The work at Polysius and described by Friedrich and Baum, and Otte indicates considerable metallurgical advantage in the extraction of minerals such as gold and copper by the use of high pressure grinding rolls. In this chapter, these two types of roll crushers are described.
Copper crusher method. Through the mid-1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug. It is then removed, measured, and compared to the original dimensions.
Copper crusher cylinders are produced according to strict requirements on precision and material purity.Own machining capability, heat treatment and polishing alow part customisation. In house developed calibration pressing and pre-pressing provides full control of the production process.

CUP - Copper Units of Pressure. In this pressure measuring technique a hole is drilled in the chamber and a piston fitted that presses on a calibrated copper slug (or crusher). (Some set ups also drill the cartridge case which changes the results compared to non-drilled cases.) The whole assembly is held in place with a yoke.

A: Copper Unit of Pressure (CUP) is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load. Originally, a precisely formed copper slug was placed in a fixture over the chamber. When the cartridge was fired, the amount of crushing measured on the slug allowed engineers to determine the pressure.
CRUSHER MEASURING SYSTEMS. For more than 70 years we, the WILHELM HANDKE , produce a lot of various types and standards of crusher gauges and copper-crushers for internal ballistic pressure measurement, by order of a great many military …
A copper crusher gauge holder for testing internal pressures of cartridges during test firing is provided. The copper crusher gauge holder has a circular aluminum upper plate and a circular aluminum lower plate having a layer of urethane rubber approximately 34 inch thick sandwiched between the plates. The gauge holder is bored to hold copper crusher gauges and center-bored to fit over a ...
Copper units of pressure Wikipedia OverviewMethodologyComparing unitsCUP and LUP pressures vs. transducer pressuresExternal links. Estimation of pressure using CUP and LUP units is performed by a special crusher gun, which uses pressure applied to a piston to crush a carefully manufactured and calibrated copper or lead cylinder.
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
A soft copper rod (crusher) sits atop the piston and is restrained by an anvil. When the cartridge fires, pressure pierces the case and drives the piston into the copper crusher. This force shortens the crusher and the length is measured.

Because the indicated pressure from crushers is known to be off, SAAMI many decades ago began referring to the indicated pressure from their tests as "Copper Units of Pressure," a clumsy name commonly shortened to "CUP." For low pressure cartridges such as shotshells, lead is used for the crusher, and SAAMI refers to these numbers as "LUP."

Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.
Gun chamber pressure is an important parameter in proofing of ammunition to ensure safety and reliability. It can be measured using copper crushers or piezoelectric sensor. Pressure calculations in copper crusher method are based on linear plastic deformation of copper after firing. However, crusher pressure deformation at high pressures deviates from the corresponding values measured by ...
