What should we pay attention to when choosing equipment of engineering mixing station? The mountain road construction site is inconvenient in traffic, and it takes a lot of time for maintenance personnel to enter and leave the construction site. It is best to use the same small-sized double-machine station or prepare enough Spare Parts to ensure the smooth construction progress. The construction sites are scattered, but the distance between the construction sites is not too far. The transportation radius of concrete truck is less than half an hour's drive, and that of dump truck is less than 10 minutes' drive. It's best to use multi-work-number centralized mixing to improve the utilization rate of mixing station and the economic benefit of construction.
