Steel Glossary | Glossary of Terms | Platts

When steel is rolled back-and-forth through the same mill, this is a reversing mill. When it moves directly in a continuous process to other mill stands, this is a tandem or continuous mill. These can achieve far higher throughputs than a reversing mill. Tandem mills are associated with flat products and typically have 4 or 6 stands.

Agitation is the process of keeping a mixture that has been mixed in the proper mixed state required for the 'end' product. Mixing refers to the actual stirring of different liquids and/or materials to blend them together into an end product or mixture. Once this mixture is 'mixed' it may require agitation to keep the mixture in the proper 'mixed' state.

Influence of jet milling and particle size on the ...

Jet milling is classified as a fluid energy impact-milling technique generally used for producing ultrafine powders. The final particle size produced by this method is very much dependent on the material being processed (Protonotariou, Drakos, Evageliou, Ritzoulis, & Mandala, 2014). The jet mill is a static machine with no grinding media.
