Drying drum is a cold and wet aggregate drying heating device.
In order to make cold and wet aggregate in a short period of time, to ensure that preheating, dehydration drying, heating warming three stages of orderly, required aggregate distribution in the drum, the movement of each section is reasonable, and there is sufficient running time in the cylinder to ensure that its discharge temperature to meet the requirements, but also to consider that the flame must have sufficient combustion space.

One of the factors affecting the temperature of the mixture is the quality of the fuel.
If the quality of the fuel is poor, the calorific value is low, the combustion is not sufficient, it will cause the stone heating instability, low temperature, the residual material retained in the mixture, seriously affecting the quality of the mixture.
If the fuel viscosity is too large, the impurity content is more, the water content is large, will cause the ignition difficulty, the pipe blockage, the temperature is difficult to control.
The moisture content of raw materials is another factor affecting temperature.
Raw material moisture content is large, and uneven, in the production process, stone heating temperature is difficult to control.
In addition, the technical status of the combustion system, the pressure of the fuel pump, and the size of the oil injection are related to the temperature of the mixture.
The wear, leakage, blockage and other faults of the combustion system make the parts can not maintain the original performance, resulting in low pressure of the system, unstable oil supply, poor atomization combustion effect, will also seriously affect the mixing temperature.

To sum up, in the process of using asphalt mixing station, at the same time coordinate the work of the external factors related to it, will show better results for the actual use, at the same time, this is also the focus of the work.

Asphalt is a kind of material commonly used in road construction in China at present, which has certain influence on the quality and benefit of road engineering.
As an important road surface laying material, in the use of the degree of demand is relatively high, the overall effect of the presentation has been a good help.
Asphalt Mixing station is an indispensable key equipment for the production and use of such products.

n

This also provides excellent equipment performance support for our urban highway construction, asphalt mixing station on the basis of its own utility, to the actual modern urban highway construction has brought great convenience.
It is also by virtue of such demand characteristics, more convenient for the overall use of mechanical products to implement the implementation, the use of the relevant details of the function.

When replacing the screen, you need to open the front back door, loosen the nut, relax the sieve slant compaction mechanism, remove the screen from the pull hook, you can pull out from the front door.
The procedure, in turn, can be fitted with a changing screen.
Regularly open the spring observation hole, observe the spring working status, anti-detachment soft pull is good, if there is a problem in time to repair.

n

With its own excellent performance, today, has been in the existing market scope has been better expansion results.
For asphalt mixing stations, some external factors that may have an impact on their work also need to be coordinated, even the impact on the work is more critical, therefore, the relationship between the treatment of various factors has a significant impact.

n

From the characteristics of asphalt such products themselves, the work, the need for continuous heating stirring, in order to be able to make it in a more suitable transport use of the state.
The satisfaction of asphalt mixing stations at this point is relatively adequate, as such products become liquid in the form of external temperatures falling.
With such characteristics as the starting point, in the process of work, to give a stable heating to ensure transport and practical use.
Thus also conducive to our urban highway construction can have a better efficiency improvement, the use of this equipment is very critical.
Coordinate the actual external functional requirements, good results can be presented.

The treatment is: first with hammer knock on the roller, if continue to operate, then temporarily do not consider, if any way, to confirm that it can not turn, then the roller must be unloaded to deal with.
First, the shaft on both sides of the roller with a retaining ring, and then remove the two ends of the block, Labyrinth Seal, the shaft from one end out, remove the bearing, observe the bearing and labyrinth seal whether there is still use value, such as available, then with gasoline to clean the bearing, put on the appropriate amount of lubricating oil, re-assembly can be ; If the bearing and labyrinth seals are badly worn and have no use value, then they must be replaced with new.
