　　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.

　　首先要明確，廠辦冷再生的工藝特性，決定了其對冷再生機的核心需求與就地冷再生有明顯區別。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生的舊瀝青混合料回收后，運輸至專業攪拌廠，經前期篩分、破碎處理，分類為不同規格的再生料，再通過冷再生機加入泡沫瀝青、乳化瀝青等添加劑，充分拌合加工成成品再生料，非常終轉運至施工現場完成攤鋪、壓實。其核心優勢在于成品料級配更穩定，再生料添加比例可達60%-80%，甚至實現100%回收利用，同時因瀝青加工溫度低，兼具節能減排、施工成本低、項目投入小等特點，目前廣泛應用于公路中底層施工，面層應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，核心要求集中在篩分破碎精度、拌合均勻度與設備適配性上，這也是租賃時需核心關注的核心要點。廠辦冷再生的核心環節是舊料的篩分、破碎與成品料拌合，舊料需經處理后分類為2-3種規格，才能保證后續拌合的級配穩定性，因此租賃的冷再生機需配備出色篩分破碎裝置，確保能將舊料合理分級，去除雜質、結塊，避免因篩分不有效導致成品料級配失衡，影響路面強度與使用壽命。

　　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，第一步要明確設備類型與施工規模的匹配度。廠辦冷再生設備分為移動式與固定式兩種，租賃時需結合項目體量、舊料處理量靈活選擇：移動式冷再生機具備靈活便捷的優勢，可根據攪拌廠場地大小、舊料回收進度靈活調整作業位置，適合中小型項目或舊料分散回收的場景；固定式冷再生機處理效率高、篩分拌合精度高，適合大型項目或舊料集中、處理量較大的場景，能實現規模化、標準化生產成品料。此外，需根據舊料處理量，選擇適配產能的冷再生機，避免設備產能不足影響施工進度，或產能過剩造成租賃成本浪費。

　　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，要核心關注冷再生機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，因此需優先租賃配備雙臥軸強制式拌合裝置的冷再生機，確保再生料與添加劑混合均勻細膩，無結塊、離析等問題。同時，需確認冷再生機支持泡沫瀝青、乳化瀝青等常用添加劑的添加，且能合理控制添加比例，契合廠辦冷再生“高再生料添加比例”的需求，確保成品料質量達標。

　　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，租賃時需結合廠辦冷再生的施工注意事項，關注設備的配套服務與細節適配。廠辦冷再生生產中，回收舊料的篩分破碎是基礎，租賃的冷再生機需具備穩定的篩分破碎性能，避免因設備故障導致舊料處理停滯；同時，成品料運輸距離需控制在60km以內，貼合乳化瀝青4-8小時的破乳時間要求，租賃商家若能提供配套的運輸建議或協同服務，可進一步提升施工效率。此外，優良的租賃商家會提供設備維護、技術指導等售后保障，比如安排專業技術人員調試設備，指導操作人員規范操作，避免因操作不當導致設備故障或成品料質量問題。

　　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.

　　結合目前市場應用現狀，廠辦冷再生因成品料級配穩定、成本可控，應用場景逐步擴大，而選對冷再生機租賃服務，能進一步放大其工藝優勢。相較于購置適配廠辦冷再生的冷再生機，租賃可節省80%以上的設備投入，尤其適合短期施工項目、資金有限的施工單位，同時可根據項目進度靈活調整租賃期限，避免設備閑置。此外，優良的租賃商家會根據項目規模、舊料處理需求，為施工單位推薦適配的設備類型與規格，甚至提供個性化租賃方案，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.

　　這里給施工從業者提個小提醒，租賃適配廠辦冷再生的冷再生機，核心是“匹配工藝、合理選型、關注細節”。切勿盲目租賃就地冷再生設備勉強用于廠辦施工，也不要忽視設備的篩分破碎精度、拌合性能與售后保障，優先選擇口碑好、資質齊全的租賃商家，現場查驗設備性能與參數，明確租賃條款，確保設備能適配廠辦冷再生的全流程需求。同時，施工過程中需規范操作，配合舊料篩分破碎、添加劑合理添加等環節，更好地發揮冷再生機的性能優勢，確保成品料級配穩定，實現舊料出色回收利用與施工質量提升的雙重目標。

　　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.

　　總結來說，廠辦冷再生的成品料質量與施工效率，核心取決于冷再生機的適配性，而租賃作為非常優選擇，關鍵在于合理匹配設備類型、關注核心性能、完善售后保障。選對適配的冷再生機，不僅能確保舊料篩分破碎有效、成品料拌合均勻，還能提升施工效率、降低施工成本，契合國家資源循環利用與節能減排的方針政策。隨著廠辦冷再生技術的逐步完善，選擇靠譜的冷再生機租賃服務，將成為施工單位提升核心競爭力、實現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.
