Chip form
Raw limestone is selected and sorted out from the assembly area in quarry under close supervising of the factory Quality and Inspection Staff (QIS), and then transported to the factory’s material Yard. In this area, the QIS repeats selecting and sorting out process to ensure the most qualified input material. The material is then fed into bunker via a vibration feeder. After the limestone is crushed into an average size of 10-40 mm, it will be moved into the vibrating screens for sorting out the most suitable size. The vibrating screens are installed in layers with various hole dimentions to sort out the product sizes as required by particular customers.
