Safe to grind aluminum or not A discussion started in but continuing through especially when grinding steel and similar metals after it has been clogged The expanding soft metal can apparently force the composite particles of the wheel apart in an explosive manner This post is a little late but these things stay on line After grinding the chalk particles are sifted over vibrating screens to separate the finer particl The particles are then mixed with water extruded through a die of the proper size and cut to the proper length Finally the chalk is cured in an oven for four days
