Pilot Size Mikro Pulverizer

 

Invented in 1923, the Mikro Pulverizer® Hammer and Screen Mill is a high-speed mechanical impact mill designed for continuous size reduction of a wide range of materials down to D90 < 45 μm. This video describes the features and operation of the pilot scale (No. 1) Mikro Pulverizer which runs at 5 hp.

Feed material is added to the hopper and conveyed to a single screw and transported into the grinding chamber. A multiple deflecting liner on the cover redirects material into the paths of stirrup swinging hammers. On the bottom half of the grinding chamber, a perforated screen determines the size of the material that releases from the chamber. Material that exits the grinding chamber goes into a discharge hopper. To relieve air produced by the mill, an air relieve mechanism can be attached.

The mill has higher legs to allow easy access to different discharge hoppers. A VFD panel controls the speeds of the mill and feeder and gives amperage on both rotors.

Design and Options:

  • Laboratory (1 HP) to production (200 HP) available
  • Process 250 gram batches up to 15 tons/hr
  • Easy to operate and maintain
  • Available in mild steel, stainless steel, and with wear protection
  • Pressure shock resistant (PSR) models available
  • Various configurations available to produce a wide range of products and results
  • Compact and easy to clean design
  • Suitable for chemical, pharmaceutical, food, mineral, and cosmetic applications
  • Cryogenic grinding possible

Controlled Particle Size
Optimum particle size reduction can greatly affect chemical reaction speeds, solubility, weight, color, volume, appearance and strength of ground products. Mikro-Pulverizers® provide accuracy in particle size control because the grinding action is entirely mechanical. Once a mill is set to deliver a certain product, it will continue to produce exactly the same result without adjustment.

Grind, Blend, and Disperse
Mikro Pulverizers® grind, blend, and disperse in a single operation. Intensive action thoroughly mixes dissimilar ingredients into a finished product. Heat-sensitive materials are handled by adjustment of mill speed, hammers, screen and discharge air relief, as well as with pneumatic conveying. Conditioned air may be bled into a grinding chamber, or the feed may be pre-conditioned or chilled.

The Mikro Pulverizer® has evolved into the preeminent industrial mill with thousands of worldwide installations.
