Will there be dust in the sintering process of lithium cobalt oxide materials?

Is there any dust during the sintering process of lithium cobalt oxide? The materials and products processed by lithium batteries are all solid powders. With the continuous development of operations, the contradiction between open processing and reducing dust pollution and protecting the health of workers must be dealt with unpreventably. In order to change the current situation of excessive dust in operating positions and improve the processing environment, exploratory dust monitoring was carried out in the processing workshop from April 2017 to February 2018. The dust concentration in the sintering part of the rotary kiln was tested and evaluated. According to the 'Occupational Hygiene Testing StandardsThe on-site dust concentration test shows that the sample detection function meets the multiple requirements of the national occupational health exposure limit value pc-twa exceeding the standard. Small replenishment site lithium cobalt oxide dust concentration sample. The Akfc-92g single-dust sampler is used for on-site detection, the filter membrane enrichment method is used for sampling, and the laboratory weighing method is used for analysis. The sampling point, sampling number, instrument and method are the same before and after processing. Effect: The currently processed lithium cobalt oxide rotary kilns all adopt fully automatic processing methods, and the dust concentration application meets the requirements of the country's operational health exceeding the limit. The precipitation and dispersion of materials during the sintering process of the lithium cobalt oxide rotary kiln is an important reason for the small amount of dust in the workshop. The data of cobalt tetroxide and lithium oxide are supplied by the screw feeder independently developed by the company. Lithium cobalt oxide is sintered and produced into powder. Both the inlet and outlet of the lithium cobalt oxide rotary kiln have dynamic sealing devices, and only a small amount of secondary dust appears during the operation of the technicians. The lithium cobalt oxide rotary kiln equipment independently developed by Phoenix Valley Energy Saving Technology Co., Ltd. selects a dynamic sealing system, which can completely isolate the material, ensure the quality of the sintered material, ensure the collection of the fully enclosed structure during the sintering process, and strictly control the sintering atmosphere of the material. Meet the requirements of environmental protection and deal with difficulties in atmosphere control. It has important uses in preventing dust leakage, improving the working environment of workers, enhancing the company's image and economic benefits, and being more conducive to the company's long-term development. Jointly strengthen the publicity and education of dust prevention knowledge for workers; post-feeding, dumping, and receiving staff should strengthen a single protection, such as wearing a dust mask that meets national health standards is still very necessary; perfecting occupational health files Establish a regular inspection system for dust working environment and a regular health inspection system for dust working personnel with employee health files to prevent the occurrence of occupational diseases.
