Production method of brown corundum and the advantages of fine crushing and shaping


The production method of brown corundum, after arc melting, cooling, waste separation, crushing, wind separation, screening, etc., is characterized by:
a. Raw materials are aluminum ash waste;
b. Wash the aluminum ash waste with water until the PH value of the washing water is 6-7.
c. The washed aluminum ash waste is dried at a temperature of 200 to 800 ° C to a moisture content of less than 1%.
d. In the arc smelting process, dry alumina ash is added with 0.5 to 1% of brown alumina corundum seed crystals and mixed, and then smelted at a temperature of 1,900 to 2,500 ° C.
1. The impact crusher is optimized to be designed as a low-speed, multi-crushing-chamber impact crusher. Its line speed is reduced by 20% -25% compared with the general impact crusher, and high production capacity is achieved with low energy consumption.
Second, the impact crusher has three levels of crushing and shaping functions, so the crushing ratio is large, the product shape is cubic, can be selectively crushed, unique impact tooth plate, keyless connection. Etc.
3. The reasonable plate hammer structure of the impact crusher has the advantages of fast loading and unloading, multiple position changes, etc., which can greatly shorten the time of plate change. .
Fourth, the impact crusher with new manufacturing technology, successfully developed a high wear resistance, high toughness of chrome, molybdenum, vanadium alloy materials, to solve the problem of hard material crushability. Greatly improved the service life of the hammer.
