Raw mill is also called cement raw mill similar to cement ball mill it is an important cement milling equipment used in the cement production process Raw mill is mainly used for grinding cement raw meal in the cement factory production process It is also suitable for metallurgical chemical electric power and other industrial mining enterprises to grind various ores and other grindable.
Cement is reclaimed by 3 screw conveyors which carry it to a one spout packing machine andor the optional bulkloading silo The container number 5 contains a one spout packing machine which is able to deliver two hundred 50kg cement bags every hour On the other side of the container the ball mill drive system is installed.
The grinding media balls in the ball mill are used in cement plant to help grind blocky or granular grindable materials produced in the cement manufacturing process so as to achieve the effect of grinding Vertical roller millVRM and clinker grinding mill and other cement grinding mill are also very common in cement plant.
Mills belong to a class of equipments that accomplish comminution of materials in the fine range There are two types of mills which are mostly used in cement plants for grinding raw mix viz Ball mills and VRM Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84 passing 90 microns.
In any cement grinding circuit it is necessary to grind clinker gypsum and sometimes other additives in the proportions required at a predetermined fineness The fineness is usually defined by the specific surface area of the cement measured in m178kg or cm178g Ball Mill Dust Collector.
Relation between Cir Load and mill discharge Fineness for raw grinding Mat circulating load factor is computed for rawmill and cementmill at a sep efficiency of 90 and 70 for target residue.
Cement Ball Mill is mainly used in grinding of cement finished product and materials also to the metallurgical chemical electricity and other industrial and can be used to open streams but also to the composition and the separator flow grinding circleCement ball mill has a strong adaptability of materials to production broken rate large easy to speed grinding fineness of the product and.
