The ball mill's high pressure oil system is designed to lift the trunnions during start-up by supplying high pressure oil. The high pressure pump is programmed to shut-down after the mill has been running for a predetermined amount of time. The high pressure pump pumps oil through the high pressure supply lines to the trunnion bearings.

circuit P80 target size) material in the ball mill. It can be measured and then increased through pump and cyclone adjustments. By so transferring the application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is decreased. The other factor that determines overall
The Mega Slurry is a high-performance, low maintenance slurry pump recommended for coarse or fine particles from solids-laden waste water to aggressive slurries of an abrasive and/or corrosive nature. Capacity of pump is up to160 GPM @ 100 Ft. TDH. Impeller, chamber made from chromium wear steel alloy, to give good abrasion resistance.
Mills Grinding. Generally ball mills are more common than Rod mills or Sag Mills, there are other types of mills available such as Vertical mills but the last three mentioned are by far the most common. Ball and mills use steel balls or ceramic balls as their grinding media. Rods mills as the name suggest use rods as their grinding media.

The mill, with its heavy weight, rests statically on the slide shoe surfaces. To lift the mill a high-pressure pump pumps lubricating oil into the space between the mill shell and the bearing. This process is referred to as hydrostatic lubrication. When the mill rotates the movement of the mill running surface creates hydrodynamic lubrication.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

When the high lift pump is used for low lift pumping, the motor is easily overloaded and heated, and in severe cases, the motor can be burnt. If it is used in an emergency, a gate valve (or a small outlet with wood or the like) for adjusting the amount of water must be installed on the outlet pipe to reduce the flow to prevent motor overload.
It is similar to a pump lift because it stacks balls on top of each other in a chute. But, there is a wheel at the bottom that lifts balls one by one, so it's much more simple. There is also a rod that keeps the balls from falling back down. Here is a video. Also, he built a ball machine using this lift, called Gravity.

The incoming process fluid is conveyed by the rotating power rotor by means of the cavity ...
involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
