Hi List: We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 4-20mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.

On Mill Installation and Maintenance. Before starting the erection of the mill, adequate handling facilities should be provided or made available, bearing in mind the weights and proportions of the various parts and sub-assemblies. This information can be ascertained from the drawings and shipping papers.
Figure 1 shows a tilt-pad bearing capable of accepting both radial and thrust loads. Figure 2. Layers of Journal Bearing Structure. Journal bearings operate in the boundary regime (metal-to-metal contact) only during the startup and shutdown of the equipment when the rotational speed of the shaft (journal) is insufficient to create an oil film.

With the design criteria established the following repair/reinforcement procedures were performed. Initially the mill was jacked-up to remove the weight of the mill and the charge from the trunnion. The sections in the upper half of the trunnion that either exhibited cracking or were less than 1.905cm (.75″) thick were removed.

A white metal bearing is essentially a composite bearing. Hard crystals are dispersed throughout a softer metal. As the bearing wears, the softer areas erode and create paths and pockets for the lubricant. The softer material also protects the bearing from damage caused by abrasive particles. Since the bearing is relatively soft, abrasive ...
