Classification and application
According to the milling form, the milling machine can be divided into two types: cold milling and hot milling. The cold-milling configuration has a large power, the tool wears faster, the cutting material has a uniform particle size, and the sprinkler can be sprayed with water. The product is used in a series; the hot-milling type is complicated by the addition of the heating device, and is generally used for Road surface regeneration operations.
According to the direction of rotation of the milling rotor, it can be divided into two types: down milling and up milling. The direction of rotation of the rotor is the same as the direction of rotation of the wheel when the milling machine is running, and vice versa.
According to the structural characteristics, it is divided into two types: wheeled and crawler. Wheeled maneuverability and convenient transition, especially suitable for small and medium-sized pavement operations; crawler type is mostly large milling machine with milling width of 2000mm or more.
There is an old material recycling device for large-area road surface regeneration projects.
According to the position of the milling rotor, it can be divided into a rear suspension type, a medium suspension type and a coaxial type with the rear axle. The rear suspension type milling rotor is suspended from the tail of the rear axle; the middle suspension type milling rotor is between the front and rear bridges; the rear axle coaxial type milling rotor is coaxially arranged with the rear axle.
According to the working width of the milling rotor, it can be divided into three types: small, medium and large. The milling width of the small milling machine is 300~800mm. The transmission mode of the milling rotor is mostly mechanical, which is mainly suitable for the road maintenance project with the construction area less than 100M2; the milling width of the medium milling machine is 1000~2000mm, the transmission of the milling rotor Most of the methods are hydraulic; the milling width of large milling machines is more than 2000mm, which is generally used together with other machinery to form a complete set of equipment for road surface regeneration and repair. The milling rotor is also mostly hydraulic.
According to the transmission mode, it is divided into two types: mechanical and hydraulic. Mechanical work is reliable, easy to maintain, high transmission efficiency, low manufacturing cost, but its structure is complex, operation is not light, work efficiency is low, traction is small, suitable for small-scale road maintenance work with shallow cutting; hydraulic compact structure The utility model has the advantages of light operation, flexible maneuverability and large traction force, but high manufacturing cost and difficult maintenance, and is suitable for medium and large-scale road maintenance work with deep cutting.
