Fote - Model PE -Ball Mill

Ball mill is one of the mostly used grinding equipment with high efficiency. It is also one of the most ancient mining machines in the world, while the efficient ball mill was created until the industrial revolution and the invention of steam power.

Ball mill is usually classified based on different aspects:

• Working method: √ dry grinding ball mill; √ wet grinding ball mill
• Discharging methods: √ grate discharge ball mill; √ overflow discharge ball mill

Usually, investors are hesitated to choose ball mills of dry grinding or wet grinding. Here are some tips.

Wet grinding is more used than dry grinding to grind raw materials. Most of the grindable metallic ore and nonmetallic ore can be processed by wet grinding if it doesn`t react to water or the reaction influences the finished product quality.

These materials include copper ore, iron ore, gold ore, molybdenum ore, phosphate ore, feldspar ore, fluorite ore, etc.

While other materials like cement, marble and other building aggregates that react to water and will produce other kind of materials only need dry grinding. If the finished product is required to be stored and sold as powder, dry grinding is also the better choice.

Sometimes, we also differ ball mills by the materials processed. For example, Fote Machinery has the following kinds of ball mills for sale, gold ore ball mill, black manganese ore ball mill, nickel ore ball mill, tin ore ball mill, copper ore ball mill, garnet ball mill, andalusite ball mill, aluminum gray ball mill, molybdenum ore ball mill, fluorite ball mill and so on.

Ball mill is extensively used in the production of cement, silicate, refractory materials, chemical products, black and nonferrous metal ore dressing, glass ceramics and other industrial products. In recent years, it is also used for artificial sand making in new building materials production.

All kinds of ore and other grindable materials process can be completed by ball mill for dry or wet grinding. Grinding of ball mill meets the high requirements for uniformity pf discharged products.

There are some examples of various ball mills used in different industrial fields.

Cement ball mill

Cement ball mill is also shortened as cement mill. It is the main equipment in cement industry with high grinding efficiency, capacity and low energy consumption. Cement mill has superiority in grinding slag cement.

Coal ball mill

Coal ball mill is also one kind of ball mill that used to mill raw coal. Usually, to be simplified, we call it coal mill. To improve the burning efficiency, coal need to be ground by coal mill and then used in the pulverized coal-fired boiler. And to prevent casting from burning on or to decrease the surface roughness, high-quality coal dust produced by coal mill is added in the iron casting process.

• Main bearing performs well
  The traditional sliding bearing is replaced by large-diameter double-row adjustable roller bearing. This has reduced friction and lowered the energy consumption. It is easier to start the ball mill.
• Simple structure and stable operation
  There are two kinds of feeding device, combined feeder and drum-shaped feeder. They are installed separately, which is structured simpler. That there is no inertia impact makes ball mill perform more stable and has reduced the maintenance time as well as improved the efficiency.
• High anti-bending strength of gears
  Profile shifted gear is adopted by the new type of ball mill to avoid undercutting. And the anti-bending strength is improved greatly by over one time.
• Long bearing life
  The hollow shaft diameter of ball mill rolling bearing is enlarged, which increases the radial distance between the rolling bearing and the feeding and discharging screw barrel. This plays a certain role of heat insulation and cooling and extends the service life of the bearing.
