Through an internal study, the company realized that more than 20% of tires are thrown away because they are flat or damaged, resulting in a lot of waste that is difficult to process. By creating an airless tire, Michelin is diverting this problem and should, in principle, extend the life of these tires.

To improve the grinding of cassiteritepolymetallic sulfide ores, this paper studied the effect of six kinds of grinding aids. We found that these six kinds of grinding aids can change the grinding effect, but only PAM can make the eligible size fraction increase …

The law of grinding process is similar to our previous study of the waste glass powder : the downward trend of large size particles is more obvious than that of small size particles with the increase of grinding time, indicating that the coarse particles have a higher grinding efficiency than fine particles during the grinding process.

Grinding uses a grinding or sanding wheel to remove a thin layer of rubber from the entire tread surface. Grooving is a third form of mechanical tire preparation that uses a special heated tool to cut additional grooves in a tire's tread. Mechanical preparation of tire treads is an inexact science because of the variable nature of dirt tracks.

A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.

Ganjian et al. have classified the discarded tire rubber into chipped, crumb and ground rubber. (1) Shredded or chipped rubber that replaces coarse aggregates: Tires are shredded in two stages.At the end of the first stage, the rubber pieces would be shredded to 300–430 mm length and 100–230 mm width.In the second stage of shredding, the length would be reduced to 100–150 mm, and then ...

A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process. In this study ...
