size reduction

 · SIZE REDUCTION THEORIES The energy requirement for particle size reduction is a function of input and output of particle size, hardness, strength and other properties of solids. Various theories for energy requirement are: Rittinger's theory Kick's theory Bond's theory. 17. 18.

Crushing and Screening | AggNet

They are very effective at fine crushing down to 1/8in size, and providing a cubical product. Hammermills – Hammermills are primarily used in soft and nonabrasive appliions. They are usually installed to make finer graded finished products and require high horsepower per ton per hour produced, typically around two horsepower per ton of material crushed to make a 1in product.

Crushing | McLanahan

Crushing. Crushing is often one of the first steps in the production of rock, coal and other minerals, as mined material can consist of boulders that are too big to fit through the processing plant. The type of crusher required depends on the material being reduced. McLanahan specializes in a variety of crushing solutions for reducing minerals ...

Size Reduction and Energy Requirement

 · In designing a plant for size reduction the two main features of interest are. the power required for size reduction, the choice of crushers and grinders. The power or energy required is the sum of the work required to crush or grind the rock as well as to rotate the mill.
