Trough Screw conveyor structure is simple, easy to operate, easy to maintain, widely used in metallurgy, mining, power, building materials, and other industries. In order to adapt to the changing situation, screw conveyors are constantly improved and subdivided into a variety of types. As per the Angle of conveying material displacement direction, the Screw conveyor is divided into a horizontal screw conveyor and vertical screw conveyor. According to the conveying materials, the screw conveyor can be divided into horizontal screw conveyor, vertical screw conveyor, flexible screw conveyor, and screw pipe (roller conveyor) conveyor. Advantages: it features a simple structure, reliable operation, and low maintenance cost. The tank is closed, which is easy to fly, hot (up to 2000℃) and strong-smelling materials, and less pollution to the environment. The conveying material can be loaded at any point of the line, and can also be unloaded at many points. The conveying mode is reversible, a Trough screw conveyor can transport materials to two aspects at the same time, and in the material conveying engineering can also complete mixing, cooling, and stirring processing. The rigidity of the feed groove is large, and it can bear certain bending moments well. Use: 1. Check the wear of spiral blades regularly, and repair welding or replacement of new parts can be used when serious wear is found. In addition, the wear of bearings should be regularly checked and the problems found should be replaced in time. 2, the lubrication parts of the conveyor should be strictly lubricated in accordance with the requirements, and often keep the lubricating oil of the internal bearings of the conveyor sufficient and regular replacement. 3, conveyor in the process of operation, once a harsh noise, should be a timely investigation. 4. The bearings at both ends of the conveyor should be strictly sealed to prevent dust from sticking. 5, pay close attention to monitoring the temperature exceeds the allowed, large, and water content of the material into the body, to prevent damage to the equipment. Fault:
1, the conveying material is too large, the material can not smoothly pass through the middle hanging bearing, the material resistance at the middle bearing is too large. Cause Trough screw conveyor to stop suddenly.
2, Trough screw conveyor  material infarction can also form motor overload operation lead to a shutdown. At this time clear the material in the Trough screw conveyor. 
3, the resistance at the middle bearing is too large, and the seal is damaged. The material enters the bearing to form the bearing does not rotate or the bearing is damaged.
4, the reducer bearing is burned. That's when you need new parts.
