　　In the asphalt pavement recycling technology system, factory run cold recycling, as a core process parallel to on-site cold recycling, has become an important choice for highway maintenance and renovation projects due to its advantages such as stable gradation of finished materials, high utilization rate of recycled materials, and controllable construction costs. Unlike the on-site processing and paving mode of on-site cold recycling, factory cold recycling requires transporting the recycled old asphalt mixture to the mixing plant, processing it into finished materials through screening, crushing, mixing and other processes, and then transporting it to the site for paving and compaction. This process puts forward differentiated requirements for the performance and specifications of the cold recycling machine. For most construction units, leasing a cold recycling machine is the optimal solution that balances cost-effectiveness and construction needs. However, many practitioners tend to confuse the equipment compatibility standards between the factory office and on-site cold recycling when leasing, resulting in improper equipment selection and substandard quality of finished materials. Today, we will focus on the factory run cold regeneration process, popularize the core points of cold regeneration machine leasing, and answer the key question of "how to lease a cold regeneration machine that is suitable for factory run cold regeneration", helping everyone avoid leasing misconceptions and achieve efficient and high-quality construction.

　　要明確，廠辦冷再生的工藝特性，決定了其對冷再生機(jī)的核心需求與就地冷再生有明顯區(qū)別。所謂廠辦冷再生，是冷再生工藝的重要分支，核心流程是將路面翻修產(chǎn)生的舊瀝青混合料回收后，運(yùn)輸攪拌廠，經(jīng)前期篩分、破碎處理，分類為不同規(guī)格的再生料，再通過冷再生機(jī)加入泡沫瀝青、乳化瀝青等添加劑，充分拌合加工成成品再生料，終轉(zhuǎn)運(yùn)施工現(xiàn)場完成攤鋪、壓實(shí)。其核心優(yōu)勢在于成品料級配更穩(wěn)定，再生料添加比例可達(dá)60%-80%，甚實(shí)現(xiàn)100%回收利用，同時(shí)因?yàn)r青加工溫度低，兼具減排、施工成本低、項(xiàng)目投入小等特點(diǎn)，目前廣泛應(yīng)用于公路中底層施工，面層應(yīng)用仍處于逐步完善階段。

　　Firstly, it should be clarified that the process characteristics of factory run cold regeneration determine its core requirements for cold regeneration machines, which differ significantly from on-site cold regeneration. The so-called factory office cold recycling is an important branch of the cold recycling process. The core process is to recycle the old asphalt mixture generated from pavement renovation, transport it to a professional mixing plant, screen and crush it in the early stage, classify it into different specifications of recycled materials, add foam asphalt, emulsified asphalt and other additives through the cold recycling machine, fully mix and process it into finished recycled materials, and finally transport it to the construction site for paving and compaction. Its core advantage lies in the more stable grading of finished materials, the addition ratio of recycled materials can reach 60% -80%, and even achieve 100% recycling. At the same time, due to the low processing temperature of asphalt, it has the characteristics of energy conservation and emission reduction, low construction cost, and small project investment. Currently, it is widely used in the construction of the middle and bottom layers of highways, and the application of the surface layer is still in the stage of gradual improvement.

　　適配廠辦冷再生的冷再生機(jī)，核心要求集中在篩分破碎精度、拌合均勻度與設(shè)備適配性上，這也是租賃時(shí)需關(guān)注的核心要點(diǎn)。廠辦冷再生的核心環(huán)節(jié)是舊料的篩分、破碎與成品料拌合，舊料需經(jīng)處理后分類為2-3種規(guī)格，才能保證后續(xù)拌合的級配穩(wěn)定性，因此租賃的冷再生機(jī)需配備篩分破碎裝置，確保能將舊料精準(zhǔn)分級，去除雜質(zhì)、結(jié)塊，避免因篩分不徹底導(dǎo)致成品料級配失衡，影響路面強(qiáng)度與使用壽命。

　　The core requirements for a cold regeneration machine that adapts to factory cold regeneration are focused on screening and crushing accuracy, mixing uniformity, and equipment adaptability, which are also key points to pay attention to when leasing. The core process of factory run cold recycling is the screening, crushing, and mixing of old materials with finished products. The old materials need to be classified into 2-3 specifications after processing to ensure the stability of the subsequent mixing gradation. Therefore, the leased cold recycling plant needs to be equipped with an efficient screening and crushing device to ensure accurate grading of the old materials, remove impurities and clumps, and avoid the imbalance of the finished material gradation caused by incomplete screening, which affects the strength and service life of the road surface.

