Universal, flexible milling systems allow operators to rapidly change rotor configurations to produce different materials or for frequently cleanings. Hosokawa’s Mikro® UMP Universal Milling Systems is a high speed impact mill designed to grind a wide range of materials for coarse granulation to ultra-fine powders. Mikro UMP mills have similar performance to Hosokawa’s Mikro Pulverizer Hammer & Screen Mill but with the added value of four rotor options: pin disks, hammer & screen, knives and attrition disks.
The Mikro® UMP Universal Milling System utilizes the same design and operating principles perfected in the original Mikro Pulverizer® Hammer & Screen Mill. The Mikro® UMP was developed to meet the increased market demand for high performance machines for multiple applications. An interchangeable grinding mechanism for flexible particle size distribution is a key feature to this machine’s design. Multiple feed and collection options further enhance the flexibility of the Mikro® UMP Universal Milling System across food, pharmaceutical and chemical applications.
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.
A pin disc assembly includes a stationary pin rotor disc mounted to the inside door cover and a rotating pin disc mounted to the main drive shaft of the mill. The pins interlace creating a labyrinth for materials to pass through when rotating. The rotors have a one piece pressed pin design to provide for ease of cleaning.
This rotor produces the tightest particle size distribution of the Mikro® UMP grinding options. Material is pulverized by mechanical impact until the material is fine enough to discharge through the retaining screen. There are a variety of retaining screens and deflector liners available to produce the required size reduction and desired particle size distribution.
A fixed blade rigid rotor uses a cutting or impact force (depending on the orientation of the rotor) to reduce materials to coarse or granular powders. This option is well suited for large materials when a wider and coarse particle size distribution is necessary.
Hosokawa’s attrition plates are uniquely engineered to finely grind heat sensitive materials without cooling gas or liquid nitrogen. The serrated teeth of the rotating and stator plates create shear forces that cut materials into fine powders with a narrow particle size distribution.
