Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74, the product becomes coarser again. At this level, a drop in grinding efficiency occurs. Figure 7.
The working principle of the ball mill is as follows. In a continuously operating ball mill, the feed material copper ore passes through the central hole of one of the caps into the drum where it is exposed to the grinding media. The grinding of the material occurs during impact with the falling grinding balls and abrasion of the particles
Reducing the ball charge will reduce the grinding capacity, and the comment on installing a grate discharge is a good one as it will let ore out sooner, thus minimizing overgrinding, which will occur if the mill is temporally too big, or one chamber is too big in a multi chamber mill.
Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge. cascading for coarse to medium grinding or attrition for medium to fine grinding. In any case the design of a liner is a compromise between lifetime and grinding efficiency. Case study. Copper mining
This case study describes bearing damage detected through online measurements taken from a ball mill at the flotation plant of Asarel Medet AD in Bulgaria. Asarel Medet AD is among the largest Bulgarian mining companies for the extraction and enrichment of copper ores, located in the territory of Panagyurishte in the Pazardzhik district.
There is significant case study published regarding energy savings and cost efficiencies of the comminution process due to HPGR. Energy savings ranging from 10 to 50 per cent compared to grinding
The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 2075 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
Zijin Mining Group has chosen an FLSmidth gyratory crusher, SAG mill and ball mill for the Majdanpek mine, part of the Chinese mining companys majority owned Zijin Bor copper mine, in Serbia. The delivery of the equipment to Majdanpek, 180 km from Belgrade, is expected to occur between 12 and 18 months from now, with the project estimated to
In this context, a study was initiated to assess not only the performance of a Vertimill grinding circuit processing a copper concentrate to a particle size of 80 passing 17 m but also to provide Tasekos New Prosperity project specific design information for grinding to particle sizes below 80 passing 25 m.
Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11.The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
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.

No wear was found at the cage, outlet head and air intake spiral. Gap of outer cage wheel sealing 25 35 mm Gap of inner cage wheel sealing 10 30 mm
A descriptive iron ore case study will be presented illustrating the process steps and equipment design, and examples of potential applications in copper and gold ores.
The Planetary Mill PULVERISETTE 5 premium line with 2 working stations is the ideal mill for fast wet and dry grinding of hard, mediumhard, soft, brittle and moist samples as well as for
Case Study Aluminum Smelter Ball Mill. NZAS Aluminum Smelter extends ball mill life by 300 using MVS starter. Located on the Tiwai Peninsula, New Zealand Aluminum Smelters Limited NZAS is one of the worlds largest aluminum smelters.
The grinding media cost was reduced by the equivalent of 200,000 USDyear by switching to a lower cost Duromax cast grinding ball. The customer indicated that should the plant suffer a loss in copper recovery they would revert to the initial alloy.
5 The 24 x 39.5 Ball Mill The Copper Mountain ball mills are 7315 mm 24 feet in diameter and 12040 mm 39.5 feet long. They are overflow discharge ball mills with inside diameters of 7315 mm 24 feet and grinding
