With the development of organic agriculture, the diversification and high moisture content of organic fertilizer raw materials (such as straw, livestock and poultry manure, and mushroom residue) have driven technological upgrades in new type organic fertilizer granulators. Their optimized design, tailored to the characteristics of these raw materials, has significantly improved production efficiency and the quality of the finished product.
The new type organic fertilizer granulator features a new raw material conditioning system and an anti-sticking device. The conditioning system precisely controls the addition of steam or warm water to adjust the high-moisture organic fertilizer raw materials to a suitable moisture content for granulation (40%-50%), preventing clumping and loose granules. The anti-sticking device sprays a special wear-resistant coating on the inner wall of the granulation chamber, reducing the stickiness of the organic fertilizer raw materials and reducing cleaning frequency.
In terms of workflow, pre-treated organic fertilizer raw materials first enter the conditioning system for humidity and temperature adjustment before being transported to the granulation chamber. The spiral or extrusion mechanism within the granulation chamber mechanically compresses the raw materials into granules. The granules are then trimmed to a uniform size by a cutting device before entering a cooling system for final shaping.
The core value of the new type organic fertilizer granulator lies in its ability to efficiently process highly viscous and high-moisture organic fertilizer raw materials. The resulting granules are high in strength and water-solubility, while also reducing raw material waste. This equipment provides support for large-scale, high-quality production in the organic fertilizer industry.
