Adopt “high tower spray” production device. The specific gravity of the product is 0.25～0.50gcm³. The product particles and components have good uniformity, good solubility and stable quality. The exhaust gas of the entire production system is discharged up to the standard, and there is no sewage discharge. The dry exhaust gas adopts a dry and wet combined dust removal system, which meets the environmental protection standards and saves energy and reduces consumption. A complete workshop dust removal system is set up, and the operating environment is clean and tidy. Advanced design technology and reasonable planning.
