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. Colleges, testing labs, tender contractors and distributors can obtain the machine through Science Lab Supplies, whose dispatch point is Ambala, India.
Specifications
Drum, drive, counter and option data for the abrasion machine are tabulated individually. In short, a rolled steel drum 711 mm in inside diameter and 508 mm long is turned at 31–33 rpm by an electric motor through a speed reducer, and an automatic counter can be preset to revolutions or 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 on samples reduced with the Sample Splitters (Riffle Boxes).
- Diploma civil engineering: quality testing of road and concrete aggregate.
- Comparing aggregate sources in project work, alongside specific gravity from the Coarse Aggregate Density Test Set.
- TVET materials-testing courses: supervised operation of a counter-controlled test machine.
The drum turns with the abrasive charge inside and is noisy in operation. Keep hands and loose clothing clear while it runs, and operate the machine only under supervision; the optional safety cabinets add 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. Mention the test standard and any cabinet upgrade on the contact page, or place the machine in the enquiry cart with other aggregate tests; the lab tender page covers tendered purchases.
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, driven by an electric motor through a speed reducer.
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. Either can be added to the quotation, as the machine itself is supplied without a cabinet.
Who supplies the Los Angeles Abrasion Machine?
The machine is supplied by Science Lab Supplies from Ambala, India. Universities, polytechnics and testing laboratories are quoted directly, while tender contractors and distributors are given matching quotations to pass on to the institutions they represent.
