Achievement of High Energy Efficiency in Grinding Mills
2018220 The relative ‘efficiency’ of horizontal grinding mills compared to other comminution equipment is often debated, and efforts to improve the energy efficiency of these mills is an ongoing area of attention for process engineers. The discharge arrangement design affects the material transport characteristics within a horizontal grinding mill.

20191111 Therefore millers do their best to obtain high efficiency. Raw material, equipment and production flow are the key factors affecting the flour yield. Grain characteristics such as moisture content, environmental characteristics such as temperature and humidity in the mill and the level of experience of the miller are other factors affecting the yield.

200631 The specific energy of grinding is the energy input into the mill related to the mass of material m p. During the tests, the gross torque T and the rotational speed N were measured at the shaft. Considering the torque of the empty mill T o (which represents bearings losses, etc.) and the grinding time t, the specific energy E m can be determined by Eq.

200961 At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases. The practical limit to ball mill product fineness is considered to be 40–45 μm (Gao and Weller, 1994). Although ball mills can still be found in the regrind circuits in a number of mineral processing plants, their energy consumption is high, and size reduction efficiency is low.

Two of the most popular methods for estimating grinding energy requirements are the Bond operating work index (OWi) and the Morrell specific comminution energy method. Both relate the comminution energy to the reduction in the 80 th percent passing size of the feed and product streams (F 80 and P 80). An important condition that needs to be met for using the Bond formula is that the distributions should
