About Ring & Ball Apparatus
Ring & Ball Apparatus
This apparatus is used to determine Softening point of Bitumen. It is that temperature at which a sample of bituminous material loaded by a 9.5 mm diameter steel ball, drops a specified distance when heated under specified conditions.
Specification :
The apparatus consists of steel bracket with a sliding plate support. That support has two holes of 10 mm diameter on which a ring and ball guide can be kept. A central hole on this plate is for inserting thermometer. Supplied with a glass beaker approximate 600 ml, high and a hand stirrer and 2 Nos. 9.5 mm diameter steel balls. Reliable Testing for Bitumen Softening PointDesigned for the precise evaluation of softening points in bituminous materials, this Ring & Ball Apparatus ensures compliance with industry standards. Its capacity for dual sample testing streamlines laboratory workflow, while the manual control system offers simple and effective operation. Enhanced by a sturdy structure and heat-resistant components, the apparatus guarantees reliable performance in demanding construction and research settings.
User-Friendly Design with Manual PrecisionEngineered for ease-of-use, the apparatus features an integrated electric heater, energy regulator, and manual stirring device. The setup allows for efficient heating and temperature control within a range from ambient to 150C, monitored accurately with high-resolution thermometers. This practical design provides laboratories with consistent, repeatable results for the assessment and comparison of bituminous samples.
FAQs of Ring & Ball Apparatus:
Q: How is the Ring & Ball Apparatus used in the laboratory setting?
A: The apparatus is used to assess the softening point of bituminous materials. Samples are placed in brass rings, submerged in a beaker containing a heating medium, and the temperature at which steel balls pass through the softened material is recorded with precision thermometers.
Q: What is the testing process for bituminous material using this apparatus?
A: The process involves filling the brass rings with bitumen, suspending them in the provided beaker, and gradually heating with the electric heater while stirring. The temperature at which the steel balls drop through the softened bitumen indicates the materials softening point.
Q: When should the Ring & Ball Apparatus be used?
A: This apparatus should be used whenever standard laboratory tests for determining the softening point of bitumen or asphalt are required, especially in quality control, research, and road construction material evaluation.
Q: Where can the Ring & Ball Apparatus be applied?
A: The apparatus finds application in bitumen and asphalt testing laboratories, road construction quality control labs, and research facilities concerned with material properties.
Q: What are the benefits of using dual test positions?
A: Dual test positions allow two samples to be evaluated simultaneously, improving efficiency and enabling comparative analysis or duplicate testing for consistent results.
Q: How precise is the apparatus and what is its accuracy?
A: With a temperature resolution of 0.1C and overall accuracy of 0.5C, the apparatus ensures reliable, detailed measurement for laboratory and industrial purposes.
