Centrifugal Extractor Motorized operated

Image
 Centrifugal Extractor Motorized operated: The Centrifuge Extractors are utilized for assurance of bitumen rate in hot blended clearing blends and asphalt tests. The blend is included with a dissolvable and broke up bitumen is evacuated by divergent activity. The Extractors are available in two versions, Hand operated and motorized electrically driven. The Centrifuge Extractor motorized version is provided with a variable speed control device and a handbrake to stop rotation when switched off. The electric motor is of 0.25 HP capacity coupled to a geared assembly. Suitable for operation on 230 Volts, 50 Hz, AC single phase. Specifications of Centrifugal Extractor: Centrifuge Extractor, Electrical Operation, Capacity 1500g, with a Dimmer stat for speed control from 2,400 to 3,600 rpm. Suitable for operation on 230 V, 50 Hz, Single Phase, A.C. supply. Used for the determination of bitumen percentage in bituminous mixtures. It consists of a removable, precision machined al...

Marshal Stability Test Apparatus

Marshal Stability Test Apparatus: For the most part, The Marshall stability test is appropriate to hot blend plans utilizing bitumen and Aggregates up to the greatest size of 25mm. In this strategy, the protection from plastic twisting of a round and hollow example of the bituminous blend is estimated when the same is stacked at the outskirts at 5 cm for each min. This test method is utilized as a part of planning and assessing bituminous clearing blends. The test strategy is widely utilized as a part of routine test programs for clearing occupations.  There are two noteworthy highlights of the Marshall strategy for outlining blends to be specific, a) thickness – voids examination b) Stability – stream tests. The Marshall soundness of blend is characterized as the greatest load conveyed by a compacted example at a standard test temperature of 60ºC. The stream esteem is misshapening the Marshall test example experiences amid the stacking up to the greatest load, 0.25 mm uni...
