- Mar 07, 2017 -

The main body of the concrete mixing station is the core part of the mixing station, and whether it can be used for the normal operation is the decision of the mixing station. Therefore, the mixer station maintenance and maintenance is crucial. The main mixer of concrete mixing station is composed of mixing drum and its auxiliary supporting parts. The mixing drum is a loading container for concrete, which is made of high quality wear-resistant steel plate. In order to be able to automatically install and unload concrete, the inner wall of the mixer is welded with special shaped spiral blades. When rotating concrete along the blade spiral direction, by mixing and stirring constantly upgrading and turning process. In the course of feeding and transportation, the mixing drum is rotating, the concrete moves along the blade, and when the material is discharged, the mixing drum is reversed, and the concrete is discharged outwards along the blade.

1, concrete mixer should be checked before each use of the project:

Check whether the fuselage is stable.

The connecting bolts on the blade and the blade support arm are firm.

Whether the connection bolt is fastened on the material rack.

Whether the water pump is sufficient, the pipeline is smooth.

2, concrete mixer should be checked after each use of the project:

Water supply device to keep clean, so as not to block the water valve to check the cleaning time.

Check whether the switch rocker arm loose, if loose should be adjusted.

Check the blade connection bolt, the support arm connection bolts are loose, adjust the gap between the blade and the cylinder wall maximum clearance 5mm and make the necessary tightening.

Check the contactor contact in the electric box.

Unscrew the blockage, check the shaft end seal, make the necessary adjustments to repair and replacement.
