A powder coating producer in Linyi, Shandong, upgraded its grinding stage with the Jatchen ACM40 air classifying mill. The unit grinds tableted powder coating into fine, uniform powder with a tight particle size distribution, and its stable daily operation has lifted plant output and product consistency.
Customer Background
The customer manufactures powder coatings and grinds extruded, cooled sheet into finished powder before packaging. Its previous grinding step could not hold a consistent particle size, which led to batch-to-batch variation and made it harder to meet the quality requirements of its downstream customers.
The Challenge
In powder coating production, the particle size distribution (D50 and D90) directly affects spraying performance, film smoothness, and shelf life. The plant needed a grinding mill system that could crush tableted material and classify the powder in a single pass, hold a fine and repeatable particle size, and run continuously with low dust and low wear.
The Jatchen Solution
Jatchen supplied the ACM40 grinding mill, an air classifying mill that combines crushing and classification in one unit. High-speed impellers break the tableted powder coating through impact and shearing, while the built-in air classifier separates the powder to the target size. The ACM40 is matched with the Jatchen classifier cyclone, which fine-tunes the fine fraction below 10 microns for a high-quality, consistent powder coating output.
Results and Benefits
Since the ACM40 went into service, grinding has run stably and precisely, giving the Linyi plant a tighter particle size distribution and less off-spec powder. Output increased, the grinding area is cleaner and lower-dust, and the improved consistency has strengthened company competitiveness with downstream customers.
