Hence, if we were to approach point-counting sensibly, step size is a consequence of determining our sampling strategy, not an input to it. In other words, step size is irrelevant. We have temporarily overlooked the original reasoning behind the adage that step-size should be 1.5 times average grain size; it's time to look at this as well.

1. Introduction. In modern cement manufacturing, the clinker nodules from the rotary kiln are characterized by extremely wide range of size distribution from large grains to fine dusts and their chemical compositions and microscopic textures vary systematically with grain size.

The clinker grain size distribution was analyzed with a Mastersizer 2000 from Malvern Instruments. The most usual way to express results is in graphic form through the grain size distribution curve.

The cement clinker grinding circuit reduces the feed from 80% passing size between 10 and 20 mm to passing 90 μm.The size reduction takes place in a two- compartment tube mill; the first compartment of the mill is shorter than the second compartment.

That is, the clinker grains smaller than a certain grain size are fluidized but other clinker grains larger than such critical grain size are not fluidized. Since the coarse clinker grains are not fluidized, they are left on the high temperature grate 5a and carried in the form of a clinker layer 6 from said grate 5a to the low temperature ...
