Milling Ball Mill

2.The intermittent ball mill can not continuous operation, at the same specification, its output is lower.The feeding and discharging time is set according to the characteristics of the grinding material.The intermittent ball mill is suitable for the mixing and grinding of materials, lower power consumption.Many ball mill has been transformed into continuous, so users do not have to worry about the production output problem.

Ball mill is the key equipment when the crushed materials need to be ground.Rod mill is called rod mill because the grinding medium in the barrel is steel rod.

Ball mills characterized by high energy consumption.When the mill idles, the energy consumption is approximately equal to the energy consumption with full mill capacity.Therefore, the work of the mill with partial load conditions is unprofitable.Energy consumption for ball mills is a function of many factors: the physical properties of the ground material its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc.Ball mills have low efficiency no more than 15%.Energy is mainly consumed on the wear of grinding balls and mill housing, friction; heating the material etc.

Ball mill has a strong adaptation ofmaterial, and it is suitable for grinding hard materials, such as slag,iron ore, copper ore, etc.

cement ball mill advantages 1.It has strong adaptability to materials, continuous production and large processing capacity.The equipment has stable performance, is convenient for large-scale production, and meets the needs of large-scale production of modern enterprises.2.The crushing ratio is large, the feeding size can reach 50 mm, the discharging particle size can be controlled, and the particle quality is good.3.Cement dry-type ball mill is mainly used for grinding raw materials and clinker (finished products and raw materials) in cement plant, and also for grinding various ores and other grindable materials in metallurgy, chemical industry, electric power and other industrial and mining enterprises.It can be used for open flow grinding and circular flow grinding composed of powder concentrator.4.The structure is reasonable, firm and can be operated under negative pressure.Cement dry ball mill has good sealing performance, environmental protection, simple maintenance, safe and reliable operation.disadvantages but at present, the overall efficiency of cement dry-type ball mill grinding is low and energy consumption is large.Although the rolling bearing transmission mode is used now, the cement mill process is still the most power consuming part of the enterprise.Moreover, the cement dry-type ball mill is generally medium and long grinding, with large investment and high cost.

On the other hand, there are also many disadvantages of ball mill; experts have been engaged in improving and overcoming those demerits several years before.

Kin mining recently transported a 150-tonne, 2.5mw, ball mill 60km, or two hours, from murrin murrin to its cardinia hub, where it will process gold for its 55,000oz a year leonora gold project.The second-hand ball mill will cost $900,000 to refurbish and be added to the lawlers processing plant, to be delivered in the coming months from gold fields operations near leinster, 130km away.

Ball mill works on impact principle that is size reduction is done by the impact.It contains a hollow cylinder shell that rotates around its axis and is partially filled with the balls.The ball mill may be operated in a batch or continuous fashion and wet or dry.

Each machine, each type has its certain rotary speed when it was be designed.As all we known high speed will have high capacity.But control it to be some certain is very important.High speed, intensified campaign, also the raw material has its own energy, so the over crushing will be occurred in the grinding.Taking ball mill as an example, type 1224.As we all known that its rotary speed is 27-34 r/min, if we increase the speed to the 36 r/m, the capacity will be get by 4.2%.In this condition, capacity of the size below 5mm will increase from 11% to 15%, and the metal will be 4% to 5.2%.

Vancouver, bc--(marketwired - june 15, 2015) - endeavour silver corp.(edr.To) (exk) announces that the 1,000 tonne per day (tpd) ball mill at the 1,600 tpd bolaitos mine was repaired earlier than expected and plant operations returned to normal last friday, june 12.No material impact on production is anticipated from the mill downtime as the mine continued to produce ore to the stockpile.
