AbstractAbout AuthorsReferences
An important property of moistened clay soils is their stickiness, their ability to stick to surfaces which contact with them in the process of earthwork and following transportation. Quantitative values of stickiness of excavated soils are in a wide range (from 0.5 to 50 KPa and more). It is noted that the volume of stuck rock in excavator buckets is 15–35% of their estimated capacity, discharge capacity of bunkers is reduced by 20–50%, load capacity of a dump truck is reduced by 16–22%, dump cars – by 15–20%. The use of anti-sticking plates PPFP-Astiki makes it possible to significantly reduce (up to 2 KPa) and often completely eliminate the stickiness of moistened rocks and raw materials, its impact on the discharge capacity of lifters and bunkers by 1.4–1.8 times, performance of excavator equipment by 12%, load capacity of dump trucks and dump cars by 15–18%. Simultaneously, the heavy physical work which is used, as a rule, for cleaning of stuck devices of equipment is liquidated.
