What Are Cold Milling Planers And Rotary Drum Cutters?


Cold Milling Planers are asphalt milling devices used to remove concrete or pavement from roadways. Cold planers are sometimes referred to as roto mills, milling machines for asphalt, pavement recyclers, or pavement planers.

Pavement recycling frequently involves the use of cold planers. For use as aggregate in new pavement, pavement is crushed up and gathered. To recycle reclaimed asphalt pavement for asphalt surfaces, additional aggregate, asphalt cement, or a recycling agent must be added.


By milling, the paved surface is partially or completely removed, depending on how much thickness is removed to roughen the surface. Specialty asphalt milling machines can be used to grind features like rumble strips to add driver assistance to roadways in addition to material recycling and road resurfacing.


●      Operation of cold milling planer

Cold Planer A rotating drum with carbide cutters contacts the pavement at a predetermined depth and slope to run a cold planer. The end surface of the road is influenced by the distance between the cutters around the drum, with micro-milling having the smallest distance. As they become worn or damaged, the cutters can be taken out and replaced. Depending on the material being ground and the frequency of unintended strikes to manholes or valve access boxes, they normally last a few hours to a few days.


Most milling machines operate with an up-cut configuration, where the drum rotates in the opposite direction from how the cold planer moves.

The housing used to house the milled material encloses the drum. To cool the drum and reduce the dust being produced, water is typically applied to the drum as it spins.For different applications, Cold Milling Planers are available in a variety of sizes and configurations. They are available as engine- or hydraulic-powered attachments that are compatible with skid steers, compact track loaders, compact wheel loaders, or fully dedicated machines. Cold planers come in a variety of sizes, ranging from 12 inches to 14 feet wide, with surface roughing cutting depths of up to 12 inches. Fully dedicated planers are man-driven machines that include a grinding drum that grinds and collects the material as well as a conveyor system to remove the material from the work area.

●      Applications

Tunnel work

Road works

Municipal works 

Rotary drum cutter


A Rotary Drum Cutter is an accessory used to cut through frozen ground, rock, and concrete. Rotating drums with picks strategically placed around the outside diameter is operated by a hydraulic motor at several hundred revolutions per minute.


●      Operation of rotary drum cutter

To cut material, rotary die cutting employs specially made cylindrical dies attached to a rotating press. The press's die cutting station, which has a cutting die cylinder and a hardened anvil cylinder spinning in opposite directions along their horizontal axes, receives web, or flexible material, typically in roll or individual sheet form. The actual cutting process is carried out by the replaceable rotary cutting die, which can be either a flexible or solid die. The anvil cylinder acts as the surface on which the cutting die is used to carry out the operation. The cutting die's edge compresses the web against the anvil cylinder as it is passed through the station between the rotating die cylinder and the anvil cylinder until the edge pierces through the material. The desired cuts, slices, or holes are made as a result of this procedure. The web is then either divided into individual pieces or rewound onto a spindle.

To guarantee that the die cuts are accurately aligned, uniform, and consistent along the full length of the material, rotary die-cutting machines run the cylinders and web at the same speed. To attain even better precision and consistency, machines can additionally use servo motors and controls. Normally, a set of gears rotates the die in time with the press's feed.



●      Applications

Rock excavation, demolition, subsurface scaling, tunnel profiling, trenching, and other uses are all possible with excavator drum cutter attachments.

At depths of up to 30 meters, excavators' drum cutter attachments can likewise be operated submerged without modification. designed to remove materials with precision and maximum efficacy. provides low noise and low vibration, which is essential while working in delicate areas. It is made up of incredibly durable spur gears that are powered by hydraulic motors with high torque in the harshest conditions with little to no possibility of failure.

Rock cutters and Rotary Drum Cutters are hydraulic excavator add-ons. designed to broaden the types of jobs excavators may perform and boost their financial return.
