Conveyor Belts
Conveyor Belts
We fabricate rubber conveyor belts in our own production facility using state-of-the-art equipment. Our experienced team receives continuous education and training through NIBA (The Belting Association) to learn the latest advancements in splicing and fabrication. We have the capabilities to fabricate and install conveyor belting.

Conveyor Belt Components
Conveyor belts are generally composed of three main components:
- Carcass
- Skims
- Covers
Carcass
The reinforcement usually found on the inside of a conveyor belt is normally referred to as the carcass. In a sense, the carcass is the conveyor belt since it must:
- Provide the tensile strength
- Absorb the impact of the impinging material being loaded onto the conveyor belt
- Provide the bulk and lateral stiffness required for the load support
- Provide adequate strength for proper splice holding
Skims
- The rubber, PVC or urethane between plies
- Important contributor to internal belt adhesions, impact resistance, and play a significant role in determining belt “load support” and “troughability”
- Improper or marginal skims lead to ply separation and or idler junction failure
Covers
Used in belt construction to protect the carcass and if possible extend service life. Covers do provide the finished belt with a wide variety of desirable properties including:
- Texture
- Cleanability
- Chemical Resistant

Corrective Action
- Replacement of failed components
- Lubrication
- Clean up or house keeping
- Record action taken to gauge progress
General Tracking / Training Procedures
- Tracking is the process of adjusting idlers, pulleys and loading conditions in a manner that corrects off running
- Tracking should begin on the return side near the head pulley and move toward the tail
- Track the belt empty at first and then loaded
- Make adjustments preceding the region of trouble
- Permit the conveyor to make several revolutions
- If over correction has occurred, move back the same idler
- If the belt runs to one side at a particular point on the conveyor, the cause is probably an alignment problem preceding the trouble area
FAQs
Q: What is proper minimum belt tension on a conveyor belt?
A: Proper minimum belt tension is the required tension necessary for the belt conveyor (or belt elevator system) to operate properly for its intended application and in its current environment.
-
-
- Minimum belt tension is great enough so that the belt conforms to the crown on any crowned pulley.
- Minimum belt tension is great enough so that the belt does not slip in relation to the drive pulley’s standard conditions, as well as demands.
-
Q: What are the top conveyor belt tracking problems?
A: There are eight common conveyor belt tracking problems to be aware of.
-
-
- Belt Camber
- Skew (Bow)
- Too low belt tension
- Failure to properly square belt ends
- Poor installation of mechanical fasteners
- Improperly executed belt splice or vulcanization
- Structural defect or maladjustment in the conveyance system
- Material Build-up
