Preparation of continuous asphalt mixing plant after production

When continuous asphalt mixing plant mixes concrete, or when it is left to stand for more than 1 hour, in addition to removing raw materials, sand and cold water should be poured into the drum and put into the drum, and all mortar attached to the drum should be washed away. Don't let the water in the drum make the cylinder and blades rust. Stir and comb the ashes outside the drum together to keep the equipment clean.

Continuous asphalt mixing plants and mechanical equipment shall implement secondary leakage protector countermeasures, which shall be plugged in before application and shall be declared for use only according to the actual operation of the air switch. During the test run, the speed ratio of the mixing cylinder needs to be verified as appropriate. The general idling speed is 2-3 turns faster than the car (after the money is put in). In the case of more differences, the market share of the power car and the power car needs to be adjusted.　

For water conservancy and hydropower projects, a forced mixer should be used. When the construction site introduces a large amount at one time, the quality of the parts is high, and there is no support mixing plant in the vicinity, two mixing plants with small specifications or equipped with sub-concrete mixers should be selected.

Record the abnormalities of the continuous asphalt mixing plant: recording enables the technical engineer to identify problems, and it is important to immediately maintain and repair the asphalt mixing plant, such as the sound of the motor, transmission gears and other machinery and working equipment is normal, and stop immediately when there is a strange noise. Careful inspection during the operation of the continuous asphalt mixing plant.

Before using the grinding wheel, please check whether the standard parts are loose. Join the asphalt mixing plant for repair, turn and tighten, pay attention to whether the grinding wheel is cracked, tap gently with a wooden hammer with a loud sound, and start actual operation after about 30 minutes of no-load operation.

After connecting to the switch power, always pay attention to whether the mixer parts are working properly. When parking, always check whether the blades of the mixer are bent, whether the screws are popped out and whether they are loose. Set the small and medium-sized continuous asphalt mixing plant equipment on a flat ground, use wooden squares to top the front and rear drive shafts, and fix the empty tires to avoid rolling during use.
