Well-known players include Marini, Ammann, Wirtgen, Astec, Liaoyuan Machinery, Nikko, Speco, Atlas, etc. Just like different workmanship and used materials leads to different service life span, different brand additional value and human resource cost massively influence pricing strategy.
So, it’s an important question whether your purchase decision is largely up to the brand you believe in, maybe groundlessly, or it is up to the facility itself. Where are you willing to throw your big bucks? Is it the price-performance ratio that you have been pursuing?
How To Opt For The Best Asphalt Mixing Plant?
There is not a certain one-for-all rule, and it varies from person to person just because the one most suitable for you is the best one for you. Having said that, there are still some guidelines needed to be taken into your consideration.
First, the quality grade requirement of final mixture. Usually, it's the local governments who dominate and supervise the infrastructure projects, so it's them who are the boss in terms of asphalt mix quality criteria. Complying to this quality standard should be the critical thing in your mind before next steps are taken.
Second, calculate the scale of your contracted projects seriously, and maybe you also need to anticipate that of the potential projects in the future. You cannot make a decision on the production capacity of AMP until the results come out.
Third, to buy a stationary one or to buy a portable one, is depended mainly on geographical conditions of your projects. If they are in the mountainous areas, or they are long and narrower, needing the matched facilities to relocate all the time, mobile asphalt plants, or even the super-mobile plants with excellent performance are regarded to be ideal.
Fourthly, if the authority is implementing some special environmental policies, maybe somewhat rigorous, dust filting system, as an integral part of your plant, becomes a crucial item you should give some special focus. Except that, other bio-friendly measures, such as enclosed mixing tower, recycling devices, can be adopted.
The last one, also the most important one, is your budget, for insufficient budget can make the above discussion nonsense.
New Technology Applied On Asphalt Plants
No matter it’s about warm mix asphalt, recycling, or retrofit and maintenance, the essence of the newest techniques embodied in AMP is how to lower energy consumption.
There is no difficulty in understanding that the players involved in the industry all have the incentives to fit this trend toward cost reduction and environmental concerns. The plant owners and contractors look to improve product availability and storage, which helps solve the fuel economy and environmental issues, while the manufacturers are embracing the technology that can help reduce costs, use less fuel, lower temperatures, allow the use of more RAP (Reclaimed Asphalt Pavement) and reduces emissions.
Other than the new techniques aiming at reduce the energy consumption and preserve the ecological environment, portability, flexibility, and intelligence are also the pursuits of asphalt plant manufacturing industry worldwide. After all, nobody is willing to spend more time and more labour force cost assembling a plant. As for batching hot mix plants, Installation, plus debugging and operator training, pushes the normal production back by at least half a mouth, while the portable and hypermobile hot mix plants, with ease of disassembly and assembly, and movement, shorten the production preparation time greatly. Self-erected modules, integrated units, and pre-wired design make installation and relocation a convenient experience. Between only some hours and half a month or even more than a month, which one you want to choose? In addition, towable feature helps achieve rapid transportion. Tappable interaction interface and automated control make operation more accurate and error-free. With these significant shifts, mobile asphalt plants, like our CMB, will definitely be favored by clients.
How To Control The Quality Of Asphalt Plant Output
Put it simply, asphalt is like glue, and it uses bitumen, an oil-based substance, to make sand and crushed rock stick to each other together. As a kind of commonly used road surface paving material, asphalt plays a vital part. It can be said that a roadway with a substandard blacktop material will fail prematurely. HMA producing plant, the equipment specialized in producing the road pavement materials, is the key tool for us to control the quality of asphalt. There are 7 aspects from which asphalt quality control starts.
1. Coarse Aggregate
Coarse aggregates are cube particles with rough surfaces and corners, and their particle size varies from 2.36mm to 25mm. To produce high-quality asphalt mixture, the content of sheet-like particles must be low, so that the interlocking effect of the particles can provide stability and resist displacement through friction.
2. Fine Aggregate
Fine aggregate refers to gravel with a particle size between 0.075 and 2.36 mm. When used as an ingredient to produce asphalt, it must be clean and free of clay and other harmful substances. It also should have some edges and corners to increase the interlocking effect between the particles and reduce the pores between the aggregates and ultimately increase the stability of the mixture.
Bitumen should be selected according to the local climate. The higher the grade of bitumen, the greater the penetration and the lower the consistency. It is suitable for areas with lower temperatures and the road surface has better low-temperature crack resistance but poor high-temperature stability. The higher the consistency of the bitumen, the higher the penetration PI index, and the higher the high temperature stability and rutting resistance of the pavement, but the poor thermal crack resistance.
4. Mixing Ratio Control
The design of the mixing ratio should be selected from repeated tests. After the quantity of each ingredient is determined, a Marshall test should be carried out to determine the optimal bitumen dosage, and thereby determine the proportion of other ingredients.
5. Temperature Control
Bitumen heating is controlled at 150～170℃. The temperature of mineral material is 10～20℃ higher than bitumen. The factory temperature of the final mixture is 140～155℃. When transported to the paver, the temperature is controlled between 135～150℃. The compaction temperature should not be lower than 135℃, the final compaction temperature should not be lower than 110℃, and the open traffic should not be higher than 60℃.
6. Oil-stone Ratio Control
The oil-stone ratio is the ratio of the quality of bitumen in asphalt concrete to the mass of additives such as sand. It is the most important indicator for controlling asphalt concrete. If the oil-stone ratio is too large, "oil cake" will appear after paving and rolling. If the ratio of oil stone is too small, the pavement material will diverge and it will not be formed by rolling.
It is required that all particles are wrapped by the bitumen, without uneven packaging, no agglomeration or serious segregation, and the mixture that is found to be charred, carbonized, foamed and water-containing must be discarded.
1. What is the maximum production capacity of asphalt mixing plants?
The batch mix type feature discontinuous production with intervals existing between batches. One batch generally takes 40-45 seconds due to the mixer, only after the mixture in which are all deschaged, the next batch commences. Constrained by such a characteristic, 450tons per hour can be regarded as the peak of the capacities of asphalt batching plants currently. As opposed to batch mix, the continuous hot mix plants' capacity can reach to 600t/h because of their unintermittent production.
2. How is the price of asphalt plant composed?
From the perspective of price conposion, an hot mix facility can roughly break down into welding parts and bought-in parts. Price of the former depends mainly on-the-spot price of the steel and processing cost. There is a huge gap between the giant manufacturers in those developed countries and other manufacturers. Bought-in parts like speed reducer, burners, bitumen pump, air compressor, commonly take up 50% of whole plant price.
3. What are the operating costs of hot mix plant?
It depends. Here is a set of rough figures you can take as reference. Over 75% of the total cost is related to raw materials (aggregates and bitumen), followed by the fuel cost, which is consumed in drying aggregates and heating bitumen, accounting for almost 12%. Transportation, installation, site construction, equipment maintenance, electricity, wheel loaders and labor add up to less than 10% of the total cost. The equipment procurement cost only occupies less than 2%.
