Type Introduction and Maintenance of Conveyor Belt Rollers

A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types ofconveyor systems. A belt conveyor system consists of two or more pulleys(sometimes referred to as drums), with an endless loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handlingsuch as those moving boxes along inside a factory and bulk material handlingsuch as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more.

Belt conveyor roller is an important part of belt conveyor. It accounts for a total cost of 35% of a belt conveyor, suffered more than 70% of the resistance. So the quality of roller is particularly important.

The role of roller is to support the belt conveyor and the weight of material. Roller must be flexible and reliable operation. Although the roller in the belt conveyor is a small part, structure is not complicated, it is not easy to produce high-quality roller. The conveyor rollers of our company are well accepted by the customers for their higher quality, reasonable price and good service.

The Carrying roller is usually equipped in the belt conveyor, which is widely used in coal mines, metallurgy, ports, construction site, power station, and chemical, food industries.

Today there are many types of rollers as follows:

1.Trough rollers
The standard tough angle of trough roller is 35 degrees, so most of conveyors use 35 degrees trough rollers and 35 degrees trough bend forward rollers.

2.Impact rollers
Impact roller angle includes 35 and 45 degrees, when using the canvas conveyor belt, only the 35 degrees tough impact roller can be selected. groove rollers. 45 degrees trough impact roller can be used in the section where the guide chute will not be affected by material impact .

3.Transition rollers
Transition roller is used for belt conveyor with large capacity, long distance and large conveyor belt tension.

4.Return rollers
Return roller is also called below parallel roller, it is also the most used one kind of the roller.

5.Self-aligning rollers

Self-aligning roller includes ordinary self-aligning roller, friction self-aligning roller and tapered self-aligning roller. cone-shape self-aligning roller. Self-aligning roller is applied to automatically correct excessive running deviation appeared in the process of operation to guarantee the normal work of belt conveyor.

6.Maintenance
Since rollers occupies large quantity of belt conveyor parts, so for belt conveyorrollers, maintenance is particularly important. During the process of using, please keep the belt conveyor roller working in a dry environment, change the damaged roller in time and keep the roller surface clean.

A high efficiency, good mobility Portable Belt Conveyor

What's the material will you transported, bag material or bulk material?Have you used the belt conveyor transport this material?Conveyor belts are primarily employed for carrying objects, from one point to another. The belts typically comprise two or more pulleys to rotate a belt in continuous circles.

The material to be transported in placed on the belt and is carried to the end point on the belt. Commonly, two pulleys are employed for functioning of one conveyor belt one of the pulleys is rotated and it drives the other pulley while it is rotating. The belts are generally used for transportation in close distances, generally within a building.

Conveyor belts may comprise one or multiple layers of materials such as rubber strapped around pulleys that rotate circularly and carry objects or materials along with the rotation. The pulleys are commonly called roller heads. Compounds of rubber are used in the production of belts; the compounds are plasticized to increase their efficiency.

The belt is treated with heat to improve friction. Belts and roller heads are coated to improve wear and tear resistance and friction depending on the end user application. The belts find application in several industries including transportation of goods and machinery in industrial applications such as automobiles, electronics, construction, aviation,. 

If you want to transport this materials,maybe the portable belt conveyor can meet your demands.DY Portable belt conveyor is lightweight continuous conveying equipment which has the features of high efficiency, good mobility, and convenient usage.And it is mostly applied to port, jetty, mining, warehouse, and construction site for moving bagged cargo and bulk materials.Is it?

Movable belt conveyor is divided into rise-and-fall and non rise-and-fall conveyors.It is a kind of machinery that can transfer the material continuously by friction drive.

According to different transport requirements, the transport system can be single belt conveyor or consist of several conveyors or be combined with other conveying equipments.It can be installed horizontally or aslant to meet the needs of different production lines.

Fixed Belt Conveyor Transport Raw Material for Cement

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum andlimestone.Cement is so fine that 1 pound of cement contains 150 billion grains.The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.

In the process of operation,Fixed Belt Conveyor is a friction drive conveyor transported materials continuously. Belt conveyor machine comprises the rack, conveyor belt, pulley, rollers, tensioning devices, driving unit and other components. It not only conveys material, but also can cooperate with various industrial equipments to form a rhythmic transport line.

Expect cement,long distance belt conveyor can transport bulk materials or bagged goods, such as stone, sand, coal, concrete, gravel, fertilizer, mineral ore, limestone, coke, sawdust, wood chip, bulk material, grain, corn flakes, carbon black, component/part, etc.

