Conveyor Belt Mechanical Splicing vs Vulcanizing | Agg-Net

2  · Conveyor belt and belt splice damage will always be a fact of life in most bulk material handling applications. Consequently, operations and maintenance personnel should have a thorough understanding of the available splicing and repair alternatives, and how each method can affect the productivity and cost-effectiveness of operations.

Belt Tension

If standard belts are operated below 140°F, their materials of construction are not affected. However, at temperatures above 140°F, over-curing will occur and belt life will be shortened. Therefore, the use of standard V-belts above this temperature should be avoided. Often, adequate shielding between the heat source and belts can be provided.
