Where does the cold regeneration rental machine mainly operate? According to the milling form, the milling machine can be divided into cold milling type and hot milling type. The cold milling configuration has large power, fast tool wear, uniform particle size of cutting materials, and can be equipped with sprinkler to spray water. It is widely used, and the products have become a series; The structure of hot milling type is more complex due to the addition of heating device. It is generally used for pavement regeneration.

按铣削转子的旋转方向，可分为顺铣式和逆铣式两种。转子的旋转方向与铣刨机行走时的车轮旋转方向相同的为顺铣式，反之则为逆铣式。

According to the rotation direction of milling rotor, it can be divided into forward milling type and reverse milling type. If the rotation direction of the rotor is the same as that of the wheel when the milling machine is running, it is forward milling, otherwise it is reverse milling.

根据结构特点，分为轮式和履带式两种。轮式机动性好、转场方便，特别适合于中小型路面作业；履带式多为铣削宽度2000mm以上的大型铣刨机，有旧材料回收装置，适用于大面积路面再生工程。按铣削转子的位置，可分为后悬式、中悬式和与后桥同轴式。后悬式即铣削转子悬挂于后桥的尾部；中悬式即铣削转子在前后桥之间；后桥同轴式即铣削转子与后桥同轴布置。

According to the structural characteristics, it can be divided into wheel type and crawler type. Wheel type has good mobility and convenient transfer, especially suitable for small and medium-sized pavement operation; The crawler type is mostly a large milling machine with a milling width of more than 2000mm, with an old material recovery device, which is suitable for large-area pavement recycling engineering. According to the position of milling rotor, it can be divided into rear suspension type, middle suspension type and coaxial type with rear axle. Rear suspension type, that is, the milling rotor is suspended at the tail of the rear axle; The middle suspension type is that the milling rotor is between the front and rear axles; The rear axle is coaxial, that is, the milling rotor is arranged coaxially with the rear axle.

根据铣削转子的作业宽度，可分为小型、中型和大型等三种。小型铣刨机的铣削宽度为300~800mm，铣削转子的传动方式多采用机械式，主要适用于施工面积小于100M2的路面维修工程；中型铣刨机的铣削宽度为1000~2000mm，铣削转子的传动方式多为液压式；大型铣刨机的铣削宽度在2000mm以上，一般与其它机械配合使用，形成路面再生修复的成套设备，其铣削转子传动方式也多为液压式。

According to the working width of milling rotor, it can be divided into small, medium and large. The milling width of the small milling machine is 300 ~ 800mm, and the transmission mode of the milling rotor is mostly mechanical, which is mainly suitable for pavement maintenance projects with a construction area of less than 100m2; The milling width of medium-sized milling machine is 1000 ~ 2000mm, and the transmission mode of milling rotor is mostly hydraulic; The milling width of large milling machine is more than 2000mm. It is generally used in conjunction with other machinery to form a complete set of equipment for pavement regeneration and repair. Its milling rotor transmission mode is also mostly hydraulic.

根据传动方式分为机械式和液压式两类。机械式工作可靠、维修方便、传动效率高、制造成本低，但其结构复杂、操作不轻便、作业效率较低、牵引力较小，适用于切削较浅的小规模路面养护作业；液压式结构紧凑、操作轻便、机动灵活、牵引力较大，但制造成本高、维修较难，适用于切削较深的中、大规模路面养护作业。

According to the transmission mode, it is divided into mechanical type and hydraulic type. The mechanical type has the advantages of reliable operation, convenient maintenance, high transmission efficiency and low manufacturing cost, but its structure is complex, the operation is not light, the operation efficiency is low and the traction force is small. It is suitable for small-scale pavement maintenance with shallow cutting; The hydraulic type is compact in structure, light in operation, flexible in mobility and large in tractive force, but it has high manufacturing cost and difficult in maintenance, so it is suitable for medium and large-scale road maintenance with deep cutting.
