Understanding influence of crushers on shape

Sep 30, 2021The aggregates obtained from VSI crusher had maximum low angularity particles. Therefore, HSI produced aggregates had higher form 2D as compare to CC and VSI. Mean value of form 2D for different aggregate sizes is shown in Table 3. For all aggregate sizes, the HSI produced aggregates had highest form 2D and followed by CC and VSI.

Crushed Stone Aggregates

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing
