The working principle and technical characteristics of the drum granulator for processing fertilizers

 With the development of agriculture and the improvement of technology, the market demand has begun to become diverse, and the rotary drum granulator has also attracted attention because of its high efficiency and convenient operation. Different from the traditional pelletizing process, when the lining of the rotating strand pelletizer moves from the bottom to the top of the cylinder, the lining sags due to the relationship of self-weight, and the material attached to the lining falls due to gravity, which achieves the role of automatic cleaning of the aggregate. In the process of producing fertilizer, the conversion granulator is the key to determining the yield and quality of fertilizer, the quality of organic fertilizer equipment is directly related to the user's economic benefits, the conversion granulator in the production process to increase the solubility of granulation by increasing the temperature of the material, to reduce the thermal energy consumption in the drying process we must effectively ensure the performance of the granulator. To reduce production costs, it is necessary to achieve low energy consumption and rate in all aspects of the organic fertilizer production line, and the pelleting rate should be high, so that the output can keep up. To ensure the pelleting rate, the inner wall finish of the pelleting machine should be improved, and the smooth material on the inner wall of the equipment can roll back and forth and quickly form a ball. There is also a reduction in the addition of water during granulation to reduce the drying load.

The rotating drum granulator of bio organic fertilizer equipment includes a frame, on which a drum is provided, on the inner wall of the drum are provided with a plurality of sliding grooves extending along the axial direction of the drum, on the inner wall of the drum are also provided with a plurality of rubber pads, the opposite sides of the rubber pads extend into the adjacent sliding grooves, and a sliding limit device is provided between the sliding groove and the rubber pad. The cylinder wall of the drum is provided with a guide hole, and the guide hole is equipped with a limit rod, An elastic clamping device is arranged between the limiting rod and the drum; The rubber pad is equipped with a counterweight, which is located between the rubber pad and the roller; During the rotation of the drum, the rubber pad rotating to the upper part moves downward under the action of the counterweight against the action of the elastic clamping device. When the limit piece is clamped into the limit groove again, the limit piece is clamped in the limit groove to prevent the downward movement of the rubber pad. The downward movement of the rubber pad is suddenly stopped, forming the effect of rubber pad shaking, effectively preventing the slurry from adhering to the drum and improving the granulation efficiency.
