How to Solve the Problem of deviation of belt conveyor

Belt deviation of belt conveyor is the most common troubles in operation. Key points to solve the problem are ensuring the precious size in installation and regular maintenance. As various reasons of deviation, we need to solve problems distinctively.

1. Adjust carrying idler group. When belt in middle section is deviation, can adjust the place of carrying idler group. The concrete way is that forward idler group to the side belt biased while other side backward. Move the lower part of idler left when belt running deviation upward when upper part downward.

2. Install spherical idler group. There are many types of spherical idler, such as intermediate shaft type, four link type, vertical roller type, etc. It is reasonable to install spherical idler for shorter belt or two-way running belt conveyor because shorter belt conveyor is easy deviation and uneasy to adjust. However, longer belt conveyor may as well not use this way as spherical idler may effect the service life of belt.

3. Adjust the positions of driving roller and bend roller. If belt is running deviation to the right side of driving roller, move bearing at right side forward. And same to the left side. Adjustment method of bend roller is opposite with driving roller. Adjust repeatedly to the ideal position and may well as install accurately before adjust the rollers.

4. Adjust take-up unit. Take-up unit adjustment is the very important part of deviation adjustment of belt conveyor. Two bend rollers at the upper side of heavy hammer take-up should perpendicular to belt length direction and vertical gravity to ensure its shaft center line horizontal. When use screw take-up or hydrocylinder take-up, two bearings of take-up roller should translate at the same time to ensure roller axis is vertical with longitudinal direction of belt conveyor.

The Role of Conveyor Belt Cleaning Device

The belt conveyor is often used to transport viscous materials, such as coal dust, mud, powder materials and etc.. Some of them will stick on the working surface of belt conveyor, which cannot be removed when discharged the materials. At this time, the adhesive material will then enter the return idler, the roller become dirty as attachment stick on it. Materials enter the roller casing, thereby increasing the radial and thrust load of bearing block, causing rapid wear of bearing. The materials deposit on the roller casing will tear the rubber surface of the belt conveyor, accelerate the wear out failure of belt conveyor. If sticky materials enter the tail bend pulley, it will stick on the surface of roller. The more the viscous materials stick on it, the greater the force of the sticky materials, which will result belt deviation and increase belt wear, leading to serious consequences.

The remaining material on the belt conveyor will increase the friction force on roller, sometimes it may cause the tear on the rubber surface of belt conveyor and also the layer of roller encapsulate. If the cleaning device can function well, it can prolong the service life of the roller, belt conveyor and etc.. This shows that the cleaning device has a significant effect on belt conveyor. In the process of operation, if you want to clean the sticky material on the tail bend pulley through anthropogenic removal, it often prone to serious bodily injury or death. Hence, in order to ensure the normal operation of the belt conveyor, the sticky material must be cleaned up by cleaning device before materials enter into the snub pulley.
