With the rapid development of China's basic construction, asphalt concrete mixing station and cement concrete mixing building have become necessary equipment in the construction and construction, and play an important role in the construction of the project.
Dust pollution of concrete mixing station has always been a difficult point of management, therefore, the traditional large concrete mixing station is mostly far away from the residential living quarters, built in convenient and remote local.

When we carry out some engineering construction, due to the difference of production situation, so it is necessary to choose the appropriate asphalt mixing station to carry out production, in order to achieve good returns, then in the selection of asphalt mixing station, the specific consideration should be taken into account those factors?

Asphalt mixing equipment, can also be called asphalt concrete mixing station.
Refers to the complete set of equipment used in bulk production of asphalt concrete.
According to the stirring method, it can be divided into intermittent and continuous type, according to the transfer method, can be divided into fixed type, semi-fixed type and Mobile Asphalt Mixing Plant type.

　　And the green concrete mixing station adopts the whole closed plan, and is equipped with the leading dust collection system, sandstone separation system and slurry water recovery system.
Its main building looks like a factory workshop, equipped with a perfect cycle system, the completion of waste water, waste, waste pulp zero emissions.
The accumulation of raw materials in concrete mixing stations is carried out indoors, and mixers work in indoor installations.
Transport vehicles in the factory and factory are in need of complete clean dust, completed the green production policy.

1, pay attention to routine inspection
Asphalt mixing equipment drying cylinder has been tested and inspected before leaving the factory, but in the process of transportation to the site, will withstand bumps and vibrations, should be used before the use of a comprehensive inspection: check whether all bolts have been tightened, all key pins are reliably entered, all the drive device is adjusted according to the manufacturer's instructions, all pipe connections are correct, Whether the fitting is safe and reliable; whether the whole machine is thoroughly lubricated; starts the motor and checks whether all the parts can rotate smoothly in the correct direction of rotation; whether the pressure gauge is working properly, if the safety valve is adjusted to the correct pressure; whether the burner ignition mechanism is applicable and whether the valve is open.

Users should choose according to the actual situation, first of all, to calculate the scale of production, to choose the corresponding asphalt mixing station production capacity.
If the annual output is less than 200,000, then the productivity of the asphalt mixing plant should not be less than 90m3/h; the annual output of more than 200,000 or less of 300,000, its productivity should be 120m3/h, the annual output of more than 300,000, the productivity is usually 150m3/h or 200m3/h.

About the price of equipment, is a problem that every user will consider, because this problem involves a lot of aspects, in the choice of asphalt mixing station, it is necessary to choose the most cost-effective products according to the actual situation.

2, second, the technical personnel must confirm the entire plant and its electrical system in the inspection process is normal, if abnormal situation, the user must check in time to eliminate safety hazards.

(3) Check the alignment of the cylinder body frequently.
Loosen the thrust roller first to check the degree to which the simplified energy can move within the length range of the slot on the support bracket.
Then start the drying cylinder, if the simplified front and rear movement, to check whether all the support rollers have been adjusted integrity.
If the supporting roller has been adjusted for integrity, and the cylinder gradually tends to feed end, then the thrust roller is temporarily biased (so that the drying cylinder is in the correct working angle), until the correct adjustment has been achieved.
If the cylinder gradually tends to unload the end, the thrust roller is adjusted in the opposite direction.

3. Reasonable maintenance and maintenance
(1) When the equipment is not in operation, the aggregate is not allowed to stay in the drying cylinder, each working day at the end, should operate the equipment to remove the aggregate in the drying cylinder clean.
When the aggregate in the tube is unloaded, the burner should be turned off and the simplified idling should be approximately 30min for cooling, thus minimizing its deformation or effect on the linear operation of the machine.

Aggregate directly from the Rolling Stone has almost constant water content, while the aggregate taken from the open-air yard has a higher water content, and the water content of different piles is also very varied.
Therefore, aggregates are best taken from the same source.
