Dorry Abrasion Testing Machine (Product Code: SLE/CE/96) is a motor-driven rotating disc machine used to measure the abrasion resistance of stone and aggregate specimens pressed against it while sand is fed as the abrasive, in civil engineering and geology laboratories. Engineering colleges and materials labs use it to compare building stones and road aggregates, and its two hoppers and two weighted containers let two specimens run at once. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

The Dorry test grades the hardness of rock and stone by how quickly it wears when rubbed against a turning disc under a steady stream of sand. Each specimen sits in its weighted container so that it bears on the disc with a constant pressure, the hoppers are opened to feed sand, and the disc turns at 28–30 RPM for the number of revolutions the test calls for. Loss of mass or thickness after the run shows how the stone would resist foot traffic, wheels or flowing water.
Weigh specimens carefully before and after the test, keep the sand dry so it flows evenly from the hoppers, and empty the tray outlet between runs. This machine suits geology and highway-materials teaching in engineering colleges, as well as quality checks on paving and flooring stone at technical institutes.
Jain Scientific Equipments Private Limited, trading as ScienceLab, makes the Dorry Abrasion Testing Machine as its own OEM product. The disc drive, circular tray, hopper bracket and weighted containers are manufactured and assembled at the company's licensed factory at Saha, Ambala, Haryana, India.
Because buyers deal with the maker rather than a reseller, engineering colleges, laboratories, dealers and importers can take up repeat orders and questions about wear parts directly with the factory. Learn about the company on the ScienceLab profile page.

How many specimens can the Dorry Abrasion Testing Machine test at once?
The Dorry Abrasion Testing Machine has two conical sand hoppers and is supplied with two containers with weights, so two specimens can be pressed against the rotating disc in the same run. This helps laboratories compare two stones or duplicate a sample.
At what speed does the disc of the Dorry Abrasion Testing Machine rotate?
The disc of the Dorry Abrasion Testing Machine rotates at 28–30 RPM. It is driven through a shaft connected to a reduction gear box that is coupled to the motor, giving a steady, slow speed suited to abrasion testing.
How is sand fed and removed on the Dorry Abrasion Testing Machine?
On the Dorry Abrasion Testing Machine, sand is fed from two conical hoppers mounted on a bracket fixed to the circular tray, with an arrangement to start and stop the flow. Used sand collects in a tray under the disc and leaves through an outlet.
What power supply does the Dorry Abrasion Testing Machine use?
The Dorry Abrasion Testing Machine is suitable for operation on a 220 V, 50 cycles, AC supply. Buyers with a different mains supply should mention it in their enquiry so that we can discuss the requirement before quoting.
Who manufactures the Dorry Abrasion Testing Machine?
The Dorry Abrasion Testing Machine is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Quotations and replacement-part questions are handled by the manufacturer directly.
Is abrasive sand supplied with the Dorry Abrasion Testing Machine?
