Secondary Crushing: The crushed rock is then further reduced in size using a secondary crusher. This process helps to produce a more uniform size of crushed stone. Screening: After the crushing process is complete, the crushed stone is screened to separate the different sizes of stone. This is typically done using a vibrating screen.
Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.

what is the rock mass strength. Knowledge of roc k mass strength is also important in the design of support systems as discussed in the next set of notes with regard to the concept of rock-support interaction. In general, rock mass strength depends on the strength of intact rock and the strength of rock discontinuities.
