BICO DULIN ROTAREX SEPARATORS

For the determination of bitumen content and gradation of aggregates in bituminous

paving materials. Operation requires only 10 (ten) minutes. The sample is weighed, heated

slightly to start crumbling, cooled, then placed in the Rotarex bowl. Now solvent is added.

When set in motion, centrifugal action forces all liquid through the sample and out through a

filter paper gasket at the periphery of the bowl, effectively cleaning and drying the sample. The

solvent is periodically added to the sample while the bowl is in motion until it runs perfectly

clear from the drain spout. Aggregates may then be weighed and graded. Weight before and

after the extraction of bitumen determines constituent proportions.

Solvent is recovered via an aluminum catch basin and drained from a spout. The bowl

cover is held in place by a center filler screw, which is a funnel shaped piece that screws into the

power shaft head. It also serves as an inlet for additional solvent while the Rotarex is running.

All moving parts are fully enclosed and the machine is mounted on vibration absorbing

rubber cushions.

The electric motor brake, quickly stops rotation at the end of the process to eliminate

valuable lost time between tests.
