Rolling (metalworking) - Wikipedia

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.

Rod mills, how they function - Mine Engineer.Com

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

Copper in the USA: Copper Fabricators

The wire rod mills' share of metal consumed has grown sharply over the last 20 years, to about 49% today, while brass mills have dropped to 40%. Foundries account for about 7% of fabricated products, and powder plants use only about 1% of the US supply of copper. Copper wire mill products are destined for use as electrical conductors.

Modelling the processing of gasifier feed

Performance evaluation of the rod mill The macro parameter to understand the performance of the rod mill is F80 and P80 (particle diameter which is larger than 80% of the inlet/outlet mass). The other parameters are the power input to the rod mill which in turn is closely related to the filling degree (% of rods) in the rod mill.

Bond Ball Mill Index Test | JKTech

A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.
