This in turn is composed of individual machines such as screens, mixing drums, ignition furnace ...
There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.

The belt-type sintering machine is driven by the head and tail wheels to move the trolley equipped with the sintering mixture. The bottom material and raw materials are added to the head and ignited. Within the effective sintering length, the mixture is burned from top to bottom to form a hot sinter . In the sintering process, it also has the ...
The process of sintering is an agglomeration technique for fine ore that relies on heat to melt the surface of smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter strand at the heart of the plant. The simplified process sequence is as follows:
Basic sintering technology. The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant.
Feeder – A feeder machine is included in a feeder crushing plant, a type of mobile or permanent crushing plant, to control the flow of raw materials into the primary crusher. The feeder's main function is to regulate and maintain a steady supply of material for the crushing process, ensuring that the crusher operates effectively and ...
The sintering plant process comprises several key components. First, we have the raw material handling component, which stores and discharges the materials transferred from the material yard. Second, the sinter machine that produces the actual sinter ore. The third part is the crushing facility that crushes and screens the iron ore …
In steel manufacturing, the sintering process is the main emission source of PCDD/Fs followed by the electric arc furnace process (Zhu et al. 2016). Studies performed on iron ore sintering plants have indicated that PCDD/Fs are formed through a de novo synthesis, taking place in the sinter bed in regions where the temperature is 250–450 °C.
