With the increasing speed and milling time, the heat also increases. This might trigger the risk of damage to the nutrient value of the grain. So, look for mills that keep the heat under 155°F to prevent damage. Grinding plates: A mill with superior quality grinding plates is considered an ideal choice. Power: Electric mills require power.
The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.
Typically, the mill throughput will increase between 6 and 9%, if you have a variable speed mill. Liners are often designed with this in mind. The trend in mill liner shapes has changed from olden days when the liner/lifter pitch set = 2 x mill diameter in (ft.). Today, the liner pitch set should be half that ancient value or less.
