Rotary Drum Abrasion Tester

The Rotary Drum Abrasion Tester is a DIN-type instrument that measures abrasion volume loss from cylindrical rubber and elastomer specimens moving across an abrasive-covered rotating drum. It is used for tires, footwear, hoses, conveyor products, floor materials, and compound development where abrasion resistance must be compared under ISO 4649 or GB/T 9867 test conditions.

Product Introduction

Product Overview

Core Advantages

Non-Repeating Wear Path across the Drum

The 150 ± 0.2 mm diameter drum rotates at 40 ± 1 r/min while the specimen holder moves laterally 4.2 ± 0.06 mm per drum revolution. The shifting contact line prevents the specimen from repeatedly following the same groove, producing a more representative abrasion path.

Selectable Load and Grinding Distance

The standard specimen load is 2.5 N, with additional weights for 5 N, 7.5 N, or 10 N, and the grinding distance can be set to 20 m or 40 m. High-wear and low-wear compounds can be tested at a condition that produces a measurable loss without unnecessary over-abrasion.

Automatic Endpoint and Debris Control

The drive, sample carriage, automatic stop, and dust collection unit operate as one system. Abrasion debris is removed from the contact area while the machine ends the test at the selected travel distance, limiting contamination of the wear track.

Customization Capabilities

Specimen-holder dimensions and abrasive-paper mounting can be adapted to an existing laboratory procedure or fixture drawing. Dust collection and safety enclosure can be integrated around the bench layout. Counter interface and power supply can be matched to the installation.

Quality Control

Drum diameter, rotational speed, surface runout, and carriage travel per revolution are measured after assembly. The loading weights, holder alignment, abrasive-paper clamping, dust extraction, and automatic stop are then checked under operating load. A reference specimen run is completed before the final inspection.
