| description | The invention provides a lump ore pretreatment system based on a shaft tube type rotary kiln. The lump ore pretreatment system comprises the rotary kiln and a shaft tube type drying and screening device. And the shaft tube type drying and screening device is arranged in the rotary kiln. Lump ore to be treated is conveyed to a rotary kiln, and a thermal medium is introduced into the rotary kiln. The lump ore to be treated is dried and screened in the rotary kiln at the same time, and dried large-particle lump ore is obtained. In order to solve the problem that natural lump ore is high in moisture, the invention provides a pretreatment method for drying by directly adopting a rotary kiln; the lump ore is dried and screened in the shaft tube type rotary kiln, moisture of the lump ore is removed, and a heat source needed by drying preferably comes from hot waste gas of a steel mill. The pretreatment system and method provided by the invention are simple, practical and reliable, and are beneficial to engineering p |
