subject: Features And Process Flow Of Weathering Sand [print this page] Weathered sand is an intermediate product of the surface rock weathering process, anddurability than the average poor soil material, physical and mechanical properties compared to the instability. The characteristics of the weathered sand particles with the angular intensity is weak, the size distribution of in homogeneities larger and contains a quantity of fine soil particles.
The physical characteristics of the weathered sand
The physical and mechanical properties of weathered sand and cement stability of weathered sand a variety of road performance of the pilot study results show that the cement stabilized weathered sand with good mechanical properties, and application prospect.
Weathered sand is mostly the granitic gneiss and diorite gneiss, highly weathered gneiss by the explosion dug loose and transit, it becomes loose weathered gravel or stone-Mo. Weathered sand has a strong water resistance, can be used as building sand. Consolidation of weathered sand also can be used as the permeable material or semi-permeable material. Can achieve good results with a flat rolling or compaction of the ram plate weathered sand, the rolling of the weathered sand can be added to water (such as Yahekou), can also add water (such as Pine Ridge, Bailianhe Dahuofang, etc.). From resource-rich weathered sand declaimer, low cost, turning waste into wealth, technology is reasonable and technically feasible. Weathered sand compression by weak mineral composition (especially mica) content influence is great, when the pressure in the 1 to 3 kg / cm 2, the compression coefficient is roughly the range of from 0.005 to 0.05 cm 2 / kg with the initial porosity ratio decreases sharply reduced when the major vertical load of 2 to 3 kg / cm 2, has changed little. Increase of mica content, not only weathered sand the amount of compression increases, but also difficult to compaction; saturation of the compacted weathered sand soaking may be swelling. It should not be used too much of the weathering of mica content of sand built far from the dam.
Weathered sand approach is weathered sand mining to crushing, thinning under the action of the exciting force, crushing density of weathered sand; then be washed, wash away the sand in the small amount of powder and impurities, reduce sand mud rate, clean sand, gravel content, and finally get to meet the architectural requirements of the sand material. From resource-rich weathered sand declaimer, low cost, turning waste into wealth, technology is reasonable and technically feasible.
Weathered sand production line mainly by the jaw crusher, sand making machine, roller screen, sand washing machine and belt conveyor.
