The Role of a Cold Feed Bin in Asphalt Making Plants
Segregation of aggregates results to uneven, bumpy asphalt roads that are easily chipped or destroyed. That is why a cold feed bin is important in asphalt making plants. It is where production of asphalt starts. Usually, cold feed bins have 3 – 4 bins and feature steeply-angled side walls for reliable feeding of aggregate. A satisfactory asphalt road requires a uniform input of aggregates in the cold feed bin and a uniform output from the asphalt concrete.
Unfortunately, the life span of the cold feed bins are the least in the plant, since abrasive aggregates and high lift operators slamming buckets into their sides causes damage every time an operation is happening. Therefore, if you are planning to set up an asphalt concrete plant, pick a cold feed bin that is durable, has larger capacity, better accuracy and minimal on-site requirement assembly.
The problem with most asphalt companies is that they replace equipment only after it has been severely damaged. Moderately damaged cold feed bins can already bring about segregation and degradation of aggregates which would bring about unsatisfactory asphalt concrete. However, it is hard to blame them because replacing costs a fortune, so they just use the same equipment over and over again and just replace it when it completely breaks down. No wonder our asphalt roads gets damaged after just a short amount of time.
