Material Handling Systems MHS

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.

6 Continuous run valve Double-MM Vacuum Power Unit SB Ring Blowers Vakuum power units VE Vakuum Pumps A big variety of vacuum pumps are available. Please use the MHS data sheet to collect all necessary data for sizing the pump and the other components of the system SB ring blower with control panel

7 RN-Series Vacuum Reciever Pellet Screen (quick in/out) Flapper or Swing Gate Vacuum Connection Material Inlet Proximity Switch Electric Connection Box

8 RN-Series Vacuum Reciever Special solution for regrind or other materials that intend to build bridges: Steep wall hopper Mechanical bridge breaker

9 Sequenzing Panels Different versions of sequenzing panels are available. Anyway it is very easy for the operator to activate/deactivate the individual stations. PCC-control panel “Vacu-Bloc”

10 RDJ Dust Collector RDJ dust collector as a central unit to minimize labour costs for manual filter exchange and downtimes of the line cost saving for non recyclable filters at pump inlet Self cleaning by inversion of air flow

11 Compact Material Handling System 2) Compact MHS with RX recievers and PCC-control panel “VacuBloc” a cost-effective alternative

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

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

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 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)
