Description

Technical Field

[0001] The utility model belongs to the field of industrial production equipment, and specifically relates to a hedging crushing bin. Background Art

[0002] Powdered materials are the main raw materials for lithium battery processing. Powdered raw materials for lithium battery processing are composed of metal elements such as lithium, cobalt, nickel and various inorganic compounds. The proportion and quality of these elements and compounds have a great influence on the performance and life of lithium batteries. Usually, lithium cobalt oxide is used in the positive electrode of lithium batteries, while carbon materials are used in the negative electrode. The main sources of lithium battery powder raw materials are lithium, cobalt, nickel and other metal elements extracted from minerals. Lithium can be extracted from lithium ores such as spodumene, malachite and tremolite. Cobalt and nickel can be extracted from minerals such as chalcopyrite and chlorite. Because the abundance of metal elements such as lithium, cobalt and nickel is not high, their extraction process usually requires a series of chemical reactions and physical treatments. Crushing operation is a necessary step in the processing of lithium battery processing raw materials.

[0003] The counter-jet pulverizer adds the material into the pulverizing chamber from the outside, and four pairs of opposing nozzles accelerate the coarse particles, which impact each other in the pulverizing chamber and are pulverized. After the materials are classified by inertia for the first time and by a cyclone separator for the second time (see figure), the particle size of the output material is adjusted by changing the size of the roller tube and the airflow. In the prior art, the counter-jet pulverizer has been improved to adapt to different usage scenarios.

[0004] Patent No. CN201810824185.6 discloses a counter-attack airflow heating and drying crushing device, including a crushing mechanism and a dry airflow blowing mechanism; the crushing mechanism includes a grading part, a cavity connecting part and a material conveying part. The present invention is provided with an air filter to make the air entering the crushing mechanism clean; the heat exchanger increases the temperature and prolongs the storage time. This setting corresponds to materials with high cleanliness requirements and can avoid air pollution. However, for materials with high requirements for crushing particle size, only one crushing and grading is required, and the crushing requirements cannot be met. Utility Model Content
