GKD to Present Integrated Process Belt Expertise for Key Industries at ACHEMA

The company will be showcasing process belt solutions made of mesh and spirals for thermal treatment, dewatering, and filtration to the international trade specialists.


The process belt specialists from GKD – Gebr. Kufferath AG will be presenting three focus topics at ACHEMA, World Forum and Leading Show for the Process Industries. From June 11 to 15, they will be showcasing process belt solutions made of mesh and spirals for thermal treatment, dewatering, and filtration to the international trade specialists in attendance in Frankfurt. The focus of the trade fair appearance is on the integrated expertise of the technical weavers. Process-dependent, custom product development and technologically leading manufacturing from a single source underline the efficiency of GKD belts that is in demand worldwide. Based on past experience, the belt experts are a sought-after contact at the ACHEMA event among equipment manufacturers and users for discussing concrete challenges.

Process efficiency and reliability are the top priorities for all protagonists in the process industry. Continuous, uninterrupted production, high system availability, and perfect product quality are key success factors for critical applications. Whether drying, cooling, or freezing in large systems, preparing industrial process and wastewater, sewage sludge dewatering, or filtration of fertilizers or cooling lubricants: process belts from GKD play a key part in all of these applications.

Dewatering and Filtering

Filter Belts from the VACUBELT® Product Range from GKD Surpass the Performance of Conventional Filter Belts.

Wastewater and sludge from the process industry place strict requirements on the mechanical, thermal, and chemical robustness of the process belts used for their dewatering. GKD filter belts are proven and enjoy an enviable reputation in the field of process water treatment in the chemicals industry, as well as the paper industry and pectin production sector. Belt 1003 is unparalleled in terms of its transverse stability, dewatering performance, and particle retention. GKD now offers this filter belt, which is known worldwide, as standard with integrated wear indicator to provide greater assistance in determining mechanical abrasion. A contrasting-colored core in the woven polyester monofilament provides an early visible indication of the degree of process-based wear or incorrect belt adjustments after loading the belt. This makes it possible to plan belt changes and promptly implement any necessary corrections.

For applications with fibrous sludges, which are less capable of flowing, such as those typically encountered in the paper industry, GKD offers the “1003” of spiral belts for pre-dewatering and belt presses. This belt was developed and is also manufactured in-house. The seamless belt has only been available for around one year but has quickly made the transition from insider tip to successful product thanks to its excellent performance and is now being used in over 100 systems. Its special stability can be attributed to the refining process, which involves strong drawing. This specific post-treatment reduces any undesirable elongation of the belt in the process and completely eliminates the need for readjusting the belt tension, which is necessary with all conventional belts. This spiral belt therefore combines the benefits of a seamless dewatering belt with the transverse stability of a woven belt. In the food sector, linear screen belts with FDA-approval are in demand worldwide for applications such as salad washing.

GKD Offers the Belt 1003 Now with an Integrated Wear Indicator to Provide Greater Assistance in Determining Mechanical Abrasion.

Used in continuous vacuum belt filter systems, filter belts from the VACUBELT® product range significantly surpass the performance of conventional filter belts when dewatering FGD and phosphorous gypsum, as well as potash. Their special mesh design with apertures from 50 to 500 μm impresses thanks to its optimum air permeability, constantly high filtration performance, low clogging tendency, as well as its good cleaning characteristics. Thanks to their resistance to the high stresses encountered in the process industry, they offer the best prerequisites for a long service life. The particularly flat PAD seam also makes a key contribution to this through significantly reduced particle penetration. The transverse and tracking stability of the process-specific VACUBELT® filter belts also contribute to the success of this product range. Their excellent characteristics profile has enabled the rugged belts made of polyester monofilaments to become the global leaders for exacting large-scale filter processes. Its exceptional performance is what speaks for this belt type, also in the field of cooling lubricant filtration in central installations of the metalworking automotive supply industry. During the ACHEMA fair, users and equipment manufacturers can get a much clearer picture in person of the performance spectrum offered by GKD process belts for the numerous special applications in the process industry. The tried and tested problem solvers at GKD are popular conversation partners when it comes to discussing new challenges and potential solution approaches.
