The influence of material moisture on organic fertilizer granulator is mainly reflected in the following aspects:
1. Impact on granulation process: When the material moisture is in the appropriate range, it can improve the granulation efficiency, enhance the bonding force between material particles, promote particle forming, reduce the breakage rate, and reduce the risk of ring die hole blockage.
2. Impact on equipment life: Materials with too high or too low moisture content will increase the wear of organic fertilizer equipment. During the extrusion process, high-moisture materials evaporate to produce steam, increase the volume of materials, and increase the risk of blockage; low-moisture materials accelerate equipment wear due to high friction. High-moisture materials are prone to form a humid environment inside the equipment, causing rust and corrosion of equipment parts, affecting the service life of the equipment.
3. Impact on product quality: Appropriate material moisture helps to produce organic fertilizers with uniform particles and qualified strength. Too high or too low moisture content will affect the strength and appearance quality of the particles. For example, particles produced by high-moisture materials are fragile and have a rough surface. The appearance quality and strength of the particles directly affect their commerciality. Appropriate material moisture helps to improve the commerciality of the particles and meet market demand.
5. Moisture control strategy: Through moisture detection, establish a raw material moisture content database to record the initial data of different batches and types of raw materials. According to the moisture adaptation range of different granulation equipment, select appropriate equipment and process parameters, such as extrusion granulator is suitable for low-moisture materials, and disc granulator directly humidifies through steam pipes.
