Concrete mixer conversion – mixer life saved

Concrete mixer conversion – mixer life saved

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…

Optimization of concrete mixer

Optimization of concrete mixer

Our customer operates a concrete plant and uses a ring trough mixer. However, the mixing results leave more and more to be desired and the mixing time, a significant factor, is also getting longer and longer. The reason for this is worn mixing arms. These lead to a rotor encrusted with concrete.


Lining of a flap bucket

Lining of a flap bucket

Our customer has had a new flap bucket installed. However, the side walls are made of metal and completely unprotected against wear. We lined the bucket with PUCEST plates in 12mm and the “PUCEST round corner”. First, the bucket is measured and templates for the cuts are made. Cutting the panels and corners is possible with a jigsaw without any problems. The plates and corners are now screwed to the bucket. The perfect lining is ready.


Repair of concrete mixer

Repair of concrete mixer

Our customer’s concrete mixer was very heavily used. The mixer floor was worn and the slide valve was no longer functional, making it almost impossible to discharge the concrete. The walls of the mixer were also heavily corroded and were originally due to be replaced. Our suggestion to simply rotate the side walls was gratefully accepted – saving a lot of money.


The PUCEST shovel with carbide edge

The PUCEST shovel with carbide edge

The patented mixing blade combines the advantages of the PUCEST material with the benefits of carbide components. This means that the products are able to absorb and flexibly avoid any impact.

The carbide flakes of the carbide carrier plate form a protective layer in particularly stressed areas and protect the blades from wear caused by abrasive mixed material.
