What should we pay attention to when purchasing road construction machinery and equipment? In addition, what are the differences between the use of bearings and their use in engineering machinery and mechanical engineering manufacturing? These are related questions about road construction machinery. Global Road Construction Machinery will give specific answers below.

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. 

Asphalt Mixing Plants Weighing Control System Operation Key Points
1. Turn on the power
Before connecting the power to the asphalt mixing station, you should first close the DC24V air switch (the air switch does not need to be cut off after shutting down), and then turn the "POWER CONTROL" (start switch) to the "ON" state. At this time, observe and check whether the "POWER" (red indicator light) on the panel is lit. If it is lit, it indicates that the power of the control system has been connected. Wait for about 1 minute and check whether the touch screen displays normally. If it displays normally, it means that the power supply is normal. Otherwise, it should be inspected.

Main uses of asphalt mixing plant
Asphalt mixing plant, also called asphalt concrete mixing plant, can produce asphalt mixture, modified asphalt mixture, and colorful asphalt mixture, fully meeting the needs of constructing expressways, graded highways, municipal roads, airports, ports, etc.
The overall composition of asphalt mixing plant
Asphalt mixing equipment mainly consists of batching system, drying system, incineration system, hot material improvement, vibrating screen, hot material storage bin, weighing mixing system, asphalt supply system, powder supply system, dust removal system, product silo and control system, etc. Some composition.

If an asphalt mixing plant wants to maintain normal operation, all aspects of the production process must remain normal. Among them, the normality of the circuit system is an important aspect to ensure its stable operation. Just imagine, if there is a problem with the circuit during the actual construction of the asphalt mixing station, it will affect the progress of the entire project.

During the construction process of pavement engineering, due to the complexity of the engineering situation, there are many kinds of problems that may occur. Among them, the asphalt mixing station is the key equipment in this project, so it should be paid enough attention to. Let’s take a look at the problems you may encounter.
