When disc granulator produces compound fertilizer, there are many factors affecting granulation, such as disc diameter, disc speed, disk inclination, nozzle nozzle diameter, water content and so on. Generally, disc organic fertilizer granulator has a larger influence factor on the grain formation rate, and a larger influence factor on the grain compression strength, disc speed.
The test shows that the water content of the disc granulator in the organic fertilizer equipment has a great influence on the granulation rate and compressive strength of the particles. When the moisture of the material is controlled in the range of 16%-20%, there is a better granulation rate and particle compressive strength. Material moisture is too little, particle granulation rate is small, too much water, material is easy to condense into large pieces, particles bond together, resulting in reduced granulation rate. When the material moisture is too low, the particle compressive strength will increase with the increase of moisture content, which is conducive to improving the particle compressive strength. When the moisture content is too high, too much water will destroy the intermolecular force of fertilizer, so that the dried particles are prone to crack, resulting in the decrease of particle compressive strength.
Before the use of organic fertilizer disk granulator, test the best water and disk speed, disk inclination Angle, so that the production efficiency is high, the particle quality is good, and the raw material powder of disk granulation is finer, the granulation effect is better.
Using disc granulation to produce organic fertilizer and inorganic compound fertilizer has the characteristics of less investment, large yield, simple process flow and intuitive operation, and has good economic and social benefits.
