In-Line Material Handling Fan

PROBLEM: Many paper, film, corrugated or metal processes generate more scrap than they can handle manually. In these applications a pneumatic scrap handling system is required to get scrap out of the production system without slowing manufacturing speed. However, if the nature of the scrap material is not taken into consideration, maintenance problems may add unexpected expense and compromise efficiency. 

SOLUTION:  Although in-line fan systems are the most basic pneumatic scrap handling systems, the need for custom solutions is strong. Some materials will quickly damage the fans used in these systems, and sometimes fans will damage the scrap making it worth less to recyclers. Abrasive materials will also quickly wear out critical points in the conveyance process.  

Consequently, Compass starts with a detailed look at the material being conveyed when we custom design any in-line fan system. Then we consider the peculiarities of the manufacturing process, the recycling potential and the requirements of scrap recyclers. All play a role in determining the correctly sized and configured system promising the longest service life with the lowest maintenance costs and quickest payback. Our extensive experience moving thousands of different materials provides a head start in determining the system best suited to your particular high-speed scrap handling needs.  

Plus

• Low energy costs, especially when compared to Venturi-based systems.
• Scalable: Works efficiently over long conveyance distance using fans in series.
• Works efficiently with larger diameter conveyance ducts.
• Reduced airflow to separator / dust collector.

Minus

• Cannot be used to convey large materials or ribbons of material without using in-line cutters between pick-up point and fan.
• Noise levels can be problematic.  Silencers can be used.
• Fan blades can wear down when handling abrasive or corrosive materials.
• Increased dust generation can be created in conveyance.
