The particle shape of disc granulator is spherical, the particle size is generally between 0.3-5 mm, and the ball forming rate is more than 95%. The size of particle diameter can be appropriately adjusted by material mixing amount and spindle speed. Generally, the lower the mixing amount is, the higher the speed is, and vice versa. Due to the high ball forming rate, fertilizer granulator machine price concessions, stable operation, strong and durable equipment, long service life, it is selected as the ideal product by the majority of users.
How to improve the granulation success rate and granulation quality of disc granulator.
1. Selection of raw materials. The adhesion degree of different raw materials is different, so when choosing organic fertilizer raw materials, we should pay attention to the collocation of raw materials with different adhesion degree, which can improve the success rate of granulation and granulation quality. In special cases, we can use an appropriate amount of adhesive.
2. The grasp of moisture. The water content of raw materials is one of the main factors affecting the success rate of granulation and granulation quality. If the water content is too low, the difficulty coefficient of granulation will increase; if the water content is too high, the viscosity of raw materials will increase, the diameter of particles is easy to be too large, and the difficulty of drying behind will increase. Therefore, the moisture content of raw materials should be moderate. According to the basic data, the moisture content of raw materials for disc granulation should be between 25% – 30%.
