Vertical Disc Mixer is a specialized mixing equipment widely used in organic fertilizer production lines, primarily for uniformly blending organic raw materials (such as manure, straw), microbial agents, additives, and other components.
The equipment features a vertical structure with a rotating disc at the bottom. Driven by a motor, the disc rotates at a specific speed (usually 15-30 r/min). Materials are fed from the top into the mixing chamber, and under the combined action of centrifugal force and the disc’s inclined angle, they move upward along the disc edge. Meanwhile, the built-in stirring blades break up agglomerates and push materials to circulate. The materials form a uniform mixing layer in the chamber and are discharged from the bottom outlet after reaching the required mixing uniformity.
- Mixing capacity: Single-unit hourly output ranges from 0.5 to 15 tons, suitable for small to large-scale organic fertilizer production lines.
- Disc specifications: Diameter 1.2-3.0 meters, inclined angle 30°-45° (optimized for material circulation).
- Mixing uniformity: Coefficient of variation ≤ 5% (meets national organic fertilizer mixing standards).
- Power requirement: 5.5-45 kW, matching the equipment’s processing capacity.
- Material of construction: Mixing chamber and disc adopt Q235B carbon steel or 304 stainless steel (for corrosion-resistant needs).
- High mixing efficiency: The vertical disc structure and stirring blade design shorten the mixing time to 3-8 minutes per batch, 20%-30% faster than horizontal mixers.
- Uniform blending: Effectively mixes materials with different densities (e.g., light straw and heavy manure) without segregation.
- Compact structure: Vertical layout occupies only 1/3 of the floor space of horizontal mixers, saving workshop area.
- Low energy consumption: Centrifugal circulation design reduces power consumption, with energy efficiency 15%-20% higher than traditional mixers.
- Easy maintenance: Simple internal structure, convenient for cleaning residual materials and replacing wearing parts (e.g., blades, liners).
- Organic fertilizer production: Mixing fermented livestock manure (sheep manure, chicken manure) with additives like humic acid, microbial agents.
- Compound fertilizer processing: Blending organic materials with chemical fertilizers to produce organic-inorganic compound fertilizers.
- Solid waste treatment: Mixing municipal sludge, kitchen waste with bulking agents (straw, sawdust) for subsequent fermentation.
