Products Description


The chain bucket ship unloader is a continuous bulk material unloading machine that uses a chain bucket to dig out materials from the cabin of a seagoing ship and unload the materials to the dock through the on-board conveyor system. Our company can produce L-shaped chain bucket ship unloaders and catenary chain bucket ship unloaders. It can be used for unloading limestone, coal, phosphate, ore sand, raw sugar, and other materials. The maximum production efficiency of ship unloading can reach up to 3000t/h, and the maximum unloading ship is 100,000t degree sea ship.


L-shaped chain bucket ship unloader, the chain bucket digs out the materials and lifts them to the top. The materials are unloaded on the boom belt conveyor through the spiral hopper unloader and transported to the rear. The L-shaped reclaiming head can rotate, and the boom can tilt and rotate. Through automatic control, it can be ensured that the reclaiming head moves according to a certain route. The L-shaped chain bucket ship unloader has requirements for water level, ship type, and wharf gauge. Since this equipment has a large operating area, it is suitable for ships of no less than 50,000 tons, and the wharf gauge is no less than 14 meters.

Catenary chain bucket ship unloader, which is suitable for deck barges. The chain bucket of the catenary chain bucket ship unloader has no rigid bracket in the material retrieval section and is suspended. The hopper operating on the deck can float up and down with the deck when the ship is bumpy, so the hopper can be close to the cabin. Face to face work, with the ability to clear goods. The catenary ship unloader has requirements for water level and ship type. The difference in water level should not exceed 5 meters, so it is suitable for flat barges.

Features & Advantages


Compared with traditional grab ship unloaders, it has the following advantages:


* High Ship Unloading Efficiency: The average ship unloading efficiency of chain bucket ship unloaders, including the clearance stage, can reach more than 55% to 60% of the rated productivity, while grab ship unloaders usually only have 45% to 50%. The chain bucket ship unloader can change the shape of the material reclaiming head to maximize material recovery.


* Environmental Protection: When the chain bucket ship unloader is operating, materials can be transported in a sealed state without causing flying dust. There are no frequent starting and braking operations during work, so the noise is not large. The grab ship unloader will produce flying dust during the operation.


* Energy Conservation: The chain bucket ship unloader does not need frequent acceleration, deceleration, starting, and braking, and its power consumption is 30% lower than that of the grab ship unloader. According to statistics, the energy consumption of chain bucket ship unloaders is 1MJ/t~1.26MJ/t, while the energy consumption of grab ship unloaders is 1.62MJ/t~1.8MJ/t.


* Small Mass: Its mass is generally smaller than that of a grab ship unloader with the same outreach and productivity (especially a trolley-type grab ship unloader).


* Stable Operation: Continuous working method, stable operation.


* Automated Operation: The ship unloader has a similar reclaiming process in every layer of the working surface, it is convenient to make operation and easy to realize the automation.
