LMBAT1000 Bond Abrasion Tester
The Bond abrasion tester is a specialized machine that measures the abrasion index and the friability of the material
The Bond Abrasion Tester is a process and laboratory machine, which is designed to determine the abrasion index of a mineral sample to be determined in accordance with F.C. Bond's abrasion test method. The Bond Abrasion Tester utilizes an electrically driven drum and rotating abrasion paddle. The mineral sample is lifted by a mesh drum liner and dropped on to the steel paddle, which rotates in the same direction. The paddle is made to exacting standards of material and size and two square inches of this is exposed to wear. After running the test, the weight loss of the paddle is noted in grams, this represents the Abrasion Index (Ai) of the material

Bond abrasion tester working principle
A Bond Index Abrasion Test Machine is a specialized device used in the mining and mineral processing industries to measure the wear resistance (abrasiveness) of rock or mineral samples.
The test is crucial for understanding how abrasive an ore or material is, which is important for the design of grinding circuits and equipment selection.
The result of this test is known as the Bond Abrasion Index (Ai), which quantifies the abrasiveness of the material and helps in predicting the wear rate of mill liners and grinding media.
The machine is constructed from robust, high-durability materials to withstand the harsh conditions of abrasion testing. It consists of a rotating cylindrical drum and an abrasion steel paddle that creates friction against the sample.
Rotating Drum: A cylindrical drum rotates at a specified speed. The drum holds a set of metal paddles and is loaded with a specific amount of abrasive rock sample.
Abrasion Paddle: The paddle is made of steel and is mounted inside the drum. It serves as the wear surface, and its mass loss is measured to determine the abrasion index.
A sample of ore is prepared and placed in the rotating drum of the machine, along with the abrasion paddle.
The drum rotates, causing the ore sample to tumble and grind against the abrasion paddle. The friction and impact between the ore particles and the paddle result in the wearing down of the paddle.
After a fixed number of revolutions, the mass loss of the abrasion paddle is measured. The greater the mass loss, the more abrasive the ore sample is.
The Bond Abrasion Index (Ai) is then calculated based on the mass loss and other test parameters.
The ore sample is typically crushed to a standard size before testing.
The drum rotates at specifically 70rpm ensuring consistent results. The mass loss of the steel paddle is carefully measured to determine the wear rate.
Control Panel
The control panel of a Bond Index Abrasion Test Machine is designed for intuitive operation and precise control during abrasion testing.
It features a user-friendly interface with clear digital displays, allowing operators to monitor key parameters such as test duration, rotational speed, and power consumption in real time.
The control panel includes start, stop, and emergency stop buttons for enhanced safety.
This streamlined control system ensures consistent, accurate results when determining the abrasion resistance of materials, essential for quality control in industries like mining and mineral processing.
