  Technical features

  It is composed of a closed tank and a screw by a driving device, and the coal in the tank is pushed out by the screw rotation.

  It is characterized by simple structure, small cross-section size, good sealing performance, reliable operation, low manufacturing cost, convenient for intermediate loading and unloading, and the conveying direction can be reversed or two opposite directions at the same time. During transportation, materials can also be stirred, mixed, heated and cooled. The material flow can be adjusted through the loading and unloading gate. However, it is not suitable to transport materials that are easy to deteriorate, sticky, caking and bulky. In the process of conveying, the material is easy to be broken, and the screw and trough are easy to wear. The unit power is larger. In use, it is necessary to keep the tightness of the material groove and to keep a proper gap between the screw and the material groove.

  Vertical screw conveyor is suitable for short distance vertical transportation. The screw of flexible screw conveyor is composed of flexible shaft and synthetic rubber blade, which is easy to bend. It can be arranged arbitrarily according to site or process requirements for space transportation. The blade of screw conveyor has pull-in type and integral pull-out loss. The pull-in type can be made of any thickness and size, and the whole pull type is not suitable for making non-standard screw.


  From the perspective of material displacement direction, Hongtai screw conveyor can be divided into horizontal screw conveyor and vertical screw conveyor. It is mainly used for horizontal transportation and vertical lifting of various loose materials such as powder, granular and small pieces. The screw conveyor is not suitable for conveying easily deteriorated, sticky, caking or high temperature, pressure fear and corrosion Special materials.

  Screw conveyor is generally composed of conveyor body, material inlet and outlet and driving device; screw blade of screw conveyor has three forms: solid spiral surface, belt type spiral surface and blade spiral surface. Among them, blade type spiral surface is relatively less used, mainly used for conveying materials with high viscosity and compressibility. This type of screw suspension surface, in the process of completing the conveying operation, is the same With and complete the material mixing, mixing and other functions.
