The trip to the 13th Industrial Solid‑Waste Exchange Conference in Shuozhou, Shanxi has been successfully completed. Centered on technology‑driven development and energy transition, the conference brought together solid‑waste practitioners and experts from research institutes across the country. Participants conducted in‑depth discussions on coal‑based solid‑waste treatment and green energy transition, exploring new pathways for solid‑waste resource utilization.Qingdao Shina, with years of expertise in powder equipment manufacturing, took part in this industry event. Supported by our in‑house physical factory with full‑fledged production, commissioning and material‑testing systems, the company has long focused on powder‑based resource utilization of industrial solid waste. Tailored complete sets of crushing and classifying solutions have been developed for typical northern solid‑waste materials such as fly ash, coal gangue and desulfurized gypsum, to tackle practical production challenges in fine grinding and classification of solid waste.
