How should the drying heating system of asphalt mixing station be set? - 09 Dec 2018 10:11


Therefore, we are here today to share some experience and skills on asphalt mixing stations in order to better help you solve some problems at an early date.

Below we will summarize the content to share with you, for your reference.

Drying heating system can be regarded as an important part of the whole asphalt mixing plant, so it is in the actual work, is in the way of countercurrent heating to deal with the material, so as to achieve full dehydration of cold aggregate, but also to heat it to a certain temperature, thus providing the necessary conditions for the normal and continuous operation of the asphalt mixing station.

Because for the asphalt mixing process, only to ensure the normal operation of the heating system, can provide a guarantee for the operation of the entire system, in order to provide the necessary basis for subsequent production, to meet the production requirements of asphalt mixing station.

The combustion device of the asphalt mixing station is used to provide a heat source for the drying and heating of cold aggregate, that is to say, in addition to the need to select the right fuel, it is necessary to select a suitable burner for the asphalt mixing station.

In order to ensure the effect of heating the asphalt mixing station, in addition to the above two devices to be reasonably selected, but also need to take a certain amount of insulation measures.

Asphalt mixer also has a commutator valve, the general situation will not appear problems, so before also did not carefully understand its solution.

But in the actual use of the time, but encountered this aspect of the failure, how to deal with it?Asphalt mixer Commutator valve failure is not complex, that is, the conversion is not timely, gas leakage, electromagnetic pilot valve failure and so on, the corresponding reasons and solutions are of course different.

In order to change the commutative valve is not timely phenomenon, generally because of poor smoothness, spring jammed or damaged, oil or impurities stuck in the sliding part, etc.

, it is necessary to check the status of the oil mist, lubricating oil viscosity, the need to replace lubricating oil or other parts.

  Asphalt concrete Mixing station in the course of operation to have operators to operate, requiring employees have received the post of professional training in the relevant technology, and passed the qualification examination and obtained the operation Certificate of the equipment.

nFirst of all, for different problems, we need to analyze according to the specific reasons, and then take appropriate measures to deal with.

For example, if there is a problem of fatigue damage in some parts of the asphalt mixing station, then how should we deal with it? The best solution to this situation is to start with the manufacture of these parts, such as improving the finish of the parts surface, and to improve the performance of these components by reducing the stress concentration problems of the parts.

In this way, in the use of the process, you can effectively reduce the probability of fatigue damage to the parts.

  Lontto GROUP Company mainly produces and manufactures stable soil mixing stations, stable soil mixing stations, stable soil mixing equipment, concrete mixing stations, water-stabilized mixing stations, two ash mixing stations, graded gravel mixing stations and other leading products, high quality and low price, welcome customers to visit,.

The content of the assessment should have the following security system, the task of the work, whether the equipment operation mode is safe, the internal security facilities have not been well maintained and so on.

Electrical-control-system-control-room-300x197.jpg After a long period of use, the commutator valve is prone to valve core seal ring wear, stem and seat damage phenomenon, resulting in gas leakage in the valve.

At this point, the seal ring, stem and seat should be replaced, or the commutator valve should be changed directly for new.

In order to reduce the failure rate of asphalt mixer, usually also need to strengthen maintenance.

nThere is also a situation, if in the production process, these components only simply have friction problems, then how to deal with it? There are two ways to solve this problem, namely: 1, in the production of these parts, as far as possible to use wear-resistant materials, 2, in the design of these asphalt mixing plant used in the shape of the parts, should also take into account the problem of reducing friction resistance.

Attention should be paid to the test error, which should be combined with the actual effect after paving and rolling.

A trial production can not be concluded that equipment control is accurate, should be in the same specification after the cumulative output of 2000t, 5000t, computer statistics, the actual number of materials consumed, the number of finished products and test data together to analyze, in order to draw conclusions.

