| RUBBER CONVEYOR BELTS |
Rubber conveyor belts consist of textile layers and rubber coating. The fabric is made from polyester in length -direction and from polyamide in cross-direction which grant appropriate tensile strength and flexibility for the belt. Rubber coating protects it from wear and damages coming from the environment.
| Quality and lifetime of rubber belts is strongly depending on the sefactors: | |
 |
adhesion between each textile layers (5 N/mm) |
|
adhesion between textil layers and rubber covers (4,5 N/mm) |
|
tensile strength of rubber covers (400 N/mm) |
|
elongation at break of rubber covers (400 %) |
|
abrasion values of rubber covers (150 mm3) |
Values according to DIN for the most spread EP 400/3 4+2 type anti-abrasive rubber belts with Y cover grades are listed above.
We keep the most spread EP 400/3 4+2 types in 500 mm, 650 mm, 800 mm, 1000 mm and 1200 mm widths constantly in huger quantities on stock.These good quality, anti-abrasive belts have an abrasion value of 150 mm3 or less (the smaller this figure is, the slower the rubber wears).
When material must be transported in at least 15-20 degrees height, there is need for profile belts. Depending on the features of the material and the lifting angle wevulcanise different types and sizes of rubber profiles onto the belts.

rubber belt with cross profiles |
CHEVRON belt |
We offer the following types of profile belts:
- original CHEVRON belts with 15 mm – 24 mm – 32 mm profile height
- profiles and cleats hot vulcanised onto the belt
- cold vulcanised profiles and cleats
If crushed material contains pieces of metal which can stuck in and cut the belt many meters long, it is worth to choose a rip-stop belt which has cross direction steel cords vulcanised in the fabric. They are strong enough to stop the belt when a piece of iron or stone begins to cut it.

| Available types: | ||
| CP 500/3 5+3 rip-stop belt with 5 mm top covering rubber | ||
| CP 500/3 8+3 rip-stop belt with 8 mm top covering rubber | ||
| CP 500/3 10+3 rip-stop belt with 10 mm top covering rubber | ||
| Steel cords have 1,35 mm thickness and they are positioned 8-12 mm away from each other. | ||
There are conveyor constructions where the structure is not completely staright, it begins with a horizontal part which turns into an uprising part afterwards. A Z-form structure usually first has a horizontal, then a vertical part and then again another horizontal section. The belts shall be pushed by the edges down, not to get out from the structure at the knick points. A cassette belt has to be supported also at the edges, because the side-wells and the cleats don'’t allow to use regular return rollers.
For such applications we recommend to use belts which can hardly be curved in cross direction.
We have them with 1 or 2 stabilizing layers in our programme:
XE 400/3 4+2 or XE 400/3+2 4+2
| Slinding belts: |  |
|
There are conveyor constructions where belts are not running on rollers but they are sliding on metal plates. The bottom rubber cover would slow down the belt very much, that is why for such applications our customers use belts with impregnated textile layer as bottom-cover which can easily slide on metal. We deliver such belts with 2, 3 or even 4 textile layers. |

| Oil and grease resistant belts: |  |
|
| They are mainly used in agriculture or in waste recycling where material can contain fat, oil or grease. These are very agressive for the rubber of normal belts. Therefore the covers of oil and grease resistant belts are made from a special rubber mixture. | ||
