Screw ship unloader is a ship unloader with horizontal screw conveyor, vertical screw conveyor and special reclaiming device without flexible traction components as the main working mechanism. Let's take a look at its features!
1. Simple structure and low quality. The material conveying system of the Screw ship unloader is composed of screw conveyors without flexible traction components. The conveyor has no return branch, and the structure is relatively simple. The vertical arm and the horizontal arm have smaller cross-sectional dimensions. Under the same conditions of productivity as the target ship, the mass of the screw ship unloader is much smaller than that of the grab ship unloader, and it is also the smallest mass of various mechanical continuous ship unloaders. Therefore, the cost of the Screw ship unloader is lower, and the requirements for the carrying capacity of the terminal are lower.
2. Strong adaptability to cargo and ship type. Screw ship unloader can be used to unload various powder, granular and block materials. When unloading some materials that are compacted or even formed into a hard shell after being transported by sea, such as fertilizer, cement, potash, etc., due to the unloading device The reversing reclaiming screw or loosening knife installed on the outside has the function of loosening materials, which can well meet the requirements of unloading. The vertical part of the Screw ship unloader has a small cross-sectional size, and auxiliary mechanisms such as walking, turning, pitching, and swinging ensure the machine's flexible movement. It can be suitable for various types of barges and sea ships.
3. Small environmental pollution. The material conveying system of Screw ship unloader is fully enclosed, and there is no material dust and no leakage of material or material odor during the unloading operation. For the unloading of materials that are easy to pollute the air, such as cement, pulverized coal, chalk powder, potassium salt, ammonium phosphate, etc., the use of Screw ship unloader is particularly advantageous.
