  • CFD simulation of a centrifugal air classifier used in the

    A centrifugal air classifier used in the aggregate industry was investigated using computational fluid dynamics (CFD) to improve the understanding of the influence of the geometric design of the classifier on the cut size and the resulting particle size distribution. Simulations were performed with a CFD model using an Euler–Lagrange approach.

  • Classification of Aggregates Based on Size and Shape

    Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 % of total volume of concrete.
