The exhibition
Ceramic Liner: plain ceramic liner, weldable ceramic liner, trapezoidal ceramic liner, ceramic cylinder, ceramic block, alumina wear liner, rubber backed ceramic panel, ceramic composite panel, mining wear liner and so on.
Ceramic Grinding Media: 92% alumina media, 95% alumina media, 99% alumina media, ZTA 370 grinding media, ZTA380 grinding media, ZTA 450 grinding media, ZTA 470 grinding media, silicate zirconia grinding media, yttria stablized zirconia grinding media, ceria stablized zirconia grinding media and so on.
Alumina oxide balls have proven capabilities with superior wear performance in corrosive environments and high temperature conditions.
The material resists oxidation and is tolerant to high moisture environments, salt solutions, and many chemicals.
Typical applications include pumps, valves and flow meters.
Technical Parameters
Ceramic standard balls are made of wear-resistant ceramic material and are available in a variety of diameters:
4mm 5mm 6mm 8mm 9.52mm 10mm 12mm
14mm 15mm 17mm 20mm 25mm 25.4mm 30mm
35mm 38.1mm 41.275mm 50.8mm 60mm 100mm
Smooth spherical roundness 0.12~2μm, matte spherical roundness 0.25~5μm
Feature description
There are various forms of supply, and the commonly used styles are as follows:
A standard ball, bare ball without holes
A standard ball with holes
A standard ball + club (can be customized)
Instructions for use
Ceramic standard balls are available in two types: light surface and matte surface. Smooth balls are suitable for probe calibration of three-coordinate measuring machines.
In order to accurately calculate the coordinates of the contact point, the half/diameter of the stylus gemstone ball must be obtained through probe calibration.
Matt ball is suitable for non-contact optical measurement of three-coordinate and imager.
The diameter of standard balls is between 4mm and 100mm.
