Recommendation - The hardface used should be chosen based on the material crushed and action of the part.  With hard, readily friable material (granite, quartz, etc.) and low to moderate impact, hardface with 2834-SPL.  With softer, tougher  materials (clay, limestone, etc) or if high impact forces, hardface with 2820-SPL. 

If a manganese part is to be repaired repeatedly, applying two layers of chrome-manganese first (Postalloy 2865-FCO) can be very beneficial.  It will act as a insulator to the original base metal, in helping it keep below 500°F.
