2014-5-17 Specific energy is a measure of process efficiency. It relates to the difficulty of machining a workpiece material. It also relates to wheel wear. For example, where the grinding power is 25 watts per cubic millimetre of material removed per second for a particular workpiece material, the specific energy is

In their studies on power consumption of fine grinding of corn and grain sorghum, Martin and Behnke [23] reported that high energy was consumed for fine grinding of material. Himmel et al. [24], Pfost and Headley [25], Fang et al. [26], Samson et al. [27], and
MoreThe basic grinding factors such as force ratio, specific material removal rate, maximum undeformed chip thickness, and specific grinding energy have been investigated and
More2018-6-5 The basic grinding factors such as force ratio, specific material removal rate, maximum undeformed chip thickness, and specific grinding energy have been investigated and discussed. The mathematical models containing linear terms and interactions of the first-order have been used to investigate the effect of the grinding parameters on the ...
More2013-12-18 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
MoreAbstract: An investigation was undertaken to explore the specific energy and material removal mechanisms involved in the grinding of cemented carbide with vacuum brazing diamond wheels. A mathematical model, relating to the grinding parameters such as wheel velocity, workpiece feedrate and depth of cut, was proposed to predict specific grinding ...
MoreGrinding energy provides a valuable measure of the ability of a grinding wheel to remove material. Grinding energy depends on grinding wheel sharpness and grindability of the workpiece material. Some work materials are much more difficult to grind than others. Grindability is a commonly used term to describe the ease of grinding a work material ...
MoreGrinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed

MoreRaw materials are used in many industrial technologies. The raw material frequently has to be prepared as an intermediate with an appropriate particle size distribution, which requires the use of grinding. In grinding processes, energy consumption is a very important profitability criterion for the applied particular size reduction .
MoreIt has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.
