    Dorry Abrasion Testing Machine

    Dorry Abrasion Testing Machine that we provide is used for determining the resistance of aggregate to wear by abrasion. If there is an inadequate abrasion resistance of road-surfacing aggregates that it means an early loss of the texture depth, which is basically required for maintaining the high-speed skidding resistance. Dorry Abrasion Testing Machine features a disc rotating about a shaft that is connected to a reduction gearbox fixed to a motor. That disc rotates at 28-30 R.P.M. It features two conical hoppers, two holes for specimens and two containers with weights. It is ideal to be operated on 220 volts, 50 cycles, and A.C. supply.
