Aluminum Oxide 40 Grit Manufacturers Pakistan

Now the method of 70 grit aluminum oxide blast media producing magnesium hydride by sea water and lime is used. Chesny has made news on the production mode of industrial hydrogenated magnesium in 1936, but the mode of complete and absorption in quotation has not changed greatly. Therefore, there is no residual calcium carbonate and 46 grit aluminum oxide impurities in the coarse-grained part due to thermal disintegration.

The ways to get high quality magnesium hydride are: Take out the impurities in raw limestone; Remove the 180 grit aluminum oxide impurities and carbonic acid in seawater; Improve the deposition and purification of magnesium hydride. The quicklime, which is fired in the Beckenbach shaft kiln, is matured in a self turning slaker to form lime milk. However, the 1200 grit aluminum oxide quality of this kind of lime milk has a very great influence on the quality of magnesium hydride.


The first way to remove CO2 from seawater is alkali method, i.e. adding lime milk as calcium carbonate. The white fused alumina second is acid method, that is, adding acid as the carbonate gas to remove. The advantage of alkaline method is that when seawater passes through calcium carbonate deposition tank, impurities such as SiO2 and Al2O3 can be reduced simultaneously, and the 100 grit aluminum oxide media content of CO2 can be reduced to less than 10mg-1.


The fine grit aluminum oxide magnesium hydride produced by sea water lime method is paddle liquid, with a small particle radius of 0.1 μ M. the existing problems are the concentration, sedimentation, salt removal and purification in the thickener. For this reason, the radius of the secondary 80 grit aluminum oxide blasting media particles is 2-3 μ m through the seed cycle of magnesium hydride and the addition of condensing agent. The refined lime milk is extracted by centrifugal separator.


According to the quality of white aluminum oxide, it can be divided into the first stage sintering method and the second stage sintering method. From the beginning of the development of seawater 220 grit aluminum oxide blast media industry to 1955, the direct investment sintering furnace of magnesium hydride block was carried out. In order to improve sintering property, the addition of mineralizer and high temperature sintering were discussed.


Sintering process of white corundum. The ratio of CO2 extraction by acid method is high (95%). In 1955, the way of drying and pressure forming magnesium hydride block to carry out sintering has been quoted. With the adjustment of the content of magnesium, the hydrogenated magnesium block has been light burned since 1957, and the 120 grit aluminum oxide harbor freight resultant magnesium has been pressurized and sintered to achieve high density.


The light burning Road 5 adopts time-division Herschel multi chamber baking furnace and rotary kiln; the forming machine adopts high-pressure forming machine such as ball press; the burning furnace adopts shaft kiln and rotary kiln. 80 grit aluminum oxide with 97% magnesium content was sintered at 1500-1800 ℃, and high-purity 240 grit aluminum oxide with 98% magnesium content was sintered at 1900-2100 ℃.
