A Method for Inhibiting the Formation of Large Pellets Applicable to Disc Pelletizer

Abstract

The invention discloses a method for inhibiting the generation of large pellets and suitable for being used in a disk pelletizer. The unqualified large pellets are crushed by equipment for inhibiting the generation of the large pellets and arranged adjacent to a pelletizer disk by adjusting the position of an inhibiting rod device of the equipment for inhibiting the generation of the large pellets according to the actual positions of the unqualified large pellets generated in the pelletizer disk, blocking the inhibiting rod device on the lower half part of the pelletizer disk and the positions opposite to those of the unqualified large pellets and driving the unqualified large pellets to impact onto the inhibiting rod device through the rotary pelletizer disk. According to the method, the unqualified large pellets are crushed according to the actual positions of the unqualified large pellets generated in the pelletizer disk. The method is high in crushing efficiency and safety and strong in practicability.

Description

technical field [0001] The invention relates to a method for suppressing the formation of large pellets, in particular to a method for suppressing the formation of large pellets suitable for a disc pelletizer, and belongs to the technical field of iron ore powder pelletization. Background technique [0002] The disc pelletizer is used for pelletizing iron ore powder, and it is one of the main supporting equipment for various pelletizing plants. After mixing coke powder, limestone powder (or quicklime) and iron concentrate powder in the mixer, they are input to the feeding device on the upper part of the disc pelletizer, and the feeding device is evenly fed to the pelletizer, and at the same time The mist spray water is supplied by the sprinkler device. The disc of the pelletizing machine arranged obliquely is rotated by mechanical transmission. The mixture and spraying water are rolled into balls in the disc of the pelletizing machine. The shaft sieve is used for sieving, ...

AI Technical Summary

Problems solved by technology

[0006] (1) The actual position of the unqualified large pellets in the disc of the pelletizing machine is not fixed. Sometimes the unqualified large pellets may appear in a position in the disc, and sometimes the unqualified large pellets The pellets appear in another position of the disc. When crushing, according to the actual production situation, the crushing area should be set at the position where the unqualified large pellets appear for crushing, so as to achieve the best crushing efficiency, and the above patents The crushing device is fixedly installed above the disc. When crushing, the crushing area is fixed. In this way, the crushing device in the above patent cannot flexibly adjust its crushing area according to the actual production situation, so as to achieve best crushing efficiency;
