A brief talk on how asphalt mixing equipment is the grading and segregation of mixtures

In the course of road construction, it is bound to use asphalt mixer, presumably we will not be unfamiliar with this.
In addition to the overall quality of the machine, the selection and use of components also play a key role, will affect the construction quality and production costs.
The screen in asphalt mixer is used as an example to specify.

Highway construction needs to consume a large number of asphalt, gravel, cement, sand and other road building materials, the road surface after a certain number of years will be maintenance and overhaul, alteration, the original used to pave the surface of a large amount of materials will be turned into waste, when these waste is dug out all into nature, will be abandoned, pollution and material waste and other environmental
Asphalt pavement Regeneration Technology, is the need to renovate or discard the old asphalt pavement, after digging and recycling, crushing, screening, and the new materials, the appropriate coordination, re-mixing, the formation of a certain road performance of recycled Mobile Asphalt Plant mixture, used in road construction surface, the bottom layer or pavement base of the whole process technology.
The regeneration and utilization of old asphalt pavement has the following significance:
(1) Through asphalt regeneration technology on the old pavement asphalt concrete recycling recycling, its circulation is applied to highway new road construction and maintenance, waste into treasure, to avoid waste pavement material stacking on the land occupation and environmental pollution;
(2) so that the old asphalt concrete in the incomplete aging of asphalt, gravel, sand and other applications, can reduce the construction of asphalt pavement and maintenance of new asphalt resources and gravel material resources consumption, reduce the destruction of gravel material mining to the natural environment;
(3) Reduce the cost of road maintenance and renovation, save the cost of the project, shorten the construction period, improve the progress of asphalt pavement.
Therefore, the recycling and utilization of old asphalt pavement has important economic and social environmental benefits.

No matter what type of rational mixer, if the steel quality of its vibrating screen screen and the reasonable size of the sieve mesh and sieve hole, do not pay attention to the installation accuracy of the screen, and so on, the first stirring effect will not be ideal, and then affect the use of asphalt, so that the selection of high-quality higher wear-resistant screen is the basic condition for It can also reduce costs.

Some asphalt mixer manufacturing enterprises use cheaper ordinary steel manufacturing of inferior screen, ignoring the use of special wear-resistant steel wire weaving and carefully crafted wrapping process and other requirements, resulting in short service cycle, seriously affecting the normal operation of the unit.

Once the overall solution to the design has been determined, then there are some details about the problem.
Including processing technology, assembly process, packaging transport, economy, safety, reliability, practicality and other factors, and then to set the position of each component, structure shape and connection mode.
Moreover, in order to ensure the use of asphalt mixing station effect, will continue to improve, in the original design on the basis of perfect.

The function of the drum mixing device is a continuous system: there is no screening of raw materials, no separate weighing of raw materials and bitumen, and no separate mixing process, while in intermittent mixing equipment, raw materials are screened before mixing.

First of all, let me introduce some problems about the design.
We found that in the design of asphalt mixing station, we must first prepare for the work of construction market research, data analysis and other links.
Then according to the actual needs, the integration of these factors, but also to consider some innovative ideas, and finally optimize the selection of the most suitable practical program.
Then, you have to draw out a schematic of the scheme.

In general, there are many kinds of raw materials used in filter materials to meet different use needs, different raw materials have different characteristics, suitable application range or working environment are different.
Therefore, the principle of selecting asphalt mixing station and machine bag type Precipitator filter material is as follows: first, fully understand the physical and chemical characteristics of the dust-containing gas emitted in the production process, and then carefully analyze the technical properties of different fibers, in the selection.
In the selection of filter materials, the factors to be taken into account are: the physical and chemical characteristics of dust-containing gases, including temperature, humidity, corrosion, flammability and explosive.

All equipment has to be designed, manufactured and installed before it can work, asphalt mixing station is no exception, then in its design or installation process There are some precautions, do you know what it is?
