Metallic Cartridge Chamber Pressure Measurement

Another, similar, method uses lead crusher pellets and the resulting pressure values are called "Lead Units of Pressure," or LUP. Lead is more easily deformed than copper, and the LUP method is normally used for measuring relatively low chamber pressures, such as those generated by shotgun shells, while copper crushers (CUP) are used for measuring the pressure of handgun and rifle cartridges.

Choosing the right crusher

Choosing the right crusher. A crusher is a machine that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size. They are particularly used in the mining industry to reduce the size of ore blocks and facilitate their processing. Crushers are designed to receive blocks ...

Rock Crushing Theory and Formula using Kick & Rittinger''s Law

 · Appendix: Rittinger''s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: "The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given ...

Aggregates for Concrete
