Apr 03, 2020· The service life of the bearing is greatly reduced. At the same time, it will be difficult to dismantle it from the grinding roller due to over tightening when the bearing is damaged, which will bring further difficulties to the vertical grinding mill. If it is too loose, the gap between the grinding tracks will increase, and the grinding roller & the bearing cannot be closely connected.

Abstract. Section 17 of Leibniz's Monadology contains a famous argument in which considerations of what it would be like to enter a machine that was as large as a mill are offered as reasons to reject materialism about the mental. In this paper, I provide a critical discussion of Leibniz's mill argument, but, unlike most treatments, my discussion will focus on texts other than the ...
