Magaldi Power SpA: A Profile


Magaldi, founded in 1929, is the world’s leading manufacturer of industrial machinery and plants for the transportation of materials in severe conditions, used in foundries, smelters, steel mills, cement plants, incinerator plants and solid-fuel power plants, with more than 1000 installations worldwide.

Our technologies are based on the Magaldi Superbelt® technology: a patented steel belt conveyor able to convey hot, abrasive and heavy materials in extreme conditions, from fines to bulk material.


Magaldi Superbelt®conveyor: a patented steel belt conveyor able to convey hot, abrasive and heavy materials in extreme conditions, from castings to foundry sand.

The main advantage of all Magaldi conveyors is the high dependability due to the construction features of the Magaldi Superbelt® belt: a multi-link traction media supported by upper idlers with plates directly attached to a steel mesh.

Compared to a traditional chain belt (single link), the mesh ensures that the conveyor will never stop. Even in the extremely unlikely event that part of the mesh fails, the mesh would continue to offer the correct traction force to enable the conveyor to operate. On the contrary, a failure on a traditional chain conveyor leads to the complete shutdown of the production line.

The Magaldi portfolio of solutions developed for the Foundry industry and widely applied in more than 20 Countries includes a large list of applications that represent the perfect compromise as they are neither based on a traditional Apron technology nor a common Vibrating one.

Magaldi Superbelt® “PR type”: designed to facilitate sorting and degating operations in foundries. Without sidewalls, it allows operators to drag the castings over the lateral chutes during the sorting operation. Thanks to the Superbelt® smooth and noiseless (below 68 dB) operation, the equipment can be used as a moving worktable. Chipping and de-gating of the castings can be safely carried out directly on the belt, without the need of lifting each single casting to place it on the lateral worktables or to sort in lateral boxes.

Magaldi Superbelt® “PZ type”: based on the features of the Superbelt “P type”, adding a belt surface without steps in the overlapping area of the pans.

It is the ideal solution for applications with robots or where the precise and repeatable position of the casting is required. In some applications, automatic sorting by a fix deviator is allowed.

Magaldi Superbelt® furnace feeding system: able to convey and feed heavy metallic scrap to furnace in a very tough environment. The system is fitted with a static reception hopper installed onto the Superbelt® charging section lined with anti-wear steel, an outlet chute specifically designed to fit the furnace hood while opened containing fumes and dust and to direct the scrap into the center of the furnace, reducing the furnace damages. The system can be mounted on a motorized trolley chassis to move forward and backward in order to enters the furnace, filling it in a very short time and improving worker safety.

Magaldi Superbelt® DRI: thanks to its ability to withstand high temperature, it ensures a dependable transportation of DRI in an insulated environment, allowing to minimize the loss of temperature inside the DRI.

The innovative sealing skirt-boarded applied in the carrying section of the Magaldi Superbelt® DRI conveyor allows to contain the inert gas in the conveying section, minimizing the re-oxidation of the DRI too. In this way, all the Fe contained in the DRI contributes to the production of the furnace, also minimizing the slag quantity.

Magaldi designs and supplies special conveyors for metal refining and metallurgical processes, allowing to maintain high temperature on an inert atmosphere or, alternatively, to enhance the cooling process during material transportation.
