MH-II type supply Los Angeles wear machine usage method

1. Before testing the MH-II type Los Angeles wear machine, it is necessary to check whether the circuit is intact (the input power must be three flames). Press the jog button to check whether the drum rotates normally (in the direction of the arrow on the drum, if the rotation direction is opposite, swap the two hot wires in the input 380V to change it). At the same time, turn on the LED Reset the display screen to zero and adjust the preset dip switch to the number of times tested. Press the start button to start working. If there are special circumstances, press the "pause" button to stop the machine. After the fault is eliminated, press the "start" button again to resume the machine. 2. Load the crushed stones and steel balls for testing into the cylinder, seal the cover, tighten the screws, and start the instrument to rotate 500 or 1000 revolutions before automatically stopping. At this time, the discharge port is in the upper middle position, which is convenient to open the sealing cover. After opening the cover, press the jog button to turn the discharge port downwards. Release the button to stop the test cylinder and take out the test piece. 3. Use a 2mm diameter circular hole sieve or a 1.7mm side length square hole sieve to sieve out the stone chips in the sample, rinse with water and leave them on the sieve. Dry and weigh the crushed stones accurately.

MH-II type supply Los Angeles abrasion machine calculation method

1. Calculate the stone wear rate to the nearest 0.1% using the following formula: Q-grinding - stone wear rate% G1- original weight of crushed stone loaded into the cylinder g G2- weight after washing and drying g 2. The average value of two tests, with an error of no more than 2%, otherwise a new test will be conducted.

MH-II Type Supply Los Angeles Wear Machine Random Accessories

1. 1 manual, 1 certificate of conformity, 2. 12 steel balls (5000g) for testing, and different preparation methods can be used according to different experimental needs (11 steel balls 4850g, 8 steel balls 3300g, 6 steel balls 2500g). 3. 1 controller

MH-II Supply Los Angeles Wear Machine Report

The test report should record the particle size category and test conditions used. 5.2 The wear loss of coarse aggregate should be measured by taking the arithmetic mean of two parallel test results. The difference between the two tests should not exceed 2%, otherwise the test must be repeated.

In addition, there are distributors, needle shaped gauges, three legged mesh baskets, and stone crushing value testers,
