Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.
Prehomogenization. In past cases, where the main component of the cement raw material (usually limestone), showed con siderable fluctuations in the CaC03-content, and as long as relatively low quantities of raw materials were processed in cement plants, selective quarrying was applied, to reduce to some extent fluctuations in the limestone's chemistry.
Cement conveyor refers to a belt conveyor in cement plant, which is necessary accessory equipment in the cement production line.. A belt conveyor is a kind of material handling equipment with strong adaptability, applied for conveying bulk density less than 1.67t / m³, it is mostly used for powder, granular, small lump materials, and bagged materials, such …

An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
For drying the wet raw material it is necessary that prior to the mill start up the grinding plant is.heated for some time.Otherwise the cold grinding plant would take away too much heat from the drying process and the finish product would not be dry – handling problems in the meal transport and silo extraction would follow.
Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. Induced draft fans: Induced draft fans ...
When envisioning the cement plant of the future, it is important to understand the reference for a typical plant today. Our reference plant is a five-stage preheater-calciner kiln with a vertical raw mill and two cement ball mills. It has an annual production capacity of one million metric tons of cement and produces several types of …
