New Jet Mill for New Energy Positive and Negative Electrode Materials for Lithium Batteries

Product Description

Product Description DCF series jet mill is a fluid bed jet mill which features opposed grinding nozzles and a dynamic classifier. Air or inert gas at elevated pressure is injected through specially designed nozzles directly into the grinding chamber of the mill, creating a sonic or supersonic grinding stream. Raw feed is automatically introduced to the mill chamber by an interlocked feed control system.
The agitation provided by the grinding chamber and nozzle design cause particles to become entrained in the air or inert gas stream. Particle size reduction is accomplished by high velocity collisions between particles. Small particles are then swept towards the classifier which rotates at high speed above the grinding. The speed of the classifier is preset for the proper sized product and is electronically controlled. Material which is fluidized fine enough to overcome the inertial force generated by the classifier escapes the jet mill and is collected as product. Oversized particles are recycled by the classifier back into the grinding chamber for further reduction.
With the advanced design of the integrated, dynamic classifier, particle size distribution can be more easily controlled. Efficient use of compressed air and total system automation ensure manufactured product is of the highest quality. Capable of grinding dry powders to 0.5~45 micron averages with specific top size and/or bottom size requirements.
The air jet mill has become a conventional choice in battery materials, crushing and grading equipment at the end of the process, the performance of the final product has a great impact, so the processing of electrode materials is an important link, crushed products are unqualified or crushed, the yield will be greatly reduced, the loss is very large, therefore, the crushing equipment can produce products to achieve narrow particle size, no crushing and large particles, the requirements of low fine powder rate are particularly important.
According to the physical characteristics of the positive and negative electrode materials of the battery powder, different equipment is used to crush and classify to achieve the best output ratio. According to a large number of successful cases between our company and many battery powder enterprises, for lithium batteries and nickel-metal hydride battery specific materials, fluidized bed air flow pulverizer can be used to crush and classify. High purity requirements, anti-oxidation can use inert gas protection crushing classifier to isolate oxygen closed production.
Features • The preparation of many battery materials needs to be crushed and dried, there will be originally fine particles due to drying and agglomeration, or due to static electricity agglomeration, resulting in the size of raw materials is too large to be applied, air jet mill can also be applied to the depolymerization of battery materials, so it is widely used in this field.
• Classifier wheel arranged horizontally in the classifier top section.
• Laboratory up to Production Models.
• Cool and contamination-free grinding.
• Rapid cleaning and easy validation.
• low production loss.
• Top sizes as fine as D90 of 1 micron.
• Low noise (less than 75 dB).
• Variable speed classifier wheel for precise classification.
• Feature a Ceramic, PU lining to different materials.
• Be used to grind heat-sensitive products with critical heat limitations.
• Suitable for Chemicals, Minerals, Pharmaceuticals & Food Products.
Applications Battery powder positive and negative electrode materials: typical materials are lithium manganate, lithium cobalt oxide, lithium iron phosphate, lithium carbonate, spherical graphite, petroleum coke, asphalt coke, ternary materials, nickel metal hydride alloy, ferrous oxalate, lithium titanate, lithium manganate, lithium nickel manganate, etc.
