Criteria for selecting dryers for use in the minerals, chemicals and recycling industries
Summary: In sometimes fierce competition, the various dryer suppliers promote the technology of their particular dryer range. This has led to uncertainty among users with regard to selecting the right or optimal drying system. One common dilemma is the decision for or against the use of drum dryers (rotary kiln dryers) or fluidized bed dryers (vibration fluidized bed dryers).
