Low temperature production of wollastonite from line and .

Line granules and silica sand were ground for different periods to obtain a particle size that could completely pass the ∼70-μm sieve. Line had to be ground for an hour to get a median size (d50) of 11.57 μm, while silica sand had a median size (d50) of 12.28 μm after 2 h of grinding. By performing the grinding.
