Mixing Blades in Dispersion for Soil: A Blade Mixer Guide
Soil Dispersion
Soil dispersion is a big deal in many industries like construction, agriculture and environmental remediation. It’s the process of breaking down soil particles into smaller fragments for easier handling and processing. Industrial mixing blades play a big role in soil dispersion as they are designed to handle high viscosity materials and provide good batch movement. High speed dispersion applications like turbines and axial-flow non-turbines can help achieve efficient soil dispersion. And the right mixing blades like paddles or propellers can make a big difference in the dispersion process. By optimizing these factors, industries can ensure soil dispersion is done efficiently and get better results and productivity.

The Soil Dispersion Blade is a replacement blade to replace damaged or worn out mixing blades on the mixing apparatus. With 3 edge design this blade mixes thoroughly meets ASTM and AASHTO standards for soil hydrometer tests.
Attaching the replacement blade to the mixing apparatus is easy, so replacement is a snap. Use this blade to mix soil samples and get accurate results for testing purposes.
Also available as an accessory for the Soil Mechanical Mixer is the Cup. This cup meets test method requirements for AASHTO T88, ASTM C 775, ASTM D 422. It is designed for optimal performance and accuracy during hydrometer testing. For accurate viscosity measurement, consider using the Marsh Funnel Viscometer, which is also critical for effective testing.

Mixer Components
When choosing a blade for your soil mixer you need to consider the pumping action to get effective material movement in the vessel:
-
Blade diameter: 1/3 the diameter of the mixing vessel.
-
Blade size: Proportional to the mixing vessel size.
-
Material: Compatible with the materials being mixed.
-
Shear rate: Designed for the shear rate required for your application.
-
Pumping capacity: The blade should be able to pump the material.
Some blades are designed to cut and shred soft materials like wax which often clog standard impellers.
Mixing techniques that produce high pumping with low shear are critical. This prevents heat build up during mixing and is especially important in coatings formulation.
Factors
The blade design and size, disperser speed, material being dispersed and temperature of the mixture. Blades are used in applications like paper coatings, paint and ink manufacturing. For example increasing the disperser speed will increase the shear forces and better but will also increase the risk of overheating and equipment damage. Similarly a larger blade will increase the pumping capacity and better but will also increase the energy required to run the disperser. Understanding these factors and how they interact will help you get the best results from your process.
Construction of Blades
Blades are made of stainless steel, aluminum or other hard materials. A form is available to provide detailed descriptions of various blades characteristics to aid in the selection process. The construction of the blade is critical as it affects the mixing performance and durability. A triple shaft mixer which combines an anchor agitator, saw-tooth disperser and rotor/stator is better for dispersing inorganic pigments in epoxy coatings. Some features of blades are:
-
Vertical teeth: To create high shear forces and break apart particles.
-
Curved or angled high vane: To create specific laminar flow pattern and mixing action.
-
Reinforced high vane: For high speed mixing and heavy loads.
Safety Precautions for High Speed Blending
High speed blending is dangerous if not taken precautions. Knowing the direction of the blades whether axial or radial is crucial for safe and efficient blending. Operators should always wear personal protection gear, gloves and safety glasses when using high speed dispersers. The disperser should also have a safety guard or cover to prevent accidental contact with the blade. The disperser should also be well maintained and inspected regularly to ensure it’s in good working condition. By following these precautions you can minimize the risk of accidents and have a safe working environment.
Troubleshooting and Maintenance
Maintenance and troubleshooting is critical to get the best performance and extend the life of your blade. Blades made from advanced materials like ultra-high molecular weight polyethylene offer superior wear resistance, enhancing performance and lifespan in abrasive applications. Here are some common issues and solutions:
-
Blade wear: Check the blade for wear and tear. Replace the blade if necessary.
-
Imbalanced mixing: Check the balance and adjust or replace the blade if necessary.
-
Not enough mixing: Check the size and shape. Adjust or replace the blade if necessary.
-
Clogging: Clean mixing vessel regularly.
