Ring and Ball Manufacturer,Supplier and Exporter in India
Product Code : EL-MLE-13264
Jlab Export is a leading Ring and Ball Manufacturer,and suppliers in India
Ring and Ball (code EL-MLE-13264) is a softening point apparatus for bitumen, built for the ring-and-ball method of ASTM D36 and IP 58-B over 30–157 °C. Two rings hold the sample discs, each loaded with a 9.5 mm hardened steel ball, in a height-adjustable brass cage inside a heated, motor-stirred glass jar. JLab makes this bitumen softening point apparatus in Ambala, India.

How the Softening Point Is Found
Bitumen has no sharp melting point; it softens gradually as it warms, so the method defines a softening point by a fixed procedure. A disc of bitumen is cast in each ring, a steel ball is centred on it by the collar, and the cage is lowered into the bath. As the stirred bath is heated at a controlled rate, the discs sag under the balls, and the softening point is the bath temperature at which the softened bitumen, carrying its ball, has dropped through the distance set by the method. Two rings give a duplicate result from a single heating.
Choosing the Bath Liquid
The bath liquid follows the expected softening point: distilled water from 30 to 80 °C, glycerin above 80 and up to 157 °C, and ethylene glycol from 30 to 110 °C. Water is not used above 80 °C in this method, which is why harder grades are tested in glycerin.
Other Bitumen and Road-Material Test Apparatus
- Motorized Ring and Ball Apparatus — electrically operated, motorised apparatus for the ring and ball softening point test.
- Penetration of Bituminous Material, Grease, Petrolatum, Waxes, Gel — penetrometer reading bitumen consistency on a 1/10 mm dial.
- Standard Tar Viscometer — measures the viscosity of cut-back bitumen and road oil.
