To this day, most published chamber pressure 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.rimfire firing-pin indent copper crusher 2017. copper-crusher function measuring barrel chamber pressure. In order to ensure consistent and standard design of ammunition, it is necessary to measure the barrel chamber pressure generated by ignition of ammunition cartridge powder in the firing chamber of a barrel.
oct 13, 2014 cup pressure measurement the cup system uses a copper crush cylinder which is compressed by a piston fitted to a piston hole into the chamber of the test barrel. pressure generated by the burning propellant causes the piston to move and compress the copper cylinder. this will give it a specific measurable size that can be compared to a set deformation of the copper crushers used for the estimation of the peak pressure. conversely to the piezoelectric transducer measurements, where the standard deviation on the measured peak pressures increases with increasing peak pressure, the standard deviation of the copper crusher measurements is relatively independent of the

copper crusher for mortar in singapore. 187 scale mortar carrier rnuuy by wachapman on shapeways learn more before you buy or discover other cool products in vehicles We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;ball mill, flotation machine, concentrator and other In normal pressure proof barrels, barrel has one drilled hole for chamber pressure measurement whereas, in this study, a comparison of pressures measured by copper crusher as well as piezo is done at the same location using same barrel keeping all other parameters constant.
military lup abbreviation meaning defined here. what does lup stand for in military? get the top lup abbreviation related to military.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.
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 dtic study of pressures recorded on copper crusher. records of pressures were obtained by using the same copper crusher cylinders for several rounds these were compared with the pressures obtained by the usual method during the firing of pressure rounds in
In the field of interior ballistics, crusher gauges are still widely used for the gas peak pressure measurement within a fired ammunition. under the effect of the gas chamber pressure, a copper copper crusher pressure gauge quarry crusher. copper crusher pressure gauge quarry crusher tph jaw mining crusher from central africa website gyratory crusher at central africa emarg jaw crusher and gyratory crusher is the primary mobile stone crusher capacity tph in south africa it can manufacture from to of coal crusher for sale in germany coal coal crusher for sale in
jan 01, 2020 the crushed copper ore passed through a sieve of mm was evenly mixed and divided into two parts for further crushing by a jaw crusher and a high-pressure grinding rolls respectively. both the width of discharge port of jaw crusher and the distance between the two rollers supply of copper crusher type compressed to 3.2 ton to supply of copper crusher type compressed to 3.2 ton to be used in base pressure system of piston area in document type: tender notice click here for login.

It can be concluded from fig. that more copper is recovered from the high-pressure hpgr products in most of the cases. also, as the particle size decreases copper
jan 01, 2016 length of roll. diameter of roll the maximum pressure on particles is inversely proportional to the interparticle angle of nip and is expressed as max mpa. is a material constant with values between 0.18 and 0.23 and IP is the angle of nip for interparticle comminution, defined in jan 01, 2017 the comparison between copper crusher and piezo sensor for chamber pressure values indicates another fact that copper crusher values for the same ammunition and simultaneous measurement with piezo sensor are not only erratic in nature but also on the lower side which validates our initial assumption of nonsuitability of copper crusher measurements.

the m-11 copper crusher gage is a device which measures peak pressure developed in the chamber of large caliber weapons. this gage is one of two models used by the u.s. army in testing gun systems and is used for high pressure measurements between 150 and 550 mpa. In the third nato crusher gage comparison trials held at meppen,when the gun is fired the copper pellet is crushed by the pressure to some degree. the amount of this deformation is then precisely measured and a very standardized indication of pressure is determined. To this day, most published chamber pressure data for metallic cartridges is taken by the copper crusher method of measurement.
kistler pressure transducer and the copper crushers. all measurements were taken at in a completely enclosed shooting test stand free from weather influences. results of this series have been used in the second part of this paper to study the dynamic behavior of copper crusher gauges. 2.3. results and discussion 2.3.1.peak chamber pressure can be measured mechanically with crusher gages or electrically with electrical pressure transducers. although this paper does not address mechanical measurement, m-ll copper crusher gages were used in conjunction with electrical transducers in many of the dynamic tests.
