Hot sinter conveying belt most use in Sinter plants agglomerate iron ore fine particles (dust), with other fine materials at high temperatures, to create a product that can be used in a blast furnace. The final product, so called “sinter”, is then used to convert iron into steel. The sinter is a small, irregular nodule of iron mixed with small amounts of other minerals. The sintering process fuses the constituent materials to make a single porous mass with little change in the chemical properties of the ingredients. At the sinter machine exit, the material is broken into smaller pieces by a breaker and is cooled down using a forced air stream. At the sinter cooler discharge, temperatures are still high, ranging 400 to 700 °C, so that the hot sinter can be transported only by a conveyor which can withstand very high temperatures. Moreover, the sinter is a very abrasive material, acting as a micro-tool over the time that abrades the surfaces on which it is sliding. This type of sinter is also toxic and needs to be transported by a dust-tight conveyor to prevent fine particles from contaminating the environment and exposing the plant operators to safety hazards.

For this high-value product, reliability is the main feature required of any equipment designed to operate in sinter plants. In fact, a forced outage might prove to be extremely costly in terms of production losses and hence profit losses. The HR belt is therefore the ideal conveyor for handling hot sinter, ensuring reliable, safe and environmental friendly operations. The Hot sinter conveying belt key component is the Monster Belting “E type”, designed completely enclosed in a steel casing, suitable for preventing dust dispersion to the environment. A simple mechanical self-cleaning device removes the fine residuals from the bottom of the casing. The HR200C belt can be equipped with the which is a chain conveyor enclosed in an independent casing, tailored around the HR250C belt tail section. Its function is to receive the fine residuals, retreived from the high temperautre conveyor belt bottom by the self-cleaning device, and to reload them onto the Superbelt
