[quangongzi]

Reasonable purchase roller, not only related to the quality of construction projects and construction progress, but also conducive to play equipment, supporting capacity and reduce project cost, so that users get the most benefits. At present, the domestic market roller brands, many models, the price difference is large, uneven quality of products, giving users more choice, but also increased the difficulty. In order to reduce the investment risk, to obtain higher returns, should be combined with the construction needs of a reasonable procurement, in many ways to weigh the pros and cons of the product.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery

Reasonable Selection of Roller Type
In accordance with the principle of mechanical roller is usually divided into static and vibration-type two. Static roller can be divided into two rounds of light wheel roller, roller wheel and three wheel tire roller; vibratory roller can be divided into tire-driven single-drum vibratory roller, dual-wheel drive roller and bump-type vibratory roller.
According to soil structure selection
In general, tire-driven single drum vibratory roller suitable for rolling non-viscous materials such as gravel, gravel, sand and gravel mixture, sand soil; double drum vibratory roller is suitable for compaction of asphalt concrete, sand and gravel mixture And dry rigid concrete, is a high-grade highways, municipal roads, parking and industrial sites and other general construction equipment. And the two-wheeled roller static roller is suitable for rolling fine soil particles, sand, sand and gravel mixture and asphalt concrete materials; three-wheeled roller static roller because of its heavier weight, and the road with "iron" effect, can make the roadbed And asphalt pavement smooth and therefore suitable for the final compaction of a variety of viscous, non-viscous materials. Bumped vibratory rollers can produce extremely high line loads during vibration compaction, not only for rolling non-cohesive soils, but also for rolling tack Soil, is the highway, mining roads and large dams and other projects in the ideal foundation for compaction equipment.
