First of all, the selection of the delivery pump in the asphalt mixing station must meet the requirements of the maximum asphalt pouring time per unit time during construction, the higher height, and the larger horizontal distance. At the same time, there must be a certain amount of technical and production capacity reserves, and the balanced production capacity is preferably 1.2 to 1.5 times.

Secondly, the two major systems of the asphalt mixing station, the movement and hydraulics, must be normal, and there must be no abnormal sound and vibration to avoid large aggregates and lumps inside the equipment, otherwise it is easy to get stuck at the feed port of the mixing station or be blocked due to arching. Another point is that when the asphalt mixing station is in the same site, it is not suitable to use too many pumps and pumps from multiple manufacturers to avoid affecting its normal operation.
