Lancaster Products has deep experience blending, mixing and pelletizing materials in the ceramics industry. Our High Shear Counter-Current Mixers excel in homogenizing powdered materials of different densities. Lancaster Products Mixers provide high-intensity mixer preparation of glazes for ceramics.
Our mixing action produces reduced process times and improved productivity, and produces a more homogeneous solution for glazes and other applications.
- Granulation of the raw material for improved quality and strength for pressed tile.
- Preparation of the slip for use in the casting process for sanitary ceramics and technical ceramics.
- Preparation of plastic bodies for extrusion and formable bodies.
- The ability to prepare the dry raw materials and the plastic body in a single mixer.
- Excellent distribution of additives even in very small quantities.
- Simple corrections in moisture when required.
- Reduced processing time allows higher throughput from a smaller machine.

Lancaster Mixers provide high intensity slip preparation for castable shapes. Our mixers result in reduced processing times versus the standard preparation in a blunger. Reduced aging times for the slip occur because of the high shear and desalination of the clay particles during processing. This results in the ability to cast the slip immediately after preparation without the typical 8-12 day aging period.
Lancaster Mixers are used extensively in ceramic proppant preparations that include the mixing of raw materials and the graduation of the materials for green pellet production. This process can be completed with clay-based proppants, fly ash based proppants and many other materials that can be fired into a final proppant product.

This is the third video in our lab and testing series. The Lancaster Products Lab is equipped with a production-sized K4 mixer to test and optimize mix recipes at full scale. In this video, we are testing a clay type of material for pelletization.
The K4 mixer introduces a third tool, the low-speed plow, which, along with the rotating pan, transports material to the high-speed rotor. You can see how the high shear counter-current movement creates a rolling action which agglomerates the materials into pellets. The K4 mixer has a bottom discharge; the plow allows for the rapid and complete evacuation of the mixing cavity. After the mixer is fully evacuated, the bottom discharge closes, and reseals ready for the next batch.
This is the second video in our lab and testing series. The Lancaster Products lab is equipped with a small production-sized K3 mixer to test and optimize mix recipes at a prototyping scale. In this video, we are testing a clay type of material for pelletization.
Looking inside of the mixing cavity, you see the counter-current mixing action. The pan rotates clockwise, and the high shear mixing tool spins counterclockwise. The mixing pan actively transports material to the primary mixing tool. Slowing the action down gives us a good view of how the Lancaster mixing action creates a tumbling that promotes agglomeration by rolling the particles much the same way as a snowball growing larger by rolling down a hill.
