From a maintenance perspective, slipper pad / slide shoe bearings are maintenance free. It is the oil supply to them that requires the maintenance in terms of cooling and filtration. The traditional trunnion mounted mill is a wellknown and widely used machine. Whereas the slide shoe supported or shell supported mill is relatively young.

Traditionally trunnion bearings have a much higher specific load, as the available surface area is restricted by the trunnion diameter. Slide shoe or slipper pad bearings (as fitted to shell supported mills rather than trunnion mounted mills) are fully selfaligning, subjected only to compressive loads, and as long as the oil supplied to them is maintained, they will outlast traditional ...

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill ...

Floating ball valves are the most used of the two. Trunnionmounted valves are specified when larger pipeline sizes and highpressure conditions are involved (class 600 and above). Knowing the key differences between the floating and trunnionmounted designs is essential to meet process, budget, performance, and maintenance targets.

The trunnion ball valve is an essential device for regulating the flow of fluids steam, gas, or oil in pipeline. It is quarterturn designs with a ball capable of rotating 90 degrees on its axis to either block or allow the flow of fluid. These valves have a spherical disk design at the center, which rotates to regulate the startstop flow cycle.
