By the gravity of the machinery itself, it is suitable for various compaction operations, causing deformation and compaction of the compacted layer. It is also divided into two categories: steel wheel type and tire type.
The roller structure includes a smooth roller, a groove roller, and a sheep foot roller. Smooth rolling is widely used and mainly used for compaction of road surface layers. Adopting mechanical or hydraulic transmission, it can concentrate force to compact protruding parts, with high compaction flatness, suitable for asphalt pavement compaction operations.
There are various types of wheels arranged according to their axles, including single axle single wheel, double axle double wheel, double axle three wheel, and three axle three wheel. Powered by an internal combustion engine, using mechanical or hydraulic transmission. General front wheel steering, good maneuverability, rear wheel drive. To improve steering and rolling performance, it is advisable to use an articulated steering structure and all wheel drive. The front wheel frame and frame are hinged to reduce the body swing caused by uneven road surfaces. The rear wheel and frame are rigidly connected. Using hydraulic control and hydraulic cylinders to control steering. Both the front and rear grinding wheels are equipped with scraper plates to remove the adhesive on the grinding wheels. It is also equipped with a water spraying system, which is used to spray water on the roller to prevent adhesion of the asphalt mixture when compacting the asphalt pavement. To increase the force, iron, sand, water, etc. can also be added to the grinding wheel to increase the weight.
The towed vibration roller can effectively compact various types of soil and rock fills, and is suitable for construction projects such as modern highways, airports, embankment fills, seaports, embankments, railways, mines, etc
A roller with many protrusions installed on the drum. Due to the shape of the convex block resembling a sheep foot, it is called a sheep foot roller, also known as a sheep foot roller. The shapes of convex blocks include sheep feet, cylinders, and square columns. The roller shaft is supported on the traction frame bearing to expand its range of use. The drum can be filled with water, sand, or iron sand to increase the rolling weight. A comb shaped scraper is installed below the frame before and after the drum to remove mud blocks stuck between the protrusions.
The tractor type sheep foot roller is towed by a tractor. Self propelled sheep foot roller, also known as tamping roller. Sheep foot roller has a high unit pressure, making the filling material uniform and has a compaction effect. It has a high degree of compaction, especially for hard clay, and is suitable for compacting cohesive soil and gravel layers. Especially for hard clay, convex blocks have the functions of stirring, kneading, and tamping, making the filling uniform. The upper and lower layers are well bonded to avoid layering. Widely used for compaction of roadbed, cushion layer, and embankment projects.
The self-propelled sheep foot roller can also be equipped with an excitation device in the drum to make a vibrating compaction roller, which uses the excitation force to increase the compaction effect. The drum can be filled with water, sand, or iron sand to increase the compaction weight. Expand the scope of use.
The main technical parameters of a sheep foot mill are machine weight and unit pressure. Due to the shape of the convex block resembling a sheep's foot, it is called a sheep's foot roller
Compaction of foundations for highways, railways, dams, airports, buildings, factories, and residential buildings.
Compaction of the storage site for cement plant waste, ash, coal and other loose materials.
Compaction of soil and rock with a wide water content.
Compaction of rocks, clay, and expansive soil.
Flame retardant compaction of open-pit coal seams.
