Weighing The Pros And Cons Of Horizontal, Vertical, And Brush-Type Dedusters

By Andre Petric, President, Kraemer USA

There are a number of things to consider when integrating a deduster into your manufacturing line. Before contacting a supplier, be sure to assess your needs by gathering the following four pieces of data:

  1. Identify your minimum and maximum tablet sizes. The size of the tablets, along with the speed at which tablets enter the deduster, determines the volume needed on the helix to effectively transport and dedust.
  2. Know the maximum speed related to running all sizes of tablets.  This information allows the provider to determine the deduster capacity, so the appropriate machine size can be recommended.
  3. Determine if you need a metal detector along with the deduster. A metal detector uses roughly 10” of vertical height, which must be accounted for in the machine height calculation.
  4. Assess the press outlet height and collection container inlet height. You can figure this by measuring the vertical distance from the floor to the table outlet chute at the press, and the tablet collection container height. These two dimensions will allow you to calculate the deduster conveying height — the vertical height needed to properly reach the collection container.