The video--fixed belt conveyor transport raw material for cement

The introduction and application of tension device

 Belt conveyor is a transport machine that is driven by friction and it can transport materials continuously. Belt conveyor needs tension force in order to ensure the normal and stable operation of conveyor and meet the friction driving force between the driving drum and the belt. It is very important to choose the proper tension device when we design the belt conveyor.

Functions

1.Tension device can make the belt conveyor have enough initial tension force so that can ensure the necessary friction between belt and driving drum.It also can reserve friction to meet the requirements of friction drive of transmission drum.

2.Tension device can ensure the tension force of minimum tension point in order to satisfy the pendulous restriction conditions of conveying belt so that can make sure of the normal running of conveyor.

3.To provide the necessary route for conveyor belt joint.

Detailed rules and regulations of operational approaches

      When we turn off belt conveyor, the stored energy of conveying belt will release rapidly; and then it will damage its mechanical components and conveying belt itself, especially in the dip angle of belt conveyor and the tension device. When the belt conveyor brakes suddenly, the speed of driving drum will decrease rapidly and the linear displacement will less than the displacement of upstream drum. This characteristics will decrease the mechanical stress of upstream conveying belt and the deformation of belt will smaller, while the mechanical stress of downstream conveying belt will increase as well as deformation. That is to say,when the speed of transmission drum suddenly reduces, the returning conveying belt under the transmission drum caused by the mechanical stress of belt will be strained while returning conveying belt and upward conveying belt below the transmission drum will be relaxed because of the inertia of mechanical equipment. Thus, tension device of conveying belt should pay much attention to its deformation and brake the displacement of upstream position.

How to deal with the feed casting of belt conveyor

    It is a common problem that belt conveyor will appear the phenomenon of feed casting.And the reason is multi-aspect.The most important thing is that we should emphasis on its maintenance in daily life.

    1.Feed casting in the transferring point.This kind of situation will be happened in the hopper and guide chute.If belt conveyor is overload,it will result in the damage of keep-off rubber apron board. We can solve this problem by controlling the conveying capacity and strengthening the maintenance.

    2.There is feed casting when concave section of belt conveyor suspends in midair.The reason why concave section of belt conveyor suspends is that curvature radius is smaller. At this time, the situation that belt conveyor becomes groove will change. Because belt has departed trough roller unit, the groove angle becomes smaller that will result in the phenomenon of feed casting. Therefore, we should adopt the larger curvature radius as far as possible in the design stage to avoid happening this kind of situation. 

    3.When the belt is off tracking, it will appear the phenomenon of feed casting.The reason is that the height of two edges changes when the belt is running.Thus,one side of belt is high while the other is low. And the n the material will drop out from the lower side. We can adjust the belt running deviation to solve it.

Two-way Pull Cord Switch of Belt Conveyor Protection Devices

The two-way cord switch adopts the world’s leading dual bearing transmission structure in order to avoid the friction exists on drive shaft directly when the s pull cord switch is switched on, causing the increasing gap, improper seal or stuck phenomenon, which will prolong the life-span of pull cord switch. Precise painting applied on the surface of two-way pull cord switch of belt conveyor protection devices which is not easily to fall off. The driving shaft is made of stainless steel material with high intensity, the surface of shaft is smooth. The lever is made precisely to avoid the welding. Besides, the bronze cushion is built internally which makes smooth surface of lever and higher intensity. This product has several advantages, which are longer life-span, flexible, practical ,safe and reliable operation, easier maintenance and so on.  

The Development Trend of Belt Conveyor

1. Larger scale
It includes several aspects, such as large transmission capacity and single equipment with long length .Now the world's longest length of hydraulic conveying equipment is more than four hundred kilometers, the longest length of belt conveyor is almost 15 km, and there is also a belt conveyor which can connect two cities together. The world's major developed countries are also researching and studying conveyors with long distance and large capacity of continuous conveying ability structure.

2.Higher performance and better functions
Working in the extreme temperature environment, or the working environment which is corrosive and radioactive, and the belt conveyor can carry inflammable,explosive,high temperature and viscous material.

3. Enable the conveyor to meet the requirements of the automatic control.

4. Reduce the consumption of energy to the greatest extent, calculation standards will be based on 1 ton materials transfer the energy dissipations of 1 km, this is one of the most important development trend in the future.

5.Reduce pollution of belt conveyor during operation to reach the goal of protecting the ecological environment.

PK Machinery company is also on the way to this future trend, we offer belt conveyor, bucket elevators, screw conveyor, scraper conveyor and vibrating screen etc. With abundant engineering design experience, professional technical ability and strict fabricating specification, PK Machinery will be the future global leader of mining machinery industry!
