Wet ultrafine grinding and high-speed crusher processing of fly ash slurry


Power plants and coal mines generate fly ash filter cakes with high moisture content; wet‑process pulping often leaves coarse particles, and direct use as a filler yields low added value. Conventional crushing merely achieves basic size reduction, resulting in insufficient powder uniformity and stratification during slurry settling, which hinders the implementation of solid‑waste resource‑recovery projects.

The wet‑process ultrafine cell mill and high‑speed crusher features an optimized chamber for fly ash slurries, using a high‑speed turbine to break down coarse particles and employing multi‑stage circulating grinding to refine the powder, thereby enhancing slurry suspension stability and improving the performance of finished building‑material and chemical filler products. Its vertical, integrated body combines grinding, circulation, and cooling functions, requiring fewer auxiliary devices.

The equipment features an optimized noise‑reduction design, ensuring that plant‑site noise levels comply with industry standards. Its processing capacity is well suited to small and medium‑sized processing plants and solid‑waste treatment facilities in mining areas. The system operates under a sealed negative‑pressure environment, eliminating dust emissions, and is equipped with an automated material‑feeding and discharging system to minimize manual handling, thereby supporting the resource‑efficient utilization of fly ash.
