Metallurgy | Powder
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.

Our last post focused on our experience in concept testing and how it applies to our high shear mixer sample testing process. This post will dig in a little deeper and provide insight into the breadth of data we provide to our customers when they commission Lancaster Products to provide sample testing for them.
Over the past 30 years, we have collaborated with our customers to perform proof of concept testing in our K1 laboratory mixers for thousands of materials samples. The desired outcome of the testing is customer dependent but typical requirements are along the lines of pelletizing/granulating to specific size ranges and desired yields, mixing to achieve homogenization, or reduced reaction times of existing processes. Outcomes provided are 1) proof of concept in achieving the desired product, and/or 2) optimization of the current mix processes. Our engineers perform the tests in our controlled laboratory, log all key information in our database, and share all data with our customers for future reference. Below is a list that summarizes some of the information we collect during every test run we perform:read more
