LM130M vertical grinding mill for the customer is not only because its specifications are suitable for the all the requirements of the customer, but also because that this mill combines grinding, drying and classifying into one set. We do not need to equip an extra dryer in the coal powder milling plant. Because the moisture content of raw coal is a little bit high, so in order to get better performance, this mill is the ideal choice.

And here is the work process of 200mesh coal powder milling plant: raw coal—jaw crusher—bucket elevator—vibrating feeder—vertical grinding mill—200mesh coal powder.
