Abstract

A conveying installation has a conveying belt and also has drums, loadbearing rollers and loadbearing frameworks. The conveying installation forms a material-conveying upper strand with a supply location for the conveying material and a mostly material-free lower strand. At least one drum and/or at least one loadbearing roller have/has a drum cover, which contains at least one layer composed of a foamed polymer mix.

First claim

What is claimed is:

1. A conveyor installation comprising:
a conveyor belt,
a plurality of drums;
at least one loadbearing roller; and,
a support frame;
wherein the conveyor installation forms a material-conveying upper web with an application site for the material to be conveyed, and forms a lower web;
wherein at least one drum and/or the at least one loadbearing roller has a drum covering which comprises at least one layer composed of a foamed polymer mixture;
wherein the foamed polymer mixture is selected from the group consisting of butyl rubber (IIR), ethylene-propylene rubber (EPM), ethylene-propylene-diene rubber (EPDM), polyacrylate rubber (ACM), epichlorohydrin rubber (ECO), chlorosulfonated polyethylene rubber (CSM), silicone rubber (MVQ), and fluoro rubber (FPM), or a mixture thereof; and
wherein an outer sheet of the drum covering is composed of the foamed polymer mixture.

2. The conveyor installation as claimed in claim 1 , wherein the foamed polymer mixture is selected from the group consisting of EPDM, ACM, ECO, CSM, MVQ, and FPM or a mixture thereof.

3. The conveyor installation as claimed in claim 1 , wherein the foamed polymer further comprises at least one pore-forming blowing agent that is an azo or diazo compound gas.

4. The conveyor installation as claimed in claim 3 , wherein the pore-forming blowing agent comprises at least one acrylonitrile polymer.

5. The conveyor installation as claimed in claim 1 , wherein the outer sheet is in the form of foil, woven fabric, and/or comprises at least one polymeric material.
