media charging process for cement mill

The aim of the IGF project 21791N is to better understand the influence of ceramic grinding media (balls) on the comminution process and the product quality during cement grinding in ball mills. The data will serve as a basis for designing and predicting the energy requirements and behaviour of grinding plants when using ceramic grinding media.

In the case of the semiautogenous mill, the comminution process is aided by a small grinding media charge. The diameter : length ratio of AEROFALL mills is 4 to 4.5; the ball charge can be up to 12 %. The material is discharged pneumatically and the finished material is collected in a filter or in a tailings separator and cyclones.

The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are …

The choice of grinding media The choice of grinding media will always depend on the material to be ground. You need to assess its granulometry and the grinding process. You also need to look at the relative importance of the wear mechanisms in the process.

The example in Table 1 considers Tetratex ePTFE filter media, manufactured solely by Donaldson Membranes, in a cement finish mill process utilising an estimated 10% increase in airflow. Where other system parameters are acceptable, the use of Tetratex could significantly reduce the cost/tonne of product and increase mill capacity.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
