Loading hopper (hopper) in port facility

Material:

Fine-grained (sticky) to coarse-grained (approx. 2-10cm diameter) material from quarries

Problem:

On the one hand, there is a problem with caking when loading fine-grained (sticky) material and, on the other hand, sliding and impact wear when loading coarse-grained material.

Old service intervals: 

In principle not so much a problem with wear and tear on the system. The aim is to find a material that minimizes caking, but is still highly wear-resistant in order to ensure long service intervals even with coarse-grained material.

Alternative solution:

Since polyethylene is excellent at preventing caking, but is not particularly wear-resistant, lightweight rubber-ceramic composite panels were used.

Advantages

Extremely hard aluminum oxide ceramic with high wear resistance (in this case, light ceramic with a thickness of 4mm is completely sufficient)

Carrier for the ceramic 4mm rubber and therefore resistance to impact and minimization of noise emissions. In addition, easy and quick assembly through gluing.

Contact layer on the rubber for easy and quick bonding of the mats to steel surfaces.

Due to the significantly smoother surface of the ceramic compared to steel and stainless steel, caking in the system is minimized.

Since the ceramic has no tendency to absorb water, it also minimizes caking in extreme conditions (damp material, rain).

Relatively low material price.
