Mixing granulation device and method for testing fine ore sintering performance

The invention relates to the field of detection of fine ore sintering performance and in particular relates to a mixing granulation device and a mixing granulation method. The mixing granulation device for testing the fine ore sintering performance consists of two parts, namely a material mixing device and a material lifting device, wherein the material lifting device comprises a baffle, a lifting ring, a limiting rack and a hopper body; the maximum outer diameter of a funnel-shaped discharge opening of the hopper body is slightly larger than the opening inner diameter of a feeding hole; and the minimum outer diameter of the funnel-shaped discharge opening of the hopper body is slightly smaller than the opening inner diameter of the feeding hole. The mixing granulation method for testing the fine ore sintering performance comprises the following steps: stirring twice, performing mixing granulation, and finally, tilting the cylinder down to pour the mixed materials out by virtue of a swing mechanism so as to perform the performance detection and sintering test. According to the device and the method disclosed by the invention, the test facilities and labor intensity are reduced, the mixing granulation requirements under different conditions can be met by replacing a sleeve, manual operation is not needed, the parameters set during granulation are optimized, and the stability and comparability of the mixing granulation process in the sintering test can be obviously improved.
