Profit from our experience in handling demanding products like Carbon Black, Silica, Kaolin, Zinc Oxide, Sulphur and other cohesive and non free-flowing powders. Whether at the bulk silos or the smaller day-bins and receiving hoppers special designs & technologies for Mass Flow, Filtration, Discharge Aids and Dosing guarantee reliable storage of the raw materials for your Rubber Compounds as well as a Dependable Discharge, Accurate Dosing and a working environment free from Dust Emissions. Right from the Product Intake you will profit from Zeppelins System Competence. Deliveries of material in many variations of Bulk or FIBC transport must be managed and unloaded flexibly, quickly, reliably and free of emission. It must be transported by special conveying methods Optimized and Adapted to accommodate the Material Characteristics. 8

Pneumatic Conveying Dust Free, Reliable, Low Fines Generation. To ensure an absolutely Dust Free System and Workplace, the powdery raw materials have to be conveyed pneumatically in closed systems.

For conveying with Minimum Fines generation the Conveying Velocity is critical. For Sensitive Products like beaded Carbon Black or Silica we target the lowest possible velocities (< 10 m/s).

In modern Rubber Compounds in the tire industry very different qualities of Carbon Black and Silica are used.

For Dense Phase conveying we use our patented by-pass conveying systems (Overflow) where a controlled quantity of secondary air is put into the pipe at defined intervals, preventing material plugs

These optimize the system to suit the flow characteristics of the carbon black and silica grades for Minimum Fines. Secondary Air Injection with Overflow Valve.

9 Pneumatic Conveying Dust Free, Reliable, Low Fines Generation. To ensure an absolutely Dust Free System and Workplace, the powdery raw materials have to be conveyed pneumatically in closed systems. Depending on the Characteristics of the Product, QA requirements and Equipment Configuration we can offer vacuum or pressure systems and Dilute, Dune or Dense Phase Conveying Processes. For conveying with Minimum Fines generation the Conveying Velocity is critical. For Sensitive Products like beaded Carbon Black or Silica we target the lowest possible velocities (< 10 m/s). For less sensitive products (i.e. zinc oxide) or less stringent fines (< 125µ) limitations we can utilise simpler high speed technologies. In modern Rubber Compounds in the tire industry very different qualities of Carbon Black and Silica are used. Despite the very different characteristics and flow properties of these raw materials the conveying system must operate reliably, dust free and with the specified performance at all times. For Dense Phase conveying we use our patented by-pass conveying systems (Overflow) where a controlled quantity of secondary air is put into the pipe at defined intervals, preventing material plugs from blocking the line. For the air regulation we can utilise our patented intelligent air management systems (AQU) which regulate the airflow automatically. These optimize the system to suit the flow characteristics of the carbon black and silica grades for Minimum Fines. Secondary Air Injection with Overflow Valve. The AQU (Air Quantity Unit) is a key element of the system as it Regulates the airflow according to the Product, Conveying Distance and Pipe route. Stored data allows the operator to select the product and target hopper and the Velocity is Automatically Controlled independent of line pressure. Carbon Black with High Fines Content after conveying with too high a velocity. Below: Carbon Black with a Minimum Fines Content after optimized conveying. 9

10 Feeding / Dosing and Weighing High Precision Mixer Feeding A Prerequisite for short Cycle Times and High Productivity is the exact and quick Dosing of the formula Components (Polymers, Powders and Liquids) as well as the Reliable & Complete Discharge of the scale contents into the mixer. Of course the system must also avoid dust emissions into the workplace while minimizing product losses. Weigh Hopper with fully fluidised cone Mixer Feed Chute with Off-Spec Discharge Feeding / Dosing are affected by Dosing Screws, Rotary Valves, or Conveying Lines which are adapted to the products and work with adjustable frequency controllers. Our Weighing Systems, including the down-stream mixer feeding chutes, guarantee accurate batches and rapid, complete emptying into the mixer. This is Ensured by use of suitable Weigh Hopper designs, Discharge Aids, Fluidisation, Venting techniques and Non-Stick materials. This makes it possible to empty the scales in a very short time without the risk of residual material sticking in hoppers, drop chutes and mixer feed chutes. This in turn ensures the Accuracy of the Batch Formula right to the mixer. Dosing screws can only work effectively if the product characteristics, product intake and cycle time are considered and matched to the screw size, geometry and design. The system must also be able to isolate the influence of pressure variation and in-flight material. 10
