    The specific selection function effect on clinker grinding

    g the specific energy is 40 kWht using 20 mm size balls. The created specific surface is influenced by the ball size. The curves diverge at different initial specific breakage rate. For a given specific energy consumption the Blaine specific surface and the energy efficiency are greater with the 10 mm balls than with the 20 mm balls.

    Best energy consumption International Cement Review

    Feb 16 2015 Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans with pressure drops of 100mbar not uncommon with high nozzle ring velocities 70ms and internal mill.

    The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the specific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy.

    Feb 08 2021 Abstract Ball drum mills BDM are one of the main types of coal-grinding equipment in Russia. A significant drawback of BDM is high power consumption a significant part of the TPPs own needs. With a huge scale of production reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and.

    Abstract. A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function which calculates the particle breakage index t according to the size-specific energy and then calculates the full product size distribution using the t-t relationships and the mass-size balance approach.
