Improved screw conveyor

With China 's rapid economic development , the demand for cement is growing. Cement production, raw material conveying Screw conveyor is one of the devices . Screw in the

application hanging bearing often occur at blocking material, the flash conditions affecting production , economic efficiency decreases. For screw conveyor

Machine to analyze this situation : the food conveyor helical blade hanging bearing is that the role of the place, where not only will accumulate a lot of material , but also

in the box at the bottom of a lot of hard grinding granular material deposition , which is difficult to broken iron grain , coarse particulate material content of more, and

Very dense , so that both ends of the conveyor screw shaft friction blades severely , both ends of the blades wear more severe ; screw conveyor hanging bearing increased wear

and reduce service life. To solve the above problem, screw conveyor manufacturing has done in the following improvements:

At both ends of the screw shaft screw conveyor welding two helical blades , to strengthen the hanging bearing thrust plot material . Screw conveyor screw shaft rotation , thrust

generated twice the material , reducing the area of ​​the hanging bearing material, will not happen again blocking material, the flash phenomenon . Screw

The hanging bearing on the improvement in the process : hanging bearing wear-resistant materials ( such as iron ) made ​​; or steel castings , steel castings bore quenching,

coupled with the cylindrical axis of the middle section of quenching, after quenching grinding ; or hanging bearing bore and shaft coupling covered cylindrical electrode wear a

tie

Enhance the abrasion resistance , extending bearing life hanging . After improvement , screw conveyor hanging double the life of bearings , greatly reducing maintenance costs,

while reducing the cost of production of cement , increase economic efficiency.
