Carbon black and silica
A consistently good performance
Technical innovations, such as a patented slow conveying process for carbon black beads and silica that are considered a pioneering concept within the industry, underline the excellent reputation that Zeppelin enjoys within the rubber industry.
Raw materials in powder form must be conveyed pneumatically in hermetically sealed systems in order to ensure that there is absolutely no dust in the system and surrounding area. The lowest possible conveying speed is a decisive factor for the product-friendly conveying of sensitive products, such as carbon black or silica.
Very different qualities of carbon black and silica are used in modern rubber compounds. The conveying system must always be dust-free and work reliably and at a constant performance despite the different characteristics and flow properties of these raw materials. Our patented conveying processes ensure gentle and reliable conveying at all times.
