Continuous gradation mixing floor

On the one hand the measurement of aggregate and transport feed efficiency is low, resulting in a mixing efficiency of the actual production is less than the theoretical value ; the other hand, aggregate , ready mix concrete plant cement into the mixer while stirring the instantaneous mixing exerted pressure on the host , mixing uniformity affected to a certain extent , these two drawbacks has restricted the traditional mixing station to enhance mixing efficiency and quality. Continuous gradation Concrete mixing plants upstairs ingredients used alone weighed in the form of reduced aggregate metering and transport time ; while using secondary feeding method, which is to put cement, sand , water, admixtures, after short mixing a few seconds , then put aggregate grain stone , making stirring time without affecting the premise , to effectively improve the concrete homogeneity .
