Conveyor belts is a composite product of rubber, fiber and metal, or a composite product of plastic and fabric, which is used to carry and transport materials in the belt conveyor belt. Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the conveying distance is short and the conveying capacity is small. Belt conveyor is widely used in agriculture, industrial and mining enterprises and transportation industry to transport all kinds of solid block and powder like materials or finished articles. The conveyor belt can be transported continuously, efficiently and with a large angle. The conveyor belt is safe to operate, easy to use, easy to maintain and low in freight. It can shorten the transportation distance, reduce the project cost and save manpower and material resources.
Why can conveyor belts be widely used in all walks of life instead of manpower, because conveyor belt has the advantage that manpower can not reach. The conveyors belt has high efficiency and less error, which can save human and material resources for the enterprise. Compared with the traditional human material transportation, conveyors belts has more obvious advantages. Next, Huayue rubber will introduce to you the advantages of conveyor belt
1、 The high efficiency of conveyors belt, conveyor belt is an efficient handling equipment, which can completely replace human handling in some enterprises, and bring more benefits to enterprises. Help enterprises create more value in a shorter time.
2、 The conveyor belt has high carrying capacity, which can carry heavy goods, and heavy goods which can not be carried by manpower. The conveyor belt can solve this problem well. Moreover, the handling is more durable and can work stably for a long time.
3、 Less error. Conveyor belt can reduce all kinds of errors and accidents in manual handling, only a small number of people are required to take care of it.
4、 The conveyor belt has high safety. For example, some inflammable and explosive materials are very unsafe to be carried by human. Even if there is a danger, the use of conveyor belt will not endanger people's health and safety. It is the necessity of the times and the gospel of the enterprise that the conveyor belt can replace the human transportation. It has brought a lot of fast and convenient production for enterprises and better service for people.
5、 Rubber conveyor belt is the main part of belt conveyor, which plays the role of carrying materials. It is widely used in metallurgy, building materials, docks, mines and other industries. Compared with other transportation methods, using conveyor belt as transportation carrier is safe, convenient and easy to maintain.
The physical properties of conveyor belt are different, but in normal use, there are many problems of idler conveyor belt. One of the problems we often encounter is that it's easy to slip. What's the reason for the conveyor belt to slip? It involves the knowledge of friction. We know that when the conveyor belt is rolling normally, its belt speed is generally not less than 95% of the rotation speed of the idler. If the friction between the idler and the conveyor belt is not enough to maintain the balance, the conveyor belt will slip away from the idler, which is called belt slip. Some people want to ask how the friction between the idler and the conveyor belt is so small that it is not enough to support the force. There are many factors involved.
As mentioned earlier, there are many factors that cause the insufficient friction between the conveyor belt and the idler. These factors are mainly: some are insufficient tension, some are insufficient load starting, and some are too small friction coefficient on the surface of the idler. For example, the roller often used, after a long time, the friction coefficient inside becomes larger and smoother, which is also an important performance of conveyor belt slip. If the discussion is more careful, let's first see why the tension between the conveyor belt and the idler is not enough? For example, the compactness of the two is too small to form an effective combination.
In engineering work, the conveyor belt bears too much conveying force and the object weight of the counterweight is too enough. If the length of the conveyor belt is long, it is also one of the reasons. The friction coefficient between idler and conveyor belt is not enough for other reasons, such as serious friction and wear on the surface of idler, some wet or oily liquid on the conveyor belt body, and the sticking of these materials on the surface of the belt body is also one of the difficulties.
There are essential differences between heat-resistant conveyor belt and normal conveyor belt in selection. The connection between the diameter of the driving drum and the cloth layer of the heat-resistant conveyor belt, the matching of the driving drum and the direction changing drum, and the demand for the groove angle of the idler shall be reasonably selected according to the planning rules of the conveyor. The feeding direction shall be along the operation direction of the conveyor belt. In order to reduce the impact of falling materials on the conveyor belt, chute shall be used to reduce the gap between falling materials. In the receiving section of the conveyor belt, the gap between rollers shall be shortened and buffer rollers shall be selected as the leakage material. The conveyor belt shall be used with soft and moderate baffle plate to avoid the baffle plate being too hard and scraping the belt surface of the conveyor belt. Avoid launching with load. If the conveyor belt deviates, it shall be corrected in a timely manner. Different types and standard layers of conveyor belt should not be used together, and the best way to use the joint is bonding. The type, structure, standard and number of layers of the conveyor belt shall be selected reasonably according to the operation conditions. The operation speed of the conveyor belt should not be more than 2.5m/s, and the materials with large block and abrasion and the unloading equipment with fixed pears should be selected as low as possible. When the conveyor is in use, if there is a lack of idler, it should be added and repaired in time; the idler is covered by materials, which makes the reversal ineffective, so as to avoid material leakage stuck between the roller and the belt. Pay attention to the smooth movement of the conveyor belting, but do not grease the conveyor belting. The heat-resistant conveyor belt shall not be blocked by the frame, pillar or block materials, and shall not be torn. If the conveyor belting is found to be damaged, the artificial cotton shall be used to repair in time to avoid widening.
When selecting the conveyor belt, the most suitable Belt should be selected not only depends on the thermal strain, but also depends on the chemical mechanical stress. The temperature of the transported material and the surface temperature of the belt are changed according to the composition, nature, surface structure, shape and particle size of the material. For example, when the temperature of the bulk material is 150 ℃ (coke or sinter ore) and the touch area of the belt is small, the surface temperature of the belt is changed It can be kept at 60 ~ 80 ℃. However, when transporting cement powder, the difference between the material temperature and the belt surface temperature is very small; the tropical endurance life is affected by the belt surface temperature appropriately and fiercely, and it affects the cover rubber falling block and the belt core delamination. Therefore, when selecting the belt, it is very important to think about the belt surface temperature, as well as the environment temperature, whether the belt can be fully cooled when it comes back; the belt speed and the base interval are worth noticing; thicker the cover is the important condition to ensure that the belt has a longer life. We advocate the thickness of the fabric core to cover the tropical zone: the upper cover 6~8mm and the lower cover 2~4mm(inc).
