plateshaped clay minerals showed higher Blaine numbers. Moreover, when the feed of the magnetic separator was grinded, the reduction in the grain size increased the Blaine number. In the Chadormalu plant, a retention time of minutes in the mill was associated with the highest Blaine number as well as the least recovery of phosphorous minerals.

As a result, the green pellet generated presented higher concentration of pellets between 10 and 16 mm (%1016 mm), with a higher drop number than typically observed when produced with ballmilled feedstock. Consequently, on the induration process, a higher pellet deformation was observed during the pot grate loading.

Abstract. INALUM has been using high Sulphur and low Sulphur coke with 60:40 ratios since 2004. Furthermore, some efforts have been done to increase anode quality, such as Blaine Number Stabilization, Butt Cleaning Improvement, and Cone Crusher Utilization. By controlling the fine fractions output in green paste mixing, the Blaine number ...

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

Cold compressive strength (CCS) and apparent porosity (AP) of pellets are essential properties regarding the burden of blast furnaces. The optimal required values for industries are KN CCS and 21% AP. Blaine fineness and firing temperature are the decisive parameters analyzed here. During firing, microstructure phases such as silicate, hematite, and pore are formed. The phase's grain ...
