Fitting the screen in the Vieira MCO hammer mill
Updated on By Moinhos Vieira – technical team
In short
In the Vieira MCO mill the screen sits loose inside its frame: fit the screen into the frame and place the assembly in the grinding box, with the frame guide pin in the guide hole at the bottom of the box.
Step by step
Switch the mill off and wait for it to stop
Never change the screen right after switching off: wait for the rotor to stop completely. Wear protective gloves to handle the screen.
Place the screen in the frame
The screen is supplied separately from the frame. Fit it carefully inside the frame. It works loose: it does not need to be fastened.
Open the grinding box door
Open the door to reach the bottom of the grinding box.
Fit the assembly with the guide pin
Place the assembly (screen and frame) inside the grinding box, fitting the frame guide pin into the guide hole at the bottom of the box.
Close the door and check
Close the grinding box door properly and check the fit before starting the mill.
If you are unsure about any step, stop and contact technical assistance.
When to check the screen
- The product particle size has changed: the screen may be damaged or poorly seated in the frame or in the guide hole.
- Metallic clicking inside the mill: besides a foreign object, it may be the fit of the screen in the frame.
- Output has dropped: the screen may be worn or clogged.
See what to do in each case in troubleshooting. The screen hole size affects the result: a finer screen tends to give a finer product. To choose the right screen for your product, talk to our team.
When ordering a new screen or frame, give the model shown on the mill identification plate.
