ABSTRACT:
A pavement grinder for grinding and grooving pavement surfaces has a grinding carriage with a rotating arbor supporting a number of radial blades. The arbor is directly coupled to shafts of hydraulic motors with an adaptor between the arbor shaft and the motor shaft. Debris from grinding is removed by a removal system using suction. Suction bars extend behind and to the sides of the arbor and a shroud is positioned in front of the arbor. The debris is suctioned to a separation tank which directs the debris downward away from the vacuum force. Gravity and the downward momentum of the debris is greater than the vacuum force, so the debris is separated from the air flow. The debris is directed to the bottom of the tank and enters a slurry which is pumped for disposal.
