A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Jul 26, 2013· Journal bearings are being removed from a large steel mill gear box prior to doing shaft repair work. Simply put, a journal bearing is a shaft or journal rotating in a bearing. The shaft rotates in the bearing with a layer of lubricant separating the two parts.

The Ball Mill Driving Device Fault and The Main Bearing Lubrication Analysis (Tong Junfeng) 2075 The friction consumption between the ball mill machine body and support bearing is equal to the total mass multiplied by friction coefficient. Since the total mass is quite large, the friction is also large.
A ball mill investigated in this study is used for grinding of limestone in a cement plant. It consists of a large cylindrical shell which ends with inlet- and outlet tubes that are supported in journal bearings. The drive of the ball mill consists of an induction electric motor, two-stage gearbox and the pinion gear.
