Production process
The raw materials are transported from the material storage area to the crushing workshop for preliminary crushing. After crushing, they are conveyed via a closed conveyor belt to the material bin in the grinding workshop, where they undergo fine powder processing using a Raymond mill. The processed materials are then sent to a mixing machine, where soft clay and additives are added to assist in the mixing process. Once mixed, the material is pressed into shape using a press. The semi-finished products, after being pressed and shaped, are stacked and dried, and finally sent to a tunnel kiln for firing and subsequent packaging.
