STEEL BELT CONVEYORS FOR SEVERE CONDITIONS since 1929

MA’ADEN - Industrial Mineral Company

THE CHALLENGE

For its Magnesite plant, Ma’aden - the largest mining company in Saudi Arabia - was looking at the replacement of a rubber belt weighing feeder that was suffering from the material high temperature (380° C) and abrasiveness.

 

THE CUSTOMER

Ma’aden is a diversified mining company, active in gold base metals mining with five mines and over 11 million ounces of JORC compliant gold resources at operational and exploration sites.
Ma’aden was formed by Royal decree in 1997 to facilitate the development of Saudi Arabia’s mineral resources. The Saudi Government still owns 50% of its shares while the remaining 50% are listed in the Saudi Stock Exchange.
The Company has developed its activities beyond gold mine exploitation thanks to the agreement with US aluminium giant Alcoa to build an aluminium complex including a refinery and a smelter.
Currently, Ma’aden is working to further broaden the Company’s mineral portfolio.

 

 

THE SOLUTION

The Customer need for replacing the existing rubber belt weighing feeder was satisfied by installing a Magaldi Weighing Feeder: an assembly of the dependable Magaldi Superbelt® steel belt conveyor and a weighing system made by four loading cells that continuously weigh the layer of the conveyed material.
The speed of the Magaldi Weighing Feeder is controlled through a frequency converter. The feed rate is determined by integrating the belt speed, taken from a tachometer, and the weight signal, given by the load cells.
The controller compares the actual feed rate with the desired one and it adjusts the belt speed in order to provide a uniform and controlled feed rate.

Magaldi realized  the complete supply and erection of the weighing feeder, integrating the electrical signals coming from the weighing in the existing PLC control system.

The Magaldi Weighing Feeder is characterised by:

Offering tailored solutions to meet Customers technical needs, Magaldi asserts itself as reliable partner in the most challenging projects.
