Conveyor equipment is therefore required to be robust and reliable to ensure the highest efficiency under a variety of different conditions. Choosing a dependable conveyor roller is an important step to ensure an efficient conveyor system. But choosing the right one for your application can be a confusing task. In this post, we explain the different types of rollers used in conveyors and some of their benefits. But before that, let’s explore the characteristics of a high-quality conveyor roller. There are many conveyor roller manufacturers in the market but only a handful are experts at what they do. When you need a conveyor roller, make sure you choose a high-quality product with all the right qualities such as: It is important the roller adheres to international standards and is manufactured using quality processes to ensure you receive a high-quality product. The conveyor roller must be belt-friendly to reduce risk to conveyor belt damage. For the chosen application, the conveyor roller must be tough and durable for long life. For this, it is important to make sure the chosen roller is appropriate for the product specifications, transfer requirements, and service environment. Operational noise is an important factor to consider, especially in closed environments such as underground mines. Low noise keeps disturbance to surroundings under control and promotes worker well-being. Vibration usually occurs due to a loose connection between the roller and frame. Increased vibration causes high noise and reduces roller life due to fluctuating loads. Good conveyor rollers are fitted with precision bearings that are self-lubricating. Attention must be paid to bearing choice, manufacturing methods, and sealing arrangements for minimal vibration. We touched briefly upon the different qualities to look for in a conveyor roller. But by their very nature, some rollers will be better than others at certain features. Having pioneered the development of conveyor idlers in the global mining industry, PROK manufacture conveyor rollers with an emphasis on reliability and performance.

What Is an Idler Roller
Idler rollers are cylindrical parts used in conveyor belts. Pulleys and idler rollers are very similar. Generally, idlers are mainly used to support the conveyor belt, but there are also some idlers that can be used to transport goods.
Generally, conveyor idlers are used to move the belt and help drive the belt system. The idler rollers can also provide resistance within the belt and pulley structure. Some types of conveyor idlers may have the function of belt tensioner. When being moved, these idler rollers can change the tension on the belt of the conveyor.
As an important part of many industrial equipment and conveyor systems, the conveyor roller has the following types: in-line idler, inset roller and offset roller, and return idler. The construction methods of in-line idler roller, inset roller and offset roller are special so that the idlers can accommodate the conveyor belt according to the best factors. The return idler roller is often used to drive the reverse moving belt. They can help control the drive and functions that contribute to the conveyor belt as well as the return belt, such as the width or tension between the top belt and the return belt.
There are some specific types of conveyor idler that consist of several rollers, where each part of the idler roller is connected to the belt at different points to keep the belt operating correctly and well. Some idlers have adjustment handles to help the belt move correctly. All these show the versatility of the idler structure and ensure the normal operation of the industrial conveying system.
