　　Previously, we have introduced shallow and full body on-site cold recycling construction. Today, we will focus on sharing the factory cold recycling knowledge in the cold recycling process, while also focusing on the leasing points of the core equipment - cold recycling machine, to help you accurately avoid pitfalls and efficiently carry out construction. Factory run cold recycling is also an important type of cold recycling process, and the biggest difference from on-site cold recycling is that the recycled old asphalt mixture is transported to the mixing plant for re mixing and processing into finished materials, and then transported to the construction site for paving. Compared to on-site cold recycling, factory run cold recycling has become an important choice for highway maintenance and renovation projects due to its advantages such as more stable grading of finished materials, high utilization rate of recycled materials, and controllable construction costs. This unique processing flow puts forward differentiated requirements for the performance and specifications of the cold regeneration machine, which is significantly different from equipment that is suitable for on-site cold regeneration. 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.

　　首先要明确，厂办冷再生的工艺特性，决定了其对冷再生机的核心需求与就地冷再生有明显区别。所谓厂办冷再生，是冷再生工艺的重要分支，核心流程是将路面翻修产生的旧沥青混合料回收后，运输至专业搅拌厂，经前期筛分、破碎处理，分类为不同规格的再生料，再通过冷再生机加入泡沫沥青、乳化沥青等添加剂，充分拌合加工成成品再生料，最终转运至施工现场完成摊铺、压实。其核心优势在于成品料级配更稳定，再生料添加比例可达60%-80%，甚至实现100%回收利用，同时因沥青加工温度低，兼具节能减排、施工成本低、项目投入小等特点，目前广泛应用于公路中底层施工，面层应用仍处于逐步完善阶段。

　　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.

　　适配厂办冷再生的冷再生机，核心要求集中在筛分破碎精度、拌合均匀度与设备适配性上，这也是租赁时需重点关注的核心要点。厂办冷再生的核心环节是旧料的筛分、破碎与成品料拌合，旧料需经处理后分类为2-3种规格，才能保证后续拌合的级配稳定性，因此租赁的冷再生机需配备高效筛分破碎装置，确保能将旧料精准分级，去除杂质、结块，避免因筛分不彻底导致成品料级配失衡，影响路面强度与使用寿命。

　　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.

　　租赁适配厂办冷再生的冷再生机，第一步要明确设备类型与施工规模的匹配度。厂办冷再生设备分为移动式与固定式两种，租赁时需结合项目体量、旧料处理量灵活选择：移动式冷再生机具备灵活便捷的优势，可根据搅拌厂场地大小、旧料回收进度灵活调整作业位置，适合中小型项目或旧料分散回收的场景；固定式冷再生机处理效率高、筛分拌合精度高，适合大型项目或旧料集中、处理量较大的场景，能实现规模化、标准化生产成品料。此外，需根据旧料处理量，选择适配产能的冷再生机，避免设备产能不足影响施工进度，或产能过剩造成租赁成本浪费。

　　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，要重点关注冷再生机的拌合性能与添加剂适配性。厂办冷再生需将再生料与泡沫沥青、乳化沥青等添加剂充分拌合，拌合均匀度直接决定成品料的性能，因此需优先租赁配备双卧轴强制式拌合装置的冷再生机，确保再生料与添加剂混合均匀细腻，无结块、离析等问题。同时，需确认冷再生机支持泡沫沥青、乳化沥青等常用添加剂的添加，且能精准控制添加比例，契合厂办冷再生“高再生料添加比例”的需求，确保成品料质量达标。

　　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, priority should be given 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，租赁时需结合厂办冷再生的施工注意事项，关注设备的配套服务与细节适配。厂办冷再生生产中，回收旧料的筛分破碎是基础，租赁的冷再生机需具备稳定的筛分破碎性能，避免因设备故障导致旧料处理停滞；同时，成品料运输距离需控制在60km以内，贴合乳化沥青4-8小时的破乳时间要求，租赁商家若能提供配套的运输建议或协同服务，可进一步提升施工效率。此外，优质的租赁商家会提供设备维护、技术指导等售后保障，比如安排专业技术人员调试设备，指导操作人员规范操作，避免因操作不当导致设备故障或成品料质量问题。

　　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.

　　结合目前市场应用现状，厂办冷再生因成品料级配稳定、成本可控，应用场景逐步扩大，而选对冷再生机租赁服务，能进一步放大其工艺优势。相较于购置适配厂办冷再生的冷再生机，租赁可节省80%以上的设备投入，尤其适合短期施工项目、资金有限的施工单位，同时可根据项目进度灵活调整租赁期限，避免设备闲置。此外，优质的租赁商家会根据项目规模、旧料处理需求，为施工单位推荐适配的设备类型与规格，甚至提供个性化租赁方案，帮助施工单位降低成本、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.

　　这里给施工从业者提个小提醒，租赁适配厂办冷再生的冷再生机，核心是“匹配工艺、精准选型、关注细节”。切勿盲目租赁就地冷再生设备勉强用于厂办施工，也不要忽视设备的筛分破碎精度、拌合性能与售后保障，优先选择口碑好、资质齐全的租赁商家，现场查验设备性能与参数，明确租赁条款，确保设备能适配厂办冷再生的全流程需求。同时，施工过程中需规范操作，配合旧料筛分破碎、添加剂精准添加等环节，充分发挥冷再生机的性能优势，确保成品料级配稳定，实现旧料高效回收利用与施工质量提升的双重目标。

　　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.

　　总结来说，厂办冷再生的成品料质量与施工效率，核心取决于冷再生机的适配性，而租赁作为最优选择，关键在于精准匹配设备类型、关注核心性能、完善售后保障。选对适配的冷再生机，不仅能确保旧料筛分破碎彻底、成品料拌合均匀，还能提升施工效率、降低施工成本，契合国家资源循环利用与节能减排的方针政策。随着厂办冷再生技术的逐步完善，选择靠谱的冷再生机租赁服务，将成为施工单位提升核心竞争力、实现降本增效的重要支撑。

　　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.
