A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Apr 26, 2019· Transversal rolling of balls from the round billet is economical. It differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 10-15% to reduce the consumption of metal. The process involves the following stages:

One of the keys in the production process is the roll machining. If faulty rolls are in operation, they cause deviations from the profile and surface flaws on the hot strip, which directly impair the quality of the end product. Herkules has delivered customized solutions to hot rolling mills for many decades.

This rolling mill is designed for the production of steel balls that will be used into the ball mills for mines and cement factories. The plant is composed by a stand that transforms the round section bars into balls at the requested size.

Dynamic forces include ring gear teeth forces and grinding process forces. When the mill is in operation, the material to be ground and the grinding elements are lifted by lifters on the mill lining and by frictional forces until they fall back, of their own weight. The centre of gravity of the material in the mill is thus displaced laterally.

greater impact, as the balls tend to reach their break point higher in the mill rather than experiencing just a rolling action. Larger mills are often run at slightly lower % of critical speed because of the more severe grinding action inherent with the larger diameter.
