Abstract
To effectively solve the technical problems of crushing high-hardness Archean granulite and concrete temperature control in high-temperature environment faced in the construction of Hebei Shangyi Pumped Storage Power Station,through theoretical calculation and engineering analogy methods,the mineral composition characteristics of granulite and the thermodynamic properties of high-tempera-ture concrete were analyzed.An integrated design scheme of"three-stage crushing+stepped precooling"was proposed.The aggregate system adopts the process of"jaw coarse crushing+cone medium and fine crushing+vertical shaft sand making and shaping",and the mixing system is equipped with three-stage precooling measures of"primary air cooling+wind-cooled aggregate in the mixing plant silo+cold water mixing".The research results show that the system processing capacity reaches 580 t/h,the content of needle and flake ag-gregate is controlled below4.8%,the temperature of concrete at the outlet of the mixer is stably maintained at12～14℃,and all indica-tors are better than the design requirements.This design scheme can effectively solve the collaborative technical problems of high-hard-ness rock crushing and high-temperature temperature control,and can provide technical reference for the design of auxiliary enterprise systems of pumped storage power stations under similar geological and climatic conditions.关键词
