The Advantages Of Continuous Ship Unloader

High Unloading Efficiency
The chain bucket ship unloader’s efficiency could reach over 65%, while the grab ship unloader could keep between 50% ～55%. The chain bucket ship unloader could change the shape of reclaiming head, which could reclaim the materials in maximum. Besides, the capacity of continuous ship unloader is larger than grab ship unloader by 20%.

Environmental Protection
The materials could be transported in sealing condition during the operation of the chain bucket ship unloader, which would not result in flying dust. The grab ship unloader would produce the flying dust during operation.

Energy Conservation
The chain bucket ship unloader has no frequent accelerating and decelerating, starting and braking, whose power consumption is reduced by 30% compared with grab ship unloader.

Small Follow-Up Investment
The chain bucket ship unloader could reach the rated capacity. If the rated capacity is 3 000 t/h, the following belt conveyor, stacker reclaimer’s capacity is 3 000 t/h. While the grab ship unloader’s related equipment need to reach 3 600 t/h. The cost is so high for EPC companies.

Types of cargo suitable for chain bucket continuous ship unloaders

Chain bucket unloaders can be used to unload materials such as limestone, coal, phosphate, ore sand, and raw sugar. Currently, the maximum unloading productivity in China has exceeded 4500t/h, and the maximum ship type for unloading is a 300000 ton seagoing vessel.

The chain bucket capacity of the chain bucket continuous ship unloader is relatively small, the structure of the reclaiming device is complex, and it is prone to blockage, making it unsuitable for unloading viscous materials. It is sensitive to oversized and irregular block materials, and the particle size of the unloaded materials is generally below 300mm.

Our Factory

The company has a 15,000m2 standard heavy-duty workshop, which is fully equipped with heavy-duty lathes, boring machines, drilling machines, etc. necessary for heavy-duty machining; in addition, it is also equipped with an independent sand-washing and paint workshop; in order to ensure that the products meet the high-quality requirements of European and American customers, the company has established an independent physical and chemical.

FAQ

How often should I inspect conveyor systems?

You should inspect certain basic components at the beginning and end of a shift. Walk around the equipment and look for anything that might be amiss, listen for funny noises, and look at the condition of the components of the basic parts that are running all the time.

Where in a conveyor can I achieve energy efficiencies with a retrofit?

Replacing an older motor with a newer, energy-efficient model is the best way to reduce energy usage. You should also be sure to clean the oil and gear lube. Doing so will make it run more energy-efficiently. You can increase a magnetic conveyor’s pulling power by upgrading the magnets.

How do I know when to rebuild or when to replace?

Each company has its own threshold as to when to replace a conveyor system, and it’s primarily based on cost. For some, if the cost to repair is 60 percent of a replacement, that is the threshold. Sometimes the threshold is as high as 70 percent of the cost of a new one.
Other times it’s a lead-time issue. A conveyor that can be repaired in two weeks may be more attractive than a new one that takes six weeks for delivery. Sometimes the decision is based on whether the cost can be taken out of a repair budget or a capital equipment budget.

What Kind of Conveyor Do I Need?

The type of conveyor required depends on several factors, including product type, dimensions, weights, location, and budget. By discussing these factors with our customers, we can provide the best recommendation based on the facts. It’s important to us that the final solution is a practical step forward in achieving the typical advantages that conveyors offer.

Do You Provide Installation?

Not all conveyors require installation. Some of our most effective systems can be simple scenarios, such as gravity roller conveyors. In these instances, we supply conveyors in flat-packed kits with fixings for customer installation.
Many of our belt conveyors can also be sent in similar kit forms. For example, conveyors used for end-of-line processes can be despatched fully built with electrical controls pre-fitted.
For integrated systems where groups of conveyors work together, we can advise on the installation process. We are able to organise our own contractors for mechanical installation and can arrange transport, hire machinery, and specialist contractors for specific tasks such as electrical automation and integration of warehouse management systems.

Can Conveyors Be Customised?

Yes, we offer customised conveyor solutions tailored to your specific needs. Whether you require a particular size, material, or special features, our team will work with you to design and build a conveyor system that meets your exact requirements.
