Measure your piston's diameter. Be sure to measure the actual piston, sometimes referred to as a bore, rather than the outside of the hydraulic cylinder to obtain the correct diameter (D). Calculate the piston's radius. Radius is calculated by dividing the piston diameter by 2 and squaring the result (r 2). Calculate the piston's area.

You are now ready to test the 12 cc model hydraulic lift, the 35 cc model hydraulic lift, and the 60 cc model hydraulic lift (all with a 12 cc primary syringe, or primary hydraulic cylinder). All three model hydraulic lifts should have a primary and secondary syringe, and hydraulic fluid, or water, in the primary syringe and tubing.

Based on experience, millliner designs have moved toward more openshell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1.

Cleary (2001b) used the discrete element method (DEM) to investigate the effect of lifter pattern on the specific power draw (kW h/t) of a 2D mill, concluding that substantial influences of the lifter pattern only occur for relatively high velocities of the mill (greater than 80% of critical speed).

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.

The easiest and safest way to adjust the instrumentation is to very carefully monitor all bearing temperatures during startup and under normal grinding conditions. Adjust the individual set points for each bearing 10°F (°C) higher than the stabilized temperature for "alarm", and 15°F (8°C) for "shut down".

Use Pascal's Law: To calculate hydraulic pressure, apply Pascal's Law, which states that pressure is equal in all points of a confined fluid. The formula is: Pressure = Force / Area. Convert units if necessary: Ensure that the force and area are measured or expressed in consistent units (, Newtons for force and square metres for area).
