Mintap. The CGap system is supplied with a selection of measurement bulbs ranging from 7mm to 220mm, with an accuracy of 1mm. The colourcoded bulbs are made from tough rubber for high wearresistance. Cable lengths are available in up to 30m, so the system can be used for even large, gyratory crusher units.

Many appliions require accurate measurement of low pressure such as drafts and very low differentials. To better handle these appliions the manometer is arranged with the indiing tube inclined, as in Fig­ ure 6, providing for better resolution. This arrange­ ment can allow 12" of scale length to represent 1" of vertical liquid height. With scale subdivisions, a pressure of ...

The Crusher measuring system is a proved method for the determination of innerballistic maximum pressure in combustion chambers. With the help of a device resp. the Crusher measuring apparatus, a copper body is loaded. The plastic deformation which results from the load is the measure for the pressure. Old price: EUR.

 · Measuring the crusher OSS CSS closed side setting. A certain amount of slippage occurs in all pressure type crushers, regardless of how small the crushing angle may be (that is, within practicable design limits), especially in the lower part of the crushing chamber where the nieces are smaller and lighter. Under normal operating conditions this ...

Until the mid 1960's the only method commonly used for measuring chamber pressures was the copper crusher. Basically, a hole is drilled in the chamber of a firearm and a crusher chamber is attached to that hole. In this crusher chamber is placed a very precisely manufactured piece of copper. When the gun is fired the copper pellet is crushed (deformed) by the pressure to some degree. The ...

Gun pressures can be measured by socalled crusher pressure gauges, which are based on the plastic deformation of cylindrical copper elements. Especially at .

Copper crusher method. Through the mid1960s, 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. Using the known properties of .

Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in terms were adopted by convention to indie that the pressure values were measured by copper crusher and lead crusher gauges respectively.

 · We measure the crusher and consult a table of pressure values provided with each crusher lot. Starting at inch, the table lists decreasing lengths in thouhs of an inch and, beside each length, the pressure in copper units of pressure (CUP) that it takes to shorten that much. The system must be reset after each shot, requiring that you remove the .

Do not fill crusher right up to top of the jaws, this puts too much pressure on jaws and can damage bearings. Speed and Particle size are a factor of how the lower jaw width is set. Read how to adjust dispensary particle size in order to make changes. Smaller Particle size the longer it will take the Jaw Crusher to work through rock, the Larger the particle size setting, the faster the jaw ...
