Unlike traditional hammer mills or impact crushers that use high-speed striking (which causes massive mechanical wear and sheds iron manganese dust into the mineral), the Hydraulic Double Roller Crusher operates at a very low rotational speed (low RPM).

It crushes potassium feldspar using controlled static hydraulic pressure, squeezing the material cleanly along its natural crystal cleavage planes. Combined with our customized non-magnetic, high-alloy roller shells, frictional wear is minimized to near-zero levels, completely safeguarding the whiteness and chemical purity required for premium ceramic glazes and glass batches.
