DLH Small Ribbon Mixer
- Product details
Product Overview
The DLH Small Ribbon Mixer uses inner and outer ribbons in a horizontal vessel to create convection and shear mixing. The inner ribbon moves material from the centre toward both sides while the outer ribbon moves material from the vessel wall toward the centre. The mixer is designed for pilot plants, small production lines and flexible batch sizes.
Applications
It is used for food additives, pesticide powders, veterinary medicines, building materials, chemicals, biological products, aquaculture, ceramics, refractory materials, plastics and compound fertilizers. It can mix powders, granules, cohesive materials, powder-liquid additions and powder-paste blends. It is also suitable for materials such as putty, textured coating and metal powder when the correct configuration is selected.
Working Principle
The opposing inner and outer ribbon flows form continuous convection and shear circulation throughout the vessel. This allows material to reach a uniform blend in a short cycle while reducing segregation. Scrapers can be installed for sticky materials, and a liquid spray system can be added for powder-liquid mixing.
Structural Features
Horizontal vessel with stable operation, low noise and convenient installation and maintenance.
Different ribbon and agitator structures are available for different material behaviour.
Optional scrapers for cohesive or sticky materials.
Optional chopper, liquid spraying, heating and drying jacket.
Cleaning doors and customized feeding, inspection and vent openings can be added.
Overall equipment height can be kept low for easier installation.
Product Advantages
Wide application range
The mixer can handle powder-to-powder, powder-to-liquid and powder-to-paste blending. Its configuration can be adapted to viscous, high-density, fragile and fine-powder materials.
Stable drive and reliable discharge
A K-series helical bevel reducer can be selected for high output torque, low noise and long gear life. The discharge valve can be designed to fit the vessel profile, reducing dead zones and improving sealing performance.
High loading rate and strong sealing
According to material properties, the vessel can be designed with a 180°–300° working section and a maximum material loading rate of approximately 70%. Gas-tight and packing composite seals can be used for ultrafine powders, while mechanical seals are available for free-flowing slurries.
Non-standard customization
Options include liquid spraying, explosion-proof configuration, heating, vacuum, carbon steel, SS304, SS316L, polyurethane lining, wear-resistant coating and customized valve designs such as butterfly, flap, ball and star valves.
Small Production Line Integration
The DLH mixer can be integrated with feeding, conveying, screening, liquid dosing and discharge equipment for a compact powder processing line. The layout and interfaces can be designed around your material flow and available installation space.

Determine the material volume required per batch and choose the initial working volume.
Select contact and non-contact materials according to corrosion, hygiene, temperature and wear requirements.
Confirm bulk density, particle size, flowability, viscosity and starting conditions for drive selection.
Add liquid spray, heating, cooling, vacuum or chopper systems according to the process.
Define feeding, inspection, cleaning, venting and access openings.
Select manual, pneumatic or electric discharge and the required sealing configuration.
Selection note: The listed volume is based on powder with bulk density 1. Actual selection must be calculated from your material properties, batch size, target cycle time and process requirements. Send these details to receive an engineering recommendation.
