Classified by grinding wheel
The structure of the grinding wheel includes light milling, groove grinding and sheep's foot grinding. Smooth rolling is the most widely used, mainly used for pavement surface compaction. Using mechanical or hydraulic transmission, it can concentrate on compacting the protruding part, and the compaction flatness is high, which is suitable for asphalt pavement compaction operation.
Classified by axle
According to the wheel axle, there are single axle single wheel, double axle double wheel, double axle three wheel and three axle three wheels and so on. It is powered by an internal combustion engine and adopts mechanical transmission or hydraulic transmission. Generally front-wheel steering, good maneuverability, rear-wheel drive. In order to improve the steering and rolling performance, it is advisable to adopt an articulated steering structure and all-wheel drive. The front wheel frame and frame are hinged to reduce fuselage wobble when the road surface is uneven. The rear wheels and frame are rigidly connected. It is hydraulically operated and steered with hydraulic cylinders. The front and rear rollers are equipped with scrapers to remove the binders on the rollers. It is also equipped with a water spraying system to spray water on the roller to prevent the asphalt mixture from sticking when compacting the asphalt pavement. In order to increase the force, iron, sand, water, etc. can also be added to the grinding wheel to increase the pressure.
