1. Company Profile:
Vikram Cement Limited has an annual capacity of 18.2 million tones. It manufactures and markets Ordinary Portland Cement, Portland Blast Furnace Slag Cement and Portland Pozzalana Cement. It also manufactures ready mix concrete (RMC). Vikram Cement Limited has five integrated plants, six grinding units and three terminals — two in India and one in Sri Lanka. Vikram Cement is the country’s largest exporter of cement clinker. The export markets span countries around the Indian Ocean, Africa, Europe and the Middle East.

One of India’s mega national & multinational group. Produces aluminum, copper, cement, viscose, staple fiber, carbon black, fertilizer, chemicals, iron,etc. World leader in production of viscose and staple fiber. 40 companies, 18 countries. The group has 72,000 employees -7000,000 shareholders.

Established in 1985 at KHOR, district NEEMUCH, M.P. 3 units and 2 mines. Largest single location plant in the country.

5. Rotary Kiln Process
Rotary kiln process is adoptable in large cement plant. The steps involved in the process are: 1. Mixing 2. Burning 3. Grinding 4. Packing.

6. 1. Mixing Dry Process:
The calcareous and argillaceous materials are crushed and powdered separately. The powdered materials are mixed in proper portions to get dry “raw mix”. It is kept ready and stored, in storage bins (silos) and then fed into rotary kiln for burning. Wet Process: The calcareous materials are crushed, powdered and stored in silos. The argillaceous material is mixed with water in wash mills. The powdered lime stone and wet clay are led to grinding mills in proper proportion. Here they are mixed to form a paste called slurry’ containing nearly 4O% water. Its composition is adjusted and sent for burning process.

7. 2. Burning Process
(a) Drying Zone: it is upper part of rotary kiln, where temperature is around 100—400°C Water in the slurry gets evaporated here. (b) Calcining Zone: It is at the central part of kiln. The lime stone of “dry mix” or “slurry” undergoes decomposition at a temperature of 1000°C. (c) Burning Zone: It is the hottest zone. Temperature is about 1600°C. Here the mixture melts and forms clinkers (Small, round. grayish masses).

8. From the rotary kiln we get clinkers. These clinkers after cooling are carried to ball mills. It is mixed with 2—3% gypsum and grinded in ball mills. Gypsum increases the initial setting period of cement. 4. Packing The ground fine power of cement is stored in silos and is then packed into 50 kg bags.
