What is a diaphragm valve?
In order to convey material, a solenoid valve (above centre) creates a connection via a hose to the conveying vacuum. This sucks in the diaphragm and opens the valve closure (in green). …

What is to be taken into account with regard to the material discharge?
mo describes various concepts of the material discharge flaps
One task of the material supply is to convey material to the hopper loader on the processing machine. …

How is the plastic granulate separated from the conveying air?
By increasing the line diameter of the material line (d1) to the internal diameter of the hopper loader (d2), the air speed (red arrows) decreases, while the air volume (yellow arrows) remains the same
mo reveals the secret of the “suspended plastic granule”
In the broadest sense, operation of a hopper loader can be compared with a vacuum cleaner – but with one significant difference: …

What is a permanent central vacuum?
Example for a permanent central vacuum, installed in motan-colortronic’s new Tech Center in Friedrichsdorf: in the centre two central filters, left two side channel blowers on top of each other
mo explains the characteristics and advantages of a permanent central vacuum
For large productions with numerous material loaders and consequently many delivery points, large throughputs, frequent conveying cycles, and long conveying distances, there are two solutions for automated material supply: …
37
How can abrasion be minimized for vacuum conveying systems?
mo explains abrasion and measures to prevent abrasion
The distances the material travels in the pipe lines from the material supply to the processing machines can be gruelling – both for the material as well as the material lines. …
32
When is it necessary to purge material lines?
When conveying powder, filter and powder must be suited to each other, otherwise particles may permeate the filter or block the filtermo
mo explains why purging can contribute to plant safety
The point of purging is to remove or minimise transported material deposits from a material line. …
31
How does the dedusting of granulate work?
mo explains the dedusting units and implosion purging of filters
For the production of high quality parts, fine dedusting of the material may be required at the end of the conveying process, even if the material is virgin material. …
29
Which marginal conditions are important when choosing a material loader?
From the left: Material loader with side mounted vacuum valve and angled material inlet, material loader with membrane vacuum valve for clean room use, dedusting module, material inlet flap with reinforced deflector
mo explains details regarding the configuration of material loaders
In addition to the throughput and the local conditions, numerous other criteria are important for the conception of a material supply, which can also affect the configuration of material loaders. …
27
How does the material reach the processing machine?
Different versions of stand-alone material loaders for vacuum conveying: Venturi material loader METRO VL (lower left) and METRO HES 50 (middle) for throughputs of up to 50 kg/h back and right material loaders of the METRO HBS range to be connected to a separate blower station. …
