Trough chain conveyors in Thermal waste treatment | Waste incineration
BG Series Scraper Conveyor Overview
1.BG series scraper conveyor is a continuous conveying mechanical equipment for conveying powdery and small granular dry materials, which can be arranged horizontally or inclined at a small angle.
2.The equipment has the advantages of simple structure, stable and reliable operation, long conveying distance, good sealing performance, low wear and low noise.
3.Its process layout is flexible, and it can add and unload materials at multiple points and realize quantitative conveying.
4.Because the shell is a fully enclosed structure, it has outstanding advantages in improving the operating conditions of workers and preventing environmental pollution when dealing with toxic, flying, explosive and high-temperature materials.
BG Series Scraper Conveyor Structural Features and Working Principle
1.BG series scraper conveyor is composed of head part, middle trough body, tail part, scraper conveyor chain, driving device and installation bolster beam.
2.Fully enclosed casing, no material leakage when the equipment is running; the conveying chain is made of high-quality alloy die forgings after heat treatment, which is strong and wear-resistant; the inlet and outlet of the equipment and the conveying length can be flexibly designed and arranged according to the process requirements.
3.The material enters the bottom of the tank evenly through the feeding port of the equipment, and is continuously and evenly transported from the feeding port to the discharge port by the load-bearing scraper conveyor chain that runs continuously from the tail to the machine head. It can realize multi-point feeding and multi-point unloading.
4.The tail of the machine is equipped with a screw adjustment device to adjust the tightness of the conveyor chain to ensure that it is always in a moderately tensioned state during operation, so that the equipment is in a stable operating state.
5.BG series scraper conveyors are suitable for conveying powdery and small granular dry materials with small abrasiveness and small accumulation specific gravity, such as steelmaking dust and dust from bag filter.
6.The BG series scraper conveyor produced by our company can be selected when conveying powdery, small particle and small block dry materials with high abrasiveness and high bulk density.
