How to safely operate small asphalt mixing equipment
1、Small asphalt mixing equipment should be set on a level ground, with square wood to the front and rear axle pad, fixed overhead tires, to prevent the use of sliding phenomenon.
2、Check whether the transmission clutch and brake are sensitive and reliable, whether the connecting components are worn, whether the track pulley is outstanding, whether there are obstacles around and the smoothness of each part, etc.
3, the direction of rotation of the mixing cylinder should be consistent with the direction of the arrow, such as non-conformity, should correct the motor wiring.
4, small asphalt mixing equipment should be implemented in the second leakage protection measures, before using the power supply by the empty car operation qualified, before the official use. Test run should test the mixing cylinder speed is not appropriate, usually, the empty speed than the car (after loading) slightly faster than 2 - 3 rpm, such as the difference between more, should adjust the dynamic wheel and the share of the transmission wheel.
5、When stop using, should pull the gate and power off, and lock the switch box to prevent others from misoperation.
6、When the concrete mixing is finished or estimated to stop for more than 1h, in addition to the residual material out of the net, use the stone and water to pour into the shaking cylinder, start the machine rolling, the mortar stuck in the cylinder flush clean and unload out. There should be no water in the barrel to avoid rusting of the barrel and blade. Together with the mixing cylinder should also be sorted out outside the ash, so that the machinery to keep clean and intact.
7, after the start, often pay attention to the operation of the mixer parts is normal. When the machine is stopped, often check whether the mixer blade is bent, whether the screws are knocked down or loose.
