In general, Portland cement is the main production of cement industry. Portland cement is kind of meticulous powder, usually gray, which consists of calcium (from limestone), silicate, aluminate (clay) and ferrite. Limestone is the main raw material of cement production; most factories are located in the vicinity of limestone quarries in order to minimize transportation costs.
Cement Crushing Equipment
Usually we extract raw materials (limestone, shale, silica and pyrite) by blasting or by using cut-off equipment. Raw materials are sent to the crusher to be crushed or hammered into fragments. Usually Primary Crusher is Jaw Crusher while Cone Crusher and Impact Crusher works as secondary crusher.
Cement Mill
In the Raw Mill plant, we use vertical grinding mill and Ball Mill for cement further grinding. At this stage, Vertical Mill works by using the pressure of cylinder leakage to break the materials; ball mill is dependent on the steel ball grinding upon materials. Grinding Equipment works with higher capacity and saves energy greatly by using an electrical automation system which optimizes the grinding process.
Apart in the Raw Mill plant, ball mill is also widely applied in the clinker grinding process. Here the cement clinker is grinded into fine powder together with other raw materials, such as gypsum.
Primary crusher:
For cement primary crushing, we recommend Jaw Crusher to you. With simple structure and high quality, Jaw Crusher works with higher capacity and lower cost.
Secondary crusher:
For cement secondary crushing, you can choose CS Series Cone Crusher or Impact Crusher. Although their working principle is different, both the crushers are widely applied as secondary crushing equipment. You can choose right one according to your requirement.

To answer your question, the main production of the cement industry is Portland cement, which is a meticulous gray powder consisting of calcium, silicate, aluminate, and ferrite. The main raw material for cement production is limestone, so most cement factories are located near limestone quarries to minimize transportation costs.
To produce cement, the raw materials (limestone, shale, silica, and pyrite) are extracted by blasting or using cut-off equipment. These raw materials are then sent to a crusher to be crushed into fragments. The primary crusher used in this process is typically a jaw crusher, while cone crushers and impact crushers can be used as secondary crushers.
After the raw materials are crushed, they are further ground in the raw mill plant. Vertical grinding mills and ball mills are commonly used for this purpose. The vertical mill uses cylinder pressure to break the materials, while the ball mill relies on steel balls for grinding. Grinding equipment in the cement mill works with higher capacity and energy savings through the use of an electrical automation system that optimizes the grinding process.
In addition to the raw mill plant, ball mills are also used in the clinker grinding process. Cement clinker, along with other raw materials like gypsum, is grinded into a fine powder in this stage.
For cement primary crushing, a jaw crusher is recommended due to its simple structure, high quality, higher capacity, and lower cost.
For cement secondary crushing, CS Series Cone Crusher or Impact Crusher can be chosen. Both crushers are widely used as secondary crushing equipment, and you can select the appropriate one based on your specific requirements.
