Lancaster Products K-Series Mixers’ counter-current mixing action is the most effective mixing technique for consistent uniformity, homogeneity and rapid mix time.
Lancaster Products K-Series mixers are the ideal tool for the preparation of powdered materials. Their high intensive action allows for mixing even the most difficult of materials. Powders, slurries, and pastes (with or without water or binders) can be mixed in extremely short cycle times. Dissimilar powders, differing in density and/or ratio in a formulation, are easily blended into homogeneous mixtures.
The K-Series line of mixers excel in producing highly repeatable homogeneous mixes and pellets.

OPTIMIZE YOUR MIXING PROCESS
Whether you are developing a new process or looking to improve a current one, using a Lancaster Products High Shear Mixer can transform your mixing process. Our mixers can be used to achieve multiple objectives, including mixing cycle times, moisture and air entrainment, particle size distributions, yields, surface draw-down, pluming action, and tip speed requirements.
Processing times can be greatly reduced while providing a more homogenous batch (mix) using a Lancaster Mixer.
- Free-flowing powders & granular materials can reach the desired homogeneity within 1 minute*
- Mix-granulation applications are generally completed within a cycle of 6 minutes or less*
*based on results achieved in both lab and production environments
The counter-current mixing action in all Lancaster Mixers provides:
- Minimized quantity of additives used in formulations
- Reduced reaction times due to increased surface area and effective dispersion
- Consistent, repeatable mix quality from batch to batch
*Partial batches down to 1/3 rated capacity can be handled without affecting mix quality
THE MOST EFFECTIVE MIXING TECHNOLOGY
The Lancaster Products counter-current mixing action is the most effective mixing technology for rapid and consistent uniformity.
- Material is efficiently conveyed to the counter-rotating primary mixing rotor, secondary mixing plows and side wall scraper – all strategically placed to deliver maximum material mixing.
- Our design allows for increased relative particle velocities and provides countless material exchanges throughout each batch cycle
- Our High Intensive mixers allow for individually changing component speeds to add tremendous versatility in meeting almost and material mixing challenge.
WORKS WITH A VARIETY OF DIFFERENT MATERIALS
Lancaster Products high intensive mixers handle a full gamut of materials – from powders to slips and slurries, to taffy-like materials with viscosities exceeding 1,000,000 CP.
ALL IN ONE MACHINE
Blend, pelletize, Granulate, Slurry, Disolve, De-Dust and React – all in the same machine.
NO DEAD ZONES
There are effectively no dead corners or unswept surfaces where ingredients can lodge. The unique combination of rotating pan, side scraper, and counter-rotating plow effectively eliminates all dead zones.
Process times can be greatly reduced while providing a more homogeneous batch. Our experience in both lab and production environments is that free-flowing powders and granular materials can reach desired homogeneity in under a minute.
In most cases, because the Lancaster counter-current mixing action is so thorough, less binder materials or water is required.
CONTINUAL MATERIAL REMOVAL
The plow and side scraper also provide for continual material removal from the pan bottom and sidewall surfaces.
CUSTOM MIXING DESIGN
Lancaster Application Engineers design toward many goals, including: mixing cycle times, moisture and air entrapment, particle size distributions, surface draw-down, pumping action and tip speed requirements.
The intensity and type of mixing action can be controlled through the use of various style mixing rotors and speeds. Our technology coats pellets, de-fibers, de-lumps, fluffs and slurries..
K-Series High Shear Mixers
HORIZONTAL PAN DESIGN
Vertical axis horizontal pan mixing is the preferred design of the Lancaster Mixers. This positive and very efficient design of the pan gear drive ensures that the maximum amount of energy output is imparted into the mixing action. Pan rotation speeds can also be calculated for maximum material process effect without requiring higher speeds to move material to a higher elevation for proper mixing. The horizontal pan provides maximum production volume while minimizing contamination of the upper pan seal. The corresponding horizontal surfaces of our Lancaster Mixers provide easier and more efficient maintenance of the equipment.
The slow speed plows of the horizontal design of our Lancaster Mixers not only enhance the mixing process, but they also provide for continual cleaning of the pan bottom and assist in material discharge. The actions of our plows eliminate the duties of cleaning and discharge by a rotor and a stationary bottom scraper.
The primary mixing element of all Lancaster Products K-Series mixers is the single piece counter-rotating high-speed rotor. The design of the mixing rotor will vary depending upon the particular process requirements.
The single piece base rotor construction helps maintain rotor balance after blade replacement. The rotor is driven by an easily accessible V-belt drive system. The drive motor can be single speed, multiple speed, or variable speed depending upon specific processing requirements. The drive guard fully encloses the top portion of the motor and the rotor spindle.
A high-quality gear-motor drive is mounted on top of the mixer structure. This unit turns the slow speed secondary mixing plows. These wear-resistant plows continually sweep the entire surface of the pan bottom.
This efficient slow-speed sweeping action prevents material from accumulating on the pan bottom and also provide enhanced mixing action and faster mixer discharging.

Our last post focused on our experience in concept testing and how it applies to our high shear mixer sample testing process. This post will dig in a little deeper and provide insight into the breadth of data we provide to our customers when they commission Lancaster Products to provide sample testing for them.
Over the past 30 years, we have collaborated with our customers to perform proof of concept testing in our K1 laboratory mixers for thousands of materials samples. The desired outcome of the testing is customer dependent but typical requirements are along the lines of pelletizing/granulating to specific size ranges and desired yields, mixing to achieve homogenization, or reduced reaction times of existing processes. Outcomes provided are 1) proof of concept in achieving the desired product, and/or 2) optimization of the current mix processes. Our engineers perform the tests in our controlled laboratory, log all key information in our database, and share all data with our customers for future reference. Below is a list that summarizes some of the information we collect during every test run we perform:read more
