Consistent Particle Size: Laboratory crushers and pulverizers are designed to produce uniform particle sizes, which is crucial for ensuring the accuracy and consistency of mineral analysis. By reducing the mineral samples to a consistent size, these machines help eliminate discrepancies that may arise from variations in particle size distribution.

A rock crusher production and operation cost is the sum total of direct and indirect costs incurred in producing a rock crusher. Direct costs include materials, labour, and overhead expenses while indirect costs include machine wear, depreciation, and transportation. Rock crushers are used to reduce rocks into smaller pieces.

The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher.

· There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact.
