The applicable cargoes of screw type ship unloader
Such as coal, fertilizer, grain, sulfur, coke, cement, phosphate rock powder, sugar, phosphate and other bulk dry cargoes, the maximum allowable block size (for coal) has reached 350mm; for materials that are easy to form hard shells such as cement, fertilizer, potassium salt, etc., its retrieving head is a reversing screw, which has the functions of loosening and retrieving materials, and can automatically dig in and retrieve materials, which well meets the needs of unloading ships; for unloading easily damaged materials such as grain, from the situation of using screw type ship unloader to unload grains in Europe, its crushing rate is 4-6% lower than that of pneumatic unloaders (vacuum grain suction machines), and it can well maintain the germination ability of grains and improve the economic benefits of grain depots. It has strong adaptability to cargoes, especially for handling cargoes with high dust, easy pollution, and easy compaction.
