Method for detecting the wear rate of zirconia balls under the condition of material grinding In a 1L alumina ceramic tank, 1KG of zirconia balls to be tested are charged, 150g of water, 300g of zirconium silicate (zircon sand), 2g of sodium tripolyphosphate, capped, and fixed in a fast mill. The mill was continuously ground for 5 hours, and the zirconia balls were taken out, washed, dried, and weighed. The belt wear (Rm) of the qualified zirconia balls is required to be less than 0.15%/5h, or less than 0.03%/h. 2. Method for detecting the wear rate of zirconia balls without grinding (self-grinding) grinding conditions In a volume of 1L alumina ceramic tank, 700g of zirconia balls to be tested were placed, 300g of water was added, capped, fixed on a turntable in a fast mill for 5 hours, and the zirconia balls were taken out and dried. , weighing. The wear rate (Rs) of a qualified zirconia ball is required to be less than 0.3%/5h, or less than 0.06%/h. ...

Black silicon carbide is black, and its microscopic shape is hexagonal crystal. The Mohs hardness of silicon carbide is 9.2, the microhardness is 3000--3300 kg/mm 2 , the hardness is 2670-2815 kg/mm, and the microhardness is 3300 kg per Cubic millimeters. The density is generally considered to be 3.20 g/mm 3 , and the natural bulk density of the silicon carbide abrasive is between 1.2 and 1.6 g/mm 3 and the specific gravity is 3.20 to 3.25. The number of sand grains is 12.14.16.19.20.22.24.26.30.36.46.60.80.90.10.1120120.150.180.240.280. It is mainly used for hardness alloys, titanium alloys, stainless steel, copper, aluminum, zinc, ceramics, stone, agate, Grinding and polishing of jade, fine jewelry, electronic components and other materials. Not only can you make abrasive tools and advanced refractory materials. It can also be used in other industries. ...

Glass bead for sandblasting has the features of chemical stability, high mechanical intensity. They can be blasted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity. ...

Hot Pressed Conditioning Wheels " HPCW" The HPCW Is used mostly with diameters of 24" , 25" and 30" . The two first sizes are the more popular. These wheels are hot pressed due to the extremely high density what is impossible to reach, using the conventional cold press. After pressed and cured, these wheels became extremely dense and also extremely hard. They are reinforced with strong fiberglass reinforcements that give to the wheels the capacity to operate at 80 m/s and 300lbs to 500 lbs of pressure. The Hot Pressed Conditioning Wheels with the abbreviation HPCW are largely used by the steel mills to remove cracks and imperfections on the slabs before starting the lamination process. The cracks can provoke the rupture of the steel during the lamination process and damage severally the laminator cylinder as well as the cylinder machine. It makes all the system to stop working with enormous losses on production time and money as well. ...
