Heavy-Duty Dual Shaft Mixer for Precise Fertilizer Powder Humidification

Product Overview

Our Dual Shaft Mixer is an industrial-grade solution designed for the precise humidification and homogeneous mixing of dry, powdery raw materials in fertilizer production. It transforms powders into uniformly moistened, pre-agglomerated material ideal for downstream granulation. By combining controlled liquid addition, intensive mixing, and conveying in one machine, it streamlines production lines, enhances granule quality, and improves overall efficiency.

Key Features

• Efficient Dual-Shaft Mixing: Dual shafts with intermeshing blades ensure rapid, thorough homogenization.

• Controlled Humidification System: Integrated spray nozzles for precise, uniform moisture addition.

• Optimized Three-Zone Process: Dedicated zones for atomization, mixing, and discharge guarantee consistent results.

• Durable & Wear-Resistant: Blades made from high-grade, wear-resistant materials for a long service life.

• Combined Mixing & Conveying: Helical blade design gently moves material from inlet to discharge.

Technical Specifications

• Model Range: Batch capacities from 5 m³ to 50 m³.

• Shaft Drive: Dual independent motors with heavy-duty reducers.

• Mixing Blades: Helical design, wear-resistant, replaceable.

• Spray System: Stainless steel nozzles with regulating valves.

• Construction: Carbon steel main housing; stainless steel (304/316) contact parts optional.

• Control: Manual or automated PLC-based control for moisture and mixing time.

Working Principle

The operation follows a precise sequence within three distinct zones:

1. Atomization Zone: Dry powder enters, and pressurized water is atomized through nozzles, creating a fine mist over the powder.

2. Mixing Zone: The core area. Dual shafts with intermeshing helical blades rotate, vigorously folding and shearing the moistened powder to form uniform, moist agglomerates.

3. Discharge Zone: The homogenized material is gently conveyed by the blades to the outlet, ready for the next granulation stage.

Applications in Fertilizer Industry

• Raw Material Pre-conditioning: Humidifying and mixing base powders like phosphate rock and ammonium salts before granulation.

• Organic Fertilizer Production: Uniformly adding moisture and binders to fermented organic materials (manure, compost).

• Compound Fertilizer Blending: Ensuring homogeneous moisture distribution in NPK powder mixes for stable granule quality.

• Dust Control & Recycling: Agglomerating fine dust and recycled materials into usable feedstock.
