Dual Shaft Mixer

Brief Introduction

TONY Dual Shaft Mixer is used for raw material pre-mixing and moisture adjustment in biomass pellet production line. Two counter-rotating shafts with alloy paddles create 3D convection mixing, to blend wood powder, straw powder and other materials evenly. Optional atomizing spray system for precise moisture control. The tank body can be hot-dip galvanized to resist moisture and organic acid corrosion from biomass materials. Fully enclosed structure with dust removal port, variable frequency drive and overload protection. Continuous feeding & discharging, easy to connect with other equipment in the pellet line.

TONY Dual Shaft Mixer suitable for biomass powders such as wood powder, bamboo powder, straw powder, palm fiber, peanut shell powder and nut‑shell powder. It can also be used for mixing and blending organic‑fertilizer raw materials and feed powders.

Note: Large‑size materials shall be crushed in advance. Materials with excessive particle size are not suitable for direct feeding into the mixer.

Working Principle

The dual shaft mixer is a horizontal continuous mixing device for biomass pellet production. It uses two parallel shafts rotating in opposite directions with wear-resistant alloy paddles. As the shafts run, the paddles continuously lift, tumble and push raw materials inside the tank, forming a three-dimensional convection circulation. This structure effectively breaks up material lumps and mixes different biomass powders evenly without dead corners. During the mixing process, materials move steadily from the feeding inlet to the discharge outlet to achieve continuous operation. The optional atomizing spray system sprays uniform water mist to adjust material moisture, keeping raw materials in the best condition for pelletizing. The fully enclosed body reduces dust pollution.

Equipped with overload protection and variable frequency control, the mixer avoids jamming damage and adapts to different feeding speeds. Finally, uniformly mixed and moisture-stabilized materials are delivered to the silo and pellet machine for further processing.

Main Parts

1.Main Tank Body: Horizontal U‑shaped tank, optional hot‑dip galvanized treatment for superior corrosion resistance. Inspection hatches can be arranged on the top of the tank for material observation and paddle maintenance.

2.Dual Mixing Shafts + Alloy Paddles: Two parallel main shafts fitted with high‑chrome alloy paddles featuring excellent wear and impact resistance. The two shafts rotate synchronously in opposite directions to drive materials into convective tumbling motion.

3.Drive System: Consists of motor and reducer; variable‑frequency drive is optional. An overload protection device automatically shuts down the unit upon material jamming caused by hard impurities, safeguarding main shafts and paddles.

4.Inlet & Outlet: Top feeding inlet and continuous bottom end discharge outlet, which can be directly connected to conveying equipment.

5.Sealing & Dust‑removal Port: Adopts fully‑sealed tank structure. Reserved dust‑removal interface collects dust generated during mixing.

Parameter

What Are The Application Areas?

1.Biomass pellet industry: Mix wood powder, bamboo powder, straw powder, palm fiber and shell powder. Adjust raw material moisture to stabilize pellet forming.

2.Organic fertilizer industry: Blend organic materials, auxiliary powders and additives for fertilizer granulation.

3.Feed processing industry: Mix various feed raw materials evenly to improve feed quality.

4.New energy and solid waste recycling: Mix agricultural residues and crushed waste materials for reprocessing.

5.Building material industry: Mix powder raw materials for lightweight materials.

Features

Specifically, The Advantages Of The Dual-Shaft Mixer Include:

‌Efficient Production: The Dual Shaft Mixer  adopts a continuous working mode, supports loading, mixing and unloading at the same time, and effectively improves the mixing production efficiency compared with conventional mixing equipment.

Stable Performance: The mixing device made of alloy castings is equipped with a high-power motor and a planetary reducer with high rated output torque to ensure stable operation of the equipment.

‌Environmentally Friendly Design: The mixing and conveying process is carried out in a sealed space, which will not cause dust leakage, and is clean and environmentally friendly.‌

Wear-Resistant Material: The mixing blade is made of wear-resistant material and is specially polished to have high wear resistance.

Compact Structure: The whole machine has a compact structure, small space occupation, stable transmission, high reliability and low noise.

‌Versatility‌: Suitable for humidifying and loading fly ash or similar materials in thermal power plants, mines and other industries, effectively improving production efficiency‌.

Model Selection Key Points

1.Select model according to production‑line capacity: Match machine model based on the hourly output of the production line, to ensure sufficient material residence time inside the tank for thorough mixing. 2.Material selection: Hot‑dip galvanized tank is preferred for humid workshops and biomass raw materials. Alloy paddles must be adopted if raw materials contain abundant hard impurities. 3.Humidification requirement: Equip with the optional atomizing spray system when raw material moisture fluctuates greatly to stabilize moisture content.

4.Space and connection: Confirm on‑site installation space and verify the heights of material inlet and outlet for easy connection with upstream and downstream conveying equipment.

5.Working‑condition protection: Install supporting dust‑removal pipelines for heavily dusty workshops. Enhance overload protection if raw materials contain a large amount of hard substances.
