The grinding  theory. Though used different medium (steel ball and steel rod are contained in  ball mill and rod mill), the working theory of ball mill and rod mill are  similar. When the shell move, the medium in shell be raised and down which has  a impact on ore. Some medium may close to the tube wall of shell which can  grind the ore. After long time grinding, the material be grinded to the correct  size.

For details, the  grinding theory of ball mill and rod are different in many ways. For ball mill,  the grinding force of steel ball to ore is less than the impact, because the  contact area is small between balls and mineral. Thus, the throwing motion of  ball can produce a large impact, but it need a high rotate speed and has a  higher power consumption. But for rod mill, grinding effect is better which  need a lower rotate speed and has a lower power consumption.

Xinhai produce  all kind of ball mill and rod mill with high quality, you would interested in  them.

  How much does the Copper Ore Dressing Cost ?

  In a copper dressing plant, ore dressing cost contains many aspects, such as construction,  equipment purchasement, worker salary, maintenance and update consumable parts.  Just make the Dexing copper ore as a sample, its copper ore cost is calculated  from many aspects, except its construction, equipment purchase and salary cost,  its consumable parts updating and regent consumption has large percentage. Ore  character→mineral pressing flow sheet → equipment selection, as the  order, firstly we should analyze the ore character, metal ore include chalcopyrite,  secondary is bornite, malachite, chalcocite. Gangue mineral include dolomite, carbonation  dolomite, secondary is quartz, calcite and feldspar. Copper ore exists in dolomite,  carbonation dolomite, carbonation dolomite disseminated as massive, patchy,  scattered dots, oxidized ore exists in powdery and thin film. Chalcopyrite  particle size is 0.03~0.2mm, middle hardness, and its density is 2.85t/m³.

  What the Tailing Can Do for?

  In domestic, the typical features of the ore are poverty, fine  particles, and complex components. In our country, there are few ores can  achieve dissociation only by crushing process, but most of ores by crushing and  grinding process. Ball mill is a kind of significant machinery to make the ore  be dissociated. Choosing the ball mill and the grinding plant affects the production  index of the whole dressing plant.
