Description

Technical Field

[0001] The utility model relates to the technical field of iron ore oxidation pellet equipment, in particular to a crushing device. Background Art

[0002] At present, there are three main types of roasting equipment for pelletizing ore: vertical furnace, belt roasting machine, chain grate machine-rotary kiln-ring cooler. However, no matter which production method is adopted, the pelletizing process is indispensable. The materials prepared in the previous process are transported to the pelletizing workshop, and then the materials are evenly and continuously dropped onto the pelletizing plate. The green balls are sent to the roller screen by the conveyor belt through the pelletizing plate. The unqualified large-particle green balls and small-particle green balls are screened and returned to the pelletizing workshop for re-pelletizing. Especially in the cold winter season in the north or in cold areas with low temperature, the returned materials are low in temperature, and the green balls contain a certain amount of water, which causes the water to solidify and freeze, increasing the strength of the returned materials and making them difficult to break naturally. The green balls continue to grow larger, resulting in an increase in the return rate and a reduction in the qualified rate of pelletizing.

[0003] In view of the above technical problems, the utility model designs a crushing device, which has simple structure, convenient installation, manufacture and use, stable equipment operation, convenient maintenance and flexible operation, which greatly reduces the return of ore and improves the qualified rate of ball making.
