Introduction of Scraper Conveyor. Scraper conveyor is a kind of conveying equipment that continuously conveys powder, granule and small block materials in a closed shell by means of a moving scraper chain. It is suitable for closed conveying, the conveying volume is not too large, the process layout is complicated, and multi-point feeding or multi-point …
A screw in the horizontal is a conveyor or feeder, but as the screw is inclined it very quickly becomes a lift or pump. All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for …
A mechanical handling system called a drag chain conveyor, often referred to as a scraper conveyor or an en-masse conveyor, is made to move bulk goods vertically, horizontally, or at an incline. It is made out of a chain that travels down a row of parallel tubes or troughs that are lined with paddles or scraper blades.
