High Shear mixers are used in a wide variety of applications in many different industries. Finding the right blend and being able to produce the same mix consistently is the key to success at Highwater Clays, a clay and glaze supplier to the arts & crafts industry. The company has two locations with the main production center located in Ashville, North Carolina. Highwater Clays produces a wide range of clay bodies using fireclays, ball clays, kaolin, and stoneware clays. All the clay bodies consist of complex compositions and must be mixed into one reliable consistency.

Mixing Then Vs. Now

Lancaster Products K6 High Shear mixer is used in the production of clay bodies for the Arts & Crafts Industry.

To achieve this consistent mix, Highwater Clays relies on a Lancaster Products K6 high shear mixer. The company installed the K6 mixer over twenty years ago and, with successful business growth, needs to add another high shear mixer to keep up with demand. Highwater Clays’ Operations Manager, Jonathan St. Onge elaborates, “We use the mixer for clay mixing only, and the mixer runs all day every day. Very seldom do we have any problems or issues.”

He continues, “The Lancaster high shear mixer blends effortlessly and completely; it’s well made and well thought out in the design. Previously, we had the old paddle mixers, which created pockets of under saturated clay in the blending process. The entire clay mixture must be allowed to get wet and stay wet in the mixer. If not, this results in pockets of wet and dry areas in the mix. But with the Lancaster mixer, there are never voids or dry pockets in the mix.”

Saving Changeover Time

In addition to creating a better clay body mix, the production process improved exponentially when the previous mixers were replaced with the Lancaster K6 mixer. St. Onge explains, “We run color mixes starting with a bright white up to a dark red. At the end of each color process, we need to wash the machine to change it over. The Lancaster mixer is very easy to access for cleaning, due to the size of the doors. It takes about three hours to completely wash and clean the mixer and be ready to start again. The old paddle mixers would take two to three days to disassemble and clean! Our production with the Lancaster mixers has increased dramatically just from this process alone. Our operators are much happier now, even though washing the mixer isn’t much fun.”

Mixer Installation and Setup

Two decades ago, Highwater Clays removed the paddle mixing system and selected a Lancaster Products mixer as a replacement. The K6 High Shear mixer is a comprehensive system – Lancaster Products provides the equipment, setup, and operator training. St. Onge comments, “The environment in our facility can be extremely dusty at times. It is a ‘mud factory’ after all.  But while we mitigate dust with collection protocols, this can still affect the automation of our machinery.”  He adds, “With Lancaster’s help, we reconfigured the mixer to more of a blend of automation and manual operation. This approach worked very well and increased our production from the previous mixers. The Lancaster Mixers have completely satisfied the needs of our production and are very easy to clean and operate.”

Continued Support

Highwater Clays continues to grow and expand their production capabilities. The K6 mixer is slated for an overhaul and maintenance, and a new K6 mixer is coming on-line later in the year. “Lancaster Products has been great to work with.” St. Onge exclaims. “We had a situation where there was ’catastrophic operator error,’ and we needed help to get the mixer running again. The people as Lancaster Products were very understanding about the situation and jumped in to get the mixer fixed and keep our production moving.”

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.
