About Ring And Ball Apparatus

Specification:

A ring and ball apparatus specification typically includes components like shouldered brass rings, 9.5mm steel balls, a ball-centering guide, a thermometer, a heat-resistant glass beaker, and a support frame with a sliding plate for placing the rings. The apparatus also requires a controlled heating unit or thermostatic hot plate capable of raising the water temperature at a specific rate, a motorized or manual stirrer, and a bottom plate positioned 25mm below the rings. The entire setup is built to measure the softening point of bituminous materials according to standards such as ASTM D36 or AASHTO T53.

Key Components

Steel Balls: Two 9.5mm diameter steel balls, typically weighing 2.5 0.05 grams each.
Brass Rings: Tapered, shouldered brass rings that hold the bitumen sample.
Ball-Centering Guides: Devices to hold the steel balls in the center of the rings.
Support Frame: A frame with a sliding plate to hold the rings and allow for the insertion of a thermometer.
Glass Beaker: A heat-resistant glass vessel, often about 8.5 cm in internal diameter and 12 cm deep, for the heating bath.
Thermometer: An ASTM or equivalent thermometer to accurately measure the bath temperature, sometimes requiring calibration.
Heater/Hot Plate: A thermostatic or electronically controlled heater to provide uniform heating to the bath, sometimes with a microprocessor and auto-tune PID controller.
Stirrer: A hand or motorized stirrer to ensure even temperature distribution throughout the bath.
Bottom Plate: A plate positioned 25mm below the rings for the balls to drop onto.

Functional Specifications

Heating Rate:

The apparatus should be able to heat the bath liquid at a uniform rate, typically 5C per minute, as specified by standards like ASTM D36 or AASHTO T53.
Ring Support:

The support frame should hold the upper surface of the rings 50mm below the surface of the bath liquid.
Digital Control:

Modern versions may feature digital controllers for precise temperature setting and monitoring, with accuracy specifications.
Power Supply:

For electrically operated models, specifications include a 230V AC, single-phase, 50Hz power supply.

Application

The ring and ball apparatus is used in the quality control of bituminous materials to determine their softening point. The softening point is the temperature at which the bitumen sample, loaded with a steel ball, drops a specified distance.
