    • 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.
    • 本公开设想了一种通过以0.1:2至2:1的比例混合炭黑粉末和水与粘合剂和分散剂来造粒炭黑的方法。 分散剂是胺基表面活性剂,并且以总混合物的0.005-0.1%的比例加入。 将混合物在造粒机中造粒,随后将原料颗粒在150-250℃之间的温度下干燥20-60分钟,得到炭黑颗粒。 本公开的方法提供了在颗粒表面上均匀分布的水分,其具有均匀的颗粒质量,减少的水消耗,节能和提高的生产率。
