HOW CIRCULATION GRINDING WORKS The circulation grinding method involves a grinding mill (in this case, the DMQX™ Bead Mill) and a large process/ holding tank that is typically about 10-20 times the size of the mill's grinding chamber. This proportionally-sized tank allows the turnover in the holding tank to happen about every 5-10 minutes.
Large vertical mills integrate the functions of drying, crushing, grinding powder selection, and transportation. The technological process is a typical coupling process integrating fluid, particles, temperature, and other multi-physical fields [1], [2]. When the vertical mill is running, a large-scale particle–fluid coupling system is formed ...

A smaller diameter has been shown to restrict circulation. Circulation ratio is one of the important criteria for estimating the downtake diameter. Ideally this should be less than 2.5 to obtain a pan with good circulation, although a number of pans that have circulation ratio values up to 2.8 have given reasonable results. Tubes

The dryer steam dries the cleaned blanks before they move to the upsetting mill. Step Four: Upsetting. Upsetting means to "upset" the edge of a coin to create a raised rim. The upsetting mill feeds the blanks into a groove slightly narrower than its diameter. This pushes the metal up around the edge to form a rim.
