raw material in cement plant

The most common raw rock types used in cement production are:

Limestone (supplies the bulk of the lime)

Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide)

Other supplementary materials such as sand, pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition

applications of crushed limestone

Limestone crusher in cement industry: limestone crusher is the most widely used limestone crushing plant. Limestone is the food and lifeline in cement production line. Limestone crusher resizes the materials into sand size products which will be processed into powder in the limestone grinding process.

limestone crushing plant

Limestone crusher for construction industry: limestone crushing plant processes limestone raw materials into sand product which can be used in construction. Limestone aggregate is the most important construction materials, widely used in road and building.

Limestone is easy to crush. For one thing, its hardness is very low (Mosh Hardness 4 to 5). A second is the low content of silicon. Therefore, we can crush limestone with a much lower cost. So, on the limestone crushing production line we can use jaw broken plus impact crusher crushing process solution, which get good stone tablets and wear parts can have a long life. Typically, it is normal for a jaw plate with one or two years service time.

We also need to consider another factor. Due to the relative ease of limestone crushing performance, impact crusher crushing process will produce more powder. If the customers don't have special requirements on stone's grain, you can use two-stage jaw crushers to reduce the proportion of powder, reducing investment costs at the same time.

Because the easily broken characteristic of limestone, we usually choose single crusher as the limestone crusher in cement industry. Using compound crusher as the primary limestone crushing plant, we can get final products with particle size between10 to 20 mm. so we can get the smallest possible size, regardless of the grain problem. At the same time, this approach will generate a lot of broken powder, mainly for the building stone quarry, which means less breakage issues.
