[0031] Take 100kg of graphite corner waste, first cut it into small pieces with scissors, and use the 30B all-purpose pulverizer produced by Jiangyin Tianfeng Pharmaceutical Machinery Co., Ltd. for primary pulverization, and the pulverized particles are less than 3mm; In the steam vortex pulverizer produced by Lianfeng Pulverizing Machinery Co., Ltd., the main classifier is 10HZ, the upper classifier is 99HZ, and the fan is 33HZ for fine processing, until the median diameter D50 of the material is less than 45μm; the third is to mix the above powder with the binder 30 kg of asphalt powder and 200 kg of worm graphite with specifications of 80 meshes were added to the horizontal ribbon mixer produced by Shanghai Shuanglong Group and mixed for 3.5 hours, then added to the feeding bin of the flexible graphite production line imported from Japan by Yichang Xincheng Graphite Co., Ltd. Repeated calendering and heat treatment at 1100°C in the air-isolated state, and then rolling again ...
