1. Material Handling Systems MHS

2. 2 Material Handling Systems (MHS) Material handling systems are an important part of an extrusion line. Their job is to transport the raw material from point A to point B. “A chain is only as strong as ist weakest link“. That means, that if the transport system doesn‘t work properly, the extrusion line is unable to deliver the requested quality. PROCESS CONTROL material handling systems are calculated by a simulation software. In this way we ensure to provide our customers with an economic and reliable solution.

16. 16 Material Handling Systems (MHS) 3)RSD – Self Loading Vacuum Reciever

17. 17 RSD – Self Loading Vacuum Reciever  Conveying rate 350 kg/h at 3 m vertical and 3 m horizontal.  Pressure cleaning of security screen.  Maintenance-free; brushless, 3 stage turbine 1,1 kW  Noise level 72 dB(A) according to DIN 45635  Separation of particles from conveying air by cyclone principle  Stop of conveying cycle by proximity switch  Integrated control with alert (horn + light)  Option: Sight-glass

18. 18 RSD – Self Loading Vacuum Reciever RSD can be mounted either on a GUARDIAN ® -blender or an X-Series blender

19. 19 Calculation Sheet The same system, but 4 instead of 3 elbows => VE03 pump not sufficient Pipe work with 3 elbows 90° => VE03 pump O.K.

20. 20 It is necessary to know the number of elbows and the length of the tube system as detailed as possible because of their influence on the pressure loss and therefore the sioze of the vacuum pump. 1 elbow = approx. 15 m of straight tube Basics for calculation (friction in tubes) Straight tube: only a few particles hit the inner wall of the tube Elbow: Nearly all particles hit the inner wall of the tube. They are decelerated and have to be accelerated again, which results in a significant pressure loss (and in consequence a loss of energy)
