Things You Should Know About Road Milling Drums
The road milling drums are some of the crucial components of the road milling machines. They are the parts that do all the milling of the asphalt to concrete surfaces to remove the old layers. A road milling drum is designed with a large drum that is fitted with teeth for breaking the milling surface.
But there is a lot of things that most people don’t know about these tools. That’s what we are going to discuss in the article.
The Application Of Road Milling Drums
One of the things that most people get wrong is the use of the road milling drums. These machines are not used or designed for the making of the new roads. They are only used for making repairs to concrete and asphalt pavement. Their main use in the road repairs or rebuilding is to remove the old asphalt or concrete layer.
This is a misconception people have that every road contractor must have that these machines are used in all road construction. You don’t expect to find road milling machines on-site making new roads.
The Main Tasks Of Road Milling Drums
During the road milling process, the road milling machines are deployed to remove the asphalt layer. There are three main tasks that the road milling drum is expected to achieve for a successful milling process. One of them is cutting and breaking the concrete or asphalt layer into small pieces. That is depending on the number of milling bits.
The second thing is conveying the broken down layer of the road to the area of the ejector. This is the part where the broken-down material is set for ejection from the drum. The third thing the road milling drum must do is injecting the old material onto the loading conveyor. That’s basically what they are designed for.
Sizes of Road Milling Drums
The sizes of road milling drums vary depending on the size of the machine. There is a range of sizes that falls into various categories. The main categories are the large and small road milling machines. Both categories have various sizes depending on the road milling needs.
The small road milling machines also have small road milling drums of various sizes. They are small drums of removing paints and making rubble strips. There are also small but larger than drums for repairing pavements, driveways, and so on.
