Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget. Overall energy use and media

The Global Mining Guidelines Group (GMG) recently released revised versions of two widely used guidelines in mineral processing. The new publications include a revision of The Morrell Method to Determine the Efficiency of Industrial Grinding Circuits, which was originally published in 2016; and Determining the Bond Efficiency of Industrial Grinding Circuits.

SMC Data Processing. The results from conducting the SMC Test® are used to determine the drop-weight index (DWi) which is a measure of the strength of the rock as well as the comminution indices Mia, Mih and Mic. In conjunction with the Bond ball mill work index they can be used to accurately predict the overall specific energy requirements of
The evaluation of the experimental result is completed following the “standard” of the Bond procedure, viz. the Bond work index (kWh/t) is determined using by the following equation: (3) BWI = 4.9 x max 0, 23 G 0, 82 1 x 80 '' − 1 X 80 '' where x max is the closing sieve size in μm; G is the net grams of sieve undersize per mill revolution; x 80 is the 80% passing size of the product in

A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 ( JKMRC CO., 2006 ). This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the
