The invention relates to a compact hot sintering mineral transferring system and process. The system comprises a guide device, a conversion groove, a material transferring tank, a transferring tank trailer and a lifting device; the guide device is arranged at the position of a chute of a sintering machine discharging opening, an outlet of the guide device is connected with the conversion groove, an unloading valve is arranged at the bottom of the conversion groove, and a loading station of the material transferring tank is arranged below the unloading valve; the material transferring tank is arranged on the transferring tank trailer, and the transferring tank trailer moves back and forth between the loading station and a lifting station of the material transferring tank; and the lifting device moves back and forth between the lifting station of the material transferring tank and a vertical furnace. The system is small in floor space, material transferring is rapid and convenient, the rapid transferring requirement of hot sintering mineral in the high temperature state can be met, and conditions are created for developing vertical furnace type hot sintering mineral sensible heat recovery and using processes.
