Ever since they were invented back in the mid-19th century, roller mills were a game changer for the milling industry. This is because they come with a lot more advantages that other types of mills cannot provide. Here are the main advantages of roller milling that have made this type of milling survive these many years.
First is that roller milling preserves the moisture content of the grains so that further processing and other requirements are not affected. Also, it becomes easy to optimize large scale operations and practices such as wetting the grains before grinding them using roller mills will not be required.
The other advantage of roller mills is high effectiveness. One mill can have different rollers arranged one after the other so that the grains fall from one to the other to achieve the required consistency quickly unlike in the hammer mills. This high efficiency in operation also makes the roller mills more energy efficient.
During operation, the roller mills are usually quiet and do not produce a lot of heat. The silence makes for a good work environment reducing fatigue and noise pollution. Increase in temperature of any machine during operation means there is loss of heat during operation. This is not the case with roller mills which further causes more power savings.
Also, a roller mill is able to achieve high levels of uniformity in the end product making it suitable for use commercially because customers demand consistency in the products they purchase.
