METRO P

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 material inlet and outlet sizes which can be accurately adapted to suit the throughputs and conveying distances you require.

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.

To cope with different material conveying throughputs, hopper loaders are available in 10, 25, or 50 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 taken into account. 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.

The METRO PB versions come in a variety of loader and blower sizes for material throughputs of up to 1000 kg/h. Included in the scope of supply is a floor-mounted blower station comprising of a control and a maintenance-free, low-noise three-phase blower. The easy-to-use colour graphic display with touch panel is located at a convenient height allowing you to easily operate the stand-alone system.

The METRO PCN and PBN models are designed for non-free-flowing and free-flowing powders. A large diameter pneumatic butterfly valve (Ø300mm) is used for all non-free- flowing powders, guaranteeing safe material discharge. The opening and closing of the valve helps to break any bridged material.

All METRO PC 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.

Up to 7 generously dimensioned PTFE-coated star cartridge filters can be installed in the loader. The large filter area to air flow ratio and the Teflon membrane coating on the filters provides you with optimum separation for all powders.

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. Depending on the material to be conveyed, the filter cleaning sequences can be optimised in the setup menu of the control.

The optional fluidisation aid installed in the hopper body of the N-type loaders eliminates bridging and guarantees safe discharge even with non-free-flowing powders.

A rotary paddle switch can be optionally installed to automatically stop the conveying cycle when the level is reached.

When conveying non-free-flowing powders there is the option of a screw discharge module in a collecting hopper fitted with a horizontal agitator. The integrated feed-screw conveys the powder directly into the material feed line. By varying the feed-screw speed, the amount of material being conveyed can be adjusted.

Several different levels of automation are available for controlling the METRO PC loaders. The loaders are fully compatible with other motan products and can be networked in motan’s CONTROLnet world. Both powder and granulate material loaders can be integrated into the same conveying system.
