The analysis of the causes of blocking phenomenon for cement screw

It aways cause blocking phenomenon when convey concrete,it could lead to machine failure. blocking phenomenon are mainly embodied in four aspects:
1.
The power is too small to do high strength work .

2.

The distance between blades is too close, The distance between blades should be  gradual transition, The distance between the feed port and the discharging port is bigger and bigger,so it is convenient for materials into or out.

3.
The elevation is too big, A 30-degree is the best choice in general case.

4.
Pay attention to waterproof for the machine, Cement will be agglomerate if there is water in the inside of machine,so clean the machine at regular intervals to to prevent blocking
