Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical pellets, in particular to a bulk material processing device for metallurgical pellets. Background Art

[0002] The pelletizing plants currently producing pellets in my country use the chain grate-rotary kiln process. There are two types of return materials in this process. One is the return of raw balls; this type of return material is not roasted, and it will be broken by stirring in the mixer, which has no effect on pelletizing. The second is the return material in the return section of the chain grate head; this part of the return material has a great impact on pelletizing. There are two types of this part of the return material: the ash in the ash box of the chain grate and the balls leaking from the head of the chain grate. The particle size of the ash is very fine and does not affect pelletizing. The balls leaking from the shovel plate at the head of the chain grate are brought to the ash conveying belt through the flipped grate plate and enter the mixer. The balls here have a certain strength after being roasted by the chain grate and are not easy to break. After entering the pelletizing machine, they are rolled into large balls, and they are screened out when the raw balls are screened, and then enter the pelletizing machine again after the return material. This kind of balls accumulate more and more in the pelletizing machine, which will eventually affect the efficiency of the pelletizing machine. The unqualified balls produced by the pelletizing machine are more than the finished balls (qualified balls are 9mm to 16mm), which seriously affects the production of the pelletizing plant;

[0003] The announcement number CN 209873047 U discloses a bulk material processing device for metallurgical pellet ore, including a feed hopper cover, a feed hopper, a cone crushing seat, a collecting box, a driving motor and an eccentric crushing roller, a shock-absorbing seat is arranged at the bottom of the collecting box, a crushing cavity is arranged inside the cone crushing seat, an eccentric crushing roller is arranged in the middle of the crushing cavity, and a cooling box is arranged outside the cone crushing seat located at the crushing cavity;

[0004] There may be two problems when using it. First, after the device crushes the ore, the ore of different sizes is collected uniformly by the staff, so that the staff need to manually screen it after the collection is completed, so as to collect and classify the screened ore, which makes the work efficiency low; second, after the classification is completed, the staff need to add the frame material that has not passed the screening to the inside of the feeding device, which makes the staff more time-consuming and labor-intensive. Therefore, we propose a bulk material processing device for metallurgical pellet ore. Utility Model Content
