The solution for the extruder not eating the material

The development of the industry is more and more inseparable from the cooperation of the extruder. While cooperating with each other, it will be found that the extruder does not eat the material, which requires a series of solutions.

1.The surface of the reamer blade is too rough, increasing the friction between the mud and the blade: do not surfacing in groups when surfacing the reamer, replace it all at one time, and replace it gradually and in batches to ensure smooth brick production. Conditional can be slightly polished smooth.

2. When the extruder does not feed, the reamer is seriously worn. The gap between the reamer and the inner wall of the mud tank is too large, or the helix angle of the reamer blade is wrong: when replacing the reamer, care should be taken to keep the gap at 3-5mm, and the reamer blade should be made according to the designed angle.

3. The gap between the mud pressing blade and the reamer is too large to press down the mud: the blade should be adjusted or repaired, and the blade should be updated to make the gap between the blade and the reamer less than 10mm.

4. The lining of the extruder mud tank wall is seriously worn. The gap between the reamer blade and the mud tank wall is too large, resulting in too much rotary motion of the mud in the mud tank, and the mud cannot come out or enter: at this time, a new mud tank liner should be replaced, or another Several ribs parallel or inclined to the axial direction are installed on the inner wall of the bushing to replace the reciprocating grooves that have been ground off, preventing the ineffective rotation of the mud and increasing its effective extrusion.

It is actually quite normal for the plastic extruder to not eat the material. It may be that the material is too full, which makes it unable to operate. As long as it is updated and blocked in time, it can operate normally.
