The installation of belt conveyor is generally carried out in the following stages:

1. Installation of belt conveyor frame is started from the head frame, then the middle frame of each section is installed in turn, and finally the tail frame is installed. Before installing the frame, the center line should be drawn on the whole length of the conveyor, because keeping the center line of the conveyor in a straight line is an important condition for the normal operation of the conveyor belt, so when installing each section of the frame, the center line must be aligned, and the frame should also be leveled. When all the single sections are installed and found correctly, the single sections can be connected together.

2. Install the drive unit. When installing the drive unit, care must be taken to make the drive shaft of the belt conveyor perpendicular to the center line of the belt conveyor, so that the center of the width of the drive roller coincides with the center line of the conveyor, and the axis of the reducer is parallel to the drive axis. At the same time, all shafts and rollers should be leveled. The leveling error of the shaft is allowed to be within the range of 0.5-1.5mm depending on the width of the conveyor. At the same time of installing the drive device, tensioning devices such as tail wheel can be installed. The axis of the roller of the tensioning device should be perpendicular to the center line of the belt conveyor.

3. Install the rollers. After the installation of the frame, drive device and tensioning device, the upper and lower rollers can be installed, so that the conveyor belt has a slowly changing curve, and the pitch of the bending section is 1/2 to 1/3 of the normal pitch of the rollers, and after the installation of the rollers, the rotation should be flexible and light.

4. The final alignment of belt conveyor. In order to ensure that the conveyor belt always runs on the center line of the rollers and rollers, the following requirements must be met when installing the rollers, frame and rollers:

(1) All the rollers must be lined up in rows, parallel to each other, and kept horizontal in the lateral direction.

(2) All rollers must be in rows parallel to each other.

(3) The supporting structure frame must be straight and horizontal in the transverse direction. For this reason, the centerline and level of the conveyor should be finalized after the drive rollers and roller frame are installed.

5. Then fix the frame on the foundation or floor. After the belt conveyor is fixed, the feeding and discharging device can be installed.

6. When hanging the conveyor belt, lay the belt strip on the roller of the no-load section first, and then lay it on the roller of the heavy-load section after hugging the driving roller. A 0.5-1.5t hand winch can be used to hang the belt strip. When tensioning the belt strip for connection, the drum of the tensioning device should be moved to the limit position, and the trolley and spiral tensioning device should be pulled and moved in the direction of the drive; while the vertical pick-up device should make the drum move to the top. Before tensioning the conveyor belt, the reducer and motor should be installed, and the inclined conveyor should be installed with a brake device.

7. After the installation of belt conveyor, it is necessary to carry out idling trial. In the idling trial, we should pay attention to the running of the conveyor belt, the running temperature of the driving part, the activity of the rollers, the tightness of the contact between the cleaning device and the guide plate and the surface of the conveyor belt, etc. At the same time, we should make the necessary adjustments, and only after all parts are normal can we run the trial with load. If the spiral tensioning device is used, the tightness should be adjusted once again when running the machine with load.

Before running the belt conveyor, first of all, we should confirm that the belt conveyor equipment, personnel and conveyed goods are in a safe and intact condition; secondly, we should check that all moving parts are normal and free of foreign objects, and check whether all electrical lines are normal, and only when they are normal can the belt conveyor be put into operation. Finally, check that the difference between the supply voltage and the rated voltage of the equipment is not more than ±5%.
