How Does an MS Chain Conveyor Work?
An MS Chain Conveyor works using a continuous chain and flight system that drags material through a sealed trough. The drag chain carries the material from the inlet to the discharge point while ensuring complete control and minimal degradation.
Working Mechanism:
Material Loading: Bulk materials enter the inlet chute or hopper.
Chain Movement: The drive station powers the drag chain and flights, propelling the material along the enclosed channel.
Controlled Transport: Scrapers push materials forward efficiently with minimal turbulence.
Material Discharge: The product exits through the outlet at a controlled flow rate.
Return Path: The chain returns via an enclosed lower channel, ready for another cycle.
This drag-and-scrape motion provides excellent control even at steep inclines, making it ideal for underground coal mines and grain silos.