The precision of asphalt drum Mix plant metering of large asphalt mixture mixing equipment should reach ±0.25%, if this scope is not reached, the cause should be found out and resolved. - Comments: 0

What are the requirements of the operator of the asphalt mixing station? - 02 Dec 2018 14:48


At the same time as the demand for fuel changes, the quality requirements of burners are becoming more and more high, good ignition performance, efficient combustion efficiency, wide adjustment ratio, is often the goal of the construction units of each bridge crane Chase.But burner manufacturers are numerous, different brands, only the appropriate choice, in order to meet the above requirements.

After years of development, we have accumulated a wealth of sales channels and sales experience, partners all over the north and south.
In the new year, we will make full use of and develop our own sales platform advantages, with more manufacturers to establish strategic partnership.
In particular, we will be closely integrated with the advantages of product R d Wuxi Ya Road, to promote the sales of Wuxi Ya LU Machinery series products, the completion of sales advantages and R d Advantages of Perfect match.

In fact, for the operation of the asphalt mixing station, we must implement it with strict standards, not only to ensure the successful completion of the whole project, but also to ensure the personal safety of our staff.

Therefore, in the operation of equipment, we must require operators should meet certain standards in order to be on the job, the following we will introduce the specific requirements and standards.

In short, all the requirements for operators are in fact to ensure that our production work can be successfully completed, but also to effectively ensure the personal safety of our staff, but also to protect our asphalt mixing plant equipment as far as possible.

(2) Dielectric atomization is through the compressed air of 5~8kg or with pressure vapor pressure to the periphery of the nozzle and fuel pre-mixed combustion, characterized by low fuel requirements (such as residue and other poor oil), but more consumables, higher costs, the current road construction machinery industry using this type of aircraft less.

(3) The Rotary Cup atomization is through a high-speed rotary cup plate (about 6000 rpm) to the fuel out of the atomization.

Can burn poor oil, such as high viscosity slag oil and so on.

But the model is expensive, and the rotary Cup plate is easy to wear, the debugging requirements are very high.

At present, the road construction machinery industry basically do not use this type of aircraft.

1.2 burner According to the machine structure can be divided into all-in-one gun machine and split gun machine(3) The filter installed between the tank and the oil pump shall be cleaned regularly and checked for excessive wear and tear to ensure that the fuel reaches the pump smoothly from the tank and reduces the possibility of failure of the potential components.

The "Y" filter on the burner should be cleaned frequently, especially when heavy oil or residue is used, to prevent clogging of the injector and valve.

When working, check the pressure gauge on the burner to see if it is within the normal range.


Learning, enterprising and innovation are the essence of Wuxi ya Lu's corporate culture.

It is this spirit of inspiration, we will never pause, closely follow the pace of market development, and constantly adjust, optimize the business structure, always maintain a leading position in the construction road equipment industry.

Accompanied by a new starting point quietly, is our new stage of development and broad prospects for development.


As asphalt production equipment, asphalt mixers consist of mixing systems, drying systems, combustion systems, heat storage, thermal material lifting, vibrating screens, weighing and mixing systems, asphalt supply systems, powder feeding systems, dust removal systems, finished product silos and control systems.

General Asphalt mixing plants in the construction of our expressway and municipal roads, airports, port roads to play a major role, today by our Ya Lu project we tell you how to choose asphalt Mixing station manufacturers.

First of all, our requirements for operators are that they must undergo professional technical training, and passed the qualification examination and obtained the asphalt mixing station operating documents.

Secondly, an examination should also be arranged on a regular basis to check its safety awareness.

The main contents of the examination are: 1, the security system, 2, the task related to the work, 3, whether the operation mode of the equipment is correct and reasonable, 4, whether the internal safety facilities are reasonable maintenance and so on.

In fact, as an operator, we have to be clear about the main responsibilities of the job, and we must also have certain considerations, as well as preventive measures.

In addition, in the event of some emergencies, there should also be some skills to deal with the problem, which are used as asphalt mixing station operators should meet the requirements.

Asphalt concrete mixing equipment in the process of use, it is easy to produce dust pollution, not only will affect the stirring effect and the normal operation of equipment, but also to the environment and personnel caused harm.

Therefore, in order to prevent two pollution of dust, to avoid damage to the body, must be in the asphalt concrete mixing equipment to set up the necessary dust removal device, play the role of Dustproof. - Comments: 0
