Three methods belt conveyor turning design

We know that the turning conveyor belt used in the mining industry, chemical industry, metallurgy and other industries the most widely used, in most cases not linear conveyor type arrangement, but with a certain degree of bending, intermediate involves a variety of devices supporting each other, and therefore We need to consider the case when the user to use the site layout design of conveyors, need to turn portions given more consideration in the design and production in order to meet the requirements of users.

Turn belt conveyor design process is not often encountered in this case the same straight line, then often turn to consider the design of conveyor equipment and thus reduce duplication of investment, the impact of economic, transport efficiency and reliability Off health problems. Level turn the system power supply design and control system more focused, canceled the intermediate transfer discharge height, reducing unnecessary energy consumption, so as to achieve the finished material using a belt conveyor transport processes, effectively reducing capital investment and cost increases .
Common turning design two forms, namely forcibly guided turn and to turn natural variability, forcibly guided turn as we say Belt Conveyor and set up a special unit to achieve change at the turn of the change of direction. Natural variability to enable the conveyor belt by turning the mechanical laws of natural bending operation. Horizontal curved conveyor belong to this type, it is the ordinary conveyor belt, after turning radius is calculated, and based on this radius are arranged along the conveying line its roller group, but without conveyor can run at its curved run side.
Conveyor natural variability in general need to be taken to achieve the three methods, namely, the basic measures, additional measures and emergency measures to turn. Basic methods:
1. Make the roller turn at a certain angle mounting support, increasing a groove angle. At the same time as turning into a groove angle changes, so that the corresponding rack, roller seat or connection is subject to change.
2. constitute the inner curve elevation angle. Conveyor curve on the inside edge of the corner formed called inner curve, while the other side is called the outer curve. Since the inner curve elevation angle with the horizontal axis of the intermediate roller, said inner curve elevation angle, which aims to reduce the turning radius, the easy-to-achieve a smooth turn, of course, the greater turning radius make smaller, but over the General Assembly to make delivery Scroll to the outside cause material spilled material, as shown below. Return to adopt a single branch roller group, between the two return idlers belt above the pressure roller, in order to increase the lateral friction roller to the conveyor belt, can reduce backhaul branch determined turning radius.
Commonly used emergency measures are set side vertical roll, that is, inside and outside corner of the conveyor belt is set upright stick, belt deviation limit. Such measures often play a role, it will shorten the life of the conveyor belt. In companies use turning turning conveyor belt in the form of common is the use of highly heightening turn outside, so that the material spilled during transport due to the probability of the occurrence of the role of centrifugal force is reduced, while the enterprise can help companies reduce production the input device.
