Which equipment of lithium iron phosphate will use compressed air

In the production process of lithium iron phosphate, spray dryer, jet mill, mixing equipment, packaging equipment and pneumatic conveying system such equipment will use compressed air, its role covers drying, crushing, mixing, packaging and material transportation and other links. The following is the introduction of specific equipment and its role:

1. spray dryer: In the preparation process of lithium iron phosphate, the spray dryer is used to dry the stirred rubber into a uniform powder material. After the compressed air is filtered and heated in the spray dryer, it enters the air distributor at the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The feed liquid is sprayed into very fine mist beads by a high-speed centrifugal atomizer, which is in parallel contact with hot air and dried into a finished product in a very short time. The compressed air plays the role of carrying and dispersing the feed liquid here.
2. jet mill: The jet mill is used to crush the sintered lithium iron phosphate material. Compressed air is accelerated into supersonic air flow by Laval nozzle and then injected into the crushing zone, so that the material is fluidized and accelerated. In the comminution zone, the accelerated particles are comminuted against each other at the intersection of the nozzles. The crushed material is transported to the classification area by the rising air flow, and the fine powder meeting the particle size requirement is screened by the horizontally arranged classification channel. Compressed air here plays a role in accelerating and conveying materials.
3. Mixing equipment: In the preparation process of lithium iron phosphate, the mixing equipment is used to mix the materials of different components evenly. Although the mixing equipment itself does not directly use compressed air, in some automated mixing equipment, compressed air may be used to drive components such as pneumatic valves or pneumatic stirrers to achieve mixing and stirring of materials.
4. Packaging equipment in the packaging process of lithium iron phosphate, compressed air may be used to drive the pneumatic parts of the packaging machine, such as pneumatic clamps, pneumatic valves, etc., to realize the operations of grabbing, handling and packaging of packaging materials.
5. pneumatic conveying system: In the production process of lithium iron phosphate, the pneumatic conveying system is used to transport materials from one process link to another. Compressed air is used as the power source of pneumatic conveying, and the material is transported to the designated position through the pipeline. This conveying method has the advantages of high conveying efficiency, small footprint, and no dust pollution.
