The VRM energy requirement was about 6 kW-h/t as compared to 13 kW-h/t for the ball mill, representing an energy savings of about 55%. Conjugate Anvil Hammer Mill (CAHM) is a novel technology that breaks particles under compression. Furthermore, innovations that significantly reduce energy consumption in any of these three main Typically, the specific energy necessary to reduce the feed material to the desired product size varies in the range of 5–50 kWh/t. Therefore, it is important to have a sound methodology for design and scale-up of ball mills from the energy efficiency and productivity points of view.Estimation of the Specific Energy Requirement for Size

The main equipment for grinding construction materials are ball-tube mills, which are actively used in industry and are constantly being improved. The main issue of improvement is to reduce the power consumption of a ball-tube mill with cross-longitudinal movement of the load. A comparative analysis and the possibility of using the knownThe design of ball mills was described back in the 18th century—and the principle of their operation has not changed; the only significant changes are the increased diameter and some new solutions for the mill’s drives introduced.
