Please Focus on the Installation Method of Portable Belt Conveyor

Please Focus on  the Installation Method of Portable Belt Conveyor 

As an efficient and convenient transportation equipment, mobile belt conveyor has played an important role in the process of conveying bulk material, lump material and other materials.

Upon receipt of inquiry Mobile belt machine, our engineers according to the different needs of customers, design different bandwidth and different lengths.
However, due to the packaging volume of mobile belt conveyor is too large, in order to facilitate transport, we generally will demolish the mobile belt conveyor before shipment.Therefore,when customer received the equipment,they need to disassemble the mobile belt conveyor again.
It should be noted that, during the installation process, the core of the belt conveyor is installed to install the rope and belts.Whether they install the rope and belts correctly will impact directly on the lifting capacity and operational capabilities when using belt.
In order to allow customers to better put into use, our engineers attached the following drawings to show the installation of wire rope and belt toward:

What Should You Pay Attention to About the Conveyor Belt with Large Angle?

Why you should pay attention to the belt conveyor with large angle? That almost because the heavily damaged by the belt which is under the overload.And then,this damaged will not only lead to the belt reversal,but cause more seriously accidient like belt broken,frame destroy.In order to avoid more damaged by the conveyor belt with large dip angle,it is necessary to learn the anti-reversal control methods.The following introduction would like to introduce the analysis detailedly.

Are you still using the capture device method to avoid this destory by the overload?You may find that it doesn't have a better real effect.Today we will show you a fresh way which you should pay attention so much.

With the anti-reversal control method,it’s better for you to adopt unidirectional rollers.

1.     When the belt goes up, the rollers will rotate accordingly

in this case, friction between upper belt and rollers is rolling friction.

2.     When the belt is breakage and upper belt goes downward slide, the rollers will not do reverse rotation

on this occasion, friction between upper belt and rollers is sliding friction. 

And then,in this way can it realize breaking.

How do I Convey the Gravel by Sidewall Belt Conveyor ?

Sidewall belt conveyor is continuous transporting equipment of loose bulk materials such as coke, coal, limestone, sand and gravel.Gravel is the loose bulk materials,which is composed of  unconsolidated rock fragments that have a general particle size range and include size classes from granule- to boulder-sized fragments. Gravel is categorized by the Udden-Went worth scale into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). One cubic yard of gravel typically weighs about 3000 pounds.

Gravel is an important commercial product, with a number of applications. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or tarmac; Russia alone has over 400,000 km (250,000 mi) of gravel roads. Both sand and small gravel are also important for the manufacture of concrete.When convey the material like gravel,it may use the belt conveyor.

How the belt conveyor can transport  the gravel?Here PK Machinery would like to introduce the advantages and features of sidewall belt conveyor as follows.

Features
   1.Long service life
   2.Reduced maintenance
   3.Low power consumption
   4.Reduced number of transfer points
   5.Quick installation and quiet running

Advantages

   1.Flexible transportation – can convey all kinds of bulk materials such as coal, ore, sand, fertilizer and grain in horizontal, oblique, vertical or other angle directions. 

   2.High tensile strength

   3.Increases belt capacity

   4.No spillage with steep angle conveying

   5.Decrease necessary conveyor footprint

   6.No transfer points- the belt are capable of turning at any angle right from feed hopper to discharge point

   7.Maximum utilization of space – able to convey material at angles up to 90 degree

   8.Decrease maintenance costs with fewer drive units and components

   9.Long lifespan

   10.Low power requirement – requiring low power to move loaded belts

   11.Quiet smooth running – as belt runs on rotating idlers, low resistance is achieved that in turn ensures quieter operations

It adopts high quality conveyor belt with corrugated sidewall and horizontal baffle. Sidewall belts are used to convey material up inclines. The sidewall increases the carrying capacity of the belt and prevents product from falling off the edges of the belt. Hot vulcanization provides a 5x greater adhesion between the belt and sidewall, eliminating the need for bolting the sidewall to the base belt. Greater adhesion also prevents the sidewall from lifting and separating from the base belt, extending the belt life.

Failure Analysis of Belt Conveyor Components

In the process of operation, failure of belt conveyor is inevitable, here PK Machinery will analyze the cause of belt conveyor failure.
1.Belt doesn’t rotate 
After start-up of the belt conveyor motor, the belt of drive pulley idles and slips, belt can’t rotate, this failure is caused by insufficient belt tension, improper adjustment of tension device, overlong length, overloading start-up, coal piled in the tail part of belt conveyor.
2. Belt is easy to break 
It is due to the large belt tension loose joint, poor quality of belt buckle, belt using for a long time, poor maintenance of belt, the solution is to tighten tension device, lower the tension ,change the new belt in time and strengthen the maintenance quality.
3. Reducer occurs abnormal sound.
The reason is due to the larger gap caused by serious wear of bearing and gear or screw is too loose, the solution is to replace the bearing, adjust the gap and repair or replace the whole reducer.
4.Reducer heats up too fast.
The reason is because of too much oil, poor heat dissipation performance, speed reducer is buried in coal pile, the solution is to adjust oil amount and remove the coal.

5.Reducer oil leakage.
The reason is due to the damage of sealing ring, the connecting surface of reducer is not uneven, the bolt is too loose, the solution is to replace the sealing ring, tighten the connecting surface and the bearing cap bolts.

 

6.Roller doesn’t rotate.
It is because of the damage of roller bearing, when coal powder enters into the roller sealing ring on both sides, it will be blocked and not rotate which makes the roller bend due to the large stress. The solution is replacement roller, reduce the height of discharging point and the landing point, or use the shock-proof roller at the landing point.

The Conveyor Belt Marketing Demand

What can we learn from the conveyor belt marketing?The report shows the expect of growth in Asia Pacific conveyor belting market.

According to a recent research by Future Market Insights,global demand for conveyor belts and the trend is anticipated to continue for a foreseeable future.

The report which covers the ten years of 2015-2025 said that Asia Pacific includes India and China whose industrial investments are among foremost factors driving demand for conveyor belt in the region.

Now let's look at the related characteristics of conveyor belt.
Conveyor Belt  is a friction drive conveyor transported materials continuously. Conveyor Belt  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.

Conveyor belt operating speed generally not more than 2.5 m/s. For large lump size, material with large abrasiveness and fixed unloading device should use low velocity. The relationship between driving pulley diameter and coating layer of conveyor belt, supporting of driving and bend pulley and also requirement for trough angle of idler roller should according to the design specification of conveyor belt, reasonable selection. Direction of feeding should along the operating direction of the conveyor belt, use chute in order to minimize the impact of material fall on receiving belt, reduce material’s free fall distance. The feeding section of conveyor belt should shortened the spacing of idler and use absorber idler as discharge section. The belt should use striker plate with moderately soft, to avoid the rigid striker plate will scrape the belt surface of conveyor belt.
In this marketing,we must change the ways to take part in the market.
