a)Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, andestablished empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the …Get a Quote
The main function of the steelballin theball millis to impact crush the material and also play a certaingrindingeffect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects thegrinding efficiency, and ultimately affects the output of theball mill.Get Price

Thegrinding efficiencyofball millis low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve thegrinding efficiencyofball millis an important problem.Get Price
Theball millis a tumblingmillthat uses steel balls as thegrindingmedia. 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 minimizeballcoating, or slurry containing 20–40% water by weight.Get Price
There are many factors affect thegrinding efficiencyofball mill. Many factors can be judged as qualitative analysis, which are difficult to make quantitative analysis. Therefore, theball milloperator must do a comprehensive analysis according to the actual production situation and the result of the qualitative analysis, thus drawing the ...Get Price

Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
