The basic design of these mills is the impact size reduction that is coupled with an internal dynamic classifier which controls the outlet (product) particle size via recirculating the coarse particles back into the grinding zone. There are seven main factors which determine particle size distribution for the Mikro ACM® Air Classifying Mill.
Spex a mill resulted in an average 8% increase in total C compared to the roller mill, which is attributed to abrasion of the steel grinding vessel and ball bearings (Table 2). This hypothesis was verified by reprocessing a series of soil samples through the Spex a mill which resulted in an average

Properly designing a heavily loaded journal bearing requires knowledge of the contact pressure to ensure it is within the materials' operating limits. It is common to use the average contact pressure, the applied load over the projected area (P=L/(D*W). However this severely underestimates the actual maximum pressure on the system.
hydrodynamic journal bearing, wheel spindle used for submicron precision cylindrical grinding. In particular, the spindle of interest is a wheel spindle for a large cylindrical grinder, operated in the horizontal mode. The weight of the spindle shaft/ wheel assembly functions as the primary load. The effects of lubricant, speed, and temperature on
