Raw materials of the cement plant are mostly from open-pit mines, and the ore usually has a large particle size. In the preparation of cement raw materials, we first need to crush limestone, gypsum, clay, and other materials into a proper size to facilitate the subsequent transportation and storage and, at the same time, make full preparations for the next process (cement raw materials grinding). Therefore, as the first process of cement production, material crushing is particularly important in the design of a cement plant.
As a cement plant manufacturer, AGICO not only produces cement production lines and stone crushing plants, but also manufactures many cement equipment, such as a series of cement crushers required for cement raw material crushing: cone crusher, impact crusher, hammer crusher, jaw crusher, and four-roll crusher.
How To Select Cement Crusher Machines?
The following methods are usually used to crush materials: extrusion, cutting, and impact. In normal conditions, one crusher may use one or more methods to break materials, among which the extrusion principle has the lowest energy consumption and the least wear. While there are some other factors that need to be considered when we choose the crusher, such as material moisture content, hardness, abrasion, mechanical robustness, and operating costs.
Jaw Crusher & Cone Crusher. These two kinds of crushers crush the material by the principle of extrusion.
Hammer Crusher & Impact Crusher. These two crushers are based on the impact principle of material crushing, with coarse crushing, medium crushing, and fine crushing. Their main difference lies in the broken part. The former uses the hammerhead hinged on the rotor, while the latter uses the blow bar embedded on the rotor.
Roll Crusher is based on the principle of cutting and extrusion for material crushing.
1. The hard material with larger or medium-sized particle size is usually crushed by the extrusion or impact method. We usually adopt a jaw crusher, a roll crusher, etc.
2. Materials with strong abrasiveness are generally crushed by the extrusion method, and the surface of the grinding part should be smooth. But if the material is very difficult to break, it is necessary to consider a two-stage crushing system that takes a jaw crusher as the primary crushing equipment and a hammer crusher as the secondary crushing equipment.
3. Materials with weak abrasiveness are usually broken by impact or the grinding method. The crushing part should have sharp teeth.
4. The hard materials with smaller particle sizes are generally crushed by the extrusion or impact method. The surface of the crushing part is smooth and toothless, such as a roller crusher.
5. Materials with strong toughness are usually crushed by cutting or quick-hitting, such as a hammer crusher.
In a word, the choice of cement crusher should be based on a specific analysis of the specific situation. AGICO provides solution design and equipment customization services and can manufacture crusher machines according to the specific situation of the customer’s production line. Meanwhile, our efficient delivery, on-site installation, commissioning, and equipment operation training services will bring you a different purchasing experience.
