Tailing slurry making device and slurry making method thereof

The invention provides a tailing slurry making device and a slurry making method thereof. The tailing slurry making device comprises a sand silo, a slurry making system arranged in the sand silo and an exhaust system communicated with the slurry making system; wherein the slurry making system comprises a slurry making pipe fixed on the inner wall of the sand silo, and a slurry making spray head assembly which is arranged on the slurry making pipe and is communicated with the slurry making pipe; the exhaust system comprises an air supply main pipe and an exhaust branch pipe; one end of the exhaust branch pipe is communicated with the air supply main pipe, and the other end of the exhaust branch pipe is communicated with the slurry making pipe; in addition, tailings to be subjected to slurrymaking are stored in the sand silo, and slurry making is achieved through high-pressure gas sprayed out of the slurry making spray head assembly. By utilizing the device and the method, the problemsof low efficiency, high co
