ZLMGB series die-forged chain type scraper chip-conveyor is especially applicable to centralized discharging and disposal of the chips or powdery chips from machining shops. The die-forged knockdown chain has certain flexibility, which ensures an automatic lifting during operation when the scraper contacts such objects (non-chips) as bolts and taps, rather than lead to jamming. This is not what a roller-chain type scraper chip-conveyor can provide. This device is featured with simple structure, convenient maintenance and large chip conveyance.
