Our CaCO3 powder is produced by the most advanced automatic production technology in the world nowaday, with super fine powder grinding system with casting disk technology, Classifier 800TTD (single driver, twin turbo-discharge allow classifying products with particle sizes D97 from 3 to 45 microns and control system is programmed by specialized software.
Thoroughly selected at the mine for each target industries. Then it was rechecked when passing through the weighing station, gathering at the warehouse, and cleaning to avoid impurities. Our CaCO3 powder is tested and controlled strictly by the staff of KCS who are well trained, skilled, experienced and seasoned, working in a scientific environment with full page experimental equipment and modern scale in the country today.
The ultra-fine calcium carbonate powder is a key in Sun Materials’s commitment to our customers. Our company is always taking the samples daily for quality testing in the laboratory with full equipment modern in accordance with international standards: particle size laser analyzer with MALVERN 3000E of England, MINOTA CR-410. Particularly for each shipment, before being delivered to customers, our CaCO3 powder is re-examined to ensure that the customers of the stone powder delivery to meet the requirements of customers.
Moreover, our products undergo 7 strict quality control steps, bringing trust to customers:
Step1: We classify stone resources for each target industry, paint industry, plastic industry…

Step3: Quality controllers check materials on vehicles before materials are weighted on alectronic scales for moving to the warehouse yard.
Step4: Stones are peeled off cover, washed and classified by color.
Step5: Stones before taken into the jaw grinding line are approved under the supervision of the director in charge of product quality.
Step6: Product quality inspection department has teams of engineers with many years of experience in quality control of stone powder (CaCO3 powder), high responsibility. They monitor and control continuously and strictly quality of products at frequency of every 30 minutes under support of the most advanced devices.
+ Malvern Mastersizer machine 3000E for measuring particle sizes.
+ Konica Minolta CR410 for meansuring whiteness.
Detecting of unsatisfactory products. Product quality inspection department will call operation room to make adjustment timely. And the products are on process that time shall be classified at the lower grade.
Step7: Product quality control staffs are responsible for coordinating with storekeepers check products quality the last time to arrange and stow goods in warehouse into lots numbered in order to control them exactly.
