A PROCESS FOR THE PREPARATION OF CARBON BLACK PELLETS |
摘要 |
<p>The present disclosure envisages a process for pelletizing carbon black by mixing carbon black powder and water in a proportion in the range of 0.1:2 to 2:1 with a binding agent and a dispersing agent. The dispersing agent is an amine-based surfactant and is added in a proportion in the range of 0.005-0.1% of the total mixture. The mixture is pelletized in a pelletizer and subsequently the raw pellets are dried for 20-60 minutes at a temperature between 150-250° C., to obtain the carbon black pellets. The process of the present disclosure provides uniform distribution of water on the surface of the pellets giving a uniform pellet quality, reduced water consumption, energy savings and an increased production rate.</p> |
