The working principle of the drum granulator
: the material enters the front end of the rotating cylinder from the feeding pipe (the slope of the feeding pipe should be greater than the natural inclination of the material). The steam inlet pipe at the front end of the cylinder ejects water vapor with a certain pressure. The nozzle of steam inlet pipe is located at the bottom of material. And the steam has a certain pressure. Therefore, the material can obtain some moisture evenly and form small particles. Because the cylinder has a certain slope. Under the action of gravity and friction force of lining plate, these small particles continuously move in the circumference and axis direction of the cylinder, and in the movement, the smaller particles gradually form particles of certain specifications.
The shell of the drum fertilizer granulator machine
is made of thickened carbon steel, and the supporting equipment includes tugboat parts, tugboats, transmission parts, wind head, wind tail, etc. The whole machine is solid and durable, not easy to deform. The base design of the drum granulator is stable, the operation is more stable, and the energy consumption is saved, which meets the requirements of environmental protection. Drum granulator can be customized to produce different specifications of the same type of equipment according to user requirements.
Features of drum granulator:
1. The pelletizing rate is up to 90%, there is a small amount of returned material, and the particle size of the material is small, which can be granulated again.
2. Through steam heating, the material temperature is increased, the moisture content of the material is low and the drying efficiency is improved.
3. The granulator machine for fertilizer
adopts special rubber plate lining or acid resistant stainless steel lining plate, so the raw material is not easy to stick to the cylinder, and has the function of anti-corrosion and heat preservation. It realizes automatic scar removal, tumor removal and cancels the traditional scraper device.
