Granulation of carbon black #18 big reason

The amount of carbon black powder added, the thickness of the carbon black particle bed, the rotation speed of the drum, etc.

If too much carbon black powder is added, the relative density will be smaller and it will be more difficult to granulate. If the particle bed is too fine, the risk of physical aggregation between particles is reduced, slowing the rate of granulation. Only when the drum rotates at the appropriate speed can the carbon black maintain a certain slope in the drum.

Carbon black granulation relies on the mutual extrusion between carbon black powder and the moving original carbon black particle cores.

What components of coal tar affect the granulation of carbon black?

That's right. Most of today's carbon black is produced by the furnace process, but the granulation process is divided into humide. granulation and dry granulation processes.

Wet granulation involves adding water and binder to powdered carbon black through a granulator to form granules, and then drying them.

Dry granulation uses a bevel open granulator for carbon black masterbatch and carbon black powder. No need to add water, no need to dry. However, due to heavy pollution, backward technology and low yield, dry granulated carbon black is basically no longer available.

The powdered carbon black you are talking about must be powdered carbon black that has not been granulated. The data system index is not significantly different from that of granulated carbon black, and it will have certain effects in different uses. . For example, during the rubber mixing process, the material is consumed slowly, the volume is large, and the ststorage is impractical.

Granulation in carbon black factories is a special type of work.

The quality of coal tar does not affect the granulation of carbon black. Poor granulation of carbon black depends on the speed of the granulator. and the granulation is related to the amount of carbon black in the machine. Our company has already experienced this situation. When the granulator rotates too fast or there is too much carbon black in the granulator, it is easy to produce powder. If it is wet granulation, the influencing factors are nothing other than these two factors.
