Since 1972 the Magaldi Superbelt has been used to handle hot, heavy, abrasive and sharp materials in the following applications:

Cement

Hot clinker transportation

Hot clinker weighing

Coal, limestone and slag extraction from hopper

Foundries

Castings, hot sands and burrs, risers and molds transportation

Castings cooling

Risers removal (also by manipulator)

Scraps pre-heating and furnaces charging

Cupola's slag dry removal

Sand extraction from hoppers

Steelworks

Hot sinter weighing

Briquettes handling and cooling

Dangerous fines handling (lead and zinc oxides)

Scraps handling

Forges

Hot forgings transportation (1260 °C)

Forgings transportation after shot blasting machines

Power Plants

Bottom ash dry handling and cooling

Bottom ash post-combustion directly under the boilers

In traditional apron conveyors a chain can break in its weakest point and maintenance is immediately required.
The Magaldi Superbelt is made up by the assembly of a high tensile steel fabric belt onto which a series of steel pans, partially overlapped, is fixed.
Even if one or more wires of the fabric breaks, it is not necessary to stop immediately the conveyor. The belt can keep on operating till the next planned stoppage of the plant.

As witnessed from the running installations, the belt has a life of more than 10 years.
This is demonstrated by the fact that the Magaldi Superbelt (e.g. the assembly of mesh and plates) comes with a 3 years guarantee.

Abrasive materials do not affect Magaldi Superbelt life because there is no relative movement between handled material and Superbelt pans during conveyance. Abrasive materials have no effect on the life of the Magaldi Superbelt.

The Magaldi Superbelt withstands higher temperatures than standard chain conveyors, because the belt components are free to expand in any direction without distortion. The take-up device automatically compensates for thermal expansions.
The mesh construction ensures very fast heat dissipation.

The Superbelt's pans fit so tightly that there is no clearance between adjacent pans. Constant tension through the tensioning device ensures a very high contact pressure in the overlapping area. As consequence no leakage of fines can occur.

Depending on the application:

Pneumatic

Pneumo-hydraulic

Counterweight

The most common is the pneumatic system, made by two pneumatic cilinders that push the tail trolley.
Big conveyors or feeders under big hoppers can require the pneumo-hydraulic or the counterweight system.

Magaldi Superbelt belt is completely supported by idlers across its entire width. These idlers can be closely spaced in impact areas so that stresses are distributed over a large area; the plates are not subjected to any bending moments and no deformation can occur.
Specific tests performed in Japan shows that the mesh belt has a fine characteristic to absorb impact loads.
Critical failure during special impact conditions could cause bending of rollers. These can be very easily replaced during scheduled maintenance periods because a few bent rollers do not affect the normal operation of the conveyor.

The design of the Magaldi Superbelt is very similar to traditional conveyors. It can be easy to fit the carrying idlers and return rollers on existing frames of rubber belts or apron conveyors, turning the old equipment into a very dependable conveyor.
Often it is also possible to reuse the head and tail drums, pillow blocks and bearings the drive.

The Magaldi Superbelt undergoes negligible wear and tear and unscheduled maintenance shutdowns are not required. Replacement of idlers is very easy and quick, just like in rubber belt conveyors.
It has no chains and no sprockets that are the critical components of traditional apron that need frequent maintenance.
The bearings of the idlers of the Superbelt are life lubricated; the bearings of the head and tail pulleys need lubrication only after 4000 hours of operation.
Anyway the easy maintenance can be performed during scheduled plant shutdowns.

Technically it is possible to replace an idler without stopping the conveyor, using adequate safety precautions.
Anyway an accidental failure of one or several idlers is not a critical event that compromise the operation of the conveyor.

This concept is related to the absolute dependability of the Magaldi Superbelt.

The steel wire fabric is over-designed and has a service factor of 20 - 50 times the breaking load (depending from the application).

A failure of one or several idlers do not compromise the operation of the conveyor

All the other components (motor, gearbox, bearings etc.) are "heavy duty" type designed to survive to the most catastophic event.

The diameter of the head and tail pulleys is very large compared to the overlap pitch of the pans. Consequently while passing over the drums, the pans open out only about few degrees. The side walls are constructed in such a way to ensure that they always overlap during this passage.

Technically, it is possible to run the belt in the reverse direction; anyway this must be done only under no load conditions or for a few seconds during accidental jamming. On load the belt must be run only in the designated direction, to prevent trapping of material between pans at tail section.

Yes, it is. Infact, any part of the belt can be changed very easily. The two transverse rods bordering the section to be changed, can be removed easily and the belt piece can be taken out. The new piece can be immediately installed using the same transverse rods.
On the contrary, it is not possible to replace few links in a chain of an apron conveyor, because of the change in the pitch of the chain links and of the sprocket teeth due to wear.
In this case the entire chain along with the head and tail sprockets have to be replaced.

The minimum width is 400 mm (16 in).
Regarding the maximum width there are running installations 2.000 mm (78 in) wide. It is possible to provide 2.400 mm (95 in) wide pans.

The Magaldi Superbelt "E" type, provided with vertical cleats, installed in SOCOCIM cement plant, is 54° inclined .
It is used for the transportation of 120 t/h of red hot clinker @ 650°C (1200°F).

The Magaldi Superbelt "P" type installed in Teksid Hua Dong foundry, is 107 meters long.
It is used for the trasportation of 8 t/h of sprues @ 650°C (1200°F).

It depends on the application. However to ensure the belt longevity, we do not recommend to operate at speeds greater than 0.3 m/s (60 ft/min).

All idlers, rollers, pulleys and bearings are standard type. Magaldi Industrie selects the heavy-duty ones with oversized shaft, shell, bearings etc.
The belt (mesh + pans) is the only special component as it is a patented by Magaldi Industrie.

One of the particular features of the Magaldi Superbelt conveyor is its very silent operation; noise level is below 65 dB like rubber conveyor belts.

The Magaldi Superbelt does not leak fines and does not shake, ensuring that no dust can contaminate environment.
Moreover there is a version of the Magaldi Superbelt that we call Ecomag that is completely enclosed in a dust-tight housing.

It depends on the application.
The pans, 5 or 8 mm tichness (1/5 in or 1/3 in) can be made of carbon steel, manganese steel or stainless steel; the mesh can be made of carbon steel or stainless steel.
