| Asphalt mixing machine factory mix hot reproducing apparatus |
| Evaluation of pretreatment and measurement methods of the old asphalt recycling materials intermittent feeding equipment and measurement methods intermittent renewable equipment new aggregate after drying by secondary screening and weighing can be made more accurate, but the old measurement of asphalt mixture is completely lost intermittent equipment on which rule the roost advantage: the aggregate of the old asphalt recycling compound can not conduct a secondary screening, and that such intermittent mixing equipment can not be old asphalt mixture to provide an accurate measurement of The old asphalt material (heated viscous so that measurement difficulties, slow speed, accuracy difficult to control).
Thus, the gradation control advantages of of intermittent renewable mixing equipment in the need to deal with a large proportion of the old asphalt mixture has ceased to exist. The intermittent feeding equipment and measurement sequence is: Cold Aggregate Batching aggregate drying aggregate the hot screening Thermal Aggregate weighing stirring.
The continuous equipment recycling of old asphalt material feeding and measurement methods of evaluation continuous stirring the advantages of the equipment is well known, it is high efficiency, large output, low energy consumption, high reliability, continuous mixing equipment, measurement accuracy , whether it can be used in the asphalt mixture Mix doubt. But affect the finished level with accuracy, not only the accuracy of the weighing system itself is good, but also with the specifications of the raw materials (aggregate) related. Thus, continuous mixing equipment whether aggregate secondary screening has become one of the keys to its ability to be used in more demanding asphalt concrete production.
1) double drum continuous feeding equipment and metering. The double roller continuous performance of the device does not have a secondary screening, feeding and metering order: Cold Aggregate Batching cold Aggregate weighing aggregate drying stirring.
2) continuous double drum equipment Guangfo improved feeding and metering. Continuous mixing continuous mixing principle has been getting to know the accuracy of continuous measurement be sure, but the poor quality of highway engineering materials, specifications and bad, continuous mixing equipment, unlike the batch mixing equipment once the hot aggregate screening can guarantee graded accurately. In order to solve the continuous asphalt concrete mixing equipment for mixing and unstable source or quality of engineering materials, aggregate, can still guarantee to get the right mix gradation, reach secondary screening batch asphalt mixing plant effect. Guangfo highway maintenance, while the introduction of double drum set of aggregate pre-classification processing that is cold aggregate screening process that Cold Aggregate Batching device top plus two flat sieve, cold aggregate for screening. This device has been put to use, whether for asphalt recycling, or stirring new asphalt concrete, reached the intended purpose.
Visible to the improved continuous reproducing apparatus and intermittent reproduction apparatus contrast, the improved continuous reproducing apparatus of the intermittent flow of aggregate hot screening aggregate cold sieving becomes continuous process, can make continuous process with intermittent flow, with the function of the aggregate the gatekeeper (secondary screening). Two asphalt mixing process is identical to the processing of the aggregate, only advance to the drying step in the sequence will be the original hot screening weighing before, becomes now the cold screening weighing.
Double drum asphalt mixing plant in the cost advantages of the production capacity of the manufacturing cost of the field of batch mixing equipment mainly depends on the capacity of stirring the pot, stirring the pot filling rate certain conditions, the mixing tower weight is generally stirring the pot capacity that is proportional to the production capacity. Since this part of the weight of a large proportion of the entire weight of the equipment, batch equipment than the weight coefficient (weight of equipment / production capacity) With the increase in equipment production capacity will decline, but its downward trend slow. For double drum mixing equipment, its production capacity is substantially proportional to the square of the drum diameter.
Therefore, as the diameter increases, the production capacity of the equipment will rise sharply. This means that the double drum mixing equipment on the metallic material, the amount of consumption of energy, labor and manufacturing costs relative to the advantages of the batch-type equipment with the increase of the production capacity and more significant. Visible double drum mixing equipment to increase production capacity and reduce manufacturing costs, there is a huge potential advantage.
The field of the use of cost The double drum mixing equipment to produce 1t mix due to the savings in maintenance costs, fuel costs, depreciation costs, cost about 10% lower than the batch mixing equipment, such as from the point of view of society as a whole This savings will be relatively considerable.
Suggestions for improvement of the hot asphalt recycling mixing equipment factory thermal asphalt pavement recycling equipment is a practical but also ensures that the quality of the asphalt pavement recycling equipment, factory thermal regeneration can fully meet the technical standards of highway asphalt pavement. This device can be used to the regeneration of asphalt pavement, and can also be used for the construction of a new asphalt pavement. Regeneration development factory hot asphalt concrete recycling equipment and technology is in line with the actual situation in Shanxi Province.
Batch asphalt mixing equipment and continuous double drum asphalt mixing equipment detailed comparative analysis, looking for an intermittent and continuous benefits can take full advantage and play, mixing high-quality hot asphalt recycling mix , research and development of better, more adapted to the mixing equipment of the province's roads. | | |  |
