01031985· Increasing the rotational speed of the mill decreases the residence time, as was observed in the present work as well as in other models of the Szego mill used for coalslurry grinding [4] Increasing the groove angle 0 and R/H also decreases the traveling time through the grinding zone At low feed rates the holdup in the mill is low, the bed thickness in the grinding zone is small, and aDavid Szego: What we have is an industrial grinding mill Anybody can buy a mill, and it’s an intrinsic part of the recovery process, but The Szego Mill has a few specific characteristics that no other kind of milling or grinding technology can offer These will come into play when you are processing the ore to make the final product, which is quite aways down the line from the earlyA Better Way to Grind Ore? A Conversation with DavidA Szego Mill was used to wet grind Minto (New Brunswick) coal which was then subjected to laboratory agglomeration by the NRC procedure A comparison with coal ground in a ball mill indicated superior ash rejection The improved performance is attributed to better mineral liberation which is enhanced by the more flaky particles produced in the Szego Mill Abstract fr La technique de lModified oil agglomeration process for coal beneficiation
