Indonesia Coal Milling Plant Design

Background

According to the recent statistics of Indonesia Ministry of Energy and Mines, the coal reserves in Indonesia are about 58 billion tons and the proven reserves of coal are about 19.3 billion tons. As we know, coal is important fuel. In this article, we focus on Indonesia coal milling plant design.

Indonesia Coal Milling Plant Design

Our engineer designed a complete coal milling plant for an Indonesian customer in 2012. This customer needed a 20tph coal grinding plant. After communication, we learned that his coal is in good quality with low sulphur but the moisture content is a little bit high. So our engineer designed a complete plant consists of a jaw crusher, a vibrating screen, a LM vertical grinding mill and several belt conveyors for him.

Machines In The Plant

For jaw crusher, our engineer recommended our PE250*400 jaw crusher for him. The capacity range of this jaw crusher is 5-20tph, totally suitable for the customer. For the vibrating screen, we suggested our 2YA1237 vibrating screen. For grinding mill, our engineer recommended our LM150M vertical grinding mill, which is particularly suitable for coal grinding. The capacity range of this mill is 16-22tph, suitable for the customer. Other reason for recommending this model is that this mill has dryer inside, which makes this mill ideal for the customer. As we said, the moisture of the coal is a little bit high.

Working Process

Firstly, jaw crusher will crush the coal into smaller particles. And then the coal particles will be sent to the vibrating screen for grading. The particles with required sizes will be conveyed to the grinding mill for grinding while others will be sent back to jaw crusher for re-crushing. The coal particles in the grinding mill will be ground into powder.

The customer was very pleased with this design. Of course, ZENITH can provide other types of crushers and grinding mills. Our engineer will recommend suitable type and model according to the requirements of the customers. So if you are also interested in coal grinding, feel free to contact us.
