摘要： The present application provides an efficient treatment method and apparatus for multiphase steel slag. According to the present application, the treatment apparatus for multiphase steel slag comprises a steel slag feeding apparatus and a drum for treating steel slag, and the steel slag feeding apparatus comprises a feeding chute; the treatment apparatus for multiphase steel slag further comprises a storage compartment disposed between the feeding chute and the drum; the storage compartment is an open cylinder, and has one end forming a working fit with the lower open end of the feeding chute and the other end being fixedly connected to and coaxial with the treatment cavity of the drum. By means of the storage compartment obliquely placed between the front of the drum and the feeding chute and used for buffering and transition, there is no need to use a slag raking apparatus, and safe technological treatment of various steel slag by a drum is implemented.

摘要： An integrated drying process and device for dry granulated slag and sludge. The process comprises the following steps: 1) slag ball mixing and soaking: high-temperature slag and steel balls are fully mixed and exchange heat therebetween, the high-temperature slag is cooled because the heat thereof is quickly absorbed by the steel balls and is crushed to form granular slag, and the temperature of the steel balls rises because the steel balls absorb the heat of the high-temperature slag; and 2) sludge drying: the high-temperature steel balls are conveyed to a sludge drying device to be mixed with injected sludge, the sludge is dried, the steel balls are separated from the sludge when the water content of the sludge reaches a set value, and the steel balls and the sludge are separately discharged. In the present invention, high-temperature slag waste heat is used for heating steel balls, and sludge is dried by means of the heated steel balls, thus achieving the cooperative treatment of slag cooling, granulation and sludge drying, solving two difficult problems of slag cooling and sludge drying, and greatly increasing the waste heat recycling rate of high-temperature slag.
