1200 Grit Aluminum Oxide Manufacturers USA

Here 50 = sieve screen is used as the sieve for white fused alumina checking the basic grain of F54 abrasive according to national standards, see Table 1-2. Another example is that the mesh size of the 35 mesh is 500um, separated by 4 particle size numbers, and the mesh size of the 60 mesh is 250 μm. National standards stipulate that the white fused aluminum oxide 60 grit particle size of fine powders is F230 ~ F1200.

If the photoelectric sedimentation instrument is used for testing, R = 2t ~ 1.4142 is the common ratio. If the brown fused aluminum oxide factory sedimentation tube particle size is used for testing, R is from 1.173 to 1.305 → 1.197. In the P series, the national standard stipulates that the common ratio of the abrasive grain size number P12 ~ P220 is mainly Rmg = 2 + ~ 1.1892, and Ras is the vice. National standards stipulate that the brown aluminium oxide manufacturer particle size of fine powder is P240 ~ P2500.


If it is measured by sedimentation tube white aluminum oxide particle size analyzer, R is from 1.120- → 1.589 → 1.196. Each particle size abrasive product is not a single size particle group, nor is it a particle group whose size is limited between the pore sizes of two adjacent screens, but a collection of several particle groups that span several screen sizes. Taking F36 abrasive as an example, the brown fused alumina for grinding size range of each particle group will be described.


When specifying the size range of white aluminium oxide manufacturer each size number abrasive and the mass ratio relationship of each particle group in each size number, the particles of each size number abrasive are divided into five particle groups, that is, the coarsest, coarse, basic, mixed Grains and fines. In the determination of the brown aluminum oxide blast media particle size composition, the long-term inspection screen must be regularly calibrated with "standard sand".


The elementary particle refers to the particle group between the pore size of the sieve corresponding to the white corundum particle size and the adjacent coarse No. 1 sieve: the coarse particle is a coarser particle group closest to the elementary particle; the fine particle is adjacent to the elementary particle A finer grain group; the coarsest grain is a grain group larger than the coarse grain size; the mixed grain is the white aluminum oxide 120 grit sum of the basic grain group and the adjacent finer grain group.


Abrasive particle size composition is the measurement and calculation of the white aluminum oxide 220 grit mass percentage of each particle group.  The black silicon carbide suppliers screening machine used in the screening method is a $ 200 flapping vibrating screen with a rotation speed of 290r / min, a tapping frequency of 156 beats / min, and a diameter of (200 ± 1) mm. Replace damaged screens in a timely manner. There is no determined common ratio.


The white aluminum oxide blast media manufacturing process does have a certain degree of requirements for the mixed particle group. It can improve the strength of the abrasive or change the structure of the abrasive. Studies have shown that when the basic grain content is 45% to 50%, the coarse grain content is 10% to 25%, and the finer grain group content of a single mixed grain is 25% to 35%, the brown fused alumina grit has the largest bulk density value.


In addition, the requirements of the brown aluminum oxide 70 grit grinding process on the abrasive are not intended to be a single particle group. When some of the finer particles are included in the abrasive, the processing finish of the workpiece can be improved. China's national standards stipulate the method for determining the aluminium oxide grit 24 mesh particle size composition of abrasives, using the sieving method for F4 to F220 and the sedimentation tube analysis method for F230 to F1200.
