Sewage treatment accessories, 304 equal-thickness auger spiral blades with shaft, left-hand and right-hand rotation. When materials are fed into the fixed trough, due to gravity and friction between the materials and the trough, the materials accumulated at the bottom do not rotate with the spiral body. Instead, they are pushed forward by the rotating spiral blades, similar to a non-rotating nut moving along a rotating screw, achieving the purpose of conveying materials. This machine facilitates multi-point loading and unloading, and can simultaneously complete mixing, stirring, or cooling functions during transportation. It is sensitive to overload and prone to clogging; it causes some crushing and wear to materials. The horizontal screw conveyor has a simple structure, making it easy to install, maintain, and troubleshoot. It is suitable for continuous and uniform conveying of loose materials horizontally or with a slight inclination (20o or less). The operating environment temperature ranges from -20 to +40℃, and the material temperature ranges from -20 to +80℃. Its rotational speed is relatively lower compared to vertical conveyors, mainly used for horizontal or small-angle material conveying, with a conveying distance generally not exceeding 70 meters.

The rotational speed of the vertical screw conveyor's spiral body is higher than that of ordinary screw conveyors. The fed materials, under centrifugal force, generate friction with the casing. This friction prevents the materials from rotating with the spiral blades and overcomes the gravity of material descent, thereby achieving vertical material conveying. This machine has a small conveying capacity, limited conveying height, high rotational speed, and high energy consumption. It is particularly suitable for conveying large items. Spiral conveyors are categorized based on the direction of material displacement into horizontal screw conveyors and vertical screw conveyors. Those with conveying chains made of high-strength plastic are also known as food spiral conveyors or spiral elevators, mainly suitable for conveying large items such as cartons, turnover boxes, and bottled water. Depending on the characteristics of the materials and structural requirements, spiral conveyors include horizontal screw conveyors, vertical screw conveyors, flexible screw conveyors, and spiral tube (roller conveyor) conveyors.
