Sintering refers to the process of transforming powdered materials into a dense solid; it is a traditional manufacturing technique. People have long utilized this process to produce ceramics, powder metallurgy products, refractory materials, and ultra-high-temperature materials. In metallurgical processes, sintering typically denotes the procedure in which various powdered iron-bearing raw materials, mixed with an appropriate amount of fuel and flux and combined with water, undergo a series of physicochemical changes on sintering equipment after mixing and pelletizing, ultimately forming sintered lumps. In industrial production, belt-type draft sintering machines are widely employed for producing sintered ore. The main steps include preparing the sinter mix, batching and blending, sintering, and product handling.
The sintering machine is suitable for sintering operations at large-scale ferrous metallurgy sintering plants, particularly well-suited for medium- and large-sized sintering facilities processing iron ore fines.
It serves as the primary equipment in the draft sintering process, enabling the sintering of fine and rich ore powders with varying compositions and particle sizes into solid lumps while partially removing harmful impurities such as sulfur and phosphorus from the ore. Sintering machines are available in several specifications, categorized by sintering area and differing in length and width; users select models based on their production capacity or site conditions. Larger sintering areas correspond to higher production capacities.
