The traditional groove process is divided into horizontal groove and longitudinal groove. Horizontal groove is conducive to longitudinal braking, but the lateral anti-slip is weak; longitudinal groove groove conducive to horizontal anti-skid, but the vertical brake is weak. Horizontal, vertical groove at the same time the higher cost.
Since the rotary milling machine can be used for cement concrete pavement treatment of a new type of machinery, the texture of its treatment, but also with vertical, horizontal and other multi-directional good anti-skid performance. Based on the structural characteristics and performance characteristics of the rotary milling machine, this paper discusses the possibility and effect of anti - skid noise reduction in cement concrete pavement. Urge experts to give guidance.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery
The milling path of the linear milling machine is linear and is machined by a linear milling machine to form many straight grooves. When the milling cutter is in contact with the ground, the direction of its impact or impact fluctuates along the circumference of the revolution and travel, and its trajectory is in the form of a plurality of planar spiral dashed lines. Since the rotary milling machine has a horizontal adjustment device, the milling plane can be formed by turning the circular plane parallel to the surface to be treated, and the inlet mechanism can be used to control the depth of the milling machine on the ground.
Each drum of the rotary milling machine is provided with 4 rows or 6 rows or 8 rows of milling inserts along the circumference. Each row of milling blades is composed of a plurality of milling cutter blades, Diameter less than the milling cutter (piece) mounting hole diameter of 7 ~ 15mm, string between the milling cutter blade is also equipped with gasket, milling the spacing between the blade according to different needs to set the gasket control. This structure allows the milling blade to be in a free state in the radial direction (7 to 15 mm) and in the axial direction (0.1 to 0.3 mm) in the arbor. So the string in the knife on the milling cutter, along the drum drum circumference at a certain speed to touch the ground, the ground to form a shock or impact force. When the impact or impact momentum is sufficient to overcome the strength of the surface of the treated cement concrete, the impacted or impacted cement concrete is removed, and when the momentum of the impact or impact force is insufficient to overcome the surface strength to be treated, the milling blade Was bounced, and this rally was controlled in the gap between the bore of the milling insert and the diameter of the arbor.
