It's all about the fan. Air swept mills are used primarily when grinding light, relatively non-abrasive materials to a mid range to fine particle size because lighter particles require suction to overcome the rotor airflow. The fan pulls the material from the mill in-feed through the grinding chamber. In
tion for a tandem cold rolling mill based on industrial constraints [4]. Pires et al. utilized a non-linear simplex optimization method to optimize reduction distribution in tandem cold mills [5 ]. Okada et al. investigated the eect of pass schedules in a tandem cold rolling mill. Based on the numerical optimization methods, they improved the
Industrial size reduction generally falls into two basic categories. Particles are either crushed or milled. While crushing breaks down larger chunks, milling reduces the material to a low micron range and, in some cases, can even achieve sub-micron reductions. ...

Acid-free descaling methods such as high-pressure sandblasting and iron particle friction descaling can also be used. (2) Cold rolling: A pickled strip is rolled to the thickness required by the finished products on a cold rolling mill. Metal sheets and strips will produce different levels of work hardening in the rolling process.
Through cold reduction, the thickness of the metal can be reduced by processing steel strip through a sequence of tandem rolling mill stands. The rolls on these stands are stacked vertically and powered by huge motors. ... Can Metals other than Steel Benefit from a Cold Rolling Mill? Though cold rolling is most often used on steel, many alloys ...
