500DWT-100000DWT Orbital Mobile Screw Unloader Efficient Environmentally Friendly

The ATXL-B ship unloader adopts the orbital movement method. The screw ship unloader has a movable door seat that can walk longitudinally on the wharf track. It can perform unloading operations during the movement. When the cargo ship is berthed, the ship unloader can actively move. The warehouse has completed the unloading operation, and the mobility is outstanding.

Unloadable objects: powder and granular bulk materials such as cement, mineral powder, fly ash, fertilizer, and grain.
1. Wear-resistant: Powdery dry bulk materials are different from other types of materials. Due to the characteristics of high-speed screw conveying, the spiral blades and the wall of the spiral pipe are almost not worn, and only a few of the intermediate connecting shafts and their accessories of the screw conveyor are Components have wear resistance requirements. ATXL type screw ship unloader intermediate shaft and its accessories are made of high wear-resistant alloy materials with a number of patented technologies, and inlaid with carbide particles, with a service life of over 1 million tons.

2. Efficient: High-efficiency special reclaiming device and high-speed screw are used to continuously lift and convey materials. The height of the remaining material in the cabin is ≤250mm, the maximum unloading capacity is 1500 tons/hour, and the average operating efficiency is more than 70%.

3. Energy saving: Due to the continuity of material conveying of the screw ship unloader, it is easy to realize the whole process of closed-loop control and automatic adjustment from the reclaiming end to the discharging end, so that the ship unloader is always in the best working condition. Minimize the loss of reactive energy, so that the unit energy consumption is between 0.5-0.7KWH/h, reaching the level of energy saving.

4. Environmental protection: The screw ship unloader has a completely closed conveying system. During the operation, there will be no material leakage, and the impact of dust is strictly controlled to a minimum, which can meet the port industry and national emission standards. In addition, a reclaiming dust suppression device can be selected to minimize the dust flying during the reclaiming process.
