Production of ammonium sulphate fertilizer particles by double roller press granulator
Double roller press granulator is a granulation equipment for producing various substances such as ammonium sulfate compound fertilizer. The granulator has the advantages of advanced technology, small equipment, novel and practical, and is the main machine of NPK fertilizer production process.
Double roller press granulator can be combined in a single or multiple units, designed into a continuous, mechanized production line with an annual output of 3,000 tons to 30,000 tons. Double roller press granulator has low energy consumption and can be matched with the relevant NPK fertilizer production equipment. It adopts no drying process and is produced at room temperature. Fertilizer roller press granulator production line, continuously optimize the formula, the product is molded once, the product quality meets the requirements of technical indicators, especially for the rare earth ammonium bicarbonate compound fertilizer has better granulation effect. It can produce all kinds of special compound fertilizer with high, medium and low concentration. It is a new generation product of energy saving and consumption reduction in compound fertilizer industry.
The opposite roller extrusion granulator extrudes the material through two bearings with roller skin. In view of the poor wear resistance of the opposite roller of the pelletizer machine, the technical personnel of our plant improved and adjusted the key process and relevant technical parameters through many tests, enhanced the wear resistance of the opposite roller, and significantly increased the output of the roller press granulator. In the production process of granulator designed by our factory, the friction coefficient between the material and the counter roll is small, the temperature rise is low, the energy consumption is small, and there is no pollution.
