Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Ball Charge Design & Management. Slegten Model. • Divides the mill into 3 parts. • Preparation in the 1st Compartment. • Same quantity of 80, 70, 60mm balls 16% of 60mm. • Addition of 90 mm. • Transition zone in the 2nd Compartment. • Same quantity of 50 and 40 mm balls. • Finishing zone in the 2nd Compartment.

3.3.1 Cement Mill. The approach is to use a ball charge as fine as possible in the 2 nd compartment for all cement types as long as the criteria for size reduction is met in chamber 1. For mills producing several types of cement, we optimize for the main type. It is recommended to start first with the coarse grading.

Ball Mill Ventilation. Objectives: Cement cooling. • The purpose of cooling is even more important. • when the inlet clinker is hot. • in a closed circuit without ventilated separator. • Ventilation cooling is always preferable to water spraying. in the mill. Ex: Cement grinding with specific energy of 32 kWh/t. 95% energy into heat.

Demerits: 1. High Energy Consumption: Ball mills often require high energy input for the grinding process, making them less energy-efficient compared to some other milling techniques. 2. Wear and Tear: The grinding media and liners experience wear, requiring regular maintenance and replacement. 3.

The material inlet angle dictates the material's entry direction into the reduction furnace. Fig. 14 illustrates that increasing the material inlet angle results in a gradual rise in turbulent kinetic energy in various areas, leading to field instability. The convergence of the material inlet, both below and above, induces vortex formation ...

For milling time, the ball milling process was interrupted at a regular interval of 10 h for powder extraction and characterization, up to a total milling time of 60 h. It is worth noting that a small ball (which weighs ~1 g) is removed at every 0.1 g of powder extraction to maintain the ball-to-powder ratio. 2.3. Materials characterization
