Lancaster High Shear Mixers are used extensively in the blending, mixing and granulation of powder metallurgy raw materials. Our mixers can be used to granulate the raw metal powders to ensure a homogeneous mixture.
The powders can also be granulated in the mixer to provide uniform mixtures and a more uniform flow into the press mold. This translation can be done under atmospheric conditions or even an inert gas blanket when required. The upper pan seal on the Lancaster Mixer allows the mixing pan to be purged with inert gas. Inert gas leakage is minimized by concentrically machined rings that make up the grease filled labyrinths seal arrangement.
This granulation process can improve the overall quality of thru parts pressed and also increase the density of the powder before pressing. This increased density prior to pressing results in a higher density and stronger part after pressing.
Recover the waste streams
The Lancaster High Shear Mixer can be used to recover the waste streams and dust from a steel mill. These waste streams can include floor sweeping, dust collected from the cupola and other general bag house dust collected throughout the process. These materials can then be combined and blended with a binding agent to allow reintroduction into the melting furnace.
The Lancaster High Shear Mixer can be used to blend and begin the graduation process for the production of iron ore pellets. Blending the iron ore with the bentonite prior to entering the standard balling drum will ensure a more homogeneous mixture, thus resulting in a reduction in the amount of bentonite required to create the iron ore pellets. A reduction in bentonite usage will result in a significant cost saving in the production of green iron ore pellets.
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.
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.
