The Low rolling resistance (LRR) trough belt is well studied in theory tested in lab and proven in conveyor applications. This article describes a methodology that analyses LRR pipe belts and introduces recent applications of LRR pipe belts on overland pipe conveyors that reduces power consumption and improves performance.
Such belt types on long distance conveyors can save a lot of money. They are marketed as LRR XLL or EOB conveyor belts. For the determination of the energy saving properties of a conveyor belt a standardized test described in DIN 22123 has been implemented.
The belt is supplied with a Low Rolling Resistance (LRR) cover on the pulley side. Our innovative approach has enabled us to take a lead in offering special cover grades with Powersave features to fit
When the belt was replaced with a belt with non LRR pulley cover rubber the conveyor motors could only support 7 000 mt/h capacity. However in the case of the ST10 000 where high elevation change is involved the rolling resistance benefit is significant-ly reduced as the energy required to lift the material becomes dominant.
Use these belt scrapers to remove debris from conveyor belts. If a chip of this blade breaks off near a process line it can be located by metal detectors to reduce contamination risks in food processing applications. Food-Grade Conveyor Belt Scrapers.
Sep 21 2018 · The Belt Conveyor is a machine which can continuously transport material. The transmission principle of friction to drive the material through the roller and the tape. The belt conveyors are widely used in metallurgy coal hydro power building material chemical industries and various other sectors. The Belt Conveyors
Conveyor Belts Save Energy by Minimising Belt Rolling . The LRR belt can achieve significant energy savings for pipe conveyors. Using the Kailin conveyor as an example based on the 3.2 million metric tons annual tonnage the current LRR belt will save about 4 million kWh per year compared to the conventional pipe belt.

How To Design Takp Travel For A Fabric Conveyor Belt
On a case to case basis it may be possible Using LRR reduces the belt tension and maybe belt rating but belt safety factor in general is kept the same. As a pipe conveyor belt can make sharper curves than troughed conveyor belts pipe conveyor belts are usually used to reduce the number of transfer points and land requirement.

In a belt conveyor flip Figure 1 upside down and we have a rubber belt indenting into the steel idler rolls that support it and the load it carries (Figure 2). Figure 2 As the belt rides over the rolls it is easy to visualize how the roll indentation into the rubber causes resistance to motion (Figure 3).
For conveyors where belt indentation is a major contributor to drag OCC recommends testing to confirm estimated values. It is not possible at this time for users to directly enter belt indentation testing results into Belt Analyst. If this is wanted contact OCC. See Also LRR
