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.


Inspection: Inspection of the working tools at regular intervals based on hours of use is also critical.  Tools should be inspected for wear and repaired or replaced when indicated.  Placement of mixing tools in the machine should also be verified to prevent unnecessary wear and maximize machine performance.


Safety: Of course, all lock out, tag out and safety procedures should always be followed when inspecting your mixer.  Following manufacturer guidelines for procedures and frequency of maintenance for your specific mixer are recommended.

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.

Mix-Granulating with a Lancaster K-Series High Shear Mixer

Many reasons compel industrial operations to enlarge solid particles for handling. Some objectives may be: enhancing flow properties, recycling, de-dusting, densifying, freezing ingredient distribution, improving mold filling properties, etc. Size–Enlargement in the powder technology context include: agglomerating, pelletizing, granulating and briquetting. This article deals with particle enlargement generally through a snowballing mechanism, with some shear action, but without the application of high pressure or extrusion.

Most powders having the ability to fuse, or slightly dissolve in the presence of a liquid, can be granulated quite easily. Others may be coaxed to form granules by the introduction of some suitable binders. The binders may act as a medium for the solid particles to adhere to each other by modifying interfacial activities. Some may form a matrix to capture the particles. Others may involve chemical reactions to achieve the objective.
