N : Urea, Di Ammonium Phosphate, Ammonium Chloride, Ammonium Nitrate, Ammonium Sulphate, Mono Ammonium
Phosphorous as P2O5 : Single Super Phosphate , Triple Super Phosphate, D. A. P. etc..
Potash as K2O : Potassium Chloride, Potassium Sulphate etc.
Bagging Material : HDPE bags.
PROCESS OF MANUFACTURING :
The raw materials required for a formula are taken in the multiple hopper with the help of front end loader. The formula weights are calculated and weighed quantities of the raw materials is taken from the respective hopper and fed on the conveyor belts. The conveyor belt discharges the material in the weigh hopper. As the quantity fixed for the batch is filled, the discharge valve opens and inlet valve closes. The material is collected in the Recovery hopper From the Recovery hopper the material is transferred to the batch hopper with the help of an Elevator. The Batch hopper discharges the material in the conical Mixer. The Raw materials are mixed for a set time and discharged in a vent hopper.
The material from the Vent hopper is transferred to product hopper for packing. The product is packed in 50 Kg bags.
