Sand plant

This project involved designing a plant to explore the opportunities for manufacturing high quality sand, principally but not exclusively, for use as fine aggregate in ready-mix concrete. Its function is simply to improve particle shape to an acceptable degree, realign the particle size distribution according to whatever specification is required, and to exercise control over the microfines (material passing a 63µm sieve) content.

These are the factors that can be affected by existing mechanical methods. Dry processing was chosen because it opens up possibilities for the creation and sale of subsidiary products, but also on grounds of cost, space requirements, waste handling and disposal and other environmental reasons.
