In a dry cement manufacturing process, dry raw mix contains less than 20% moisture by mass. However, in a wet process water is added to the raw mix to form slurry and then is transported to the kiln [11]. Raw meal or blended raw materials are fed into the upper end of the pre-heater tower and then passed through the end of the rotary Kiln.
Less Wear Protection in Cement Production All sections of cement plants are at risk with regard to wear. This covers the raw material storage and raw material processing. It includes coal pulverizing and injection into the rotary kiln. Furthermore, clinker handling and clinker grinding as well as handling of additives and cement are

A raw mill is the equipment used to grind raw materials into "raw mix" during the manufacture of cement. Dry raw mills are the normal technology installed today, allowing minimization of energy consumption and CO2 emissions. Process of raw mill in grinding of raw material and silo storage 1. Transporting crushed raw material to raw mill
introducing alternative fuels and raw materials into a standard cement production process, rather than using conventional fuels and raw materials. A cement kiln producing clinker (the main constituent of cement), is by its nature an efficient tool for the recovery of minerals and energy from waste. Below are some reasons why.

Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions
processing units are crushers unit, raw mill, homogenizing plant, kiln system, cement mill and packing plant. Here, dry production process is used because energy consumption is less and running cost is also lower compared to other process. The raw materials used are in the following compositions; limestone 95-97% and laterite 3-5%.
