The bulk hopper & feed hopper is fed with material by wheel loaders. The material is discharged by a belt conveyor. We received the order to completely line the hopper to prevent greater wear. We tackled the task with PUCEST panels and round corners. First, residual material was removed and the hopper was cleaned.
An extension of the service life of the steel material from approx. ½ year to more than 7 years with the changeover to the material PUCEST. Once again, in this case probably disproportionately, the longevity of the material PUCEST is demonstrated. The examination of the conditions on site and the correct plate thickness and Shore hardness ensure an optimum result.
After using the PUCEST® lining, the caking and sticking of the material has improved considerably. The overall material flow is significantly optimized. As a result, we have been able to increase the output of the entire plant and relieve the employees, which in turn creates more time for their actual tasks.
On our conveyor belt, various raw materials are delivered and conveyed to storage silos. Due to poor seals and scrapers, we had considerable contamination on this belt and the associated costs were no longer acceptable. Since this belt is mounted in a basement, the cleaning was very time and labor intensive.
In our search for alternatives that – with regard to their price-benefit ratio – generate added value for us and our customers in the long term through significantly lower maintenance and wear costs with simultaneously longer service lives, we found what we were looking for at PUCEST® protect GmbH in Elsenfeld.
All the grit from the screening plant (approx. 600,000 t/p.a.) is conveyed at 2.5 m/s, then has to be stopped in order to fall onto the trucks. Usually material pads are built up as wear protection, which is not possible here due to the mixing of grains.
The PUCEST® System impact beams with their individual blocks were mounted on the impact rocker bars in the customer’s own workshop. In week 01/2016, the preparation plant was started with the production cycle described above. No abnormalities could be detected during the respective shutdowns.

It is a mixer high-pressure cleaning ” Easy Cleaner” ( 3 cleaning heads ) which we have in our factory in a Pemat 2m² mixer with whirler in use.
The new original Pucest elbow has significantly improved the service life. This has saved repair, downtime, and personnel costs for maintenance. The fast and uncomplicated delivery time is praiseworthy.
The wear is minimal as seen in the photo, also the visible adhesions here loosen as already described last year with time independently. We have not had to clean this gutter until today!
The bulk material & feed hopper is getting a bit long in the tooth. In order not to have to completely replace the plant part at some point, we recommended the lining with PUCEST. First we installed PUCEST panels in 2 places for testing. After a few days the customer was convinced of the performance of our material and we received the order for the complete lining.
Extremely fewer repairs, service life extension, cost saving, better faster cleaning, easy fast renewal of wear parts, better mixing intensity due to PU bottom, less caking

With the PUCEST High Performance Channels we were able to carry out the first trial linings. Since the installation approx. 1.5 years ago, the troughs have been almost wear-free until today. After only one year we decided to use these trough linings also on the other balancing troughs.
In our vibro-press manufacturing process for the production of concrete light wells, the tops are pressed in with the help of a hardened steel top sleeve. This top sleeve, with dimensions 100 x 50 cm, has a price of 4500,00 € and must be replaced every 2 months (approx. 3000 cycles).
The concrete hopper is intended to store bulk material and transfer it to a conveyor belt. Concrete is not really suitable for abrasive materials. With the lining by PUCEST plates the construction is effectively protected against wear. The hopper with PUCEST lining has now been in use for more than 4 years and still works perfectly.
The Waibel company successfully uses the wear protection solutions of the PUCEST company as edge protection on the hopper for its concrete pumps. From our own experience, the material of the company PUCEST is more resistant, more durable and remains soft despite formwork oil and does not attack the material.
Since the PUCEST material guide has already been installed in the other ready-mix concrete plants with great satisfaction, we have again decided to use the PUCEST material guide. This is screwed to the side guide plates in the upper area due to the cast-in perforated steel plate.
Problem: rapid and high wear of the rubber lining used, which had to be replaced every 5-6 months at the latest. The rubber sheets were swollen and worn down over a large area due to the use of formwork oil and mixer protection.
Based on the experience we have already gained, we are convinced of this material for the application. Since we also use other products from PUCEST, which also work very well, we are very satisfied with the general quality and will also use PUCEST in other applications in the future.
PUCEST step plate test phase: one year of production is over: time to present a result. Application: Discharge distribution tower and marl hall for raw material. High abrasive load with different grain sizes, dry as well as wet 0-120mm. A result that can be seen…
A time saving of almost 3h per day, which the staff can use for the actual tasks. Target fulfilled. After 7 months in operation, no wear is visible. The purchase of a second hopper of the same design is being considered.
The Pucest lining was installed on 18.09.2016, and no wear could be detected during the semi-annual inspection on 13.03.2017 and on 17.09.2017. Due to these extremely positive experiences, the Hexagon Protectors were stocked by us and installed in further plant sections where grade purity is not required. Also with positive experiences.
