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.
Who Uses an MS Chain Conveyor?
The MS type buried scraper conveyor is widely used in:
Coal Mining: For continuous coal haulage and shearer positioning.
Grain Processing: Safe transport of wheat, corn, and soybeans.
Cement & Fertilizer Plants: Handling powders and granules.
Power Generation: Conveying fly ash and bottom ash.
Chemical & Metallurgical Industries: Moving bulk powders under controlled conditions.
