How to connect the blasting busbar
Busbar is assembled in a way to overlap small alignment parts. The correct connection method for mining blasting lines is crucial for ensuring the safety of mining operations. Typically. There are many situations where it is necessary to join two busbars to create a single, unified unit. This process, called “jointing,” may be needed to create a longer busbar from shorter, more manageable pieces; or to create a T-shaped tap-off connection from the main busbar. From there you're going to have. Mix the mixture with a beater at low speed for at least 30sec - 1 minutes until it is homogeneous. Unscrew the bolts and remove the busbar protection cover.
