### ROM ball mill design Grinding & Classification Circuits

Dear sir; I want to design the ROM ball mill (it's same of ball mill but it can accept the big size until 150mm): are there some process limitation for this technology? is it possible to design ROM ball mill (1 stage) from D80=100 mm to P80=120um? for the design is it possible to take

They tested the general effect of various circuit design and operating variables, including circulating load ratio. “All product size distributions had the same 80 percent passing size, and fresh feed rate was altered to give a range of circulating loads. It was shown that the ratio of the closed to open circuit feed rate, which may be taken as a measure of the increased efficiency of closed

Ball mill design is rather simple. This grinding equipment is a drum filled with metal or cast iron balls (grinding media). It is used mostly for production of bulk construction materials, paints, pyrotechnical devices, ceramics and in other industries. The ball mill patent was sealed more than 180 years ago. It is mentioned in "Industry and engineering" encyclopaedia dated 1896. This

The design of a ball mill can vary significantly depending on the size of the required mill, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the “lengthto- diameter” ratio, which frequently varies from 0.5 to 3.5.

For example, when 60% of the solids in a ball mill is coarse, then the coarse solids inventory * in the mill is 60%, and only 60% of the mill grinding volume and power is used for the grinding of coarse particles. The classification system efficiencyof the circuit is then only 60%. We can simply define "classification system efficiency" as the

Developments in iron ore comminution and classification technologies. A. Jankovic, in Iron Ore, 2015. 8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the
