Study on the particle morphology, powder

2021-2-8  Reasons for this effect are as follows: (1) The ball-milled slag has a wide PSD and a better stack performance. The powder also contains an abundance of fine powder at the micropowder grade, which increases the initial hydration speed. (2) The ball-milled slag has a higher degree of sphericity.

2018-11-30  which most powders belong, the fracture energy is 1 to 10 J/m2 (103 to 104 ergs/cm2). In na ideal size reduction process, the particles from a homogeneous material would be of the same strength, regardless of size. Therefore, a plot of fineness atained versus work required to obtain that fineness would be a straight line.

Process optimization of jet mills for metallurgical

It is concluded that density and hardness seem to have a significant effect on the product fineness. Hard materials such as TaC, WC, and WTiTaC resulted in a finer product size than soft materials like TiC.

Size reduction - Solids and powder milling -

2021-2-20  1. Principles of milling bulk solids. Milling is the action of reducing the size of particles thanks to a mechanical action. The mechanical action is submitting the particles to a stress, under the stress, some cracks will appear and subsequently the particle will be broken in different parts.

2020-3-19  Air classifiers can separate powders as coarse as 80 mesh (180 microns [μm]) and as fine as 2—3μm. The fineness of air- classified products is controlled by a precise balance between the quantity of rejector blades, the speed at which rejector blades operate, the velocity of the airflow and the rate at which the material is fed.

The material is therefore milled against itself. The process can mill tougher and more abrasive materials, which would otherwise be a problem in mechanical impact mills. The internal air classifier holds material inside the mill chamber until it achieves the right fineness. Air jet mills use high levels of compressed air, thus are expensive to run.
