Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
Use with moderate pressure keep the wheel moving to avoid digging into deep in one spot. The flap wheel will cut slower but leave a finer finish, and is a little easier to use, so save that for the last few passes, to do the final sizing. Cast iron comes in different alloys, and some are hard to grind, other are easy, but all can be ground.
One of the economic factors of grinding is the wear of the grinding is dependent upon the material used in its manufacture, method of manufacture, size of media, diameter of mill, speed of mill, pulp level maintained in the mill, rate of feed, density of pulp maintained, shape of the liner surface, nature of the feed, and the problem of corrosion.

The cast iron simply won''t bend. Instead, it breaks, it shatters under stress. This is why when one is removing cast iron, the best solution is often to shatter it into smaller pieces. Ok, so what does this mean in terms of true cutting with a sharp blade, instead of abrasive cutting with a grinding wheel?
