PRODUCT

 

The First 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 .Then the chip form is moved to the main Mill Machine which is programmed to produce required particle size. At our modern laboratory, particle sizes are checked by Mastersizer Malvern 300E and whiteness is measured with Konica minolta by Quality control engineers. The analysis schedule is every 30 minutes until the whole processing is completed and analysis results are recorded at factory.
