Sep 14, 2012 lead crushers (.325 x .500) typically register the low-pressure loads in rimfire guns and shotguns (though small-diameter copper crushers can be used too). crushers are calibrated in a test press. pounded by high pressures, crushers don’t register peak pressure accurately because the flow of copper is slower than the change of pressure in the.
T eck’s highland valley copper approached crusher vision in 2009 with the hope of finding a way to more accurately predict mantle life and reduce downtime for its gyratory crusher. at the time, the mine was using the bucket test – having someone manually lower a tin can into the crusher to be squished between the mantle and concave, then bringing it back up to measure its width and adjust.
The pressure in the cartridge case expands the case somewhat so that the force is transmitted to the piezoelectric measuring quartz elements arranged in the pressure transducer through the cartridge case and the diaphragm on the pressure transducer. the electrical charge of these quartz elements is led to an electrometer or charge.
