1.存在问题目前沥青混合料生产普遍存在2个问题:一是所用石料来自不同石料厂,造成石料规格和级配不尽相同,即使是根据规范要求生产的石料,也会因为各厂所用破碎、筛分设备不同等因素造成石料规格不均匀。二是石料厂生产环境粉尘很大,会使石料所含石粉和尘土过多。现有沥青混合料搅拌站冷集料配料装置上没有筛分除尘装置,如果石料规格和级配不合格,会使沥青混合料搅拌
1. existing problems At present, there are two common problems in the production of bituminous mixtures: First, the use of different materials from the stone factory, resulting in different specifications and gradations of stone, even according to the specifications of the production of stone, but also because the plant used broken , Different screening equipment caused by uneven stone specifications. Second, large dust production environment stone factory, will make the stone contains too much dust and dust. There is no screening dust removal device on the existing cold aggregate mixing device of the asphalt mixing plant. If the specifications and grade of the stone are not qualified, the asphalt mixture will be stirred
