Feldspar Ore Grinding. The Rod Mill is standard for grinding feldspar ore, producing a granular product with a minimum of slime and fine size material. Grinding is always done to minus 20 mesh on account of market requirements. Feldspar this coarse will float very nicely and if liberation is obtained at this size no further grinding is necessary.
