Dry Type Cement Ball Mill Equipment for Ferrous and Non-ferrous Metal Mine
Introduction of Dry Type Cement Ball Mill
1. Ball mill is the key equipment for secondary grinding after crushing.
2. Be suitable for grinding all kinds of ores and other materials.
3. Suitable for wet grinding and dry grinding.
4. Widely applied in many industries, such as ferrous & non-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry, etc.
5. According to different discharging ways, it can be divided into grate type and overflow type, or wet type and dry type.
Features & Advantages of Dry Type Cement Ball Mill
1. High-efficiency. Our ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it can save energy by 10-20%.
2. Simple structure, easy maintenance. Ball mill is mainly composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). Convenient installation and debugging , easy to operate.
3. High processing capacity, obvious continuous operation advantages. The capacity can get 4.6-260 t/h.
4. Wide-range usage. Ball mill is an old grinding equipment in market, the technology is mature and it is operated steadily.
Working principle of cement grinding plant
This grinding ball mill is horizontal type and tubular running device, has two warehouses. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. In this warehouse , there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force ,at this time , the steel ball is carried to some height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board and the end products are completed.
