Tumbling Mill Grinding Devices
The various mining machine including grinding devices used in the industry are distinguished in terms of the manner by which energy is introduced into the system and in terms of capacity and particle transport into and out of the mill. Each device is characterized with respect to particle size range, design relationships, wear, and efficiency of energy utilization. For some grinding devices, well-defined design relationships have not been established, and in these cases detailed data on typical installations are given when available. Similarly, wear data for some grinding devices are not always available, especially for the more recently developed mills that have not been used extensively on an industrial scale. In addition, the wear characterization is difficult to generalize because it is highly dependent both on the nature of the feed and the materials of construction. The efficiency characterization is the free-crushing efficiency and represents that portion of the total energ...
