Granite Rock Property. Granite is a high-quality building stone with a uniform structure, a hard texture and a beautiful color. The density is 2790 ~ 3070kg / m³, the compressive strength is 1000 ~ 3000kg / cm², the elastic modulus is 1.3 ~ 1.5x106kg / cm³, and the water absorption is 0.13 %, Shore hardness> HS70, specific gravity 2.6 ~ …

Firstly, you need to make a wooden frame which will be used as a crushing tray. After making the wooden outline, attach a tarp on top of it. Then place the tray on a bucket. Now put the large lava rock chunks on the tray. Finally, smash them with the hammer. This was just an outline of the whole thing.

This provides a theoretical basis for improving the rock-crushing performance of acoustic drilling machines. ... It helps to further expand and connect oil channels, and at the same time, cemented asphaltene molecular bonds break to reduce the viscosity of crude oil and increase the fluidity of crude oil. After the ultrasonic treatment, …

This involves lifting the breaker after each impact, which helps to fracture the rock more effectively and prevents the tool from getting stuck. Vary the impact points. Avoid hitting the same spot repeatedly. Moving the point of impact around creates cracks and weaknesses in the rock, making it easier to break apart.

A crushing pit beneath the cutter with a broken depth of 1.82 mm is formed, and the total volume of the rock crushing zone reaches 5.06 mm (Saksala et al., 2018). It is worth noting that the propagation cracks in the rock lead to a decrease in the stiffness of the cohesive elements near the crack propagation zone.
