AS PER BS: 812 The machine is used to determine the resistance of aggregate to wear by abrasion. Inadequate abrasion resistance of road-surfacing aggregates means an early loss of the texture depth required to maintain high-speed skidding resistance.
Salient Features

Specification :It consists of a disc rotating about a shaft connected to a reduction gear box coupled to a motor. The disc rotates at 28-30 r.p.m. Under the rotating disc is a tray with an outlet to facilitate the removal of sand. Two conical hoppers are mounted on a bracket fixed to the circular tray. An arrangement is made for start and stop the flow of sand. Two holes are provided for mounting two specimens simultaneously. Two containers with weights are supplied to keep the specimens pressed against the rotating disc. Suitable for operation on 220 volts, 50 cycles, A.C. supply.

Engineered For Accuracy and Safety

Equipped with a manual calibration system-using reference blocks-and an analog reading display, this machine ensures precise abrasion measurements, with 1% reading accuracy and immediate response. The enclosed metal guard enhances operation safety, safeguarding users during each complete 360 revolution test stroke.

Robust Construction for Extended Service Life

Crafted from powder-coated, anti-rust mild steel, the machine stands up to rigorous laboratory use. Features like replaceable hardened steel discs and a counter-weighted arm system help minimize wear and streamline specimen changes, while its free-standing, space-efficient design suits most laboratory environments.

FAQ's of Dorry Abrasion Testing Machine:

Q: How does the Dorry Abrasion Testing Machine measure aggregate abrasion resistance?

A: The machine uses a rotating 200 mm abrasive disc and standard abrasive powder to abrade a specimen mounted on a counter-weighted arm. After a set number of revolutions (360), the loss in specimen material is measured manually, providing a quantitative assessment of abrasion resistance as per IS 2386 (Part IV) standards.

Q: What is the process for calibrating the machine before testing?

A: Calibration is performed manually using the provided reference blocks to ensure accuracy. Users should follow the included guidelines to adjust the mechanism and confirm the analog display is correctly set before beginning a test cycle.

Q: When should the wearing disc be replaced?

A: It is advisable to inspect the hardened steel disc regularly for significant wear or scoring. Replace the disc whenever you notice loss of surface integrity to maintain measurement accuracy and prolong the machine's service life.

Q: Where can the Dorry Abrasion Testing Machine be used?

A: This machine is optimized for laboratory environments in research, quality control, construction material analysis, and educational institutes. Its free-standing, compact design makes it suitable for bench-top or floor use wherever aggregate abrasion testing is required.

Q: What are the benefits of using the enclosed sheet metal guard during testing?

A: The protective enclosure ensures safety by containing debris and reducing operator exposure to moving parts and abrasive powder. It also helps in maintaining a cleaner testing area and mitigates noise, keeping operational sound below 70 dB.

Q: How many specimens can be tested per cycle, and what is the standard size?

A: The machine accommodates one specimen per test cycle, with the standard recommended size being approximately 50mm x 50mm x 25mm. This ensures compliance with IS 2386 (Part IV) and repeatability across testing sessions.
