BUCYRUS 49HR PDF

Bucyrus International, Inc. Air compressors de-rate in high elevation and high temperature environments, causing bailing velocity to decrease. As bailing velocity deteriorates, so too will drill productivity. The use of a CFM CMM air compressor utilizing an operating pressure of 65 psi kPa , like the option available for Bucyrus Drills, allows drill operators to maintain target bailing velocity — between 8, and 12, feet per minute 2, and 3, meters per minute — and optimum radial clearance — 1 to 2 inches 2. Bucyrus Drills equipped with CFM CMM air compressors are also beneficial in mines with fractured rock strata, as air released from the compressor can escape into ground cracks, causing loss of air volume.

Bucyrus Drills equipped with CFM CMM air compressors are also beneficial in mines with fractured rock strata, as air released from the compressor can escape into ground cracks, causing loss of air volume. The added power offered by the CFM CMM air compressor will reduce the net loss of air volume in porous ground, ensuring target bailing velocity and optimum radial clearance.

In fact, when compared to a drill equipped with a CFM CMM compressor utilizing an operating pressure of psi Thus, operating at a lower horsepower will lower associated energy consumption and cost while maintaining an equivalent rate of productivity.
