Replacing impact strips on a rotor breaker in 5 steps
Replacing the stroke strips of a rotor breaker or turning them is described in five steps here in this post.
The rotor is equipped with 4 impact strips which systematically wear down as the machine works through friction and contact with the feed material.
The impact strips are rotated or replaced in pairs each time and periodically depending on abrasiveness, compressive strength and CSS of the rotor crusher.
The operator of the machine shall be alert at all times and check the condition of the impact strips regularly while operating the mobile crusher.
This not only to ensure the proper production of the machine. Especially to prevent the rotor itself from deteriorating and being damaged in case of excessive wear of the stroke strips.
Proper follow-up and monitoring can prevent major damage and repair costs.
- Step 1: Securing the rotor using the safety pin.
This locks the rotor and prevents it from starting to turn unwanted during operations due to imbalance.
- Step 2: Remove locking plate which centers the striker bar with two socket head bolts.
- Step 3: Using a hydraulic cylinder, press the striker bar laterally out of the rotor in three steps, suspend it in the suspension yoke.
- Step 4: Now manually rotate the striker bar in the yoke and slide it back into the rotor.
- Step 5: Reinstall the locking plate and remove the safety pin.
Now repeat these work steps for the opposite stroke bar in the rotor. After this work, the CSS should be reset to the correct opening. This is done by topping up with additional thickness plates which hold the counter frames at the correct position of the stroke bar and this according to the desired end product to be produced.
