Crusher rotor balancing.
Very complicated of rotor balancing . Very old Crusher was completely not suitable for use. Bad was absolutely everything! Nondestructive testing showed that both bearings should be replaced. The frame on which the rotor is installed needs to be repaired. The knives were worn out and could not be fixed on the rotor. To balance this crushers took more than 50 kg weights.
Despite all the difficulties we repaired it!
