Ways to Maximize the Performance of Belt Conveyor

Ways to Maximize the Performance of Belt Conveyor

During application of belt conveyor, it is beneficial to reduce operating resistance by using high precision conveyor rollers and high performance belt. Revolving resistance of rollers and forward resistance of belt conveyor account for 50% main resistance in belt conveyor. If the belt conveyor length is more than 80m, main resistance will be influenced by device condition, friction coefficient related to real working condition, conveyor length, rotating quality in unit length of roller, belt quality, material property, etc.

Apart from above mentioned influential factor, we can refer to the following ways to maximize the performance of belt conveyor:

1.Reduce or adjust belt deviation;

2.Add lubricating oil to components of belt conveyor;

3.Clean up the sundries produced in transportation promptly;

4.Tension force of belt conveyor should be adjusted the best status;

5.Please add oil to conveyor pulley at fixed period to ensure smooth rotation;

6.It’s better to adopt vulcanized joint, though it costs too much money, it can keep a longer service life(especially suitable for fixed belt conveyor).

How to prolong lifespan of belt conveyor

How to prolong lifespan of belt conveyor

Quality of belt is the main reason to impact on belt conveyor lifespan, so it must purchase the belt with high quality. Meanwhile, it should make sure that sweeper is reliable to use so that there is no material on the return belt. Otherwise, materials adhered to return belt will be taken to the surface of drive pulley and bend pulley, then it will damage belt and reduce its lifespan.

There are some problems in the use of belt conveyors sometimes, to which require you to pay attention that you can greatly extend the service life of belt conveyor.

1. If there is the phenomenon of belt slipping on drive pulley, users should find the reasons and adjust it promptly.

2. Please always check the belt connectors, if there is local damage, please repair it or replace conveyors joints.

Please Focus on Belt Speed Selection and Principle of Belt Conveyor

Please Focus on Belt Speed Selection and Principle of Belt Conveyor

Do you know how to select suitable #belt speed? This article will analysis its selection and principle of #belt  #conveyor  .

As we all know, the most decisive factor of belt conveyor throughput is the belt speed, here we would like to introduce the selection method of belt conveyor belt speed: 

(1) If the conveying capacity of belt conveyor is large, belt width is wide, please select a high belt speed.

(2) If the material is easy to move with big granularity and strong grinding property, please select a low belt speed.

(3) If material conveying interval is long, please choose a high belt speed; If material conveying interval is short and the conveyor angle is big, please select a low belt speed.

(4) If there is large amount of dust during conveying, the belt speed would be 0.8 m/s ~ 1 m/s.

(5) If belt conveyor works with a discharging tripper, the belt speed should not be higher than 2.5 m/s.

(6) If belt conveyor conveys finished product items, the belt speed should be less than 1.25 m/s.

Belt speed selection principle of belt conveyor : the belt speed of belt conveyor is related to belt width, throughput, material size, material properties and conveyor angle. When belt conveyor transports upward and dip angle is large, the tape speed should be low; When belt conveyor transports downward, the belt speed should be much lower. Belt speed selection also should match the cooperated material discharging equipment type, when adopts plough type discharging machine, the belt speed should not exceed 3.15 m/s.
