Conveyor belt load carrying capacity such as width, speed, tonnage inclination angle are important things that should be considered when buying a conveyor belt. The most important task of any conveyor is to transfer materials from one point to another. Without a doubt, the conveyor belt must have the ability to stretch these materials.
In this article, from the website of Rehavaran Sanat Qoms, we will discuss the load carrying capacity of the conveyor belt. The mentioned materials also affect the price of the conveyor belt. So read this article carefully so that you can make a correct and practical choice.
Different materials have different characteristics. These characteristics, such as moisture density, adhesion, abrasion, chemical corrosion, material temperature, as well as the size and shape of lumps and the ratio of the percentage of lumps in the material, are effective in the width of the belt’s speed and load carrying capacity.
The first effect of these features is when feeding the material on the belt. Different materials with special characteristics when filled on the belt form different angles to the horizon. We define these angles below.
The angle of relaxation of the load is the angle that the load makes with the horizon after being fed and placed on the belt. Regarding the overhead angle, when the load is placed on the belt, due to the movement of the belt, the angle of relaxation of the load becomes smaller until it remains constant.
The angle that the load makes with the horizon during transportation is called overhead angle. Usually, the overhead angle is between 5 and 15 degrees smaller than the angle of relaxation of the load.

Conveyor belt width
In general, at a certain speed, the width of the conveyor belt and its capacity increase or decrease together. Choosing the right width for the conveyor belt depends on the size of the lumps and the percentage of lumps in the material.
Conveyor belt load carrying capacity
The load carrying capacity of the conveyor belt is one of the important factors in choosing a conveyor belt, which is related to various parameters such as the speed of the conveyor belt and the width of the conveyor belt. A change in each of these parameters will cause a change in the carrying capacity of the conveyor belt and will affect the execution process of these devices and their work efficiency. Of course, the capacity of the conveyor itself depends on various factors, such as the type of materials to be transported, the size and dimensions of the materials, the distance of transmission, the installation space, etc., each of which will affect the speed of the conveyor and its width. In addition, any factor that causes a change in the capacity of conveyors also affects its durability and useful life.
Before choosing the load carrying capacity of the conveyor belt, it is necessary to pay attention to the amount of initial capital, the amount of energy consumed, maintenance costs, etc. in order to prepare a device suitable for work needs and with high durability and longevity. Due to the high importance of this issue in working with conveyor belts, in this article we intend to discuss issues such as the load capacity of the conveyor belt according to the width of the belt, factors affecting the determination of belt width, factors affecting belt speed, width imbalance, The speed and capacity of the conveyor belt and the problems caused by it, and finally the factors affecting the carrying capacity of the conveyor belt, let’s examine the carrying capacity of the conveyor belt, which we hope will be of interest and use to you.

Conveyor load carrying capacity according to belt width
The loading capacity of conveyor belts in different working conditions is always less than the maximum capacity considered for these devices. However, the power of the conveyor belt is always calculated based on one hundred percent of its theoretical capacity so that it can work under the influence of unusual loads. Assuming a fixed and specific speed for an execution process, as the width of the belt increases, the carrying capacity of the conveyor belt will also increase. Among other factors that can affect the load carrying capacity of the conveyor belt in these conditions are the slope of the side rolls and the charging angle, which cause a change in the capacity of this device.
To calculate the carrying capacity of the conveyor belt, first, it is necessary to measure the nominal cross-sectional area of the materials that are moved on the conveyor belt, which is done in a normal plane and relative to the conveyor belt. As the movement of materials is carried out on an inclined conveyor belt, it is necessary to measure the materials according to a vertical plane and with an additional load angle. Now, if the load to be moved on the belt is assumed to be uniform, the carrying capacity of the conveyor belt can be determined from the cross-sectional area of the load. Also, by assuming 80% of the capacity for the conveyor belt, in calculating the speed and width of the belt, the possibility of leakage and improper loading of materials can also be considered.
Factors affecting the width of the belt in the load carrying capacity of the conveyor belt
Various factors can affect the width of the conveyor belt, including the size and dimensions of the part to be moved. On the other hand, there is a specific relationship between the width of the conveyor belt in inches and the size of the part, based on which the width of the conveyor belt can be determined according to the dimensions of the part. Standard conveyor belts, whose width can be calculated using this relationship, are available as 18, 24, 30 to 96 inches, and 108, 120 and even larger widths can also be designed for customized conveyor belts. .
Of course, it should be noted that at a certain speed, as the width of the belt increases, the carrying capacity of the conveyor also increases. In such a case, it is necessary to adjust the width of the belts according to the size of the parts that are supposed to be moved on them. Of course, the width of the belts should be designed in such a way that it has enough width so that the parts do not come close to the edge of the belt during handling; Because this problem can cause disruption in the process of moving parts. Among the other factors that need to be considered in determining the width of the belt and ultimately the load carrying capacity of the conveyor belt, we can mention the effect of the load above the permissible limit, the high speed of the belt, the leakage of materials and the effect of dust on the performance of the belts.

