Ceramic bearing balls can weigh up to 40% less than steel ones, depending on size and material. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate 20% to 40% faster than conventional bearings. This means that the outer race groove exerts less force inward against the ball as the bearing spins. This reduction in force reduces the friction and rolling

· Erosion rate of Cr 2 AlC is linear with erosion time under 110 m/s normal impact.. The erosion induced crack network is about 10 µm thick and 100 nm in crack width. • Oxidation induced healing of erosion damage in Cr 2 AlC restores material integrity.. The erosion rate of Cr 2 AlC is retarded after healing treatment at 1200 °C in air.. The concept of reducing erosive wear by oxidative

Wear rates are calculated results reflecting wear mass loss, volume loss or linear dimension change under unit applied normal force and/or unit sliding distance. Wear rate can be expressed in many different ways. Examples are listed in Table 1. Wear resistance. Wear resistance is a term frequently used to describe the antiwear properties of a
learn moreBall mill Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical
learn moreWork hardening Wikipedia
Work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic hardening may be desirable, undesirable, or inconsequential, depending on the context. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. Many nonbrittle metals with a reasonably high melting

There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution. Based on our world wide experience, AIAE can help

Reduce wear from vibration. Equipment exposed to static vibration risks false brinelling, (erosion of the surfaces within the ball and raceway contacts), which can lead to spalling and premature failure. Lighter weight ceramic balls and dissimilar materials reduce the risk of false brinelling damage considerably. Lower operating temperatures. Because ceramic balls are only 40% as dense as
