Ultra-micro gas flow grinding is to overcome the internal cohesive force of the solids in the internal cohesion of the solids by mechanical or fluid power, thereby pulping 3 mm or more of the material particles to 10-25 microns. It was a high-tech of a material processing that was generated by the development of modern high-tech after the 1970s.
The three-dimensional positive material usually has basically two kinds, one is a lithium nickel-cobalt-aluminate NCA, a lithium nickel-cobalt-oxanate NCM, and their main use is used in three yuan. In the positive electrode material battery, a positive material is supplied to the battery. In three aspects, the main steps are in three aspects, and the first is: mixed abrasive, the second is: high temperature sintering, the third is: pulverization decomposition, which can make the original material particles to be ground, It is used to achieve a suitable particle size requirement, and then screened by a grading, which can be graded by the purchase of the hierarchical device-airflow pulverizer to obtain the ideal particles we need the particle size of the particles. The ideal particles are usually around 42 μm, up and down Floating can not exceed 6 μm, which is suitable for processing of ternary materials. The use MQW gas flow pulverizer can completely reach the machining requirements of the ternary material.
The MQW type gas flow pulverizer is used to process the three-dimensional positive electrode material advantage in the performance of:
Ø has plasticity, and the granular morphology is controlled, and the particle size is controlled. It is excellent in finished particle shape and can be used for shaping of different material properties and requirements. Ø The distribution of the material is narrow, and the finished product has a high density.
Ø The flour is low, the finished product is more than 96%.
Ø The internal liner is abrasion resistant, the equipment is small, and the purity of the finished product is high.
Ø Adopt frequency converter accurate control, material fineness can be adjusted at 0.5-100 Um.
Ø Full negative pressure operation, low noise, no dust pollution.
Trimed material uses the MQW type gas flow pulverizer to high-intensity turbine classification system, which can accurately separate the designated particle size after crushing, and the whole machine uses closed-circuit operation to effectively prevent dust pollution. In numerous three-yuan material processing enterprises, most users have chosen to use MQW airflow pulverizer to process, via user feedback, high precision of MQW airflow, strong anti-pollution, and stable equipment performance.
In terms of quality inspection, ALPA powder technology is particularly stricter. It is well known that a manufacturing process of a ultrafine powder is often up to hundreds. As a special equipment, the airflow pulverizer is like a special process, and it is possible to make a big disaster. Therefore, ALPA powder technology has established seven process stop points in the production process, which is strictly controlled by different engineers, and each other is independent and mutual supervision, and it is timely discovery and solve the problem. Any detail is unqualified, it is unable to enter the proceeding process, which is the quality monitoring of AlPa powder technology to the production process.
