LM17704

 

LM17704 : CENTRIFUGAL   EXTRACTOR  (HAND  OPERATED)

Conforms to A.S.T.M.D : 2172

The centrifugal extractor designed for 1.5 kgs.of sample mix. It is a safe  and  portable  unit          for  accurate  determination  of  bitumen percentage,  character  and         gradation  of  aggregates  in  field operations. The centrifuge is a cast aluminium rotor bowl, mounted on a  vertical shaft and  enclosed inside  a leak tight housing. The rotor is bowl shaped and can be removed for weight determination. The gears operate in an oil bath, with splash lubrication. Supplied without filter discs and solvent.
