Belt conveyor Magaldi

for the metallurgical industrysilofeeder

The production of high-quality sinter is crucial for assuring stable blast furnace productivity with low consumption of reductants. Sinter quality begins with the proper selection and mixing of the raw materials (iron ore fines, limestone, return fines, slag-forming elements, and coke fines). Since the inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption, proper dosing of the sinter feed composition is mandatory. The Magaldi Weigh Belt Feeders allow for optimizing recipes, minimizing waste, and increasing productivity. Installed under the hopper of each storage silo, they are used to extract, continuously weigh and feed the mixing drum, where raw materials are humidified, homogenized, and granulated before sintering. Thanks to the use of the Superbelt® conveyor technology, they offer superior resistance to shocks, high temperatures, and abrasion. The Superbelt® conveyor is easily transformed into a weigh feeder through load cells installed on the supporting structure of the carrying idlers. The actual feed rate is determined by combining the belt speed, monitored by an encoder, and the weight signal, given by the load cells. The controller automatically adjusts the belt speed to maintain the actual feed rate close to the set point value.
