Sieving machine is used to separete solid waste such as sand, metal, small stone, labels in PET bottle recycling process. It helps the PET bottle washing by reducing equipment abrasion, material loss to enhance productivity. Flakes sieving improve the quality of final PET flakes. BoReTech supplys three types of sieving machines, dry trommel,disk screener and dust remover. Disk screener is more compact than the dry trommel, it can be placed after de-baling and pre-washing then remove sand, labels and so on. It can evenly disperse the bottles onto the next process and remove remained water. Dry trommel can remove caps and sands separately by multiple mesh sizes. Dust remover can separate dust in the flakes, small plastic labels and lm by taking advantage of the gravity and machine structure design.
