Devel Attrition Tester
Devel Attrition Tester (Product Code: SLE/AG/04) is a twin-cylinder rotating machine used to measure how much coarse aggregate wears away by attrition in road and civil engineering laboratories. Known in many specifications as the Deval test, it suits road research labs, quarries and colleges, and its two hollow cylinders, set at an angle on one shaft, let two samples run together. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM technical educational equipment manufacturer, at its own factory in Ambala, India.

What Is the Devel Attrition Tester Used For?
A weighed, graded aggregate sample is placed in a cylinder together with the steel balls the test method calls for, and the fitting cover is secured. Because each cylinder sits at an angle to the shaft, the contents slide from end to end as well as tumbling on every revolution, so the stones grind against one another rather than simply falling. After the set number of revolutions, read from the counter, the sample is removed, sieved and reweighed, and the material lost is expressed as a percentage of the original mass.
With two cylinders on the same shaft, a class can compare two aggregates, or run a duplicate, in a single session, which makes the tester practical engineering educational equipment in India's polytechnics and colleges where lab time is limited. Before each run, check that both covers are tight and that the cylinders are loaded evenly to keep the shaft balanced.
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) behind this Devel Attrition Tester. The tester is built at the company's own licensed factory at Saha, Ambala, Haryana, India, and goes factory-direct to polytechnics, road laboratories, dealers and importers, with no trading intermediary in between. For a second set of steel balls or other parts later on, ask us and the manufacturer will respond itself. Learn more on our company profile.
Related Civil Engineering Lab Equipment
These products belong to the same aggregate durability workflow:
- Los Angeles Abrasion Testing Machine — a single-drum abrasion and impact test often specified alongside or instead of the attrition test.
- Dorry Abrasion Testing Machine — a rotating-disc test with sand fed from conical hoppers, giving another view of wear resistance.
- Riffle Sample Divider — splits the field sample into representative portions for each cylinder.
- Test Sieves — for grading the sample beforehand and sieving out the worn fines afterwards.
- Oven, 43 litre — brings samples to a dry state before the starting and final weighings.

Frequently Asked Questions
How is the Devel Attrition Tester different from the Los Angeles abrasion machine?
The Devel Attrition Tester uses two hollow cylinders set at an angle on a rotating shaft, while the Los Angeles machine uses one horizontal drum with an internal shelf. The two methods load the stone differently, so check which one your specification names.
Are the steel balls supplied with the Devel Attrition Tester?
Yes. The Devel Attrition Tester comes complete with an abrasive charge of 12 hardened steel balls of 48 mm diameter, so it is ready to run once the aggregate sample has been prepared and weighed.
Can the Devel Attrition Tester run two samples at once?
Yes. Both cylinders of the Devel Attrition Tester are mounted on the same shaft and turn together, so two samples, or a duplicate of one sample, can run in a single session, provided each cylinder is loaded as the method requires.
What power supply does the Devel Attrition Tester need?
The motor of the Devel Attrition Tester is suitable for 440 Volts, three phase, 50 cycles A.C. supply. Discuss any other supply with us through the contact page before ordering so the manufacturer can advise.
How should the Devel Attrition Tester be maintained?
Empty and brush out both cylinders of the Devel Attrition Tester after every test, keep the reduction gear lubricated, and check that the fitting covers close firmly so that no fines escape during a run.
Who manufactures the Devel Attrition Tester?
The Devel Attrition Tester is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Replacement steel balls or other parts can be requested directly from the manufacturer; just ask us.
Do you ship the Devel Attrition Tester outside India?
Yes. ScienceLab supplies the Devel Attrition Tester to laboratories in India and international markets. Include the destination and quantity with your enquiry so that packing and shipping can be quoted by the manufacturer.
