The one-piece all-ceramic grading wheel manufactured by cold
isostatic pressing can effectively avoid wear and tear and isolate
metal contamination. It can also extend the service life of the
grading wheel and reduce the number of maintenance times, thereby
saving costs and ensuring material quality.
