Hosokawa Micron Powder Systems recently introduced the Universal Mikro® Pulverizer (UMP). From the inventors of the original high speed pulverizer comes a new line of pharmaceutical impact mills that provide the next level of performance and versatility to the Industry. This new line of mills offers the latest milling technology, coupled with a new ergonomic design and easy clean features. Now one mill can provide finished materials ranging from coarse granulations to ultra-fine particle size distributions. The results come from the unique capability to inter-change a variety of internal grinding elements coupled with a rotor tip speed that can be varied from 40 m/s to 160 m/s. The result is an extremely flexible machine to process a wide range of API’s and excipients. There are three model sizes available to handle capacities for a few kg/hr to several hundred kg/hr. The new series consists of models UPM-B, UPM-1 and UPM-2. Hosokawa offers these mill systems in a number of configurations that meet specific application requirements, including closed loop inert processing, 150 psi high pressure systems and high containment options to provide nanogram level containment and operator protection.

The UMP has been designed to replace the Bantam as a versatile size reduction apparatus with different configurations and model sizes available. Since the introduction just over a year ago, 20 units have been delivered with extremely positive feedback. 

The UMP features a fabricated housing with a hinged door and tri-clamp closure mechanism. It features interchangeable grinding mechanisms giving the end user unlimited ability to change particle size and distribution. The unit can be fitted with a knife type rotor to provide granular products. Mikro impact hammer and screen assembly can be substituted to make finer materials down of 50 microns. The pin discs and a new bearing housing design can run at a top speed of 28,000 rpm to produce products down to the 25 microns.
