We are actively practicing the concept of circular economy, turning the "waste" in the production process into utilizable resources. Slotting dust recycling system integrates dust collection, purification and resource utilization. It utilizes a high-power fan to generate negative pressure to accurately adsorb the dust, and adopts the double high-efficiency filtration technology of "cyclone separation + cloth bag", with a purification efficiency as high as 99.5% to ensure clean air emissions. This technology not only guarantees the cleanliness of the production environment and the health and safety of employees, but also significantly reduces the generation of solid waste, realizes the internal recycling of production waste, effectively saves primary resources and reduces the environmental load.
