Los Angeles Abrasion Machine

Introduction

The Los Angeles Abrasion Machine, also known as the LA Abrasion Machine, is a device to measure the degradation of mineral aggregate due to abrasion, impact and grinding. The machine has a rotating steel drum with steel spheres to abrade, impact and grind the aggregate sample. The Los Angeles Abrasion Test is used as an indicator of the relative quality of different aggregate sources and to determine the durability and suitability of aggregates for construction purposes. This test is essential to ensure that materials used in road construction, concrete production and other civil engineering projects can withstand the wear and tear over time.

The Los Angeles Abrasion Machine does not come with the abrasive charge which has to be ordered separately (see accessories).

The Los Angeles Abrasion Machine does not come with the safety cabinet and can be upgraded with:

  • CE compliant safety cabinet with door opening switch

  • Noise reduction and CE compliant safety cabinet with door opening switch

Overview

The Los Angeles Abrasion Machine is a testing device to measure the degradation of mineral aggregate due to abrasion, impact and grinding. It also tests the aggregates like crushed rock and slag to determine their abrasion resistance. This rugged abrasion machine tests the aggregates like rocks and gravels for wear and tear and determines their durability and suitability for construction applications. Whether in road construction, production or other civil engineering projects, the Los Angeles Abrasion Machine is a must have for material quality and longevity, with standard gradings resulting from the test.

  • Structural steel frame with removable shelf

  • Graphical display 128x80 pixels and 6 keys membrane keyboard

  • 8 languages: Italian, English, French, Spanish, Polish, Portuguese, Romanian and Cesky

  • Double test procedure: target revolutions/drops or total working time

  • The unit can be mounted in noise reduction and CE compliant safety cabinet with door opening switch

The D0500/GZ2 Los Angeles Abrasion Machine meets the standards of ASTM C131 and AASHTO T96. The machine has a structural steel frame, balanced drum assembly and enclosed chain drive without conventional slip clutch, for positive drive. The drum is made of 1/2″ thick abrasion-resistant steel and is mounted on anti-friction bearings with sealed lubrication for smooth operation. The machine has safety cabinet and push button controls and comes with a specified number of steel spheres, typically 12, depending on the standard gradings of the aggregate material being tested. The Los Angeles Abrasion Machine measures the abrasion loss of aggregates and the test results are used to evaluate the resistance of aggregates to wear. The machine is used in the construction industry to determine the quality and longevity of materials used in road construction, concrete production and other civil engineering projects.

  • Power: 110V, 60Hz, 1ph., 740 W

  • Dimensions approx.: 1005x820x950 mm

  • Weight approx.: 350 kg

The test method of Los Angeles Abrasion Machine is to abrade the aggregate sample with steel spheres in a rotating drum. The abrasion loss is measured as percentage of the initial weight, to give a clear indication of the material durability. The test method is designed to ensure consistent and accurate testing condition and consists of the following steps:

  • Prepare the sample of aggregate: Select and weigh the aggregate sample to be tested.

  • Load the sample into the drum: Put the aggregate test samples in the drum.

  • Add steel spheres to the drum: Put the specified number of spheres in the drum.

  • Set the drum speed and test time: Set the abrasion machine to the required speed and time.

  • Start the machine and run for the set time: Start the test and let the drum rotate for the predetermined time.

  • Measure the abrasion loss: After the test weigh the remaining aggregate to calculate the abrasion loss.

Standards for D0500/GZ2, Los Angeles Abrasion Machine:

The EN 12697-17 method (Cantabro test) is for the determination of particle loss (abrasion) of asphalt mixtures and the EN 12697-43 is for the determination of resistance of bituminous mixtures or pavement to aviation fuel. Both procedures involves, among other laboratory tests, the abrasion in a Los Angeles tester conforming to EN 1097-2 without steel balls. The EN 12697-17 also prescribes a chamber or enclosure for the Los Angeles machine as the temperature shall remain constant with an uncertainty of 2°C. This is part of the broader Los Angeles abrasion which is an indicator of aggregate quality.

This can be achieved by the soundproof and safety cabinet 48-D0500/CB2 which is however necessary to comply with CE directive.

The Controls Group D0500/GZ2, Los Angeles Abrasion Machine is a high quality testing equipment to measure the resistance of coarse aggregates to abrasion. This machine follows both EN and ASTM standards to give accurate and reliable results. The Los Angeles test which this machine performs is the resistance of coarse aggregates to abrasion by a rotating steel drum and abrasive steel balls.The Los Angeles Abrasion Machine has a rolled steel drum made of heavy steel cylinder and with precise dimensions to give a consistent testing environment. It is rotated by a speed reducer driven by an electric motor with a speed range of 31 to 33 rpm. The machine also has an automatic counter that can be set to the desired number of drum revolutions or total working time.

Please note that the Los Angeles Abrasion Machine is supplied without the abrasive charge which needs to be ordered separately based on the standard you are using. The safety cabinet is not included but can be upgraded with a CE compliant cabinet with door opening switch for added safety. For those who need noise reduction, an option is available to add a noise reduction and CE compliant safety cabinet.

The Controls Group D0500/GZ2, Los Angeles Abrasion Machine has several features to ensure accurate testing and user-friendly. Its stiff welded structural steel frame gives stability and reliability, high resolution graphical display and membrane keyboard for easy operation. The machine also has language options Italian, English, French, Spanish, Polish, Portuguese, Romanian and Cesky.
