Belt conveyor is a frequently used equipment in mining production. It has large transportation capacity and low power consumption. It is an indispensable machine in industrial production. For the overhaul and maintenance of belt conveyor machinery, the belt conveyor accessories should be replaced regularly, inspected on time, and used reasonably, Very important.

If the belt conveyor head vibrates, the reasons are as follows: If it is a suspended mine conveyor belt structure, it is mainly caused by uneven body and a weak base. Correct it, such as vibration of the electric drum and the upper-aligning roller group because of its absence. On the same straight line, or poor coordination with the frame, check the motor for damage even if it is possible. If it is a fixed conveyor, check whether the motor, gearbox, and base are on the same plane. If there is any looseness, fasten it quickly;

In addition, belt deviation is a common abnormality: the deviation of the rubber conveyor belt affects production, damages the tape, increases resistance, and reduces equipment use time. The entire belt is inclined to one side, mainly due to incorrect belt head and tail rollers, or improper belt joints. The user can inspect the condition of the endless conveyor belt joints by adjusting the rollers at both ends and the existing objects on the spot, and adjust the reversing rollers and the correcting roller set. If the rollers at the head of the belt conveyor are off-track, Generally, it will deviate to the right. You can move the bearing seat forward to push the shaft forward. If it is to the left, move the left bearing seat forward. According to industry experience, the belt is running tighter and tighter, and the tail drive roller is adjusted. The method is opposite to that of the head. If the idler is running off-track, move the idler group to the side of the off-track movement toward the direction of the belt body, and at the same time install stop rollers or multiple sets of self-aligning brackets at the off-track position Roller, if the conveyor belt is not deviated, check its tension at this time, and adjust the tensioner to solve it.

Area and slippage of belt belts in mines: The main reasons for belt slippage are roller damage, belt deviation, debris entanglement, driving drum or belt body with mineral mud, heavy loads, increased belt resistance, and slipping caused by exceeding the power of the electric drum. In addition, the conveyor belt is too loose, the non-slip chevron pattern conveyor belt is not used, the roller lagging is worn out, and the friction coefficient of the roller lagging under muddy and wet conditions will quickly decrease, and the driving force will decrease. Replacement of the ceramic rubber sheet will have a significant anti-skid effect.

Belt conveyor noise: Check whether the driving roller, the reversing roller, and the idler group are in non-working state. Usually the bearing is less oily. At this time, just add lubricating oil, in the coupling between the motor and the reducer. The noise of the device is caused by the over-regulation of the matching clearance between the gears, which can be adjusted according to the assembly instructions;

Belt conveyor does not start: first check the electronic control system, including the start-up device, protector, whether the power supply is normal, whether the protection is working, whether the position is correct, etc., check one by one, check the frequency of use of the open-air flame-retardant conveyor belt in the mine every day, Operating time, the cleanliness of the cleaner on the belt conveyor, whether there is sticky material on the return belt, etc.

Finally, visual inspection of the appearance of the rubber conveyor belt for long-distance transmission operations: whether it is cracked and aging, and the structure of the rubber layer is observed by two broken cuts. Because the operation of the mine belt conveyor equipment is a key process, it is necessary to achieve regular maintenance and timely maintenance. Replacing old parts and maintaining on time can fully ensure efficient production and operation services for users.
