Rimfire Firing-Pin Indent Copper Crusher

2018-7-27  Swedish chemist Alfred Nobel developed the copper-crusher pressure-measuring system in the mid-1800s simultaneously. Rodman’s invention, the crusher system, is still in use. The crusher system uses a small bar (crusher bar) of copper (Fig. 4) mounted between a stationary anvil and small

Metallic Cartridge Chamber Pressure Measurement

2016-4-21  To this day, most published chamber pressure (MAP) data for metallic cartridges is taken by the copper crusher method of measurement. The proper name for this type of measurement is CUP, or Copper Units of Pressure. Another, similar, method uses lead crusher pellets and the resulting pressure values are called "Lead Units of Pressure," or LUP.

Particle damage and exposure analysis in HPGR crushing

2011-10-1  The average copper recovery from two replicates after 10 days of leaching as a function of particle size and crusher type for the copper oxide ore samples is shown in Fig. 12. It can be concluded from Fig. 12 that more copper is recovered from the high-pressure HPGR products in most of the cases. Also, as the particle size decreases copper ...
