Dealing with Breaker Plate Contamination

Continuous-belt screen changers are an economical and efficient method of filtering out contaminants in thermoplastic material due to their ability to provide constant melt extrusion pressure to downstream processes over long periods of time. The absence of process interruptions needed to change screen packs in other types of filtration translates into increased production and decreased scrap, bringing maximum efficiency to your extrusion operation. However, if you notice that the pressure drop in your continuous belt screen changer is gradually increasing over time, despite regularly advancing the screen at recommended intervals, you may have a flow restriction from the gradual buildup of contaminants on breaker plate surfaces.

Development of Safety Standards for Film and Sheet Winding Machinery

As a manufacturer of machinery for the plastics industry, one of our main concerns when designing, engineering, and building these machines is to always keep safety in mind. Operating machinery can always carry the risk of injury. Workers can be struck by moving parts, trapped between rollers, belts, and pulleys, and cut or punctured by sharp edges. That’s why safety standardization efforts are developed to define, for example, the type of guarding, fencing, or torque limitation.
