This machine is used at the preparation section of the manufacturing process. It is used for eliminating stones, lime stones and other foreign materials out of the raw material at the brick and roofing tile plants. The screen holes can be implemented at different diameters according to the needs. The raw material passing through the screens is transferred at the required direction by the conveyor belt mounted at the bottom of the machine. This raw material has the required size. The bigger sized material that cannot pass through the screens are transferred to the waste section or recycled to the hammer crusher, if any, before the rotary dryer depending on the demand of the user.
