New Ball Mill
The ball mill is widely used to grind various medium-hard ores and other materials in mining, building materials, chemical industries, etc. The ball mill can be divided into dry type and wet type according to the milling method; grid type and overflow type or center-discharge and side-discharge type according to the ways of discharge; bearing-mill and bearing pad mill according to the different methods of supporting; rim drive and center drive according to the different ways of transmission. The large mill with diameter above 3 meters is especially configured with jack-up devices for easy maintenance; the dynamical pressure bearing and the static pressure bearing can operate stably. Slow rotation is convenient for overhaul and start; the oil sprayer lubrication device can make big and small gears reliable. The main motor of large mill is high pressure asynchronous motor or synchronous motor, which should be notified in the orders.
The machine is composed by feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The rotation big gearwheel is made by cast hobbling processing and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.

Our company can design all kinds of mineral processing flowsheets by the customers’ need. We generally adopt the physical mineral processing technology, which can produce high grade ore and high recovery rate in separating ores through practice. For example, red iron tailings and brown iron tailings with 20% iron can be processed into 57-59 grades iron ores with 65% recovery rate; we can separate the copper and the iron in copper slag with 36% iron and 4%-6% copper,and get 18-20 grade copper and 57-59 grades iron, and the recovery rate can be reached into 55%; To extract copper from the copper oxide containing ores, the leaching process is adopted, which can reach 22.4 grades copper. Our mineral process, simple and low cost, will be your best choice
