Processing technology of organic fertilizer by drum granulator
Drum granulator is designed and manufactured by a new process of wet continuous push rod granulation. By using the high-speed rotary mechanical stirring force and the resulting friction, the fine powder materials are continuously mixed in the granulator, granulating, spheroidizing, densifying, polishing and other processes, so as to achieve the goal of granulation. It is suitable for direct granulation after organic fertilizer fermentation, saving drying process and greatly reducing manufacturing cost. It is a special equipment for producing compound fertilizer and compound fertilizer, also called compound fertilizer equipment, compound fertilizer production equipment, etc. The organic fertilizer granulator machine is a kind of equipment which uses chicken and pig manure as the main raw materials, adds a certain amount of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate and other substances, ferments rice bran, yeast, soybean meal and sugar for a certain time as biological bacteria, and produces biological fertilizer by mixed fermentation under the action of sulfuric acid. It is suitable for pelletizing peat, sludge, chicken manure, livestock manure, lignite, filter sludge of sugar factory, paper sludge, distiller's grains, straw, soybean residue and other raw materials.
Working principle of rotary drum granulator for organic fertilizer
The belt and pulley are driven by the main motor. It is transmitted to the driving shaft through the reducer. The split gear installed on the driving shaft is meshed with the big gear ring fixed on the body and works in opposite directions. The material is added from the feeding end and passes through the inside of the cylinder. Through the function of the special structure inside the cylinder, it is made into particles and flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of granulator, mass production can be realized.
