Daily maintenance manual for large concrete mixing plant manufacturers

As a large concrete mixing plant, the maintenance and servicing of the main mixing machine is an effective means to restore the technical performance and prolong the service life of the main machine. Improper maintenance can reduce the reliability of the machine, lower the service life of the main machine, and even cause unnecessary mechanical accidents. So how to maintain the concrete mixing plant? Please see the daily maintenance manual of large concrete mixing plant manufacturer we bring to you.

 

Daily maintenance manual for large concrete mixing plant manufacturers.  

 

1. Requirements for the use of concrete raw materials   

 

HZS series concrete mixing plant adopts double horizontal shaft forced mixer, which can mix all kinds of hard, fluid, plastic and light aggregate concrete and mortar. The aggregate size for this series of mixing plant is less than 150 mm, and the aggregate size of 120-150 mm should not exceed 10% of the total capacity.   

 

2. Cleaning and maintenance of the mixing machine   

 

The mixing machine should be cleaned at least once in a working cycle. The mixing machine should be cleaned comprehensively at the end of production every day, by putting water and a little stone into the mixing machine for 5-10 min, and removing all the materials inside the machine after cleaning, no water or material should be accumulated; flushing the pipe after stopping, and removing the dust and adhering concrete inside and outside the mixing tank. Generally speaking, the JS1000 mixing machine should be filled with water about 150-180 kg, other models can be increased or decreased accordingly, or you can provide your own high-pressure water gun for cleaning.   

 

When flushing the material door of the mixing machine, avoid the phenomenon that the material accumulated under the upper flushing forms a foreign body stuck in the material door. During the mixing process, if the concrete truck is not in place for a long time (more than 20-30 min, especially in summer), water should be added to the mixer for simple cleaning.    During the normal production period, the solidification of concrete in the mixing cylinder and on the mixing shaft should be checked regularly, and if there is any solidification, it should be removed manually as required. Before cleaning the mixing cylinder manually, the power supply and air circuit must be cut off, the residual air must be released and the control room must be locked; when cleaning the mixing cylinder manually, it is strictly prohibited to hit the mixing shaft, mixing arm and mixing blade violently.
