Ball Mill TRUNNION BEARINGS. Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion.Ball mill accessories include big gear, pinion, hollow shaft, ring gear, big ring gear, steel ball, compartment board, transmission, bearing, end lining, and so on.

MONSAG: A new monitoring system for measuring the load filling of a SAG

Evans (2001) described a method for determining charge mass in SAG mills by using hydrostatic lift pressure, bearing loads, mill power and speed. An interesting approach for modeling and inferential measurement of SAG mill parameters has been given by Apelt et al. (2001),comprising a formulation for soft sensor development The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’sWhat’s the Difference Between SAG Mill and Ball Mill

Grinding Mill Design & Ball Mill Manufacturer 911 Metallurgist

Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing. Small and batch grinding mills, with a diameter of 700 mm and more, are available. These mills are of a special design and described on special request by all Ball Mill Manufacturers.The Sydvaranger SAG mill. Originally, the mill was supported by five shoes on each side: one at the bottom 6 o’clock position and two on either sides of it. The stability of the bearing was questionable and as in the case of Chuquicamata, the mill was escaping sideways from its bearings.
