How to Adjust the Blade Gap of Single Shaft Shredders

Completely shut down the machine and disconnect the power supply before starting any adjustment work to prevent accidental startup and ensure operator safety.

Open the machine’s access panel to expose the blade assembly. Clear all residual materials or debris from around both moving and fixed blades to ensure unobstructed operation.

Identify the adjustment screws or bolts connecting the fixed blade holder to the machine frame. These allow for precise tuning of the distance between the blades.

Using appropriate tools, loosen the locking nuts. Incrementally turn the adjustment screws to move the fixed blade closer to or farther from the rotating blades. Ensure adjustments are made evenly on both sides of the assembly.

Use a feeler gauge to check the gap between the blades, matching it to the required specification for your material. Make minor adjustments as needed.

Once the desired gap is achieved, retighten all locking nuts securely. Close the access panel, reconnect power, and run a material test to verify shredding quality.
