Double Roasted Granules


M/s. Pushpa J  Shah is bulk manufacturer of Double Roasted Granules. Our annual turnover in production is around 40000 Mt. We provide superior quality heavy metal & dust free granules. As per  traditional practice in India, granular agri inputs are highly preferred and  demanded by farmers. Due to its granular nature it can be broadcasted along  with regular dose of fertilizers.

Benefit

1) Have a high liquid holding capacity. It remains free flowing after   absorbing 15 to 20 % liquid.

2) It  acts as a preservative of active ingredients.  It saves the technical ingredients from the direct ultraviolet rays of sun.  Since it is inert, It does not react with the technical material.

3) It is made of natural mineral clay so it is  non-hazardous and non-alkaline material. 

4) After it comes in contact of water it releases the active ingredients slowly over a long period of time hence reducing the chances of wash out in heavy rain or water logging condition.

5) As it is roasted at 700 degree temperature, material becomes inert & sterile which is preferable for Microbial products as it prevents the chances of contamination and increases the shelf life. 

6) These granules are roasted using approved fuel like furnace oil & natural gas.

7) Formulated granules are advised to mix with seeds while sowing, this will enable slow release of active material in rhizospere which can boost initial growth

Versatile Applications Across Industries

Double Roasted Granules excel in a range of sectors, from foundry operations where high thermal stability is essential, to filtration systems and refractory linings that require robust, uniform grains. Their superior chemical and physical properties, including minimal moisture content and high crush resistance, make them equally suitable for use as construction aggregates, providing consistent performance and reliability.


Superior Quality and Performance

These granules are manufactured to strict quality standards, ensuring a purity level of at least 98% and precise grain size consistency. The finished product is odorless, visually uniform, and colored dark brown to black. Their ability to withstand harsh conditionssuch as high temperatures and acidic environmentssets them apart in industrial applications.

FAQs of Double Roasted Granules:


Q: How are Double Roasted Granules utilized in foundry and refractory industries?

A: Double Roasted Granules are primarily used as molding sand, backfill material, and refractory linings, where their thermal stability and mechanical strength prevent deformation or breakdown under extreme heat, ensuring consistent casting results and prolonged equipment lifespan.

Q: What process ensures the high purity and uniform size of the granules?

A: The granules are subjected to a double roasting process that eliminates impurities and enhances uniformity. This careful thermal treatment, combined with rigorous screening, guarantees a minimum purity of 98% and a controlled particle size between 24 mm.

Q: When is it recommended to use these granules for construction aggregates?

A: Double Roasted Granules are ideal for construction projects demanding high-strength, durable aggregates. Their crush resistance and low moisture content make them a preferred choice for structural fills and bases that must endure mechanical stress and varying environmental conditions.

Q: Where should Double Roasted Granules be stored to maximize their shelf life?

A: To maintain quality, store the granules in their original plastic or HDPE packaging, in a cool, dry area away from direct sunlight or moisture exposure. Proper storage conditions extend shelf life up to 12 months without loss of properties.

Q: What are the key benefits of using Double Roasted Granules in filtration systems?

A: Their consistent granular structure, low fines content (1%), and excellent chemical resistance make them effective filtration media. They help maintain flow rates, reduce channeling, and contribute to long-lasting filter performance without degrading quickly.
