Hongcheng Grinding Mill-Realize Efficient Utilization of Anthracite


Release date: 1970-01-01 08:00:00

After years of researching, Guilin Hongcheng discovered that, there are several conditions for anthracite application:

1. The coal powder should be in required fineness to ensure flame formation.
2. Stable and balanced coal powder feeding.
3. Burner should have enough and adjustable driving force.
4. There must be circulating air in the burner.
5. Use soft coal or fuel oil to assist combustion.

Modern burners are equipped in new dry process cement production lines, the new equipment has flame adjusting device, anthracite can be burned without problems.

The burner will not only transport and separate coal powder, the main purpose is to keep a suitable air flow. The flame length is important for dry kiln. If the flame is too short, the heat will only be released in small volume, the temperature will be high in some parts. But if the flame is too long, the temperature will be low. The flame length can be controlled with the burner driving force.

A simple way to keep a same flame length is to grind the anthracite into finer powder. Engineers of Guilin Hongcheng researched and developed the grinding mills, and finally created anthracite Raymond mill, ultra-fine mill and vertical mill equipment, the equipment can produce 80-1500 mesh coal powder to full fill different requirements.
