Conveyor Rollers
There are two basic types of rollers used in conveyors. One is the load-bearing roller, which supports the weight of the material placed on the conveyor and helps to move it. These have to be selected mainly according to the weight that is to be carried.
The other type is the ‘return’ or ‘lower’ Conveyor Roller. Some of these have pointed rubber rings in the center and flat ones at the ends. The pointed rings break up the remains of carried material sticking to the belt. The flat rings protect the edges of the belt and facilitate its smooth return so that the loading can be continuous. They also prevent the belt from migrating beyond the tolerance limits. The return rollers can be equipped to clean themselves. The automatic cleaning of the conveyor belt and the rollers reduces the maintenance cost considerably.
Conveyor Rollers are normally manufactured from mild steel, stainless steel, PVC or aluminum. There are different types to suit for specific uses. Food processing industry uses stainless steel or PVC rollers. There are specially designed rollers that can spray water to wash the material being carried. For conveyor bends, tapered rollers are used. Some manufacturers strive to reduce noise to the levels recommended by the Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor, by improving the design.
Another variety used in conveyors is the impact roller. This is a support roller covered with shock absorbing rubber rings and is used mainly in systems moving heavy materials. It is fitted at the loading points to reduce the impact of the materials falling on to the conveyor belt. It may be motorized or gravity operated.
The move on bearings. Pre-lubricated bearings that are supplied by some manufacturers can minimize maintenance cost to a great extent. Also contributing to the operating cost reduction are high-tech internal motors to drive the rollers.
The Perfect Conveyor Monitoring System
When it comes to preventive maintenance for your conveyor belt system, then apart from a conveyor belt lubricating system, you also need a conveyor monitoring system.
conveyor monitoring system
A conveyor monitoring system will combine predictive maintenance with preventive measures to give you maximum effectiveness and minimum downtime on your conveyor belt system.
Have you ever calculated how much even a minute of downtime can really cost you? If you haven’t then it is time you did it. It will prompt you to invest in a quality conveyor monitoring Sidewall Conveyor Belt.
Today, there are several companies that offer monitoring systems. But which one of the lot is most suited for you?
Features to look for
Most conveyor monitoring systems will provide you with real time information about chain speed, drive amps, drive hours, air take up pressure, chain wear etc.
However, it will definitely help you if the system uses a graphical interface rather than a purely technical one. For example, if you can see chain wears in a standard graphical interface of every ten foot section or even link by link, then it would be a great advantage.
Look for parameter alarm and mail notification systems which notify you before the problem occurs.
Another feature that most people want in their conveyor monitoring system is the chain wear indicator. Just as a particular section starts to get worn out, it will indicate you so that it can be replaced before it fails completely.
The price factor
While a quality conveyor monitoring system when combined with a lubrication system might cost you in the start, this cost will be totally justified in the long run.
You will save up considerably on downtime costs and even on replacing links of chains rather than huge sections of the belt.

The bars are made from wood and the metal is cast iron. The cast iron is best in black for a time-honoured look, but there are a few other shades which may tone in better with your décor.
