Volume 3, Issue 5, November 2013 388 hot-air furnace may be used to supply this heat, but usually hot waste gases from the kiln are used. For this reason, the raw mill is usually placed close to the kiln preheater. Ball mill is used in cement industry. After the dry chamber material enters the 1st grinding chamber. 1st grinding chamber:
Our OK Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK Mill is the natural choice for .
The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. Coal mill is major equipment of cement plant and used for drying and grinding coal.
The EO system was first started up, together with ABB experts, at Adana Cement on 11 May 2009 for process optimisation of clinker production line 4, which has an average capacity of 4500 tpd, including the control of the rotary kiln, calciner and clinker cooler. In a second step the raw mill of line 4 and coal mill 2 were included in the EO system.

Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout, as well as tramp metal detectors to protect equipment and keep the operation running smoothly. The Cement Manufacturing Process flow chart sums up where in the process each type of technology is making a difference. NOTE:
1 Introduction. Two mill systems are employed for most coal grinding applications in the cement industry. These are, on the one hand, vertical roller mills (VRM) that have achieved a share of almost 90 % and, on the other hand, ball mills whose share decreased to just over 10 %.
With any industrial activity, generation of waste and by-products is expected. In the case of cement manufacturing, the associated process leads to pollution in the following ways: • Dust generation in specific sections of cement plants (crushers, raw mill, coal mill, kiln, clinker cooler, cement mill) •
