Actual Operation

Effective Material TransferOptimized for smooth transfer of coal onto Boom ConveyorTransfer point sealed to eliminate dust Liners provided to prevent coal build-up or blockage

Optimization for BargesThe Continuous Unloader must efficiently unload from unevenly loaded coal barges. The upper layers of coal have peaks and valleys and the digging head must be designed to enable the buckets to be filled as much as possible.

The digging head is designed to fill the buckets as they move over the uneven surfaces of the upper layers.

Design of Digging HeadThe buckets should travel parallel to the material surface so they fill up to capacity.The buckets should travel along the surface for some distance so they can fill up.Our digging head design satisfies these requirements. d

Advantage:Efficient Operation

Bucket Elevator Swing

Advantage: Higher Efficiency

Bucket Elevator can swing in and out to access more material without moving the machine.Angle of digging head can be adjusted so the buckets travel parallel to the material surface.

Advantage: Efficient Operation

The digging head automatically adjusts itself so that the buckets can move horizontally when the Bucket Elevator swings in or out.

Dual-Mode Digging

Advantage: Higher Efficiency

Bucket Elevator can operate in both chain-tight and chain-loose modes. Chain-tight for normal digging and chain-loose for bottom clean-up Bucket-elevator canoperate in the mostefficient mode

Reducing Dust

Advantage: Clean Operation

Bucket Elevator column is fully enclosed, so there is no coal dust from unloading operation.