　　租賃適配廠辦冷再生的冷再生機(jī)，步要明確設(shè)備類型與施工規(guī)模的匹配度。廠辦冷再生設(shè)備分為移動式與固定式兩種，租賃時(shí)需結(jié)合項(xiàng)目體量、舊料處理量靈活選擇：移動式冷再生機(jī)具備靈活便捷的優(yōu)勢，可根據(jù)攪拌廠場地大小、舊料回收進(jìn)度靈活調(diào)整作業(yè)位置，適合中小型項(xiàng)目或舊料分散回收的場景；固定式冷再生機(jī)處理效率高、篩分拌合精度高，適合大型項(xiàng)目或舊料集中、處理量較大的場景，能實(shí)現(xiàn)規(guī)?；?、標(biāo)準(zhǔn)化生產(chǎn)成品料。此外，需根據(jù)舊料處理量，選擇適配產(chǎn)能的冷再生機(jī)，避免設(shè)備產(chǎn)能不足影響施工進(jìn)度，或產(chǎn)能過剩造成租賃成本浪費(fèi)。

　　The first step in leasing a cold regeneration machine that is suitable for factory office cold regeneration is to clarify the matching degree between equipment type and construction scale. Factory run cold recycling equipment is divided into two types: mobile and fixed. When renting, flexible selection should be made based on project size and old material processing capacity. Mobile cold recycling machines have the advantage of flexibility and convenience, and can adjust their operating positions flexibly according to the size of the mixing plant site and the progress of old material recycling. They are suitable for small and medium-sized projects or scenes of scattered old material recycling; The fixed cold recycling machine has high processing efficiency and high screening and mixing accuracy, suitable for large-scale projects or scenarios with concentrated old materials and large processing volumes, and can achieve large-scale and standardized production of finished materials. In addition, it is necessary to select a cold recycling machine that is suitable for the capacity of the old material processing, in order to avoid the impact of insufficient equipment capacity on construction progress or the waste of leasing costs caused by overcapacity.

　　其次，要關(guān)注冷再生機(jī)的拌合性能與添加劑適配性。廠辦冷再生需將再生料與泡沫瀝青、乳化瀝青等添加劑充分拌合，拌合均勻度直接決定成品料的性能，因此需優(yōu)先租賃配備雙臥軸強(qiáng)制式拌合裝置的冷再生機(jī)，確保再生料與添加劑混合均勻細(xì)膩，無結(jié)塊、離析等問題。同時(shí)，需確認(rèn)冷再生機(jī)支持泡沫瀝青、乳化瀝青等常用添加劑的添加，且能精準(zhǔn)控制添加比例，契合廠辦冷再生“高再生料添加比例”的需求，確保成品料質(zhì)量達(dá)標(biāo)。

　　Secondly, it is important to focus on the mixing performance and additive compatibility of the cold recycling machine. The plant office cold recycling needs to fully mix the recycled materials with foam asphalt, emulsified asphalt and other additives. The mixing uniformity directly determines the performance of the finished materials. Therefore, it is necessary to give priority to renting the cold recycling machine equipped with a double horizontal shaft forced mixing device to ensure that the recycled materials and additives are evenly and finely mixed without caking, segregation and other problems. At the same time, it needs to be confirmed that the cold recycling machine supports the addition of common additives such as foam asphalt and emulsified asphalt, and can accurately control the proportion of addition, which meets the needs of the factory office for cold recycling of "high proportion of recycled materials" to ensure that the quality of finished materials meets the standard.

　　再者，租賃時(shí)需結(jié)合廠辦冷再生的施工注意事項(xiàng)，關(guān)注設(shè)備的配套服務(wù)與細(xì)節(jié)適配。廠辦冷再生生產(chǎn)中，回收舊料的篩分破碎是基礎(chǔ)，租賃的冷再生機(jī)需具備穩(wěn)定的篩分破碎性能，避免因設(shè)備故障導(dǎo)致舊料處理停滯；同時(shí)，成品料運(yùn)輸距離需控制在60km以內(nèi)，貼合乳化瀝青4-8小時(shí)的破乳時(shí)間要求，租賃商家若能提供配套的運(yùn)輸建議或協(xié)同服務(wù)，可進(jìn)一步提升施工效率。此外，的租賃商家會提供設(shè)備維護(hù)、技術(shù)指導(dǎo)等售后保障，比如安排技術(shù)人員調(diào)試設(shè)備，指導(dǎo)操作人員規(guī)范操作，避免因操作不當(dāng)導(dǎo)致設(shè)備故障或成品料質(zhì)量問題。

　　Furthermore, when renting, it is necessary to consider the construction precautions for cold recycling in the factory office, and pay attention to the matching services and details of the equipment. In the cold recycling production of the factory, the screening and crushing of recycled old materials is the foundation. The leased cold recycling machine needs to have stable screening and crushing performance to avoid the stagnation of old material processing due to equipment failure; At the same time, the transportation distance of finished materials should be controlled within 60km, which meets the requirement of 4-8 hours for emulsion breaking time of emulsified asphalt. If leasing merchants can provide supporting transportation suggestions or collaborative services, the construction efficiency can be further improved. In addition, high-quality rental merchants will provide after-sales support such as equipment maintenance and technical guidance, such as arranging professional technicians to debug equipment, guiding operators to operate in a standardized manner, and avoiding equipment failures or quality problems of finished materials caused by improper operation.

