This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite.
The cost of coal and fuel is always on the rise and most plants us a big variety of fuels and waste materials for the kiln which makes it even harder to control the burning process. Continuous gas analyzers at critical locations can contribute massively to the optimization of the cement process and significantly reduce the production costs.

Cyclone preheater, also known as suspension preheater, is the main cement equipment commonly used in the new dry process cement production line. It is the main gas-solid reaction unit of the cement raw meal pre-decomposition system, which makes full use of the high-temperature exhaust gas discharged from the kiln tail and the high-temperature flue gas …
Coal water slurry ball mill (CWS ball mill) is the key equipment for coal water slurry fuel production, which is commonly used in coal water slurry power plant Coal water slurry ball mill is grinding equipment specially used for coal water slurry production Its specifications, structure and working conditions must meet the requirements of coal water slurry production scale,
The raw is then fed to the coal mill VRM via weigh feeder, drag chain and screw conveyer. Important Parameters Of Coal: • Residue on 90 micron=18-20% • Residue on 212micron=0.4-1% • Moisture =1.5% • Volatile Matter =20-30% • Ash content =28-32% Coal Mill:Coal Mill is an important integral part of cement plant.
So we usually use coal mill in cement plant, coal mill in power plant, and coal mill in thermal power plant. The working of vertical coal mill has higher accuracy, so it is more conducive to the fine grinding of materials and the adjustment of granularity.
A comprehensive cement plant audit will help you successfully optimise processes and ensure your production lives up to its true potential. What we offer. Evaluate total plant performance – from quarry to cement silo. You might seek an audit to help you with decreasing production or insufficient product quality.

Fly Ash Processing Plant - Cement Equipment . Fly Ash Processing Plant - Cement Equipment Manufacturing - AGICO. Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged from coal-fired power plants. Its annual output is large, which has great harm to the environment and human health.
Plant staff in the cement industry need to focus on producing cement. Fire and explosion protection for coal grinding is a highly specialised field. You cannot expect that plant staff recognise flaws in the system that has been put in front of them, normally with no or very little input from their end.
Coal Mill Coal Mill In Cement Plant AGICO Cement . The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination.

The results of the analysis show that the raw mill and the coal mill are critical subsystems of a cement plant from a reliability point of view, whereas the kiln is a critical subsystem from an availability point of view. The analysis shows that the repair time of the cement mill should be reduced for improving the availability of the cement plant.
