What Is Raw Mill In Cement Line

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part ,discharging part ,rotating part ,transmission part (reducer,samll transmission gear ,motor,electric control) etc.

Raw mill is also called raw material mill, which is the essential equipment in the production process of cement. It has large application such as raw mill in cement plant, building materials, metallurgy, electric power and chemical industry, which is mainly used for the grinding as well as drying of cement raw materials and other materials.

Raw Grinding Plant. 1. Wet grinding mills such as ball mills operating either in close or in open circuit. These are also called slurry mills which are used in both wet process as well as semi - wet process plants. 2. Dry grinding mills, operating only in closed circuit, are used in dry and semi dry process cement plants.

In this unit, the proportioned raw materials are being ground to the size of (10% residual on 90 μm sieve) by closed circuit ball mill in line 1 and Vertical Roller Mill (VRM) in Line 2. While grinding; the raw materials are being dried from 4% moisture content to <1% using the excess hot gas emitted from pyrporocessing system.

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime,

Cement production line,Cement plant,Cement making machine Cement production line is used to produce cement. It consists of a series of cement equipment: jaw crusher, cone crusher, raw mill, preheater, rotary kiln and cement

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

A large cement factory as an example, according to the requirements of process and control parameters of production line of raw mill, this paper researches and designs the automatic control system of cement raw mill production line based on PCS7 and PROFIBUS. The design of the whole system consists of three levels: field layer, control layer and operation layer which

22-01-2016· Raw Mill Exhaust Fans. Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along,

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.

In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, more than 80% of raw material is limestone.

Preheater consists of 4-6 low pressure cyclones one over the other. Number of cyclones depends on the natural humidity (moisture) in raw materials, in other words the drying capacity required to dry out raw materials in raw mill. Five stage-cyclones are commonly existing in cement plants.

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime,
