Lancaster Products K1-Lab Mixer: A new dimension to your mixing and pelletizing process.

The Lancaster Products K1-Lab Mixer is our flagship product used for testing, experimentation, and development of new processes and products. An economical and rugged machine, the K1-Lab Mixer can also be used for small production work. The K1-Lab Mixers have repeatedly proven to be a minimal investment with maximum dividends in product development.

Mechanical Design Features

  • Removable stainless steel mixing pan with 0.5 cu.ft. capacity for easy clean up
  • Large viewing port on the pan cover for adding process materials, observing the mix, and taking samples during the mixing process.
  • Touch screen control on independent control stand
  • Thermocouple mix temperature reading
  • Dual hand safety buttons for operating mixing head

OPTIONAL FEATURES: pan heating and cooling, various rotor styles


Lancaster Products Lab Mixer

The K-1 Lab Mixer not only provides value during proof of concept testing but throughout the entire product development and production process. Scaling up to production sized volumes is seamless as the Lancaster K3-10 Series mixers operate with the same counter-current high shear mixing action as the K-1 Lab mixer. This allows for efficient transfer of process specifications requiring only minimal adjustments to the mix design. In addition, the K-1 Lab Mixer facilitates the ability to optimize formulations and experiment in smaller batches, without having to disrupt production for development work or waste large amounts of material from experimenting in a K4-K10 sized mixer.

Lab Mixer

The K1-Lab Mixer has the same counter-current mixing design as all Lancaster Mixers with the clockwise rotating pan bringing material into the counterclockwise high speed rotor. The rotor and pan speed are infinitely variable.

This mixing design provides not only improved mix quality but can pelletize in one process step. In addition, processing times can be greatly reduced while providing a more homogeneous batch.

These features, combined with the rugged construction and the various styles of rotors available, make the Lancaster K1-Lab the mixer of choice for almost any type of batch mixing.


The K1-Lab Mixer is designed with a touch screen control for easy programming and data viewing. A thermal probe gives a report of temperature in real-time. There is a resettable elapsed mixing timer that provides for total mix process cycle times. A pre-programmable mix design can be input into the control. The control can also store and repeat mix cycles as well as communicate with other devices.


  • Electronic individually controlled speeds of pan and rotor, switchable from ft/sec to m/sec.
  • Timer that starts/stops with the machine.
  • Pre-programmable mix design times
  • Input or adjust pan and rotor speeds before or during operation
  • Data record of operating functions can be exported to a USB or other device
  • Pan heating and cooling available.

Operational Life Expectancy of Lancaster High-Intensive K-Series Mixers

Lancaster Products High Shear Counter-Current Mixers are highly effective in their ability to mix and pelletize in one machine and one process, but Lancaster Mixers are also built to last. Many of our machines are still operating after decades of use. We continue to supply parts to many vintage year machines still in operation.

High Shear MixerLancaster Products machines are built with a robust construction that provides structural durability and are designed to allow for replacement of wear parts as needed to extend the operational life of our machines instead of total machine replacement. To our customers this translates to lower Total Cost of Ownership and higher return on investment than other mixers. With proper maintenance, Lancaster Products mixers are very long-lived machines.
