Background
China is a big country for producing steel and iron, and sinter is the main raw material for making iron. Sintering is the process of mixing various powdered iron-containing materials with proper amount of fuel and flux, adding proper amount of water, mixing and pelletizing, and making the materials produce a series of physical and chemical changes in the sintering equipment to bond the mineral powder grains into blocks. In the sintering process, in order to ensure the quality of the sintered ore, the moisture of the sintering raw material must be strictly controlled, so the sintering raw material generally needs to be subjected to primary mixing and secondary mixing processes.

The purpose of secondary mixing is to continuously mix, pelletize and pelletize a small amount of water to improve the air permeability of the sintering raw material layer and meet the moisture requirement of the sintering raw material. And (4) after secondary mixing, conveying the sintering raw materials to a mixing bin of a sintering machine through a finished product adhesive tape machine and a transfer station. The ideal moisture value of the sintering raw material (mixture) is 7%, wherein the moisture rate of the primary mixing is controlled to be 6.8%, the adjustment range of the secondary mixing is 0.5%, and the fluctuation range of the moisture is ensured to be 7 +/-0.3%. At present, for the water adding control of a mixing system in a sintering process, most of water adding amount is determined by adopting artificial experience factors, and in addition, the control and the regulation of water are realized by adopting the monitoring and the feedback of a water content meter.
