The “heart” of lithium battery production contains combustible dust such as graphite and electrode materials. While these materials provide the energy to the battery, they also pose significant safety risks. When the dust mixes with air and reaches the explosive limit, even a small amount of static electricity or a spark can trigger serious consequences. How do we define safety red lines and keep risks within safe limits? Dust explosion-proof zones (zones 20, 21, and 22) are internationally recognized safety standards. A compliant and professional explosion-proof dust collector is the final guardian of this red line.<\/p>\n\n\n\n Dust explosion prevention zones assign clear risk labels to different areas based on the frequency and concentration of dust. This is the starting point for all safety protection measures.<\/p>\n\n\n\n Zone 20 (High-Risk Zone): <\/strong>Areas where combustible dust clouds are continuously or persistently present during normal operation.<\/p>\n\n\n\n \u25b6 Typical Scenarios: <\/strong>Inside grinding mills, inside powder silos.<\/p>\n\n\n\n Zone 21 (Medium-Risk Zone):<\/strong> Areas where combustible dust clouds may occasionally appear during normal operation.<\/p>\n\n\n\n \u25b6 Typical Scenarios: <\/strong>Near feeding ports, conveyor pipe interfaces, and dust collector unloading points.<\/p>\n\n\n\n Zone 22 (Low-Risk Zone):<\/strong> Areas where dust clouds are unlikely to appear during normal operation, and may only exist briefly under abnormal circumstances.<\/p>\n\n\n\n \u25b6 Typical Scenarios:<\/strong> Corners of the workshop far from dust sources, and the external perimeter of equipment.<\/p>\n\n\n\n Moland<\/strong>\u2019<\/strong>s View:<\/strong> Regardless of the risk level, as long as combustible dust is present, explosion-proof equipment with the corresponding protection level must be installed in accordance with safety standards such as <GB 15577>. This is not only a mandatory compliance requirement but also the bottom line of responsibility for safe production by enterprises.<\/p>\n\n\n\n
