Mobile Sand Washing Plant to Make Manufactured Sand
Urban development is the key indicator of the growth of the Indian economy, and construction – both infrastructure and real estate – play a key role as a gauge and measure of growth. Sand, the backbone of the construction industry, has become a problematic resource to procure in India. Availability and inferior quality have both contributed to the price volatility in this resource – classified as a minor mineral under the National Mineral Policy instituted in 1993. With the problems associated with sand, namely illegal mining by sand mafia, heavy price volatility, inferior quality and non-grade material, high demand to spurt growth, sand is nothing less than a critical mineral of very high value. Whether a river sand mining ban by NGT, or a state government regulation to optimally dredge the rivers, the problem with sand supply cannot be resolved by only institutional regulation. The industry needs an answer to the underlying supply side problems.
The most trusted alternative to sand is Manufactured sand (also known as M-sand). This technology helps alleviate the risks associated with natural sand procurement. By de-risking the construction sector from heavy price volatility, dependence on illegal sand supply – manufactured sand provides uninterrupted supply and consistent quality, which no institution related to the natural and river sand regulations has been able to deliver.
Manufactured sand as a concept, has many manifestations in the current Indian market. Unwashed quarry dust, crusher dust (both 2&3 stage) is being passed by that name. To take care of the excessive ultrafines/silt in the so-called Sand, cleaning system has been introduced. Many such introductions like bucket classifiers and screw classifiers have, however, failed to deliver on the promise. These old age technologies can neither produce correct sized product nor are the products free from deleterious slimes & silt to the required extent. Another major drawback of these plants is their inability to handle varying feed types. The only reliable technology to produce manufactured sand is a highly
Combo 7-in-1 Mobile Solution for washed manufactured sand
CDE is the world leader in material washing equipment, providing novel means to save our planet by preserving its resources. The company has extensive experience in producing high quality manufactured sand in number of countries around the world and have successfully installed more than 200 washing plants in India making manufactured sand a preferred option in 30 cities across India.
CDE’s flagship Combo sand washing system delivers washed, dewatered, and well-graded Zone II concrete sand. This is RMCready, impurity-free, vastu-friendly sand that is being readily used for manufacturing low-cost higher durability concrete.
Combo denotes the word ‘combination’ of 7 functions of green wet processing technology that will save water, land, and energy and not create pollution hazards at project site.
The compact plant incorporates all the actions involved in washing process e.g. screening, classification, dewatering, water management etc. in a single chassis. This enables the plant to be installed in a small area with attendant advantages of lower power & water consumption and thus, low operating cost.
challenging technical process involving washing and grading of sand. CDE is the pioneer of this concept and a global leader with its cutting-edge sand technology operating across the planet. This technology uses quarry dust, crusher dust or river-bed material as the raw/feed material to produce the highest quality ready-to-use graded sand, meeting Zone II quality specification under IS 383 for the construction industry. In CDE technology along with Zone II grade concrete sand, some amount of Zone IV sand for plaster can also be produced. The production levels would depend upon feed material characteristics. Recently, CDE has also developed a technology for using the rejected sludge of sand plant for making bricks.
