Suggestions on Lubricating Points and System of Belt Conveyor

As we all know, regular maintenance and proper maintaining methods is essential in the daily operation of the belt conveyor.  Poor maneuverability would appear if the equipment has been used for long time, therefore we need to clean and lubricate the conveyor. Here our experts share some suggestions on the Lubricating points and methods with you.
  1.Lubricating Points
The lubricating points contains motor bearings, roller bearings, shaft sleeve bearings, bearing, gear reducer, the roller bearing and so on.
Roller is the most commonly used rotating parts of the belt conveyor, its quality and service life has a great influence on the belt conveyor running efficiency and reliability. The roller is equipped with bearing. Due to the gear reducer, its structure is relatively concentrated, with many parts needed lubrication, such as bearing pedestal, bearing gear and the meshing gear. In contrast, the structure of the roller bearing and motor bearings is relatively dispersed, especially the belt conveyor with long conveying distance. Each part is singly equipped with lubricating device.
2.Lubricating system
  •  Manual lubrication system
The manual cleaning separator grease station should be installed in the center of the lubricating system. The distributer should be fixed in the device which needs lubrication, with its installing station convenient for observation and maintenance. Cold rolled seamless steel tube can be generally chosen as to the texture of the lubricating pipeline.
  • Electric lubrication system
The electric lubrication is generally installed in the central part of the electric lubrication system, and usually need to set up special lubricating state with assurance of tidy and clean. The differential pressure switch is generally installed at the end of the main pipe line, behind the switch there should be installed a distributor. The piezometer however is commonly installed near the switch. The requirement for the texture is same as that of the Manual lubrication system.

Introduction of Shuttle Conveyor

Shuttle conveyor is designed for conveying material moves along a transport direction on the steel track which is usually installed on the top of the storehouse.Reversible conveyor mainly used to discharge material constantly in multi-point when the discharging points could move.

► Advantages

    1.Multiple discharge point
    2.Discharge continuously in long distance
    3.Two way running and discharging
    4.Compact structure with low height
    5.Convenient installation and maintenance
► Application
Large capacity shuttle conveyor is mainly used for disperse and store the material, especially the materials need to discharge averagely in order to take full advantage of the space and then store more material. So it could be used in agriculture, power plant, raw material stocking, metallurgy industry, etc.

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.
