Chain elevators turn the buckets upside down when emptying them (gravity discharging) and can therefore handle most sticky materials better than belt elevators. Despite this, they are mainly used for hot materials.
Chain elevators have limited capacity since the chain speed should not exceed 0.6 m/s.
The chains are conveyor chains with welded-on brackets.
Since chain elevators often work with highly abrasive materials, something which in turn causes wear on sprockets and chains, all sprockets are fitted with a three-section, replaceable sprocket wheel. This design allows the replacement of tooth sections without having to remove sprockets from the shaft.
The buckets are mounted between the chains and have end fasteners screwed to the chain brackets. These are normally produced with a reinforced digging edge. Available in different material grades.
