Belt conveyor rebuild, which parts can be utilized?

According to the structure of the belt conveyor equipment, take the commonly used trough belt conveyor as an example, the main composition by the frame, conveyor belt, roller, rollers, hopper-based.
Drive unit part can be utilized: motor (if the power is sufficient); reducer (need to calibrate the torque); coupling (if the size match)

Control system: control cabinet (may need to expand capacity); sensors (such as deflection switch, pull rope switch, etc.)

Other components: roller (if the shaft diameter and bearings meet the new load requirements); sweeper (may need to adjust or replace the scraper)

Rack roller frame part due to the overall widening, the roller frame part can not be depreciated, the rack part is not recommended to be depreciated (the cost is too high).
And need to replace the parts may be more, after all, the bandwidth affects the composition of the entire equipment structure:

1. Conveyor belt (must be replaced with 800mm width)

2. Roller set (has to be replaced to suit the 800mm bandwidth)

3. Reversing rollers (must be replaced with wider sizes)

4. Tensioning device (may need to be adjusted or replaced)
Special attention is required when retrofitting:

1. Comprehensive force analysis and power calibration must be carried out

2. Check the load carrying capacity of the existing structure for the new bandwidth

3. Evaluate whether the drive system meets the power requirements of the new bandwidth

4. Consider the effect of changes in conveyor length on the tensioning system.

5. Adjustment of conveyor inclination may be required (if applicable)
