is a molding machine that can manufacture materials into specific shapes. Fertilizer production is generally divided into: wet organic fertilizer granulator, disc granulator, flat die extrusion granulator, drum granulator, counter roller extrusion granulator.
Today we will take a concrete look at the role of granulators in fertilizer manufacturing process
The wet organic fertilizer granulator is widely used for granulation of organic fertilizer. Due to the high granulation rate, stable operation, sturdy and durable equipment and long service life, it has been chosen by the majority of users as the ideal product. Working principle: The high-speed rotary mechanical stirring force and the resulting aerodynamic force enable the fine powder material to continuously mix, granulate, spheroidize and compact in the machine to achieve the purpose of granulation.
The disc granulator is suitable for organic fertilizer and compound fertilizer. The granulation disc angle adopts an overall circular arc structure, and the granulation rate can reach over 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency. The machine has the advantages of uniform granulation, high granulation rate, stable operation, sturdy and durable equipment, long service life, etc. However, due to its small output, it is generally suitable for small-scale production.
The working principle of the flat die extrusion granulator: the material is extruded to the bottom by the grinding wheel, then cut by the scraper, and then enters the secondary combination polishing and rolling once into the ball; the organic fertilizer extrusion granulator has a high ball rate and no The advantages of returning material, high particle strength, uniform roundness, low moisture content of the ball, and low energy consumption for drying.
When the drum granulator equipment is produced, the craftsman will add the uniform mixed raw materials into the drum granulator, and simultaneously inject steam, and complete the chemical reaction compound fertilizer granulation process in the drum rotating rotation. It can be applied to cold water granulation of compound fertilizer supplemented with water humidification. It is relatively advanced NPK fertilizer production
The roller press granulator is new generation granulation equipment developed by our company. It is produced by no drying and normal temperature process, with one molding, less investment in equipment, quick effect and good economic benefit. The complete set of equipment is compact, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation and convenient maintenance. The raw material has wide adaptability and is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry and feed, and the product has high granulation.
