The know-how of the good quality of the finished pellets of the disc granulator!

The tips for the good quality of finished granules of the disc granulator:

First, the disc granulator controls the moisture content of the powder at about 28-30% according to the composition, fineness, viscosity, humidity, temperature and other characteristics of the powder.

1.Too much water content, too many balls, the surface of the ball is very sticky, and it is easy to block the screen surface;

2.How to preliminarily measure the volume of granulated water in the production process: the most simple and practical method is the hand feeling method: grab a material ball from the disc granulator, it can be a ball, and it can be released by touching it with your fingers. In this way, there are many particles, high output, and it is not easy to block the screen surface.

Second, strictly control the quality of various raw materials such as chemical fertilizers in accordance with the formula of organic fertilizers and compound fertilizers.

1.It is strictly forbidden to use iron blocks, stone blocks larger than 10mm, and wood blocks larger than 10mm for raw material discharging and feeding. There are not many quality indicators of rice bran and rice sand, which seriously affect the yield.

2.The powder particle size of organic fertilizer used as compound fertilizer is 70-90 mesh.

3.Do a good job in technical training to improve the technical quality and operational skills of workers.

Third, the working mechanism of the nozzle must be mastered when selecting the nozzle: According to the theory of fluid mechanics, it is proved that the greater the pressure, the smaller the through hole and the larger the droplet diffusion surface. Under the same pressure, the nozzle orifice is small, the droplet density is small; the nozzle hole is large, the droplet density is high.

1.The smaller (or larger) the feed droplet size, the lower (or higher) the yield.

2.The denser (or thinner) the feed droplets are, the more (or less) the feed liquid is, and the higher (or lower) the output is.

3.Generally speaking, B-type spherical screw or B-1 basic screw nozzle is the choice of disc granulator. A good blade, the particle size is uniform and beautiful, the blade material must be 16m, the blade is divided into two front and rear, and there is no gap between the two blades.
