The graphite raw material (needle coke or petroleum coke) is mixed with the binder and pulverized by air flow (crushing). According to the different products, graphite raw materials and adhesives (graphitized) are mixed in different proportions, the mixing ratio is 100: (5~20), the MATERIAL is transferred into the hopper through the vacuum feeder, and then the hopper is put into the air flow mill for removing iron PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC,
The raw materials with 5-10mm diameter are ground to 5-10 microns. Air flow grinding and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC after iron removal, the cyclone dust collector is used to collect the required particle size materials, the dust collection rate is about 80%, the tail gas is filtered by the filter element filter and discharged, the dust removal efficiency is greater than 99%. The filter element is made of filter cloth with pores smaller than 0.2 micron, which can intercept all dust above 0.2 micron. The fan controls the whole system in a negative pressure state.
Difference: pretreatment mill is divided into mechanical mill and air mill. Now the mainstream is air mill and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal parallel. There are many kinds of adhesives, usually petroleum asphalt, coal asphalt, phenolic resin or epoxy resin.
Pretreatment is not the key link. The main task is to get the precursor with the required size by screening, and to get various homogenous particles as far as possible to reduce the expansion coefficient.
