How to control water content to increase the output of fertilizer disc granulator

2020/12/30
Disc granulator is the core equipment of organic fertilizer making machine, which directly affects the quality and output of pelletizing. The quality standard of fertilizer ball: the diameter of the ball is 1-4.75mm, and the surface is smooth.

How to increase the output of disc pelletizer?

One of the main ways to increase the output of the disc granulator is to control the water content of the granulated particles.
1. According to the characteristics of the powder: composition, fineness, viscosity, humidity, temperature, etc., the water content of the particles should be controlled at about 30-28%.
Too little water content, difficult to form balls, low output;
Too much water content, too many large balls, the ball surface is sticky, easy to block the screen surface;
Proper water content, more balls, and high output.

2. How to test the water content of granules in the production process: a simple and practical method -- hand feeling method: grasp a handful of materials that have been balled from the disc granulator by hand, hold them in a ball, and release them with a touch of fingers. In this way, more grains are produced, the yield is high, and the screen surface is not easy to be blocked.
