Hosokawa Mikro UMP - Introduction

The Hosokawa Mikro® UMP Universal Milling System is a compact, high-speed impact mill that provides coarse granulation or fine size reduction with interchangeable rotor configurations. The UMP is a next-generation product which builds on the Mikro Pulverizer® Hammer and Screen Mill by providing the same grind as the classic hammer and screen setup while adding the flexibility of converting to a pin mill for fine size reduction or a rigid rotor for de-agglomeration. The unit is designed for milling soft to medium-hard materials down to D97 = 35 µm with laboratory scale models to full production systems.

Targeted applications are food and pharma

The Mikro® UMP Universal Milling System utilizes the same design and operating principles perfected in the original Mikro Pulverizer® Hammer and Screen Mill. It was developed to meet the increased demand for high-performance machines for multiple applications. An interchangeable grinding mechanism for flexible particle size distribution is a key feature. Multiple feed and collection options further enhance the flexibility of the Mikro® UMP across food, pharmaceutical, and chemical applications.

The video offers an introduction and a quick look at some of the UMP’s design features. The fabricated grinding chamber is constructed in 316 stainless steel with a high-quality 0.6 micron Ra finish. Higher quality finishes are available for specialty applications. The access door is hinged to the grinding chamber and is secured with a tri-clamp connection for easy and quick inspection and cleaning. The bearing housing is a cantilevered design and includes maintenance-free, sealed-for-life bearings. There are double-lip seals and a gas purge between the drive and process areas to eliminate material contamination and premature wear to drive components.
The Mikro UMP is a cleanly designed mill with limited internal surfaces which facilitate easy cleaning. Two other grinding elements – the pin and knife rotors- can be easily installed. Lab and production models are available from 1 HP to 40 HP and capacity ranges from five grams/batch up to 3,000 lb/hr.
