METRO G/F/R

With the METRO G/F/R material loaders, large quantities of granulate, dusty regrind and flakes can be conveyed automatically to the hopper of a processing machine, drying bin or day bin. Filters with sophisticated cleaning technology and large outlet flaps guarantee trouble-free operation. Via the hinged lid, free from vacuum and material hoses, the loaders can be quickly and easily cleaned during material changes.

METRO G/F/R system loaders Large material throughputs, full flexibility and a reduction in materials handling costs.

To cope with large material conveying throughputs of up to 6000kg/h. Hopper loaders are available in 60, 100, or 150 litre sizes. The system loaders are an integral part of a centralised material conveying system. Each system is designed to suit your specific needs; e.g. throughput, material types, and plant layout are individually considered. In addition to different loader sizes, a wide variety of conveying options, controls, blowers, and filter techniques allow the creation of the optimum system for your facility. By centralising your conveying system, the cost of material handling is reduced considerably.

METRO G/F/R: Modular design
METRO G/F/R: Modular design
Modular design No product redundancy - as your production requirements change so does the material loader.

All material loaders are fully modular and can be matched to different throughputs and requirements depending on the application. Not only are there different material loader volumes but also different filter options and material inlet / outlet sizes which can be accurately adapted to suit throughputs and conveying distances.

METRO G/F/R: Electro-polished stainless steel
Electro-polished stainless steel Contamination free and easy to clean.

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

METRO G/F/R: Material discharge valve
Material discharge valve Large diameter butterfly valve for optimum discharge of flake and regrind materials.

The METRO G/F/R models are designed for conveying of granulate, flake and regrind materials.

A large diameter pneumatic butterfly valve (Ø300mm) is used, guaranteeing safe material discharge. The opening and closing of the valve helps to break any bridged material.

METRO G/F/R: Optional dust removal
Optional dust removal Active dust removal during material discharge

As material is discharged from the METRO G/F/R material loader, dust is actively removed and conveyed to the central dust filter. This is achieved by generating an air flow using the central vacuum pump.

METRO G/F/R: Vacuum valve
METRO G/F/R: Vacuum valve
Vacuum valve Multiple loaders can be connected to one blower.

All METRO G/F/R loaders are fitted with a vacuum valve. The valve opens the vacuum line when material is being conveyed and closes with an airtight seal after the conveying phase. This allows multiple loaders to be connected to one blower.

METRO G/F/R: METRO G/F - Vacuum valve with implosion
METRO G/F - Vacuum valve with implosion Guarantees constant and stable material conveying and reduces maintenance costs.

The reliable vacuum valve is suitable for light as well as higher pressures and offers with its powerful pneumatic cylinder the ideal solution for almost all uses. Silicone-free seals or a variant for high temperatures are possible. For clean room applications, the filter can be retrofitted without an adapter and with minimum effort.

In addition to implosion cleaning the mesh filter can also be automatically cleaned by compressed air after each loading cycle.

METRO R – Special filter unit Guarantees constant and stable material conveying and reduces maintenance costs

A large PTFE-coated cloth filter is installed in the loader. The large filter area to air flow ratio and the Teflon membrane coating on the filter provides you with optimum dust separation.

A compressed air accumulator integrated in the hinged lid of the hopper loader with direct connection of the air outlet nozzles secures high-efficient filter cleaning.

METRO G/F/R: Material request sensor
Material request sensor Process security – dust resistant.

A rotary paddle switch is installed below the discharge valve to automatically start the conveying cycle when the material level falls below the sensor.

METRO G/F/R: Max level sensor in every hopper loader
Max level sensor in every hopper loader Process security – no over or under filling of the loader.

A rotary paddle switch is installed in the loader body to automatically stop the conveying cycle when the max. level is reached.

METRO G/F/R: Loader control box
Loader control box Versatile and easy to use.

All METRO G/F/R loaders are equipped with the C box: our most advanced control box with alarm and status indication, on/off and other functions located directly at the loader.
