Replacing the screen on a Hammer Mill


The Mikro Pulverizer Hammer and Screen Mill is an efficient mechanical mill designed for refinement and size reduction. It is capable of processing a range of materials, from chemicals like ammonium sulfate to food items like cinnamon and black pepper, and is capable of reducing the size of these materials to as little as 50 microns.

Changing the Screen Assembly

However, the Mikro Pulverizer Hammer and Screen Mill will not work efficiently if the machine is not maintained. This includes, but is not limited to, maintenance of the screen assembly. The screen assembly determines the resulting particle size of the materials that are being refined. If the screen is faulty, then it may result in a material size that is not desired. If a change in particle size is observed, then be sure to replace the screen assembly, as an improper particle size may result in large amounts of wasted material.

The video on the left shows the proper instructions for removing and replacing a screen assembly. Be sure to follow all necessary safety precautions, such as proper eye, ear and skin protection, along with all lock-out tag-out procedures.

Important notes on screen replacement:

  1. Ensure screen groove is clean before replacing screen.
  2. Be sure to hold the screen cam in-place while tightening the locking nut. Not doing so may result in a screen failure.
  3. The first bolts to be installed and tightened should be the two horizontal bolts that will pull the housing cover into the feed trough, which will keep the holding plate in its proper location. Failure to do so may result in the hammers hitting the holding plate.
