Edge mill Wikipedia

An edge mill is a mill used for crushing or grinding in which stones roll around on their edges on a level circular bed. They were developed in China in the third century and are still used today in remote villages around the world. When the millstones were replaced with iron or steel disks in the 19th century, they were known as a Chilean mill.. It is used for milling ore and as an oil mill.

Practical 1 : Ball Milling TF Lab 1

23/12/2013 In hammer mill, size reduction occurs by impact, by four hammers attaching on a central shaft. In end-runner and edge-runner mills, compression is carried out on a small scale in a mortar-and-pestle form. In roller mills, 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

Roller Mill: Components, Designs, Uses, Advantages and

Roller mill is a form of compression mill that uses a single, double, or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials. One of the rollers is run by a motor and the others are rotated by friction as the material is drawn through the gap between the rollers.

17/3/2017 The Chilian mill closely resembles the edge-runner mill of the present day, which is used for grinding and mixing mortar. The Peruvian trapiche had a similar circular bed of hard stone, but only one stone runner, which was driven by mules. The Chilian mill is still used to prepare ores for treatment in the arrastra, which was not mentioned by Barba, and may perhaps be regarded as an outcome of
