Grinding wheel raw material zirconium corundum zirconium 40 grain size sand 36 mesh 46 mesh

  Zirconium corundum is made of alumina and fused zirconia with high purity
It is smelted at high temperature of 2250 ℃ and formed by special processing technology and Bamako ball milling
It has high quality, incomparable hardness and compact structure
The crystal presents a special dendritic eutectic structure
Zircon corundum can be divided into ZA25 zircon corundum (zro225%) and ZA40 corundum (ZrO2 40%) according to the content of ZrO2

 
 
Zirconium corundum is distinguished from ordinary corundum and silicon carbide by its superior self sharpening, toughness and wear resistance
When used for making grinding wheel, the service life and sharpness of grinding wheel can be significantly improved
When used for grinding and cutting workpieces with high hardness, the wear resistance is particularly obvious
It is mainly used to produce heavy-duty grinding wheel, resin grinding wheel, cutting blade, wear-resistant products, high-grade grinding tools, etc
it is suitable for the grinding of steel parts, iron castings, heat-resistant steel, titanium alloy, nickel alloy, aluminum alloy, tungsten titanium alloy and other materials, with higher grinding force than ordinary corundum products

 
 
Characteristics of zirconium corundum:
 
 
1
  Zirconium corundum has high toughness, about 13-15 times that of brown corundum

 
 
2
  The crystal size of zirconium corundum is very small (the ordinary quality of our factory is 18-20um, and the high quality is 10-12um), which is one twentieth of that of ordinary corundum
The smaller crystal size can continuously produce a small sharp grinding surface during grinding, so the service life is very long

 
 
3
  Zirconium corundum has a high stacking density (1
9-2
45g/cm3), while ordinary corundum, such as white corundum and brown corundum, has a stacking density of 1
55-1
95g/cm3
Therefore, zirconium corundum is suitable for the production of high-speed grinding wheel, heavy-duty grinding wheel, cutting blade and other grinding tools
 
 
Difference between ZA25 and ZA40:
 
 
  The alumina content of ZA25 is higher than that of ZA40, which is suitable for wear-resistant products such as wear-resistant hammers and heavy-duty grinding wheels

 
 
  ZA40 zirconium corundum is superior to ZA25 in self sharpening, hardness and toughness
It is suitable for cutting blades, track grinding, high-end resin grinding wheels, coated grinding tools, etc
