The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
The ball mill will be m x m and contain a 35% ball charge. The final product will be 80% minus 75 microns. This grinding mill can process up to 762 tph of ore, and will be used in closed circuit with a battery of 84cm hydrocyclones. After grinding (SAG and ball mill), the ore .
Heibei 5000 t/d Iron Ore Beneficiation Project. The qualified iron concentrate of this project was obtained with Xinhai round vibrating screen Xinhai magnetic separator. Oversize middlings were sent to closedcircuit grinding system (including Xinhai wet grid type ball mill and hydrocyclone) for fine grinding.
After classifying, the parts whose size below the mesh size will be transferred away as final products, while the other parts will return to cone crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement. smaller crushed iron ore is fed to ball mill for grinding.

Grinding systems are either ''open circuit'' or ''closed circuit''. In an open circuit system, the feeding rate of clinker is adjusted to achieve the desired granularity of the product at the mill exit. In a closed circuit system, coarse particles are separated from the finer product and returned for a further grinding.
The former is equipped with a reverseconfigured ball mill closed grinding circuit, while the latter is equipped with ball mills under a direct closed circuit. The study consisted of laboratory jar tests, as well as comparisons between historical data obtained for both industrial plants. ... Keywords: iron ore, grinding, classification. RESUMO.

The pellets produced by Minnesota taconite companies generally contain between and percent silica. These silica levels were established initially by the concentratability of the ore, that is, its response to closed circuit ball mill grinding and magnetic concentration.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
