Jul 31, 2014 The size reduction takes place in a two- compartment tube mill; the first compartment of the mill is shorter than the second compartment. The coarse clinker is ground in the first compartment where larger balls (80, 60, 50 mm) are used and the fine grinding is done in the second compartment where smaller balls (below 25 mm) are used.
On the other hand, portland cement is an artificial mixture of raw materials, has a calcination at a temperature above 2,000 degrees Fahrenheit, and purer raw materials were used than necessary for natural cements. The raw materials used in the manufacturing of portland cement at this time were cement rock, limestone, shale, and coal.
Jun 07, 2021 For the cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Optimization of Cement Grinding Operation in Ball Mills. The air required for classification is provided by another fan.

Wear-resistant liners protect the mill shell while providing lift to the ball charge. 4 Liners will also provide a classification of the ball charge, primarily in the second compartment to promote classification of ball sizes with the larger balls at the back and the smaller balls at the front. 4 With improvements in liner material such as high ...
The coarse clinker is ground in the first at low pressure drop across the mill. Also the in- and outlet as compartment where larger balls (80, 60, 50mm) are used and well as the diaphragm were redesigned. the fine grinding is done in the second compartment where smaller balls (below 25mm) are used.
