Belt Edges:
Roshan Belts are manufactured with various edges
|
|
Welded edges This is the most comon belt edges used in processing industries.viz Biscuits,confectionary, annealing plant where there is normal load on the conveyor.
Application: Used in Quenching, Frying |
|
|
Bent edges This Spiral coil edges are bent over the cross rod to give more flexibility and strength to the belt.
Application: Used in Quenching, Frying |
|
Chain EdgesThe edges of this belt is provided with rationally pitched chain at both sides, bolted or welded with reinforced rod provided through the belt. Chain Link
belt are used where there is tracking problem due to greasy and oily substance or if the load is to be carried in opposite direction to that of gravity This belt are also called as “Track Free” conveyor.
Application: Used in Quenching, Frying |
BeltWeaves:
Laminated Belt or R-Omni flex
Woven Wire Metal Mesh Belts
Belt with rod & chain arrangement
Flat Wire Belts
Chain Driven Belts |
Belt Specifications:
 Wire conveyor belts are specified by :
The number of spiral coils per foot of belt width (A)
The number of cross members per foot of belt length (B)
Diameter of spiral coil wires (C)
Diameter of cross rod wires (D)
Belt Selection and Operation
:
Selection of the
correct belt for elevated temperature application is as
complicated as it is important.The selection process includes : Alloy selection, Contaminants
considerations, Temperature considerations , Mesh selection, Consideration of the conveyor. Each
of these factors are interrelated, so no one item can be assessed by itself.
Once the belt is selected, belt life and performance maximization are the goals. Factors
affecting belt life and performance under operating conditions include : Installation and
break-in procedures, Carburization, Conveyor alignment and condition, Nitriding,
Loads and load concentrations, Preferential Oxidation, Operational conditions,
Contaminants, Mechanical damage. Some of these factors are inherent in the process,
and at best, can only be minimally contolled. Others are highly controllable.
