Granulate conveying
METRO HES/MES

The METRO HES/MES single phase loader range enables processors to automate a key area of the production process cost effectively, bringing significant benefits of improved efficiency and process management.
Plastic granulate is conveyed quickly and cleanly to a processing machine hopper, a drying bin or a day bin. Material is delivered exactly when needed, keeping machines running and avoiding costly downtime. Material wastage is eliminated and the workspace is kept clean and safe. They can handle throughputs from 5 up to 250 kg/h.

Noise insulated motors Quiet in operation

Noise insulation is fitted to the METRO HES/MES 50 and 250 material loaders making them quiet in operation.

Brushless motors Less maintenance through brushless motors.

The METRO HES/MES 250 models are equipped with reliable brushless motors and soft-start for wear-free operation.

Hinged lid Easy to clean.

All METRO HES/MES models have a hinged lid for easy cleaning.

Filter cleaning Guarantees constant and stable material conveying and reduces maintenance costs.

The cloth filter is automatically cleaned by compressed air after each loading. This guarantees constant and reliable material conveying and reduces maintenance costs for the loader. Because the material loader is air-tight, the conveying performance remains stable and there is no dust around the unit.

Dampened discharge flap Prevents material jamming and vacuum loss.

A spring loaded damper on the discharge flap prevents the flap from completely closing when not under vacuum. During pneumatic conveying, any granules left lying on the discharge flap which might get trapped are first sucked away. With increasing vacuum, the flap is then pressed against the spring and will close completely.

Stainless steel discharge flap Abrasion resistant.

Because the large material outlet has a discharge flap which is made of stainless steel, it is abrasion resistant and meets all requirements for medical or food packaging applications. The angled design increases the outlet area and helps with materials which may bridge.

Discharge flap counterweight Visual status of the loading cycle and great for service.

The counterweight of the discharge flap is mounted on the outside of the loader discharge module. This means that the actual status of the loading cycle is visible at all times. Service work can be easily and quickly carried out, because of easy accessibility.

METRO MES machine loader version Perfect for hygroscopic materials and where space is limited.

When conveying hygroscopic materials with small throughputs or where space is limited a machine loader version is available. The discharge module of the loader has no discharge flap and the unit must be mounted directly on the feed throat of the processing machine.
Your benefit is that no machine supply hopper is required and very little material is stored at the machine. This is especially important for dried materials as the holding time of the material is kept to an absolute minimum.

Electro-polished stainless steel Contamination free and easy to clean.

All material loaders are modular and are constructed from electro-polished stainless steel, guaranteeing you contamination-free operation and easy clean down due to the high quality surface finish.

Proportioning of two materials Integrated into the control so saving you money.

The control for a METROMIX proportioning valve is already integrated into the METRO HES loader control. You can easily adjust the percentage and number of material layers per conveying cycle using the keypad.

METROMIX proportioning valve Accurate and reliable addition and mixing of regrind and virgin materials.

The electro-polished stainless steel METROMIX proportioning valve can be connected to a METRO HES material loader using the plug socket located on the side of the control. A large transparent access panel gives you easy access for cleaning.

Line purging Ensuring correctly conditioned material is delivered to the machine.

Integrated line purging function in the METRO HES control. When connected with a motan purging suction box the material feedline can be cleared of any material after every conveying cycle. This is essential for the conveying of hygroscopic materials and for fast and trouble-free material changes.

Control Versatile and easy to use.

Easily operated control:

  • The conveying time can easily be changed on the plastic film keypad
  • 7-segment LED display for set value/actual value display
  • Illuminated symbols for status display
  • Programme selection for METROMIX – purge function or periodic emptying of the granulator suction box
  • Alarm suppressed at initial filling
  • Automatic loader switch-off and error display for motor protection after 50 false conveys
