Safety standards for small asphalt mixers
1. Small asphalt mixer
It should be installed in a flat position, and square wood should be used to cushion the front and rear axles so that the tires are elevated to avoid movement when starting. 
2. Small asphalt mixers should be subject to secondary leakage protection. After the power is turned on before going to work, they must be carefully inspected. After an empty test run, they are found to be qualified before they can be used. During trial operation, it should be checked whether the mixing drum speed is appropriate. Under normal circumstances, the speed of the empty truck is slightly faster than that of the heavy truck (after loading) by 2 to 3 revolutions. If the difference is large, the ratio of the moving wheel and the transmission wheel should be adjusted.

3. The rotation direction of the mixing drum should be in line with the direction indicated by the arrow. If not, the motor wiring should be corrected. 
4. Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is protruding, whether there are any obstacles around it and the lubrication condition of various parts, etc.
5. After starting up, always pay attention to whether the various parts of the mixer are working normally. When shutting down, always check whether the mixer blades are bent and whether the screws are knocked off or loose. 
6. When the concrete mixing is completed or is expected to stop for more than 1 hour, in addition to removing the remaining materials, use stones and water to pour into the shaking barrel, start the machine and start rolling, rinse away the mortar stuck to the barrel, and then discharge all the mortar. There must be no accumulation of water in the barrel to prevent the barrel and blades from rusting. At the same time, dust accumulation outside the mixing cylinder should also be cleaned up to keep the machine clean and intact.
7. After get off work and when the machine is not in use, the power should be turned off and the switch box should be locked to ensure safety.
