The ninth edition of the popular PUCEST in-house exhibition celebrated a minor anniversary on October 14, 2025. A total of around 150 interested parties and professionals from the field of wear protection took advantage of the opportunity to exchange knowledge, experience, and best practices again this year.
A worn-out paddle mixer can quickly become a problem. A worn mixer bottom and an old discharge chute lead to inefficient mixing and increase downtime. To restore the performance of a concrete mixer and make it future-proof, a comprehensive refurbishment is necessary.
The safe disposal of hazardous waste is crucial to protecting our environment from toxic substances. Proper treatment of these dangerous materials requires special facilities…
The customer’s conveyor belt, which transports large quantities of sand every day, suffered from significant material residue on the underside of the belt. Manual cleaning was laborious and time-consuming, which affected production.
The cause of this material loss was in the conventional side guide made of sheet metal. This did not provide sufficient support for the fine shell sand, which led to considerable material loss and unnecessary cleaning work. The solution: The PUCEST material management
PUCEST pipe lining is designed to adapt to specific requirements. The lining can be manufactured for pipe segments in various sizes and bends, enabling flexible application in complex systems.
PUCEST protect, the specialist for high-performance wear protection solutions, has once again demonstrated its expertise in optimizing systems. A project with a customer impressively demonstrated how a serious wear problem on a critical plant component, a rotary elevator distributor, was quickly and sustainably resolved.
In industry, where machines and systems are exposed to extreme loads from abrasive materials on a daily basis, wear protection is essential. But not all wear protection is equally good. A common mistake is to assume that the hardest material is always the best choice, without taking into account practicality, ease of installation and reparability. An illustrative example of this is the use of a spray house lining on a vibrating chute.
An illustrative example of PUCEST’s effectiveness and comprehensive service is a recently completed project for one of our customers, in which a heavily used concrete outlet in a production plant was optimized.
One of our customers had a weighing belt that was experiencing significant problems, which were impairing the material flow and leading to unwanted material leakage. The original seals were severely worn, which meant that conveyed material could leak through the side guides.
The material guide on a 25-meter-long weighing belt was severely worn—both the carbide guide and the plastic plates above it. After removing the protective grilles, the old lining was dismantled.
Our customer’s concrete discharge hopper was completely worn out. Our customer had already dismantled the hopper and made it available. However, the basic structure was so badly damaged that we manufactured a completely new bar hopper directly on site.
The lining of the aggregate scales was heavily worn at the impact points. We removed the old material, cleaned the substrate and made templates for the new panels.
“At last we can breathe a sigh of relief! The installation of our new easycleaner is complete – and what an improvement in cleaning! I can’t believe it only took 2 days to install! That means much less effort and more efficiency for us.”
The PUCEST blow-in elbows are used for conveying fine-grained material. The conveying material collects in the honeycomb-shaped pockets, thus preventing turbulence in the air flow and the collected material also serves as wear protection.
13 years is a very long time for a lining. Our PUCEST material is extremely low-wear and keeps its promises. The old lining was removed, new segments were cut from PUCEST sheets in 12 mm with aluminum perforated bleaching insert and screwed into the hopper. When dismantling the hopper, the customer cut away the permanently attached belt seal and our fitters quickly produced a new removable construction on site. This means that all components can be replaced quickly and easily.
Our customer’s concrete discharge hopper with a rubber lining was badly worn. Our installation team dismantled the hopper, removed the rubber lining and took the exact dimensions of the inlay. Now our PUCEST panels can be cut to size and the inlay is completely manufactured on site. Reassemble everything and the funnel is perfectly protected against wear. Reduced cleaning effort, much longer service life and therefore cost savings. PUCEST the original, made in Germany.
The inlay of the funnel is badly worn. Our team dismantles the hopper, removes the old lining, then cleans and primes it. Now the new PUCEST lining made of 12 mm sheets with perforated aluminum plate in 85 Sh can be installed. Before the new hopper can be attached, a new mixer cap is fitted and the hydraulic lines are replaced. Everything is ready for use again…
Our customer’s concrete mixer is leaking, with liquid and material constantly escaping from the mixer lid. We welded 2 mm thick metal sheets into the gap and then sealed everything with PUCEST TIX filler. The mixer is now absolutely leak-proof.
