High Pressure Grinding KHD Humboldt Wedag Roller Presses. With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oil-lubricated cylindrical roller bearings.

The IGF is supplied with a standard pressure roll assembly that is adjustable by means of a spring to hold the part firmly against the blade and regulating roll during grinding. The pressure roll is adjustable so the part can feed axially along the regulating roll in either direction up to the location of an end stop.

High Pressure Grinding Rolls have been used for the grinding of diamond and iron ores since about 1988. There are now about 40 machines operating world-wide in these industries. This number is still small in comparison to the > 450 machines employed in …

high pressure system for cement mill . · Cement grinding Vertical roller mills versus ball mills. The consumption of grinding aid when grinding OPC in a vertical roller mill is typically in the range from 100 g to 300 g per ton of cement With respect to the use of grinding aid for grinding of OPC the ball mill system thus has an advantage compared to the vertical roller mill.

Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.

Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
