The Mineral Gypsum or Phosphors Gypsum is Screened for lumps. The lumps are crushed fine. The powder is mixed with the binder and hardener and transferred to the granulator. In the granulation drum a very fine spray of water is done on rolling material at its angle of repose. Some coating of powder over the small nuclei / particles takes place. The size of granules are controlled as More spray, bigger granule. Less spray small granule. This duration of this process is controlled as per requirement. The material is then taken to dryer drum where the hot air generated in the furnace is passed through it. The dried material is cooled in cooler drum by passing ambient air through it . The ID fans connected to dryer & cooler sucks air from the drums so some dust also comes with it. The dust is separated in the cyclones and finally scrubbed in wet scrubber. The cooled material is screened through under size & over size screens. The product of 1 – 4 mm size is separated and packed in 50 kg. bags. The oversize material after crushing and the under size are recycled and work as nucleus for next cycle . 

TSP (Triple Super Phosphate) represented as 0-46-0, is normally applied where plants are grown in soils with low or average levels of phosphorus. Its importance can be measured by the fact that in absence or it, the root development is weak, growth is stunted, and productivity drops, the leaves or the edges of the leaves turn purple and in plants like tobacco and cotton, the leaves turn an abnormal colour of dark green; potato tubers develop brown spots etc.

All our NPK production plants are competitively priced, and can be customized to meet the specific demands of the customers. The integrated design allow proper maintenance and cleaning. The dust in the system can be separated with cyclones and scrubbed with water. High production capacity, consistent performance and low energy consumption, option of using different fuels further makes our NPK production lines - the preferred choice of leading players in the fertilizer industry.

Manufacturing Process

The raw materials like Urea, DAP, SSP, TSP, Murate of Potash and fillers are fed to the weigh belts conveyors where they are weighed in specific quantities for the grade and moved to Mixer for producing homogenous mixture. The material is mixed with the recycle material and taken for granulation in granulation drum where the partial granulation is achieved with very fine jet of water spray at the rotating granules. The fine powder gets deposited on a small nuclei. This process can be controlled to produce particle size as per the demand of the customers. The material is taken to dryer drum where hot air generated in the furnace is passed through it. The raw material having low melting points easily melts and gets deposited on the nuclei. The high temperature evaporates water and the material is air dried. Further, the material is cooled by blowing ambient air through it in cooler drum. The 1 – 4 mm or desired size homogenous granules are obtained using vibrating screens. The product, screened granules of uniform size are precisely packed in bag. The oversize material (after crushing) and undersize are recycled.
