CONSISTENTLY BETTER This special know-how developed into the drive motor for the reframing of Zeppelin’s business activities after World War II. The first standard aluminium silo was produced as early as 1950. Other innovations, such as the devel­ pment of emboxable silos in the o 70ies and the technology for easy on-site assembly of si­­ – even los those larger than 500 m³ – enabled Zeppelin silo technology to grow consistently. Silo production has a long tradition at Zeppelin. The company welded tanks from aluminium already in the days of airship construction in the early 20th century. Always...

Selection diagram for blending silos Multi-Pipe Multi-Flow Powders with easy flowability 50 – 500 μm Pellets with easy flowability 200 – 3000 μm Powders with poor flowability OPTIMUM BLENDING RESULTS Blender size [m3] (maximum) Type of energy input Specific energy requirement [kWh/t] Due to process or raw material fluctuations, it is not always easy in plastics processing or plastics recycling to achieve a consistently high level of product quality. With blending silos from Zeppelin, the fluctuations can be offset, which leads to far better results. The standard versions of our broad product...

Typical use of blending silos for the production of polyolefins Depending on your requirements and the respective product properties, you can choose from several blending concepts. Please consider the following selection criteria: Product and flow properties Powder with poor flowability, pellets or powder with easy flow-ability? We have the right blending silo for every product property. Required homogeneity depending on the blending time How homogeneously must your product be blended so that it can be processed in an optimum way? Cleaning Do you change products or colors frequently? Then fast...

Zeppelin Centro-Blend silo Applications The versatile blender is suited for bulk materials with easy to poor flowability and is suitable both for continuous and discontinuous blending. The Multi-Flow blending silo is the ideal choice particularly for retrofitting conventional silos with blending technology. System description The Zeppelin Multi-Flow blending hopper generates various flow velocities in the hopper and the lower cylinder area. This results in different dwelling times, which have an impact on the blending effect. Multi-Flow blending silos with a height-to-diameter ratio of < 2.5...

Applications The blenders are ideal for bulk materials with good flowability such as pellets with particle sizes of more than about 0.5 mm. They can be used for continuous and discontinuous blending. System description The bulk materials are withdrawn by vertically running blending pipes inside the blending silo from 18 different levels at the same time and fed into the blending chamber. Inside the blending chamber, the 18 sub-jets are mixed with the product jet from the central outlet of the blender before being discharged. To achieve this result, 6 blending pipes with 3 compartments are used....
