Low centrifugal force applied to the construction of asphalt compactor, and the high centrifugal force applied to granular subbase construction materials. Air filtration system features a two cyclone filters and calculated for each condition of the line pressure roller. DD-110 conversion work is quite simple, quick, visual material properties, thickness, and some other indicators compaction reasonable choice (see Tables 1 and 2) professional production of rollers, which has a wide range of applications. Vibratory roller line pressure calculation: unit line pressure gauge and a stone strength required line pressure roller table soft medium hard stone nature extremely hard stone name limestone vibration roller, sandstone limestone, sandstone, fine-grained granite coarse-grained granite basalt ultimate strength 300 ~ 600 ~ 400 ~ 1000 1000 2000 2000 Rollers Pictures | Sanming roller | Shandong Heavy Jin Jin provided by Shandong Heavy Machinery Co., Ltd.
