Conveyed material

The element to start with when choosing conveyor rollers is the conveyed material which is strictly related to the area of application. The dimensions (length, width and height), weight and quantity of the transported material, as well as the rolling friction between it and the roller, determine conveyor rollers specifications including their length, diameter and load capacity. In bulk handling applications, these details also define the type and arrangement of belt conveyor idlers: each troughing sets is a combination of rollers positioned into a suitable fixed support frame with a specific function. Also, the texture of the conveyed material can influence the choice requiring sometimes abrasion and corrosion resistant rollers for conveyor. The physical features of the material are also a determining factor in calculating the type conveyor, conveyor speed and power drive requirements.

Environmental conditions

Another intrinsic aspect of each application field refers to environmental conditions which may require an adequate protection against any form of wear in rollers for conveyor. Open-air workplaces typical of bulk handling applications are exposed to any atmospheric condition, low and high temperatures and, in certain climates, to a large imbalance between day and night. Moreover, such applications deal with materials having a particularly abrasive and corrosive texture. Also, in indoor facilities unit handling conveyors may be required to work under critical operational conditions like the presence of dust, dirt, water, humidity and other corrosive elements, as well as specific regulations like food and beverage industry where strictly hygiene standards must be complied.

Conveying requirements

When selecting rollers for conveyor, it would be reasonable to determine the area the handling system is supposed to cover and consider whether a horizontal, inclined or curved transportation is required. Of course, such details lead to the use of a certain type of conveyor rollers in both unit and bulk handling applications. Among the most common conveying requirements there&#;s also accumulation option, even if this is more typical in unit handling applications. Manufacturing, packaging and logistic facilities needing to hold or stop items temporarily along the line have to consider this aspect because there are specifically designed rollers for conveyor to fulfill this duty.

Quality of conveyor rollers

Last but not least, looking for the highest quality of rollers for conveyor is hands down essential in the decision-making process.
