Low Shear – High Volume Mixers with Counter-Current Technology.
Lancaster Products L-Series counter-current mixers are equipped with hi-torque, low shear, rotating plow blades. The L-Series mixer can come with muller wheels as an option, which combines a kneading, rubbing, or smearing action of a mortar and pestle along with the intensive mixing of the counter-current system. L-Series industrial mixers can be manual, fully automatic or a combination of both and can be used for research, testing or production.
Lancaster L-Series Mixers are ideal for:
- Low shear or low energy mixing
- Suitable for Shear Thickening or Non-Newtonian materials
- Mixing, slow or delayed chemical reactions
- Capacities from: 0.1 cu ft to 80 cu ft
TOOLING OPTIONS
Lancaster Products engineering staff can assist in selecting the appropriate mixing tools depending on the characteristics of the materials to be processed.
Low Shear tooling options include:
- Plow action alone, or plow with mulling wheels
- Fork tines or cutters can be substituted for plows
When mulling action is desired, the mulling wheels are adjusted above the mixing pan bottom to clear the largest grain size. This feature prevents particle size change or destruction.
HOW IT WORKS
The counter-current mixing action of the Lancaster Mixer is widely accepted as the most effective technique for consistent uniformity and thoroughness. Simply stated, counter-current action occurs when the pan rotates in one direction, while the mixing tools rotate in the other.
The rotating mixing pan conveys the material to the counter-rotating tool assembly. This results in countless cross-over of layers with maximum particle travel both vertically and horizontally, without depending on free fall.
Depending on the material and application, mulling can be an important addition to mixing. Equipping Lancaster Mixers with muller assemblies imparts a kneading and smearing action of a mortar and pestle needed for some applications such as foundry sands, along with the intensive mixing of the counter-current system.
LOW SHEAR MIXING APPLICATIONS:
Look to the Lancaster Products L-Series Mixer for advanced techniques for mixing solids or solids with liquids. Lancaster L-Series low-shear mixers can be adapted to process dusty, abrasive, corrosive, highly viscous or explosive materials and can be used for research, testing or production.
Lancaster Products L-Series counter-current industrial mixing equipment can handle materials from powders to pastes – regardless of differences in particle sizes, shapes, weights, and hardness.

Maintenance Bulletin: Rotor Wear and Replacement in Industrial Mixers
The high-speed rotor is the primary mixing and pelletizing tool in industrial high shear mixers and in many ways, it is the most utilized part of the machine. But rotor wear is also a good leading indicator of your machine’s overall operating condition as it is a direct result of material processing. Chances are, if the rotor is worn, there is other preventative maintenance to be done.
What Preventative Maintenance Will Prolong the Life of My Mixing Equipment?
Industrial mixers are built to run and withstand a great deal of abuse, however, regular preventive maintenance efforts can help keep your mixer running like new. The two most critical components that can affect the life of your mixer are lubrication and inspection of working tools. Below is an overview of the in-depth information provided in our full maintenance schedule available for download below.
Lubrication: Proper lubrication can encompass multiple areas on your mixer, not just the shaft seals of the mixing tool. Lubrication of all seals as well as drive gears, discharge valves and other locations where bearings are utilized is the best way to extend the life of your mixer. Automated lubrication systems on larger production mixers help maintain proper lubrication intervals, but regular visual inspection should be scheduled to assure the system is working properly.
