To save energy, modern cement plants preheat the meal before it enters the kiln. Rising more than 350 feet, hot exit gases from the kiln and clinker cooler combined with fuels such as ground coal, petcoke, natural gas, and recycled waste streams, heat the raw materials as they swirl through the cyclones.
Cement production line is the construction project to produce cement by a series of equipment. LVSSN group adopts advanced technology and equipment to improve the efficiency technical level advanced design ensure the economical investment for the cement production line.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill built to last, reliable and energyefficient is the optimum solution when it comes to performing several process steps in one unit.

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 is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The ATOX coal mill is suited for various installation types, whether inert or noninert, and direct or indirect firing systems. An inert system designed for indirect firing is the most common solution for cement plants. Equipped with the highefficiency RAKM dynamic separator, the ATOX coal mill will grind any type of coal to the required
