Herein, the chemistries of the binary Li 3 N·P 2 S 5 solid electrolytes, produced by ball milling, are studied in detail and reaction mechanisms are proposed. We show that less nitrogen is present in Li 3 N·P 2 S 5 solid electrolytes after ball milling than is expected due to the evolution of N 2 during the early stages of milling.

Ball Milling - an overview | ScienceDirect Topics
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

Ball milling is another technique which was reported very recently for the production of NFC. In this method, a cellulose suspension is placed in a hollow cylindrical container, partially filled with balls (e.g., ceramic, zirconia, or metal). While the container rotates, cellulose is disintegrated by the high energy collision between the balls.

Ball-milling of graphite to obtain graphene materials is one of the many versatile methods to easily obtain bulk quantities. In this work, we show that the graphene materials produced by ball-milling are spontaneously contaminated with metallic impurities originating from the grinding bowls and balls.

Chocolate mass processing technologies - an overview
Ball milling. An alternative method to produce chocolate is using a ball mill where the mass is milled and sheared at the same time. Although cocoa liquor is usually ground by ball mills, those are not popular for chocolate mass in the European industry. Nevertheless those systems are commonly used worldwide.

Ball mill - Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

How Ball Bearings are Made - Sheldon Brown
In his workshop for velocipedes, bicycles and tricycles he therefore worked intensively on the production of high-quality balls. The marble ball mills described above were probably not the model for Friedrich Fischer's ball milling machines. He developed, however, a similar production method (Figure 35, below).

Ball Milling. Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.
