Coal as a material
Coal is a variable bulk material that can range from hard and dry to moist and friable, depending on origin and storage conditions. Its particle size, moisture content, and density influence how it breaks, flows, and discharges during unloading. These material characteristics affect penetration, bucket fill, dust behaviour, and wear on equipment, making the correct grab geometry and setup essential for reliable and efficient coal handling.
Coal handling challenges
Handling coal comes with inherent variability. Changes in moisture content, particle size, and density from one shipment to the next directly impact penetration, discharge behaviour, dust generation, and wear on handling equipment. At the same time, terminals are under constant pressure to maintain stable cycle times, control spillage and emissions, and limit unplanned downtime. Addressing these challenges requires handling solutions that can adapt to changing material conditions, support reliable operations, improve safety, and help meet environmental requirements.
Choosing the Right Grab
Choosing the correct grab is a critical step in ensuring efficient coal handling. Higher closing forces improve penetration in compact cargo, while robust wear packages and optimised geometry help reduce component wear and simplify final clean-up. For coal operations, solutions such as NemaX and Clamshell grabs support steady cycle times and long service life.
