Description

TECHNICAL FIELD

[0001] The utility model relates to lithium ore processing field for lithium phosphate iron production, specifically, a kind of lithium phosphate iron production lithium ore crushing device. BACKGROUND

[0002] The main raw material of lithium phosphate iron battery is lithium ore, and the lithium ore needs to be crushed first during processing. The crushed lithium ore is then subjected to roasting and screening to facilitate the extraction of lithium in the later stage.

[0003] After searching, it was found that the application number CN202321247237.0, named a feeding device for ore processing production line, proposed that due to the different particle sizes of lithium ore, some large lithium ore was more difficult to heat internally during high-temperature roasting, resulting in high roasting efficiency. The lithium ore was crushed by the crushing roller shaft, and the crushed lithium ore fell onto the screen of the screening mechanism. The screen was displaced left and right under the combined action of the spring and the crescent-shaped protrusion on the rotating wheel, and the ore was screened. The screened lithium ore fell through the screen holes and exited the discharge port into the roasting furnace for high-temperature roasting. The lithium ore that did not pass the screening slid down the screen into the chute. The screw in the reflux mechanism rotated under the drive of the motor and displaced the lithium ore upward, and eventually slid into the crushing roller shaft above for secondary crushing, ensuring that the lithium ore entering the roasting furnace had the appropriate particle size and improving production efficiency. However, in actual use, the screen width is much greater than the feeding port width of the screw, causing a large amount of lithium ore to accumulate on both sides of the screw feeding rod, which easily causes blockage, making the lifting and recycling unstable and unreliable. If blockage occurs, the screw rotation is affected, the crescent-shaped protrusion cannot rotate, the screen cannot move back and forth for screening, the entire screening work is suspended, the accumulation of lithium ore is further aggravated, and the blockage phenomenon is further aggravated. Further improvements can be made.
