Seven Hills Innovation

The Coal Handling Conveyor is a robust material transport system designed to efficiently move bulk coal from unloading areas to storage yards, crushers, bunkers, or boiler feeding units. These conveyors are crucial in automating coal flow in thermal power plants, improving reliability, reducing manpower, and ensuring safe and clean operation.
