White marble lumps is classified and selected at the quarry to ensure whiteness and purity. The lumps are transported to factory and cleaned by high pressure water then moved to Jaw Crusher to produce chip form.   

The chip form is moved to the Ultra- Fine Mill which is programmed to produce required particle size. The fine powder is blown to classifier system to reject particles which does not meet the standard sizes. At our laboratory, engineers always keep control of product quality by using modern equipment such as Malvern Mastersizer 3000E and Chorma meter Konica Minolta CR-410. The analysis schedule is every 30 minutes until the whole processing is completed and analysis results are recorded at factory.
