M-Sand is manufactured sand, obtained from specific hard rock (granite) using the state-of-the-art International technology. Its numerous advantages over river sand have made it a favorite and a “Must-to-Use” with quality conscious builders.
For Crushing Process, we using Vertical Shaft Impactor (VSI) is an improved version of ‘Rock on Rock configuration,’ way ahead of all conventional types available in the market. The VSI is developed at R&D department with various inputs available from aggregate produce.
It could be easily converted to handle anvil rings and rocks. This simplified Retro fit could be easily and swiftly installed on existing conventional model without major modification in the setup.
The high velocity impact crusher in VSI enhances the shape of the Aggregate/Stone, reduces the product moisture, resulting in perfect shaped products at considerably less operating cost. Propel VSI is suitable for all type of materials, waste and recycling applications. This is achieved through unique combination of speed and crushing action.
In Screening Process, we are using Vibrating Screens offer versatility as well as high-performance screening in a compact, value engineered package. Vibrating Screens are effective for highly demanding applications in multi-stage crushing plants and mobile installations.
MVS screens are versatile and can be used for secondary and tertiary screening as well as primary screening. MVS screen of standard slope angle is 18; however this can be modified for special applications.
MVS screens consists of modular components with huck bolts, high tensile special alloy side plates, well designed deck frames cartridge type modular vibrating mechanism and cardon shaft system. The high engineered huck bolt fastening system has proven to be a very safe and reliable method.
MVS screens can be used for wet screening fitted with spray pipes. MVS screens feature a unique combination of characteristics that result in high capacity and high efficiency screening as well as long service life.
For water wash, we are using Pro Wash are designed to ensure maximum efficiency in our washing plant. Our Pro Wash is developed to deliver high quality washed sand to the international construction market. The Pro Wash modular design facilitates extremely accurate separation of silts and clays from final washed sand products.
Pro Wash systems are employed in the production of specialist sands for diverse usages. The innovative design features makes our Pro Wash an ideal choice for our customers.
The particle shape of the aggregates is very important for making concretes. It is a well known fact that the sand having cubical particles with grounded edges gives higher tensile strength and compression strength to the concrete. The grains should be of durable material and the size of the grains must be such that it should give minimum voids. The presence of clay and slit is avoided since it retards the setting of the cement and making mortar. Experiments shown that considerable variations in strength of гидра mortar may occur owing to form and variety of the sand particle. The strength of mortar may differ by about 50% of average. It is not possible in river sand that all particles should be of higher strength. This can be achieved only by making sand with the help of machines. In machine-made sand, we can use the raw material of higher strength.
The manufactured sand produced by proper machines can be better substitute to river sand.
There is discrepancy in the river sand for two loads lifted from same source. Hence to achieve consistent quality, each truck of sand should be tested. Moreover the sand has to be sieved to remove stones, slit and clay. In routine average wastage of sieving are about 35% and extra labour cost involved. Whereas VR M-Sand is ready-to-use-sand with no wastage since it do not have organic impurities. The superior shape and gradation of VR M-Sand ensures high strength concrete with significant savings in cement.
