A raw mill is the equipment used to grind raw materials into quot;rawmixquot; during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the efficiency of the whole

They are air swept mills, therefore has a higher drying capacity to handle an aggregate moisture of up to 20% in raw materials. Space needed for vertical mill is much less than a closed circuit ball mill of same capacity. As separator is integral part of the mill itself, the number of auxiliary equipments are less.
circuit of hydraulic circuit of raw mill. GRINDING TECHNOLOGY COURSEThe Cement Institute. Depending on the selected system the ball mill is in open or closed circuit (in most applications the ball mill is in closed circuit). Finish Grinding System. The ball mill is omitted and all grinding work is done in a more efficient comminution machine.
Preheater consists of 46 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 stagecyclones are commonly existing in cement plants.
The engineering team of A TEC has designed a special SPLASH BOX to avoid a poor degree of calcination of the raw material, high exit temperature at the preheater top stage and consequently higher specific energy consumption (kcal/ kg clinker) as well as poor clinker quality.

05/10/2020#0183;#32;Roller grinding mills and ball mills grind the mixture to a fine powder at the same time as drying it, before it is conveyed to the raw meal silos for further homogenisation. Step #4 The burning of the raw meal at approx. 1,450#176;C is carried out in Lepol or preheater kilns that work by varying methods, the main difference being in the preparation and preheating of the kiln feed.
