Hailstone for Transformational growth in Sand Industry

Hailstone as a company exists for a reason – its goal and vision. Hailstone’s solutions to global requirements are driven by our mission to drive transformational growth and our vision to be one of the best mineral processing solutions providers in the world. We are always involved in the continuous development of our products and services to create value for our customers and to support sustainable societies and the well-being and safety of people.

Our products and services contribute to much of what we all expect of a well-functioning society. Hailstone equipment and projects are involved in many of the functions that most of us rely on every day. Hailstone in majority serves the construction and infrastructure industries. The reliability, productivity, efficiency and safety of the products are important and in most cases crucial to our customers’ success and profitability.

Infrastructure growth has seen its peak in the on-going decade and expected to be the biggest player in the global economy. Constructions of all kinds are booming even though some temporary setbacks had occurred in recent times but expected to be the biggest employment provider next to agriculture. Sand accounts for 35 per cent of the volume of concrete used in the building construction industry and as the country ride a growth trajectory. Apart from cement and steel, the other most important component in construction is sand, especially river sand. These three are basic needs for the construction industry. In addition to civil construction, sand is extensively used in different projects, including land reclamations, artificial islands and others.

The industry is witnessing one of the most intractable environmental problems of the building and infrastructure sector in India — the rapacious mining and use of river sand in construction. While the demand for quality river sand keeps escalating every year, the supply is dwindling. Also, concerns are expressed regularly on the overuse of river sand impacting the environment and resulting in ecological and social consequences. Mushrooming of river sand mining activities has given rise to various problems like river bank erosion, river bed degradation, river buffer zone encroachment and deterioration of river water quality. Very often, over-mining occurs which jeopardises the health of the river and the environment in general.

The best Alternative for river sand is manufactured sand (M-Sand) which is a substitute of river sand for concrete construction. Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.M-sand is produced by passing boulders and stones through a series of jaw and cone crushers for size reduction and then fed into vertical shaft impact (VSI) crushers where they are pulverised further to the size of sand. The VSIs crush them to cubical and angular particles. Later these will be washed using wet means of Bucket wheel classifiers or Hydro cyclone supported washing systems to convert into exact sand removing the fine particles.

M sand is superior over the natural sand in the following specialities. Bond strength is more and thereby high strength for concrete and also by reducing segregation, bleeding, honeycombing, voids and capillary. The durability of concrete is increased as the sand is being manufactured from the granites which have balanced chemical and physical properties.  This helps the concrete structures withstand extreme environmental conditions and prevents the corrosion of reinforcement steel by reducing permeability, moisture ingress, and freeze-thaw effect. Workability of concrete is increased as M sand requires lesser water to be used as the shape and binding nature aids lesser use of water. Construction defects are reduced to a minimum like bleeding, hone combing, voids etc.

The major social perspective of the M sand-based construction is the Economic impact and the Eco-friendliness since the usage of M-Sand has increased durability, higher strength, reduction in segregation, permeability, increased workability, decreased post-concrete defects, it proves to be economical as a construction material replacing river sand. It’s cheaper, Transportation is easier and local based production throughout the season is possible. Usage of manufactured sand prevents dredging of river beds to get river sand which may lead to environmental disaster like groundwater depletion, water scarcity, threat to the safety of bridges, dams etc. to make M-Sands more eco-friendly than river sand.

Hailstone since its inception in 1995 is an active stakeholder in the M Sand industry. We are one of the leading OEM and EPC involved in M sand units and sand production projects. Out Sand washing machines Bucket wheel classifiers and Hydrocylcone based ADDWASH are the most sold of its kind in India. Being the leader in this segment our commitment towards the society was unconditional and we always focused on our goal of “Transformational growth for sustainable development”.

Hailstone also added another golden feather to the glory by carrying out the first patent EPC project of sea sand dredging and converting it into the usable form for construction in Kerala.  This iconic project also adds value to the new segment of manufacturing sand from natural resources by improvising the quality and parameters using technology for today's need.

Apart from the sand washers, we have an impressive product line of machines starting from Jaw crushers, cone crushers and VSI machines which are a key part of the total projects for conversion of rocks and granites into Sand. Specifically for some markets where there is water scarcity for the fines removal we are happily helping our customers with Air classifiers which help in removing the fines from Sand. All our customers are overwhelmed with our equipment due to the superior quality of the machines as well as the product sand which is being produced. Hailstone makes Equipment produced sand as always impressively clears the IS Standard testing and all sieve tests and is a common brand being used in all major projects. The trust and empathy of our entire customer towards Hailstone machines and the incomparable services and product quality make us a renowned Brand in M Sand Industry.
