Some key points about roller compactors in Luoyang

【文章概要】According to a roller manufacturer in Luoyang, rollers have relatively broad requirements for the moisture content of fill materials, with tolerances of 3%–5% in both the vertical and horizontal directions. Once the soil has been graded and leveled, the advantages of using rollers become even more pronounced, particularly in arid or semi-arid regions where soil moisture levels are very low—often approaching 0%–1%. Impact rollers require only a minimal amount of water to be sprayed on the surface to be compacted, significantly reducing the need for additional water and lowering construction costs.

Luoyang road roller Manufacturers contend that rollers have relatively broad requirements for the moisture content of fill materials, with tolerances of 3% to 5% in both the vertical and horizontal directions. In practice, these advantages become particularly pronounced after the soil has been graded and leveled, especially in arid or semi-arid regions where moisture levels are very low—often approaching 0% to 1%. Impact rollers require only a minimal amount of water to be sprayed on the surface prior to compaction, significantly reducing the need for additional water and lowering construction costs.

According to the Luoyang roller manufacturer, the roller can compact fill material directly on existing pavement (old road surfaces), with each layer exceeding 0.6–1 meter in thickness, thereby replacing excavation and layered compaction and boosting construction efficiency. The small drum achieves a rolling‑and‑compacting area four times that of conventional rollers per hour and an eightfold increase in compacted volume. Meanwhile, the large‑drum unit maximizes its speed and productivity during rolling operations.

According to a roller manufacturer in Luoyang, tire rollers also feature adjustable ballast and variable tire inflation pressure, making them particularly well-suited for compacting a wide range of materials. Owing to these characteristics, tire rollers are widely used for compaction of base courses, sub‑base courses, embankments, and asphalt surface layers. In particular, when compacting asphalt pavements, the flexible compaction capability of tire rollers is unmatched by other equipment, rendering them the primary machinery for re‑compacting asphalt mixtures and an ideal choice for constructing high‑grade highways, airports, ports, embankments, and industrial construction sites.

According to the Luoyang roller manufacturer, the impact wheel consists of two non-circular impact wheels and a spindle assembly, serving as the primary working component of the impact roller. The impact wheels are mounted on either side of the frame and connected via the spindle assembly. Driven by the traction system, the impact wheels roll forward, with their center of gravity alternately rising and falling, thereby delivering a combined kinetic and potential energy impact to the ground and achieving rapid compaction.

According to the Luoyang road roller manufacturer, due to the operating characteristics of the impact wheel, when it strikes the ground and performs work, it also imparts lateral and longitudinal impacts to the frame. To address this, the impact wheel axle assembly is connected to the central structure via a rocker arm, enabling both vertical motion of the wheel’s center of gravity and non-uniform velocity, thereby achieving coordinated movement with the frame. The rocker arm, cushioning rubber blocks, and hydraulic buffer cylinders interact to provide shock absorption, preventing the impact wheel from imposing excessive forces on the towing device.

The Luoyang roller manufacturer states that the frame is a box‑type structure welded from steel plates, with a traction mechanism mounted at the front, a rocker arm connected in the middle, and a lifting hydraulic cylinder at the rear. The entire frame is supported by four solid rubber tires, enabling short‑distance transport and on‑site relocation. Since the impact roller itself is not self‑propelled, it requires tractor traction to operate. To prevent horizontal impact forces—resulting from changes in the impact wheel’s kinetic energy—from damaging the tractor and to ensure the operator enjoys a comfortable working environment, the traction system incorporates a specially designed bidirectional buffer device.
