How much does it cost to sell Los Angeles abrasion testing machines

1、 Purpose:

This machine is mainly used to measure the wear rate of stone materials.

2、 Structure:

This machine mainly consists of components such as cylinder, iron support, sealing cover, bracket, spindle, gearbox, motor, counter, etc.

3、 Main technical parameters:

　　1Cylinder inner diameter x inner diameter: 710±5mm×510±5mm

　　2Speed: 32±3Transform/divide

　　3Counter: 3Bit (automatic display, pre-set)

　　4Steel ball:Φ44mm-Φ48mm

4、 Usage:

　　1Before the experiment, it is necessary to check whether the circuit is intact and manually pull the drum to rotate normally (in the direction of the drum rotation arrow), while adjusting the counter to zero.

　　2Put the trial crushed stones and steel balls into the cylinder, seal and cover them, and tighten the screws. Start the instrument and rotate it 500 timesStop after turning and take out the sample.

　　3Using a diameter of 2mmRound hole sieve with a side length of 1.6mmSquare hole sieve, sieve out the stone chips in the sample, rinse the crushed stones left on the sieve with water, dry them to a constant weight, and accurately weigh the mass.

5、 Calculation method:

　　1Calculate the wear rate of the stone material according to the following formula, accurate to 0.1%.

Q=　　

Where:G--Wear rate of stone,%；

G1The original weight of the crushed stones loaded into the cylinder, g；

G2- The quality of washing and drying after the experiment, g；

　　2The results of the two experiments are the average of the two experiments, and the error between the two experiments is not greater than 2%Otherwise, a retest is required.
