What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points.
Under ideal working conditions, Raymond Mill consumes less energy than other ordinary grinding mills. For example, the MTM Medium-speed Grinding Mill only consumes 1.02kW/h when yielding a ton of materials and 1.48kW/h when feeding a ton of materials. Its electricity consumption is lower than that of ball mill at the same level by over 60%.
The main structure of the ball mill includes a solid cylinder, which contains grinding balls of different materials and sizes. The motor and transmission system is used to drive the rotation of the cylinder, while the feeding and discharging system is responsible for the introduction of raw materials and the discharge of finished products.
This paper demonstrates the feasibility of using a ceramic medium stirring mill to reduce the energy consumption of grinding operations through an industrial verification experiment. Compared with the original two-stage ball milling process, the cost of grinding power consumption is significantly reduced by about 50.16%, which provides …
