Improving the molding rate of the new type two in one organic fertilizer granualtor requires optimization in four aspects: material pretreatment, parameter matching, equipment maintenance, and process linkage, which is effective and stable.

First, strictly control the basic conditions of the materials: adjust the moisture content to 25%-35%; too dry materials are prone to pulverization, and too wet materials are prone to sticking and clumping; homogenize the raw materials in advance using a horizontal mixer to ensure no large clumps and uniform nutrient distribution, and add an appropriate amount of binder (humic acid, bentonite) as needed to enhance cohesion.

Second, precisely match the granulation parameters: adjust the main shaft speed, roller pressure, and die plate gap according to the material characteristics to avoid material scattering due to excessive speed and loose molding due to insufficient pressure; select a die plate/mold with a suitable aperture to ensure smooth discharge without clogging.

Third, ensure key maintenance of the fertilizer making machine: regularly polish and replace worn roller skins and die plates to maintain a smooth working surface; clean sticky and accumulated materials to prevent clogging and resulting in irregularly shaped granules; check bearings and transmission components to ensure smooth operation without vibration or deviation.

Fourth, optimize the linkage of the front and rear processes: ensure continuous and uniform feeding and mixing in the front end, eliminating material interruption or uneven feeding; the rear end should be equipped with low-temperature drying and cooling to prevent granule cracking due to heat; control the return material ratio, and re-mix the qualified return material for granulation to improve the overall molding rate.

The above measures can significantly reduce problems such as pulverization, wall adhesion, and failure to form granules, stably improving the strength and molding rate of the finished granules, and are suitable for large-scale production of organic fertilizers and organic-inorganic compound fertilizers.
