摘要
The feasibilities of ultrafine fvollastonits prnvder have been analysed based on joint considerations of satisfying product size re-quiremet, presenting the needlelike wollastonite structure, maintaining an easy operation, stable performance and simplified flowsheet, etc. Opti-mum operating conditions have been established through, systematic reseach-es on the bases of product requirements. Modern analytical technique such as light-transmission particle sizing and scanning electron spectroscopy have been used to determine the size and morphology of the product. It is found that the meedelelike structure can be preserved even dawn to the ul-trafine range by using the toiver mill. The torver mill is easy to operate, has stable performances, and can be used in open-circuit to produce re-quired products without needing for a classifier.
