Drum granulator is a device that can shape materials into specific shapes. The rotary drum granulator is one of the key equipment in the compound fertilizer industry suitable for cold and hot granulation and large-scale production of high, medium, and low concentration compound fertilizers. The main working method is wet granulation. By adding a certain amount of water or steam, the base fertilizer undergoes a chemical reaction after being humidified in the cylinder. Under certain liquid phase conditions, material particles aggregate into balls under the action of extrusion force through the rotational motion of a cylinder.

This fertilizer equipment is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic pit and tumor removal and eliminating the traditional scraper device. This machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and easy operation and maintenance.

A rotary drum granulator is equipped with steam and other chemical substances to complete chemical reactions and heat the granulation process of compound fertilizer inside the rotary drum; Or the cold granulation process of adding a small amount of water to compound fertilizer. The material to be granulated rolls and rotates through the rotation of the cylinder when there is no material inside, and aggregates into balls at a certain humidity and temperature to complete the granulation process.

Characteristics of drum granulator for fertilizer equipment:

1. The ball making rate is 70%, with a small amount of small particle size returns that can be re made into balls;

2. Steam heating is introduced to increase the temperature of the material, making it a low moisture ball and improving the drying efficiency;

3. The inner lining is made of rubber engineering plastic, and the raw materials are not easy to stick to the cylinder, which plays a role in anti-corrosion and insulation;

4. High output, low power consumption, and low maintenance costs.
