The main engine that planer of road surface mill is machinery of construction of conserve of bitumen road surface is planted one of, basically use at the bitumen Tong facing such as road of highway, town to keep clear of embrace bag, oily billow, reticulation, rut to wait. With the old lay up that milling of planer of road surface mill damages, again laid new facing is a kind most modern conserve method of economy, as a result of its work efficiency deepness of simple, milling controls craft of tall, construction easily, operate property of convenient and agile, motor-driven the old stuff of good, milling can reclaim directly use etc, use extensively at town consequently in municipal road and freeway conserve project.

One, classification and applied circumstance

According to milling form, mill planer can be divided for cold mill type and hot mill type two kinds. Power of configuration of cold mill type is greater, cutting tool wears away faster, cutting expects granuality is even, can install sprinkler gush water, use extensive, the product already became series; Because hot mill type increased to add heat up device and make a structure relatively complex, use at road surface second birth to work commonly.

Press the direction of rotation of milling rotor, can divide for suitable mill type He Nixi type two kinds. The wheel direction of rotation when the direction of rotation of rotor and mill planer walk is suitable mill type identically, it is the type that go against mill conversely.

According to structural characteristic, cent is round of type and crawler two kinds. Annulus type maneuverability is good, turn field is convenient, special agree with medium or small road surface works; Crawler is the large mill planer of above of milling width 2000mm more,

Old stuff reclaims device, apply to project of second birth of large area road surface.

Press the position of milling rotor, can divide mix for type of rear overhang type, horizontally pivoted hung as coaxial as rear type. Rear overhang type namely milling rotor is pensile the rear at rear; Type of horizontally pivoted hung namely milling rotor is between around bridge; Rear coaxial type namely milling rotor and rear coaxial are decorated.

According to the exercise width of milling rotor, can divide for small-sized, medium-sized and large wait for 3 kinds. The milling width of small-sized mill planer is 300~800mm, the transmission way of milling rotor uses mechanical more, the road surface that basically applies to construction area to be less than 100M2 maintains a project; The milling width of medium-sized mill planer is 1000~2000mm, the transmission way of milling rotor is fluid pressure type more; The milling width of large mill planer is in 2000mm above, cooperate to use with other machinery commonly, form the whole set of equipment of rehabilitate of road surface second birth, way of transmission of its milling rotor also is fluid pressure type more. According to transmission way cent is mechanical and fluid pressure type two kinds. Mechanical works reliable, maintenance efficiency of convenient, drive tall, production cost is low, but its structure complex, operation efficiency of not light, exercise inferior, traction is lesser, apply to the task of conserve of miniature road surface with simpler cutting; Structure of fluid pressure type compact, operation light, motor-driven agile, traction is bigger, but it is more difficult to make this tall, maintenance, apply to the task of conserve of medium, large-scale road surface with more difficult cutting.
