How To Build a Reasonable Asphalt Concrete Mixing Station Plant And Reduce The Cost

How To Build a Reasonable, Efficient Asphalt Concrete Mixing Station, And Improve The Quality Of Mixing And Reduce The Cost:

1 Site location and construction

Asphalt mixing equipment because of its own characteristics, demand for space from economic, convenience, safety, and environmental aspects of overall consideration.
(1)The ground for asphalt plant should choose slightly high, dry place the surrounding environment. Because the water content of raw materials for the production capacity of asphalt mixing equipment, mixing quality has very big effect. High moisture content, drying time is long, fuel consumption, loss of production, increase production cost. The MITNIK LB1000 asphalt mixing plant building as an example, sand stone moisture content is reduced by 3%, 1T per production finished product may reduce fuel 3L. In low-lying, stagnant water easily, so in construction of the field, should pay attention to the construction of the drainage pipeline and the construction of dry shed, the drainage capacity and the capacity of the dry shed should be fully estimated, avoid the continuous heavy rain, make the equipment be decimated.

(2)Geological Condition: Mixing station for large mechanical equipment, weight and material is very big, the quality of the equipment of institutions such as the feeding machine, dryer, mixing floor work are all in vibration state, so the geological requirements is hard, can effectively prevent the ground subsidence.

For soft ground foundation, its foundation and the surrounding foundation in mixing plant construction should be special treatment. While mixing machine for vibration body, should prevent resonance measures, avoid the harm to surrounding buildings.

3)The ground should choose the place with convenient transportation. Mixing plant to transport large amounts of raw materials and finished product mix, considering to reduce the cost and benefit at the construction.

(4)We should be considered in the construction of asphalt concrete construction temperature. Asphalt concrete mixing plant to construction site, with the increase of the distance, its temperature will reduce gradually, the road construction quality. Is a service municipal municipal mixing station location and as the maintenance of roads. Considering the mixing station asphalt concrete to the construction site of the time, should meet the construction requirements (in cold weather should do well in concrete cover insulation).
(5)Environmental factors. Asphalt mixing machine to stay away from homes and densely populated area. With the development of the city, the enlargement of city scale, asphalt mixing station distance closer to residential area. From recent or vision, mixing station should be particularly strict environmental protection, reduce harmful gas emissions, dust, noise, and increase investment in environmental protection, such as our bag dust removal device of building machine, and the construction of closed dry shed, dry heat adopt spray dust; Planting trees around walls, it is the key to the survival and development of asphalt mixing station.

(6) According to the topography site plan is determined. Including terrain contour plane and ranging from high plane. By using the topography reasonable layout can lay a good foundation for smooth production.

2.The selection of the mixing equipment

The choice of asphalt concrete mixing plant is a comprehensive comparison of many factors: the process of production capacity, power consumption, fuel type, electronic level, the technical parameters of equipment, environmental protection measures, maintenance, after-sales service, technical training, production technology, localization level and system, many aspects, thus the customers should be multiple perspectives analysis, comparison, mainly considering the manufacturers, production capacity, production technology advanced, economical and environmental factors.

(1)Manufacturers domestic and foreign products are: The production equipment is also part of the introduction of foreign products technology and standards, key components and the key technical performance of the system is relatively mature, the stability of the equipment is good, price is relatively low. Foreign product technical performance, the prices are high and the maintenance and after-sales service not in time.
(2)Model and the selection of production capacity. According to the construction scale and technical requirements for selection. In the lower level of asphalt concrete pavement paving work or small quantities in the pavement mending, choose portable small tonnage of asphalt concrete mixer, more technical standards generally low, backward technology, production of varieties of single and less advanced technology application, more than 100 t/h of the following products; The construction of urban road maintenance use comprehensive exercises more stationary asphalt concrete mixer; High grade highway use more comprehensive exercises semi-fixed asphalt concrete mixer.

After more than two products for more than 100 t/h products. From the technical requirements for urban road of new material, new technology and new technology requirements will be more and more high, choose corresponding production equipment technical requirements higher.

3 The Economic Operation
The diversity of fuel, the logistics of highly integrated automation and control system, which is beneficial to reduce the production cost, to achieve the economic operation of important factor. Fuel consumption is an important composition in asphalt concrete production cost, saving energy and reducing consumption is an important approach to achieve the economic operation.

By the moisture content is reduced by 4%, production per ton of asphalt concrete can save 3.6 L diesel, equivalent to about USD2. The other will directly reduce the production capacity of high moisture content, moisture content from 3% to 7%, the production capacity of 100t dropped to 60t. So, the moisture content of raw material should be as low as possible, when the raw material purchasing should choose when buying dry weather lasts longer, sand should be stored in large dry shed, to avoid the rain.Note: the environment temperature 15 ℃, altitude to sea level, the mixture of residual water content of 0.5% or less.

The choice of fuel, as global energy prices soaring, light oil price rise more, so the use of heavy oil burner manufacturer has become the research focus, the fuel filter, heating, high pressure atomized, combustion and self-cleaning nozzle technology mature gradually, but the strict maintenance equipment run time; Same and combustion heat value and heavy oil, heavy oil price to reduce 40%, so the economic benefit is obvious.

Asphalt mixing plant is mainly composed of cold aggregate supply system, drying heating system, elevator hot aggregate, aggregate screening and the loading metering device, powder supply, asphalt supply system and the metering device, mixer, finished product storage warehouse, dust removal equipment and control system, etc, is very large, highly integrated control system requirements, to achieve stable efficient concerted action between the agencies, personnel to high efficient logistics to automation, the maintenance cycle can be long, before the economic operation.
