What is the Requirement for Belt Conveyor Restart-up?

When the belt conveyor stops , restart-up belongs to overload start. Thus it requires belt conveyor equipped with a frequency converter in order to overload start. Here PK Machinery will summarize the requirement of belt conveyor restart-up.

Belt conveyor in the pick-up for overloading startup, motor output torque, which every support to overcome below the belt between the wheel and the roller shaft caused by static friction torque, also want to overcome the material on the belt tension caused by the downward drag torque.

Materials on the belt tension caused by the downward drag torque is constant.But the static friction force is much larger than the dynamic friction, making it in order to overcome the initial startup of the static friction torque than the normal run-time dynamic friction torque caused by the much larger.

The inverter must have the function of the large starting torque at low speed.Actually in the process of starting, as a result of the belt scale, each wheel is time order one by one according to the rotation, will not rotate at the same time.Even if the wheel rolling, because of low speed between roller and roller shaft lubrication is not good, will be very acerbity, the dynamic friction is unstable, so low starting torque has the certain fluctuation.

So this kind of big starting torque at low speed is the need to maintain a certain period of time, usually at least a few seconds.The length of the belt and the minimum speed startup, and scalability of the belt.Because of the low speed, and startup torque and speed fluctuation will be big.

How the Fixed Belt Conveyor Roller Classify?

Roller is used to support the conveyor belt and carry of the material, to ensure the stability of the conveyor belt.
In general, the fixed belt conveyor roller is the following:
1.Trough roller: it is also known as carrying roller which is used for carrying bulk material;
2.Parallel roller: parallel upper roller is used for carrying materials, parallel lower roller is to support the return branch of the conveyor belt;
3.Self-aligning roller: it includes taper aligning supporting roller and friction aligning roller which are mainly used for adjusting the belt deviation to avoid S-shaped, so as to ensure the stable operation of conveyor belt;
4.Impact roller: it is installed in the lower part of the conveyor belt, which can reduce the impact of the conveyor belt to extend the service life of the conveyor belt;
5.Return roller: it supports the conveyor belt of lower branch,including parallel type, V type, inverse V type,etc. V and inverse V type roller can reduce the conveying belt deviation possibilities;
6.Transition roller: it is installed between the drum and the first set of roller, which makes the conveying belt gradually turns from through shape into or flat shape and reduce additional stress of the conveying band edge turns to trough shape due to the expansion, at the same time,it can prevent the material spreading phenomenon of conveyor belt.
In addition, the comb type roller and screw roller, which can remove the sticky material on conveyor belt to keep the conveyor belt clean. 

Safety Cautions of Fixed Belt Conveyor

Safety Cautions of Fixed Belt Conveyor

In the process of daily use,many users may use the wrong way to operate the belt conveyor.It will not only result in conveyor damage, but also harm to the operating personnel. Please pay attention to the following safety operating methods in order to utilize the fixed belt conveyor better.

Before the fixed belt conveyor put into use,uses should attention the following aspects.

1.Install the fixed belt conveyor according  to the prescribed installation methods

2.Check the running part of the belt buckles and bearing device is normal, whether the protective equipment is complete

3.The temperature of the working environment and delivery of materials shall not exceed 50 ℃ and lower than -10 ℃

4.No pedestrians or take stand by the conveyor belt

5.Ensure the conveyor motor insulation is good

During the operation of belt conveyor,users can not ignore the following aspects.

1.No-load start the belt conveyor. Functioning rear can into the material.

2.When the conveyor is running the series, we should begin the discharge end, a sequence start. 

3.Be sure to stop into the material and then stop

4.Forbidden to pull the belt by hands,in order to avoid the accident

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.

Let's look at how the fixed belt conveyor transport raw material for cement.
