Many of the mix requirements presented to our engineers start with the need to blend powders of dissimilar properties into a homogeneous mix.  It’s not uncommon for customers to discover that the equipment they currently use or are considering for use either does not produce the level of homogeneity specified or the process takes too long.  We take great pride in seeing their faces light up when we show them the results that can be achieved using a Lancaster Products High Shear Counter-Current mixer!

Vastly differing densities of powders can present unique problems when attempting to achieve a desired homogenous mixture.  In particular, we have experienced this in the technical ceramics industry where the key ingredients often have dissimilar densities.  The issue is further compounded in cases where the ratio of ingredients can be significantly unbalanced with 95% of the mixture containing ingredient “A” and the other 5% consisting of ingredients “B, C, D…”.

It is critical that all specifications for homogeneity are met during the initial blending stage to avoid compounded issues in subsequent processes such as curing and extruding.  Even minor ‘imperfections’ in the mix can compromise the overall performance requirements of demanding end products such as technical ceramics or precision flat panel glass.

Alternative equipment such as double-cone or “V” type blenders can often achieve a homogenous mixture, but clients have come to us with several cases where the time and energy imparted into the mix are outside of the scope for what is deemed a “productively efficient” process.

The process employed by counter-current, rotating pan high shear mixers from Lancaster Products is perfectly equipped to satisfy the critical specifications demanded in technical ceramics manufacturing processes as well as in other applications that call for homogenous mixes of dissimilar powders.  What’s even more impressive is that we’ve worked with customers to formulate repeatable processes that cut their mix times down to as little as 3 minutes per batch.  The Lancaster High Shear Counter-Current mixer is the ideal machine to consistently deliver homogenous mixes of the most difficult powdered ingredients in relatively short batch times.

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.
