Tertiary crushing is the final stage in the comminution process, where the product from the secondary crushing stage is further reduced in size to a finer product size. The purpose of tertiary crushing is to produce a high-quality end product that is suitable for use in various applications, such as concrete production or road construction.
Crushing. The quarry stone is delivered through chutes to the crushers, where it is reduced by crushing or pounding to chunks approximately 1 ½ inches in size. 4. Prehomogenization is the proportional mix of the different types of clay, limestones, or any other required material. 5. Raw material storage.
Concrete crushers are portable concrete crushers used on mining and construction job sites to break up large pieces of hard materials such as concrete, rocks, and minerals. ... concrete crushers are commonly used in the primary and secondary stations of the crushing process. If you look at a cross section of a concrete crusher, you'll see ...
1. Mining and Crushing. The process of making cement begins with mining, where raw materials are extracted from quarries. Huge machines called excavators dig the limestone out of the earth. The extracted limestone is then taken through a crushing plant, which reduces the size to smaller pieces of about 5 inches in size.
The desired raw mix of crushed raw material and the additional components required for the type of cement, e.g. silica sand and iron ore, is prepared using metering devices. Roller grinding mills and ball mills grind the mixture to a fine powder at the same time as drying it, before it is conveyed to the raw meal silos for further homogenisation.