The transfer point was perforated several times and falling material had to be removed daily. In addition, the material guide on the sides had already been “patched” several times. Our installation team first installed a PUCEST head scraper so that material residues underneath the conveyor belt were no longer a problem. Now we were able to line the sides at the transfer point with the PUCEST material guide. In addition, impact protection was installed at particularly affected areas.
The old lining consisted of wear plates and rubber flaps and was completely worn out. A permanent solution had to be found. First of all, the old lining had to be completely removed.
We found a defective rotor and worn mixing arms. Normally, the mixer would be disposed of and a new one would have to be purchased. However, our experts were able to perform a true miracle and bring the mixer back to life. With the PUCEST universal mixing arm and the many years of experience of our fitters, we were able to do it again this time…
Replacement of a silo ventilation filter. The old filter was extremely clogged and no longer fulfilled its function. A repair was not possible.
Lining of an elevator bucket with PUCEST sheets 10 mm in 85 Shore and the PUCEST “round corner”. Even before the bucket is installed in the factory, we take over the lining to prevent adhesion right from the start.
Our customer’s mixer lining is completely worn out. In addition, the discharge hopper has considerable cracks. A second mobile hopper is also to be lined with PUCEST. We bring the external hopper to our workshop so that we can work on the project in parallel.
A sedimentation tank is used to collect suspended solids from the water at the bottom of the tank. To prevent the concrete residue from hardening, an agitator is used to keep the recycling water and suspended matter in motion.
The discharge hopper of our customer’s concrete mixer is completely worn out. Material sticks everywhere and prevents the concrete from running off smoothly. The discharge hose for filling the vehicles is also completely worn out.
Our customer’s material feed hopper was pretty battered after a few years. Instead of a new hopper, which would have meant considerable costs and downtime, we suggested lining the hopper with PUCEST panels with a perforated plate insert.
Our current patient was a ring trough mixer with a cracked rotor and completely embedded clamping and spring elements. The customer was unable to obtain a new rotor quickly. Installing a new mixer was out of the question for reasons of time and cost.
The seals were worn and material could seep through the side guides. The side guides were made of steel and were quite damaged in places. Our assembly team used PUCEST plates and the PUCEST material guide to repair the Wiegand. A lot of drilling and screwing was now required.
Our customer’s hopper was not lined. Due to the structure of the metal sheets, material residues were accumulating and solid caking was formed. We received the order to completely line the hopper to prevent major wear. We took on the task with our PUCEST panels with perforated metal inlay.
Our customer operates a loading chute in the metal processing sector. A very large number of screws run over the chute. Due to high temperatures, the PU used in the outlet area has dissolved in places. In order to be able to continue operating the chute, the wear protection used would have to be replaced.
At our customer’s plant, there were repeated problems during transportation on the conveyor belt. The material (mainly sand) ran under the side guide and the entire conveyor belt had to be completely cleaned at relatively short intervals. The PUCEST material guidance protects the belt and ensures an even material flow.
The cleaning of conveyor belts is always a topical issue. Residues cause high costs due to material loss and cleaning effort. The belts, rollers and system components wear out prematurely. Efficient belt cleaning is therefore urgently required for adhering goods.
Our customer’s ring trough mixer was badly damaged, the gearbox was worn out and the mixing arms were corroded. It was no longer possible to adjust the mixing arms. We completely dismantled the mixer, removed the gearbox and repaired it.
The success story continues. The next easycleaner is at our customer’s premises.
The easycleaner really makes work easier for the employees, the short cleaning program for in-between only takes about 1 minute, a complete cleaning only 4 minutes. A considerable time saving compared to the time-consuming cleaning previously required.
The rubber lining of the material feed hopper was damaged and there was heavy caking in several places. We removed the old lining and sanded down the hopper. The hopper was measured, templates were made and the PUCEST AHA sheets were cut to size accordingly. The PUCEST AHA (anti-adhesion plate) is particularly suitable for this application.
Our customer operates an insertion chute in the metal processing sector. A very large number of screws run over the chute. Due to high temperatures, the PU used in the outlet area has dissolved in places.
