hardness on fragmentation of rocks by means of hydraulic hammer and during crushing in jaw crusher. The testing was carried out on the rock samples from five quarries. According to the obtained results the hardness has a considerably larger impact on the fragmentation energy by hydraulic hammer than on the crushing energy in jaw crusher.

No method of measuring chamber pressure is 100% accurate. If you measure 100 rounds of exactly the same load, in exactly the same gun, with exactly the same test equipment using the crusher method the measurements will typically vary plus or minus 5% from round to round. Some rounds may be off from the average for that group by 10% or more.

The classic method of measuring pressures goes back to the 1800s and early 1900s. It was the method most in use until about the 1960s. It uses crusher gauges to determine pressures. It consists of a device that allows mounting of a gun barrel. The gun barrel is drilled at various points where pressure measurements are desired.

Use the following procedure for the perimeter measurement method: 1. Place the rock in its most probable “at rest” laying position. 2. Imagine two vertical cutting planes passing through the rock at nearly right angles to each other. Measure the two resulting perimeters in feet and add them together. 3.

2. Indirect Measurement Method This kind of measurement method is to measure the stress of some certain components and parts, and figure out the magnitude of the crushing force as well as the places of points of action. Its largest merit is that it doesn’t need to process specialized teat master copy, nor to repair or transform the jaw crusher.

The manual soil compaction hammers are lifted to their maximum height and allowed to fall freely onto the soil specimen for the required number of blows. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). The modified Proctor method uses a 10lb hammer with 18in (457mm) drop height for compaction.

Crushers are also classified by their method of mechanically transmitted fracturing energy to the material. Jaw, gyratory and roll crushers work by applying compressive forces while impact crushers such as hammer crusher apply high speed impact force to accomplish fracturing. There are several types of crushers which are used in various industries.
