First, the work of staff in the use of the day after the forced mixer bulk cement tank should be completed using the gate closed, all shipped out within the cement spiral, not any residual cement in the tube. Wash thoroughly with mechanical and field.
Second, the concrete mixing drum compulsory concrete mixer Nene must be clean and clean. Maintenance of machinery maintenance, filling each smooth point lubricating oil, to the need to maintain some oiled rust.
Third, cleaning compulsory mixer various parts of slurry fouling. Stirred tank and machine cleaned surface dust, concrete and oil buildup to prevent concrete dry, keeping clean. After the production, to promptly stop the mixer thoroughly cleaned before the remnants of concrete, will stop all operations switch to the isolation position, and turn off all the power switch.
Some customers think that after the completion of compulsory concrete mixer just stop on the line, and had such a strong-minded is a mistake for the timely elimination of concrete mixers security risks, ensure mixer status intact, so after the suspension to an excellent maintenance, it will not often The emergence of some small problems.

Concrete mixer Hefei two workers accidentally rotate instantly "bite"

November 12, 2014 in the afternoon, the city government at County Gang spent about three kilometers south of the place, inside a concrete batching plant, two men were concrete mixer legs bite through multi-sectoral rescue, one hour after the two men were rescued, one of them seriously injured.

How to analyze the quality of the Concrete Batching Plant identification

Concrete batching plant infrastructure in widespread use, many users knowledge of Concrete batching plant just limited to use for quality concrete batching plant is good or bad, is not very understanding, let alone to check the quality of the buying stations.

Concrete batching plant also that several major components, so long as these major part no quality problems, then this is not much concrete batching plant quality problems.

1. If the self-loading concrete mixer mixing tube that its discharge buckle circle runout does not exceed 1% of the diameter of the inlet, and also check the mixer shaker screen on the steel mesh and mesh quality and reasonable size and check the installation precision sieve;

2. The operation of the transmission system to be flexible, no abnormal noise;

3. belt conveyors, bucket elevators and other transmission dragline boom to have a smooth, running to be flexible, high brake can no unusual noise, no card chain;

The metering system also checks is very important to check the sensitivity and accuracy of measurement systems;

5. Reduce machine elevated temperatures should be noted that to achieve temperature-qualified book;

6. metering hopper out of material to be smooth, does not appear plot material, burrs and other phenomena;

7. safety valve leakage phenomenon can not occur;

8. quality cement tank qualified;

9. supporting line installation must be reasonable and installation of heavy equipment to be correct.
