The Immersion mill was invented and patented by Hockmeyer in the 1990s to replace the outmoded horizontal milling technologies and three roll mills that process the feedstock very slowly through the shear zone, are cumbersome to disassemble and clean, are labor-intensive, and are fairly inefficient by modern-day standards. In immersion milling, the feedstock is circulated through a powerful and turbulent shear zone at very high velocity, as fast as 50 passes per hour. This produces very narrow particle size distributions, decreases the bead-to-product ratio necessary for efficient milling, and dramatically increases productivity and throughput. Over the years, Hockmeyer has continued to improve on the original design by adding more impact points, flow boosters, high-viscosity model (HCPS), and nano-milling features.
The Hockmeyer HCP Immersion Mill utilizes rapid recirculation milling technology to achieve a smaller particle size and tighter particle distribution and is faster than any other technology in the marketplace. This is achieved by pumping the slurry through the media field many more times and more efficiently than any other mill, including basket, horizontal or vertical mills. Circulation can be as fast as 50 passes per hour.
Rapid mixing and milling of raw materials are completed in one tank engaged for the entire cycle. The machine is designed for use in multiple tanks with various capacities.
