This case study demonstrates how Lancaster Products mixers can effectively homogenize powders of differing densities into a uniform mixture, while increasing the overall mixture density in the absence of added moisture.

In typical ceramic processing applications, mixing / milling is performed using processes such as ball milling, which is a lengthy and energy-intensive process, often requiring processing times as long as 12 – 24 hours.
Could you achieve similar mixing in far less time?

Is this a new invention? Most technical books on mixing equipment rarely include this mixer design. Yet, counter-current rotating pan mixers have been serving industrial mixing needs for over half a century. So, how is this mixer different from, and perhaps superior to, other mixer designs?

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.

For batch processes, one can manipulate intensity by adding / removing mixing tools, or one can increase the speed of the mixing tool, or both. The speed approach generally follows the relationship that intensity varies as the square of the tool speed.

Variable Mixing Intensity with Lancaster K-Series Mixer can input custom-designed levels of mixing intensities, varying at will through the use of VFD control. The intensity range typically covers one order of magnitude, or roughly 1-10, to as much as 1-100. This wide range of intensity is more than adequate to handle any refractory applications for very short cycle times.

With a Lancaster K-series high shear mixer, it is possible to adjust mixing tool speed, moisture level and time to control granule size, the degree of granule consolidation, producing optimum granule densities and hardness. Within limits, drier, smaller and less dense granules are preferred because they economize energy usage, and residence time in downstream processing.
