Replacing impact strips on a rotor breaker in 5 steps

Replacing or rotating the stroke strips of a rotor breaker 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. This is done periodically depending on the abrasiveness, compressive strength and CSS of the rotor crusher. The operator of the machine will be alert at all times and regularly check the condition of the impact strips while operating the mobile crusher. This is not only to ensure proper production of the machine, but more importantly to prevent excessive wear of the impact strips from affecting and damaging the rotor itself.
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: Disassemble the locking plate which centers the striker strip with two socket head bolts.

Step 3: Using a hydraulic cylinder, push the striker bar sideways out of the rotor in three steps and hang it in the suspension yoke.

Step 4: Now manually rotate the striker bar into 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 must be reset to the correct opening. This is done by refilling extra thick plates, which hold the counter frames at the correct position of the stroke bar, depending on the desired end product to be produced.
