Problems solved by technology

[0003] However, the current method generally used by factories is to import the lithium iron phosphate precursor material into a sand mill, add a zirconium ball for sand milling, and after a few hours, export the material for subsequent processing after the test particle size reaches the required level. The process has the following disadvantages: 1. The efficiency is relatively low and the time is relatively long; 2: It is difficult to achieve the required particle size; 3: The particle size step range is large, and the particle size is uneven

Abstract

The invention provides a sanding device and method using zirconium balls in different sizes, and belongs to the field of sanding equipment. The sanding device comprises a stirrer, a first sanding machine, a second sanding machine and a third sanding machine which are sequentially communicated; a material conveyor is arranged between the stirrer and the first sanding machine, a material conveyor is arranged between the first sanding machine and the second sanding machine, and a material conveyor is arranged between the second sanding machine and the third sanding machine; and a plurality of big zirconium balls are arranged in the first sanding machine, a plurality of medium zirconium balls are arranged in the second sanding machine, and small zirconium balls are arranged in the third sanding machine. The sanding method includes the following steps that firstly, materials are injected into a stirring barrel to be evenly stirred; then the evenly-stirred materials are conveyed to the first sanding machine through the corresponding material conveyor for sanding; then the materials sanded through the first sanding machine are conveyed to the second sanding machine through the corresponding material conveyor for sanding; and finally the materials sanded through the second sanding machine are conveyed to the third sanding machine through the corresponding material conveyor for sanding.

Description

technical field [0001] The invention relates to the technical field of sand milling, in particular to a sand milling device and method using zirconium balls of different sizes. Background technique [0002] At present, in the process of preparing lithium-ion battery materials, especially nanoscale lithium iron phosphate cathode materials, in order to obtain high-quality and uniform lithium iron phosphate cathode materials more quickly, it is often necessary to sand-grind the lithium iron phosphate precursor in order to achieve Nanoscale of lithium iron phosphate material. [0003] However, the current method generally used by factories is to import the lithium iron phosphate precursor material into a sand mill, add a zirconium ball for sand milling, and after a few hours, export the material for subsequent processing after the test particle size reaches the required level. The process has the following disadvantages: 1. The efficiency is relatively low and the time is relat...
