Materials are evenly fed into the machine through the feed inlet. The two sets of mixing blades simultaneously perform powerful shearing, pushing, and tumbling of the material. The forward-rotating blades gather the material towards the center, while the counter-rotating blades push the material to both sides. Under repeated staggered mixing, the raw materials form a tumbling and lateral convection flow within the machine chamber, allowing different raw materials such as manure, straw powder, humus, and mushroom residue to be quickly and thoroughly mixed.

During the mixing process, water or bacterial solution and binders can be evenly added through a matching spray device. The blades, while mixing, can also fully knead the water with the material, preventing uneven wetting. Compared to single-shaft mixing, the dual-shaft structure provides stronger mixing power, effectively breaking down and crushing high-fiber, high-moisture, and easily agglomerated organic fertilizer raw materials, preventing material from clumping and sticking to the walls.

After mixing, the qualified material moves slowly towards the discharge port under the continuous pushing action of the blades, and is eventually discharged smoothly. The entire operation is continuous and stable, with high mixing uniformity, ensuring consistent material proportions and laying a good foundation for subsequent granulation and fermentation processes. The equipment operates smoothly, with low noise, and is not prone to jamming, making it suitable for continuous mixing of various organic fertilizer raw materials.
