Asphalt Granulator Unit


Used to break bituminous samples for bulk density tests. The stainless steel mortar container of the machine is charged with approx kg of a roughly separated bituminous sample and its cover is closed.Then the machine is started and the exchangeable granulating tool is milling the sample within short time to grain sizes suitable for the test. The milling time can be preselected. Typically 1 to 3 minutes are sufficient. The mortar container can be tilted forward manually for discharging the sample into a suitable container (recommended 95-2044). The noise emission of the machine is reduced by an additional hinged cover with safety switch. Supplied including timer, Start/Stop button and switch for manual reverse mode. 


Timer: 0  to 60min

Dimensions: approx. 410 x 550 x 835mm

Weight: approx/ 60 kg

Electrical Specs: 230V, 60Hz, 1.5 kW
