The gypsum sand that makes up the dunes is unique in several ways. Unlike typical sand composed of quartz, gypsum sand is softer and cooler to the touch. Gypsum has a high evaporation rate, which prevents the sand from absorbing heat, making it comfortable to walk on even in the hottest weather. The sand's bright white …

obtaining different sand grades. Sieving of grains is done manually and consumes lot of time. Our research work proposes an idea of motorized sieving machine that uses a 12-volt DC motor to vibrate the mesh. The machine shall have changeable mesh based on the sand grading requirement/grains to be sieved. Keywords:- Sieving, Sand, Grains.

The kind of sand sifted was 87.30% passing by volume through the sifter. The fine aggregates comprise 87.30% of the total mixture while the bigger sizes comprise 12.70% of the total mixture. The bigger sizes of sand that remained in the sifter are removed automatically passing through the sifter opening. It was concluded that motor- operated ...

Gypsum is a soft mineral with a hardness of 2 on the Mohs scale, which means that it can be easily crushed and broken down into small particles. This softness is what allows the sand to be easily blown and shaped by the wind. Additionally, gypsum has a unique ability to absorb and release water. This means that the gypsum sand at …
