Los Angeles Abrasion Machine
Product Code : LSK-CL-10594
Los Angeles Abrasion Machine (SKU LSK-CL-10594) tests how well coarse aggregate resists abrasion by tumbling a sample with an abrasive charge inside a rotating steel drum. The loss of fine material after a set number of revolutions shows whether the stone is tough enough for roads or concrete. Highway and civil engineering labs use it. Science Lab Supplies provides the machine from Ambala, India to colleges, testing labs, tender contractors and distributors.
Specifications
A rolled steel drum with an inside diameter of 711 mm and internal length of 508 mm is turned at 31–33 rpm by an electric motor through a speed reducer. An automatic counter can be preset to the required number of drum revolutions or to the total working time.

Applications and Experiments for the Los Angeles Abrasion Machine
The machine is used for the Los Angeles abrasion test, the usual measure of coarse aggregate toughness for road bases, surfacing and concrete. It is a standard item in highway engineering and concrete technology practicals for civil engineering degrees and diplomas and in materials-testing modules at technical institutes.
- B.Tech / B.E. civil engineering: Los Angeles abrasion value in the highway engineering lab.
- Diploma civil engineering: quality testing of road and concrete aggregate.
- Comparing aggregate sources for durability in project work.
- TVET materials-testing courses: supervised operation of a counter-controlled test machine.
The drum turns with a heavy steel charge and is noisy in operation. Keep the door closed and hands clear while it runs, and operate the machine only under supervision; the optional safety cabinet adds a door-opening switch.
Standard Scope of Supply
The machine is supplied with its drum, motor and speed reducer, and automatic counter. The abrasive charge and safety cabinet are not included. It can be upgraded with a safety cabinet with door-opening switch, or a noise-reduction safety cabinet with door-opening switch.
Packing, MOQ and Lead Time
A quotation can be made for one machine, with or without a cabinet upgrade and abrasive charge, and it will show the packing, delivery time and price for that configuration. Other aggregate tests from this range can be added to the same quotation from one laboratory equipment supplier in India.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Contact the team via the contact page, add the machine to the enquiry cart, or use the lab tender page for tenders.
Frequently Asked Questions
Is the abrasive charge included?
No. The machine is supplied without the abrasive charge, because the charge depends on the standard you test to. Tell us the standard and it can be quoted separately.
What are the drum dimensions and speed?
The rolled steel drum has an inside diameter of 711 mm and an internal length of 508 mm, and it rotates at 31–33 rpm.
Which safety cabinet options exist?
Two upgrades are available: a safety cabinet with door-opening switch, and a noise-reduction safety cabinet with door-opening switch.
Who supplies the Los Angeles Abrasion Machine?
Science Lab Supplies supplies it from Ambala, India, quoting to universities, polytechnics, testing laboratories, tender contractors and distributors.
