The effect of mill speed on kinetic breakage parameters of …

In this study, the effect of mill speed was investigated on the limestone and the clinker samples of Göltaş Cement Factory (Isparta, Turkey) at batch grinding conditions based on a kinetic model. For this purpose, first, six different monosize fractions were carried out between 0.850 and 0.106 mm formed by a two-sieve series.

Cement mill

A cement mill (or finish mill in North American usage[1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Chapter 18. Feed Milling Processes

Sometimes the shaft is hollow and liquids are forced through holes in the paddles in a spray effect. Some models have a shaft speed of 400 to 600 rpm while others rotate at 1 200 rpm. Ingredients such as condensed fish or fermentation solubles, molasses, or fish oils are often premixed in a bowl type variable speed mixer, blending the liquid with dry ingredients.

Parametric Studies of Cement Production Processes

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO<sub>2</sub> emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity. The ...
