Coal blending binder~The problem of asphalt melting at high temperatures in summer
Thread Content
Our company adds an additive, asphalt, to the coal blending. However, in the summer, the temperature in the raw material workshop is too high, which causes the asphalt to melt and seriously affects the coal blending. Is there any teacher who knows how to solve problems? Can you help me explain how to solve the problem? Please share your opinions, thank you
The granular ones also need to be crushed again. In summer, the temperature can reach over 90 degrees Celsius when the machine is running, so it will still melt.
It cannot be made into small briquettes and mixed into the crushed coal in a certain proportion and put into the furnace. Just like briquette coking.
This problem is not difficult to solve. The reason for asphalt agglomeration is that the softening point of asphalt is low. When purchasing asphalt and ordering, just ask for a higher softening point. My analysis is that you are using medium-temperature asphalt (softening point 75-90 degrees), which is easy to agglomerate. ； When ordering, buy modified asphalt (softening point 100--125 degrees). If the softening point is required to be above 115 degrees, it will generally not agglomerate, since the agglomeration is also very slight.

The joke upstairs is that modified asphalt is about 200 yuan more expensive than medium temperature asphalt.
