Analysis of the current operating conditions of the alumina slag slurry pump:

In general, alumina slurry is a strong alkaline slurry that carries hard particles such as alumina. Pingguo Aluminum uses an aluminum slurry pump LC250.580 to transport ground aluminum slurry. Generally, the particle size of the aluminum ore entering the pump is less than 1mm, the slurry concentration is 409/6-459/6, and the pump flow rate is 630m h. The alkaline concentration of the slurry is 230g/L (Na2O), pH>14, and the temperature is 80-100 ℃. Aluminum ore is mainly composed of hard alumina, with a composition of W as Al: O. 609/6-659/6, Fe: O. 14-17%, SiO: 3.59/6-4.5, Mohs hardness of aluminum ore is 7. Shanxi Aluminum Industry's alumina slurry mainly contains components such as Al: O, Na: O, SiO, and trihydrate alumina. The slurry density is 1.5g/cm, the solid content reaches 409/6-60, the slurry temperature is 80-90 ℃, and the Na2O concentration is about 18-25g.
