Whether it is a continuous or a batch process – only one thing counts in the long run: a clearly defined, consistent material quality that excels in stability, reproducible grain size distribution and homogeneous properties as far as color, melt viscosity, composition, and / or moisture are concerned.
Coperion Waeschle has the know-how and design experience on plants and components to meet any process requirements with the maximum reliability and cost-effectiveness. For example, our silo mixers ensure the homogenization of products of a variety of grain sizes with a special by-pass sealed flow conveying systems, that preserves the range of grain sizes by their gentle transport. FLUIDSTAT® is an example of such a conveying system that transports powders efficiently, over long distances, with an internal by-pass. In addition, thanks to the most up-to-date gas injector technology, FLUIDSPLIT® provides an optimized plug flow conveying system for cohesive or abrasive powders. Combined with the RCP product feed station, this offers the ideal conditions for fully exploiting the process-optimizing potential of the most modern conveying system technology.
New powder valve design!
Optimized design for higher filling efficiency, maximum volumetric performance and minimum air leakage – the ZX series valves feature a blow-through channel with a larger connection diameter and a specially shaped groove.
Innovative high-pressure powder conveying!
By optimizing design and construction features, it has been possible to implement a new technology for high-pressure powder valves. We utilize the sealing effect of powder combined with specially adapted rotors, which is advantageous for both the conveying performance and the amount of air leakage. This new technology is available as a discharge valve and a blow-through valve, and reduces investment and operating costs because of its increased reliability and lower maintenance requirements.
Double-pipe cooling technology with pneumatic conveying!
For products conveyed pneumatically at high temperatures, standard series of water-cooled, jacketed pipes have been developed in order to cool the products during conveying. This method is used successfully for cooling powders such as PTA ( terephthalic acid) , and also polyolefin powders.
BULK-X-CHANGE bulk products heat exchanger.
• Contact heat exchanger with excellent heat transfer
• For all free-flowing powders and pellets
• Simple, space-saving construction
• Cost-effective system, particularly with respect to operating costs
EXAMPLE
Many powders have the unpleasant property of tending to cause dust explosions when finely distributed in the air. This must be taken into consideration when designing plants. The new ATEX guideline sets limits and guidelines for this. Comprehensive expert knowledge of bulk product behavior, plant design, and operational safety is necessary for this. Coperion Waeschle employs highly qualified personnel who are specialists in these areas and contribute their planning and advice competencies in all questions and problems relating to this topic.
In one case, a big-bag discharge for Bisphenol-A, designed by the operator, resulted in a dust explosion. In order to avoid such accidents in the future an innovative controlled extraction design was developed so that an ignitable dust / air mixture cannot be formed.
KNOW-HOW
Whether it is for an individual component, a small system, or a turnkey plant, Coperion Waeschle is a strong partner trusted by the industry. The planning, design and implementation of the plants always meets the specific, stringent demands and high safety standards of the industry concerned.
Regardless of whether the solutions are intended for the plastics industry, chemicals industry, minerals industry, or food industry, plant safety and operating safety are always in the forefront in concept development and process engineering configuration. All individual customer demands are taken into consideration, as are the quality and physical properties of the products to be conveyed. Together with the customer, Coperion Waeschle develops configuration variants optimized with respect to investment and operating costs, product quality, and other specific requirements.
For explosive dust / air mixtures, the necessary explosion protective measures are taken, e.g. making the systems inert, as well as using mechanical means such as determining the appropriate design pressures and the use of rupture disks. Certain components such as valves or diverter valves are selected for each case in order to specify precisely the necessary deviations from the standard design. To this end, components such as Gas Control Stations, mixing cones, elutriators, or product heat exchangers are defined in relation to the project and configured accordingly to process engineers.
Components
A plant is only truly safe to operate when each individual component meets its requirement. In order to ensure that an optimum quality level is attained, Coperion Waeschle develops, produces, and tests the components with the appropriate key functions in our in-house plant. These components essentially include rotary valves, pipe diverter valves, and shut-off units.
When conveying at pressures of –0.5 to +6 bar, with a wide range of varied bulk product behavior, the rotary valves face a process engineering challenge. These challenges are overcome with unrivaled efficiency, using the new ZXD, ZXQ, and ZAQ blow-through valves developed for powder handling.
Conveying pipe diverter valves must be sealed during powder conveying, but must also switch reliably in spite of sticky or hardening products. The broad selection of Coperion Waeschle diverter valves offers the right solution for every task.
Coperion Waeschle shut-off valves ensure a reliable interruption of the flow of bulk product and at the same time prevent leaks to the outside.
New large-scale plant with unparalleled flexibility
In the Spring of 2004, Coperion was commissioned by Basell Polyolefine GmbH in Wesseling to put pneumatic conveying systems into operation in one of the largest and most versatile world-scale PE plants ever built. Together with Tecnimont S.p.A., Coperion engineered and delivered the large-scale plant. The 21 different Coperion conveying systems used represent a cross section of current systems. This plant is unequaled, as far as operational flexibility is concerned, due to the large number of switching and parallel operations installed.