　　結(jié)合目前市場應(yīng)用現(xiàn)狀，廠辦冷再生因成品料級配穩(wěn)定、成本可控，應(yīng)用場景逐步擴(kuò)大，而選對冷再生機(jī)租賃服務(wù)，能進(jìn)一步放大其工藝優(yōu)勢。相較于購置適配廠辦冷再生的冷再生機(jī)，租賃可節(jié)省80%以上的設(shè)備投入，尤其適合短期施工項(xiàng)目、資金有限的施工單位，同時(shí)可根據(jù)項(xiàng)目進(jìn)度靈活調(diào)整租賃期限，避免設(shè)備閑置。此外，的租賃商家會根據(jù)項(xiàng)目規(guī)模、舊料處理需求，為施工單位適配的設(shè)備類型與規(guī)格，甚提供個(gè)性化租賃方案，幫助施工單位降低成本、提升效率。

　　Based on the current market application status, factory run cold recycling has gradually expanded its application scenarios due to the stable grading and controllable cost of finished materials. Choosing the right cold recycling machine rental service can further enhance its technological advantages. Compared to purchasing cold regeneration machines that are compatible with factory run cold regeneration, leasing can save more than 80% of equipment investment, especially suitable for short-term construction projects and construction units with limited funds. At the same time, the leasing period can be flexibly adjusted according to project progress to avoid equipment idle. In addition, high-quality leasing merchants will recommend suitable equipment types and specifications for construction units based on project scale and old material processing needs, and even provide personalized leasing solutions to help construction units reduce costs and improve efficiency.

　　這里給施工從業(yè)者提個(gè)小提醒，租賃適配廠辦冷再生的冷再生機(jī)，核心是“匹配工藝、精準(zhǔn)選型、關(guān)注細(xì)節(jié)”。切勿盲目租賃就地冷再生設(shè)備勉強(qiáng)用于廠辦施工，也不要忽視設(shè)備的篩分破碎精度、拌合性能與售后保障，優(yōu)先選擇口碑好、資質(zhì)齊全的租賃商家，現(xiàn)場查驗(yàn)設(shè)備性能與參數(shù)，明確租賃條款，確保設(shè)備能適配廠辦冷再生的全流程需求。同時(shí)，施工過程中需規(guī)范操作，配合舊料篩分破碎、添加劑精準(zhǔn)添加等環(huán)節(jié)，充分發(fā)揮冷再生機(jī)的性能優(yōu)勢，確保成品料級配穩(wěn)定，實(shí)現(xiàn)舊料回收利用與施工質(zhì)量提升的雙重目標(biāo)。

　　Here is a small reminder for construction practitioners. Renting a cold recycling machine that is compatible with the factory's cold recycling system requires "matching the process, precise selection, and attention to details". Do not blindly lease on-site cold recycling equipment for forced use in factory construction, nor ignore the screening and crushing accuracy, mixing performance, and after-sales guarantee of the equipment. Prioritize choosing rental merchants with good reputation and complete qualifications, inspect the equipment performance and parameters on site, clarify the leasing terms, and ensure that the equipment can meet the full process requirements of factory cold recycling. At the same time, it is necessary to standardize the operation during the construction process, cooperate with the screening and crushing of old materials, precise addition of additives and other links, fully utilize the performance advantages of cold recycling, ensure stable grading of finished materials, and achieve the dual goals of efficient recycling of old materials and improvement of construction quality.

　　總結(jié)來說，廠辦冷再生的成品料質(zhì)量與施工效率，核心取決于冷再生機(jī)的適配性，而租賃作為選擇，關(guān)鍵在于精準(zhǔn)匹配設(shè)備類型、關(guān)注核心性能、完善售后保障。選對適配的冷再生機(jī)，不僅能確保舊料篩分破碎徹底、成品料拌合均勻，還能提升施工效率、降低施工成本，契合資源循環(huán)利用與減排的方針政策。隨著廠辦冷再生技術(shù)的逐步完善，選擇靠譜的冷再生機(jī)租賃服務(wù)，將成為施工單位提升核心競爭力、實(shí)現(xiàn)降本增效的重要支撐。

　　In summary, the quality of finished materials and construction efficiency for factory run cold recycling depend on the adaptability of the cold recycling machine, while leasing, as the optimal choice, is crucial in accurately matching equipment types, focusing on core performance, and improving after-sales support. Choosing the right suitable cold recycling machine can not only ensure thorough screening and crushing of old materials, uniform mixing of finished materials, but also improve construction efficiency and reduce construction costs, in line with the national policy of resource recycling and energy conservation and emission reduction. With the gradual improvement of cold recycling technology in factory offices, choosing reliable leasing services for cold recycling machines will become an important support for construction units to enhance their core competitiveness and achieve cost reduction and efficiency improvement.
