Ball charge optimization

Raw mill specific power 1st compartment. For the RM it is considered to have 40% – 45% of the total mill power consumption in the first compartment. Most common ball charges within the group . The following ball charges are the most common in our group and can be used as starting point to design a new ball charge. This approach is recommended ...

A scale-up and design basis of continuous tube mills in …

The mills were all multi compartment and the mill insides were protected by liners with lifters (the heights were between 30 mm and 55 mm). The Association asked cement industries to measure the operating conditions and to collect samples of feed and product (and those of classifier inlet and recovery as well for closed circuit) at steady ...

Optimization of a fully air-swept dry grinding cement raw …

The ball mill was simulated as a single compartment mill by eliminating the mill length of 2.935 m which was used in drying stage, such that the full length (L = 9.87 m) of the mill was used in grinding. Thus, drying of the raw meal outside the mill by an appropriate dryer was assumed.

Ball Mill

Tube mills having only one compartment and a charge of hard, screened ore particles as the grinding medium are known as pebble mills. They have the advantage over ball mills when iron contamination needs to be avoided. Since the weight of pebbles per unit volume is about 35–55% of that of steel balls, ...

Everything you need to know about clinker/cement Grinding

For the RM it is considered to have 40% – 45% of the total mill power consumption in the first compartment. For raw mills it is most common to use a ball charge with the coarse grading (up to 50% of 90 mm balls) – see table below for "coarse" grading. Cement Mill.

Application of TUSSIM with a variable Tromp curve for …

A single-compartment mill entails a pre-milled feed for proper operation, whereas a two-compartment mill yields a finer cement product than a three-compartment mill. Uniform mass distribution of balls led to slightly finer product than uniform surface area or number distributions, while the impact of a classifying liner was negligibly small. ...
