Top 6 Things You May Not Know About Mills & Grinders

1. The process of grinding and milling has its origins in prehistoric times, when early humans pounded grains and nuts with stones to free the kernel from the hard protective shell. The earliest dedicated tools for this task are the mortar and pestle, which were developed during the Stone Age and have remained essentially unchanged throughout history.

2. Millstones, including the saddlestone—developed in 2000 BC—were the predominant grinding tools used until about 2500 BC, when the rotary quern was invented. The quern required a circular motion, which was much easier to maintain than the back-and-forth motion of the saddlestone. Although the particles produced from the quern were not as fine as could be achieved with the saddlestone, the quern became very popular because of its increased ease of use.

3. Around 1500 AD, the grinding of minerals was revolutionized when high demand for metals led to the development of water-driven stamp mills for grinding large volumes of pebbles into small particles. At this time, stamp mills were developed in which the pebbles were shattered by impact from a pounding hammer.

4. It was during the second half of the nineteenth century that jaw crushers, ball mills and air classifiers were developed. At the same time, high-capacity machines for ores and cement were introduced, with Schranz inventing the roller mill for grains in Germany in 1870. A patent for a beater cross mill with hinged hammers was granted to H. Currier in Great Britain in 1875.

5. The first two decades of the twentieth century saw the invention of vertical roller mills, as well as autogenous pebble mills in which rocks are thrown into a rotating drum, causing impact breakage of larger rocks and compressive grinding of finer particles. Rake classifiers were also introduced during this time to separate the fine particles from the coarse.

6. In 1909, the first patent for cryogenic breakage was granted to Gaston Galy. Cryogenic breakage employed liquid air to cool the sample before crushing to make it more brittle and increase the crushing efficiency.
