20/09/2020 Three distinct filler particle fractions were produced by a planetary high-energy ball mill from limestone aggregates (2.36–4.75 mm). Their particle sizes and shapes were studied by binary image processing and related to milling time and aperture size. The relaxation properties of asphalt mastics prepared with fillers of various sizes and shapes were investigated at a constant strain. Insights into the effects of particle size

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...

To heat the limestone evenly in the kiln, the particle size of feed must be relatively uniform. To avoid long residence time in the kiln, the particle size of limestone must be small, typically about 1 ½”. However, due to the nature of the crushing operation in reality, there is a range in size from ½” to 2”. Since the residence time and
