Los Angeles Abrasion Testing Machine Manufacturer,Supplier and Exporter in India

Los Angeles Abrasion Testing Machine (Product Code: SLE/AG/03) is a motor-driven rotating drum used to measure the resistance of coarse aggregate to abrasion and impact in highway and civil engineering laboratories. Road research labs, colleges and quarries run it with a charge of twelve hardened steel balls of about 48 mm, the drum turning at 30–33 rpm through a heavy reduction gear. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM engineering lab equipment manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Los Angeles Abrasion Machine Used For?

A dried, graded sample is weighed and loaded through the charging opening together with the number of steel balls your test method specifies for that grading. With the dust-tight cover closed, the drum runs for the required number of revolutions, read from the counter. On every turn the internal shelf lifts the stones and balls and drops them across the drum, combining impact with grinding. The contents are then emptied into the collection tray, the balls removed and the material sieved; the loss in mass as a percentage of the starting mass is reported as the abrasion value.

Because the test gives a single, easily compared number, the machine sits alongside other test and measurement instruments in India's highway and materials labs as a routine acceptance check for road and concrete aggregate. Keep the shelf fixings tight, check that the cover closes dust-tight before each run so fines are not lost, and inspect the balls periodically for wear.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this Los Angeles machine. It is fabricated and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to engineering colleges, highway laboratories, dealers and importers. Buying from the maker means a request for replacement steel balls or a spare shelf reaches the same people who built the machine, so simply ask us. The ScienceLab company profile has more about the business.

Related Civil Engineering Lab Equipment

Laboratories that run the Los Angeles test usually also need:

• Digital Los Angles Abrasion Testing Machine — the version with an electronic control unit and an automatic counter that stops at a preset count.
• Devel Attrition Tester — a wear test using twin inclined cylinders, for comparing results by a second method.
• Aggregate Impact Tester — measures toughness under hammer blows, completing the aggregate strength picture.
• Sample Splitter — divides the bulk stockpile sample down to a representative portion for grading.
• Test Sieves — for grading the charge before the run and sieving it afterwards.

The full range of aggregate and road material testing items is in the Civil Engineering Lab Equipment category.

Frequently Asked Questions

Is the steel ball charge included with the Los Angeles Abrasion Testing Machine?
Yes. The Los Angeles Abrasion Testing Machine comes complete with an abrasive charge of twelve hardened steel balls of approximately 48 mm diameter, plus a tray for collecting the material at the end of the test.

What electrical supply does the Los Angeles Abrasion Testing Machine need?
The Los Angeles Abrasion Testing Machine is built for a 440 V, 3 phase, 50 cycles A.C. supply. If your laboratory has a different supply, contact us before ordering so the requirement can be discussed with the manufacturer.

How are revolutions controlled on the Los Angeles Abrasion Testing Machine?
The drum of the Los Angeles Abrasion Testing Machine turns at 30–33 rpm through a heavy reduction gear, and a revolution counter fitted to the frame shows the completed turns so the operator can stop the run at the required count.

Why does the Los Angeles Abrasion Testing Machine drum have an internal shelf?
The detachable shelf runs the full inside length of the Los Angeles Abrasion Testing Machine drum. It catches the abrasive charge on each revolution, lifting and dropping it with the stones, and stops the balls from falling onto the cover.

How does this Los Angeles Abrasion Testing Machine differ from the digital model?
This Los Angeles Abrasion Testing Machine uses a revolution counter on the frame, while the Digital Los Angles Abrasion Testing Machine has an electronic control unit and an automatic counter that stops at a preset count. Choose according to how you want runs controlled.

Who manufactures the Los Angeles Abrasion Testing Machine?
The Los Angeles Abrasion Testing Machine is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, and assembled at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and spare-part enquiries go directly to the manufacturer.
