Structural features of sand making machine: 1. The main shaft assembly of the sand making machine is installed in the middle of the square prism. It transmits power from the motor through the V-belt and keeps the impeller rotating. 2. The impeller is installed on the shaft head at the upper end of the main shaft assembly.
Artificial Sand vs. Natural Sand. Manufactured in factory. Naturally available on river banks. The shape of crushed sand is cubical and angular and has a rough texture and hence better for concrete. Smoother texture with better shape. Demands less water. Higher concrete strength compared to river sand used for concreting.
