Type and Function of Fixed Belt Conveyor Roller

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. 

Follow the Right Operation of Fixed Belt Conveyor, Otherwise Accident will Occur

1.Fixed belt conveyor should be fixed in accordance with the specified installation methods on the foundation;
2.Before start-up ,please check all the moving parts of belt conveyor, such as if belt buckles and bearing device is normal, if the protective device is complete, if the belt tensioning condition is adjusted properly before start-up;
3. Fixed belt conveyor should no-load start up, only when operation is normal, can you feed the material, feed material before starting up the conveyor is not allowed;
4. when units of belt conveyor operate in series, please start from the discharged end in order, only when the operation is normal ,can you feed the material;

 

5. When belt deviation appeared in the operation of the belt conveyor, please stop the conveyor and adjust timely, so as not to wear edges and increase the load;
6. The work environment and material temperature should not be higher than 50℃ and lower than -10 ℃;
7. The conveyor must not convey people, and people is not allowed to stand under the conveyor;
8. Stop feeding material before stopping the conveyor, only after stored materials are discharged completely you can stop the conveyor;
9. Belt conveyor motor must be in good insulation;
10.Do not use your hand to pull the belt in order to avoid accidents when belt slips. 

The Features of the Fixed Belt Conveyor

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.

Belt conveyor is composed by two endpoint pulleys and a closed conveyor belt.  The pulley that drives conveyor belt rotating is called drive pulley or transmission drum; the other one–only used to change conveyor belt movement direction–is called bend pulley. Drive pulley is driven by the motor through reducer, and conveyor belt dragging relies on the friction drag between the drive pulley and the conveyor belt. The drive pulleys are generally installed at the discharge end in order to increase traction and be easy to drag. Material is fed on the feed-side and landed on the rotating conveyor belt, then rely on the conveyor belt friction to be delivered to discharge end.
Especially for the long distance belt conveyor can transport bulk materials or bagged goods, such as stone, sand, coal, concrete, cement, gravel, fertilizer, mineral ore, limestone, coke, sawdust, wood chip, bulk material, grain, corn flakes, carbon black, component/part, etc.

The Features and Advantages are as follows:
Features:
1) Long distance
2) Easy maintenance 
3) Steady operation
4) Convenient loading and unloading
5) Wide applications

Advantages:

The advantages of belt conveyor are 

   1.Large conveying capacity

   2.Long conveying distance

   3.Low horsepower compared with other types of conveyor

   4.Low cost of operating and maintenance

   5.Stable performance and reliable operation

   6.High universality and easy maintenance

   7.Labour saving

   8.No product degradation during conveying process

   9.Conveyor can have changes in elevation (horizontal, inclined or combination)

   10.Weight belt section can be added for continuous product weighing

   11.Belt conveyors can pivot at one end allowing the discharge to be moved over an arc (radial stacking).

belt conveyor for raw material in cement plant

Fixed/ stationary/ long distance/ overland/ heavy duty belt conveyor is continuous material handling equipment for loading and unloading material horizontally or aslant such as bulk material, lump material, and package goods.
Fixed conveyor belt consists of transmission device, frame, conveyor belt, pulleys, rollers, tensioning device, sweepers, hopper, gathering sill, etc.
Stationary conveyor belt is widely used in mining, metallurgy, coal, power plant, port, etc.