Factors affecting belt speed
There are various factors that can affect the speed of the conveyor belt, including the characteristics and specifications of the material to be moved. Belt width, belt tension, load carrying capacity of the conveyor belt and unloading and loading equipment are other factors that can affect the speed of the conveyor belt. It should be noted that with the increase in the speed of the belt, the width of this section of the conveyor belt will decrease along with its tension, which will reduce the costs and initial investment in setting up these devices.
Before increasing the conveyor speed, it is necessary to pay attention to a series of factors in this field; For example, it should be determined whether the conveyor belt device has enough tolerance against the transverse vibrations of the belt or the noise level created or not. If the conveyor does not have enough resistance against the conditions, its speed should not be changed. Of course, there are a series of considerations for the minimum speed of the conveyor, which we will examine in the rest of this section.
First, in moving powdery materials, in order to reduce the possibility of creating dust in the transportation of these materials, it is necessary to move them at a low speed. Of course, the importance of this issue is greater in loading and unloading areas than in other areas. Fragile materials are other materials whose handling process, especially in the loading and unloading areas, should be done at a low speed to avoid the possibility of these materials breaking. Also, materials with sharp edges are other materials that should be moved at a low speed so that the sharp structure of these materials does not damage the surface of the belt.
Imbalance of speed, width and carrying capacity of the conveyor belt and its problems
Since the load carrying capacity of the conveyor belt is related to the speed of the belt and its width, the imbalance between them can be associated with problems that we will examine in this section. First of all, it should be noted that these problems occur in two natural and unavoidable ways. Natural problems are problems that usually occur in conveyors and their occurrence does not have much effect on the performance of these devices. But unavoidable problems can have an adverse effect on the performance of conveyors on the one hand, and on the other hand, these problems are inevitable, as their title suggests, and their effects on conveyors can only be controlled.
Of course, to control these problems, suitable designs for conveyors can be used. Among the problems that may occur in these conveyors due to the imbalance of the load carrying capacity of the conveyor belt with the speed and width of the belt can be the failure of these devices due to impact, the problems caused in this equipment due to getting stuck. Materials, damage of the belt edges in the form of one-sided or two-sided wear, delamination of the conveyor belt due to chemicals, humidity and low diameter of the belt, erosion of the upper part of the belt and tearing of the belt due to hitting external objects. With a series of preventive measures and basic repairs in this field, the problems caused by this imbalance can be minimized.

Factors affecting the carrying capacity of conveyor belts
There are various factors that can affect the load carrying capacity of the conveyor belt, the most important of which are the loads caused by spilled materials, live loads in ladders and corridors, the load caused by fork chutes, and the load caused by belt tension. , expansion loads and mechanical loads mentioned.
Loads caused by spilled materials and its effect on the load carrying capacity of conveyor belts
During the movement of the conveyor belt and its transfer process, some of the materials on the belt may leak to other parts of the conveyor structure, such as corridors, ducts, etc., which causes additional weight and load in the conveyor structure. For this reason, this load must be taken into account when calculating the carrying capacity of the conveyor belt.
Live loads in ladders and corridors and its effect on conveyor belt capacity
The live load on the conveyor belt is one of the other loads that must be taken into account when determining the carrying capacity of the conveyor belt. In many conveyors, corridors and ladders are used for the access of support agents to different parts of this equipment, the presence of these people increases the forces on the structure of the conveyor.

The load caused by the fork chute and its effect on the load carrying capacity of the conveyor belt
Examining the loads caused by the fork chute and including it in the load carrying capacity of the conveyor belt will be of great importance in the design of these devices. The variable characteristics of materials and mechanical failures are among the factors that cause the forks of the chutes, and not paying attention to them will be associated with serious damage to the conveyor belt.
Load caused by belt tension and its effect on conveyor belt capacity
As you know, the belts used in conveyors consist of a continuous ring made of rubber, which can withstand certain forces, which are called belt tension. This force depends on the amount of load on the belt and the driving force required for its movement, which must be included in the load carrying capacity of the conveyor belt.
Expansion loads and their effect on the load carrying capacity of the conveyor belt
Expansion loads are other loads that can affect the load carrying capacity of the conveyor belt. Since steel parts are used in the installation and operation of these devices and these parts expand under the influence of environmental conditions, it is necessary to include this factor in the calculation of the conveyor belt capacity.

Dynamic loads and their effect on the load carrying capacity of the conveyor belt
Although the design of the conveyor belt system is based on static load, these devices are also exposed to dynamic loads in addition to these loads. For this reason, when calculating the carrying capacity of the conveyor belt, these dynamic loads should be identified and their effects on the capacity of these devices should be taken into account.
