Horizontal Ribbon Blade Mixer: The Ultimate Solution for Powder Mixing

Precision, Efficiency, and Uniformity for Industrial Applications

In the world of industrial processing, achieving a homogenous blend is the foundation of quality manufacturing. The Grand WLDH Series Ribbon Blade Mixer stands as a market-leading solution designed to handle the complex mixing needs of the pharmaceutical, food, chemical, and building material industries.

Whether you are blending dry powders, granules, or mixing liquids into viscous pastes, our machine delivers consistent results. Often referred to as a Horizontal screw mixer, this equipment is engineered to reduce mixing time while ensuring that every particle is evenly distributed.

Key Features of the WLDH Ribbon Mixer

1. Superior Mixing Homogeneity

The carefully calculated angle of the ribbon blades ensures there are no "dead zones" within the U-shaped container. This results in a coefficient of variation (CV) that meets strict pharmaceutical and food safety standards.

2. Versatile Discharge Options

We offer flexibility to match your facility’s infrastructure.

Pneumatic Butterfly Valve: For automated lines, ensuring quick and clean discharge.
Manual Butterfly Valve: For cost-effective, manual control.
Turn-off Fan Discharge: Ideal for minimizing residue.

3. Robust Construction

The entire machine is constructed from high-grade Stainless Steel (304 or 316L available). The interior is polished to a mirror finish to prevent material adhesion, making it a true sanitary Horizontal screw mixer.

4. Enhanced Safety Features

Worker safety is paramount. Our units come equipped with a robust Guardrail (safety grid) beneath the cover. This prevents operators from reaching into the moving parts while still allowing them to monitor the process or add minor ingredients safely.

5. Liquid Spraying System (Optional)

Do you need to add binders, flavors, or oils to your powder? We can equip the top cover with spray nozzles to atomize liquid additives, ensuring they are evenly coated onto the granules without forming clumps.

Ribbon Blade Mixer

FAQS

1What materials can the Ribbon Blade Mixer handle?/b>

The Ribbon Blade Mixer is incredibly versatile. It excels at mixing dry powders (like spices, flour, coffee, chemical additives), granules, and particles with small amounts of liquid. It is also suitable for mixing viscous pastes and cohesive powders that other mixers struggle to move.

2How do I choose the right size mixer for my production?

You should look at the "Full Volume" and the "Loading Coefficient." The effective mixing volume is typically 40% to 80% of the total volume. For example, if you need to mix 400 Liters of product per batch, the WLDH-0.5 (500L Total Volume) or WLDH-1 (1000L Total Volume) would be appropriate, depending on your material density.

3 What is the difference between a Ribbon Mixer and a V-Blender?

A V-blender relies on gravity and is gentle, making it good for fragile granules. However, the Horizontal screw mixer (Ribbon type) uses mechanical force (the blades) to move material. This makes the Ribbon Mixer much faster and better suited for breaking up minor agglomerates or mixing cohesive sticky powders.

4What industries can use the Laboratory Powder Mixer?

The Laboratory Powder Mixer is suitable for pharmaceuticals, agriculture, and various other industries.

5Is the machine easy to clean?

Yes. As highlighted in our product details, the Grand WLDH series can be equipped with a fully opening cover. This gives your cleaning crew complete access to the U-shaped tank and the ribbons. For strict sanitary requirements (like GMP standards), we can polish the interior to a high-grade finish to eliminate bacterial harborage points.

6Can this machine be used for continuous production?

Standard Ribbon Mixers are designed for batch processing. However, if your process requires continuous output, Grand Machinery can modify the design to allow for continuous feeding and discharge, though batch mixing is generally recommended for the highest mixing precision.
