Steel - Steel - Billets, bars, androds: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billetmills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-highmillwith box passes, as shown in A in the figure. After a rectangular ...

In rollermills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. In ballmill, size reduction is done by both impact and attrition of particles.Rodmillis similar to ballmillsbut it uses longrodsfor grinding media.

Size Reduction - Visual Encyclopedia of Chemical Engineering

Size reduction in attritionmillsoccurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer level.

Crushing in Mineral Processing
Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones ...
