Define crushing laws and name different types of crushers
Crushing laws are empirical relationships that describe the size reduction of materials in the crushing process. They help in understanding how energy is consumed during the crushing operation and how the size of the particles changes. The most commonly used crushing laws are the Rittinger's law, Kick's law, and Bond's law.
Grinding And Crushing Laws
Bond's Law emphasizes that the energy input is inversely proportional to the square root of the size reduction ratio. 2. Crushing Laws: Unlike grinding, crushing involves the application of compressive forces to break down materials into smaller pieces. Crushing finds applications in primary crushing operations in mines and quarries.

broken up larger lumps, and is best suited for low-capacity applications in smaller sized units. Both types of crushers, if fed at a high feed rate, will fill the crusher volume and produce a secondary crushing action between chunks of rock bearing on one another, which is known as choke crushing. This type of crushing will produce a
