Pickup, transfer and discharge conveyor belts are specified for the machine and the material being milled. Send the machine details and an existing belt reference.
Road-profiling machine and discharge conveyor in the workshop.
Base belt and cleat specification
Cleat height and pitch, clear edge widths, finished length and the joint all need to match. The same machine may use different belt constructions in different conveyor positions.
Select the reinforcement for the tensions and conveyor geometry. Select the covers for the material and the way the belt is wearing. Check the splice as part of the same specification.
Selection area
What to confirm
Fabric / steel cord
Reinforcement for the conveyor tension, geometry and joint design.
Solid woven
Integrated woven construction, cover formulation and joint requirements.
PU / PVC
Surface and backing, product handling, cleaning and machine arrangement.
Chevron / cleated
Pattern, base belt and the full inclined or machine conveyor path.
Specialty
The existing design, sample and operating requirements.
Belt wear and failure history
Record whether the present belt is wearing through its cover, splitting at an edge, separating between plies, losing cord adhesion or failing at a splice. A thicker cover will not correct a damaged structure, off-centre loading or a pulley that is too small.
Belt strength and working tension
The belt designation describes nominal strength. The working tension permitted on the conveyor also depends on the selected splice, operating conditions and design basis. Starting and braking loads need checking as well as normal running tension.
Belt-cover damage recorded during an inspection.
REPLACEMENT SPECIFICATION
Belt damage assessment
Cover wear, cuts, edge damage, exposed reinforcement and splice failures need different checks. Send the wear pattern and service history with the existing belt designation.
Confirm the loading and mechanical condition before changing the belt specification.
