Coal Mill In Coal Powder Preparation Process. Coal mill is the main equipment in the pulverized coal preparation process.Because calcining top-grade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value …

Depending on the manufacturer's process, the grinding is done wet, dry, or semi-dry. In vertical shaft ball mills, 65% of the particles are smaller than 45 microns, and the balls used are around 12mm in size. The rotational speed can vary between 60 – 80 RPM. A typical ball mill can generate 3500 tons of cement per hour.

The first plant was commissioned at Virudhunagar and production began the very next year. Initial manufacturing used the wet process technology but by the 1970s, the plant switched over to the more efficient dry process. A natural expansion was into cement products including fibre cement sheets and boards with Ramco Industries.

The Cement Manufacturing Process. The production of cement involves a series of steps that transform raw materials into the final product. The process begins with the crushing and grinding of raw materials, followed by the formation of clinker, and concludes with the grinding and mixing of clinker to produce cement.

In this kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water.

There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.
