3.6

Vibration motor (optional)

The vibration motor causes the hopper to vibrate and facilitates steady powder flow towards 
the hopper base.

If the vibration motor is activated, it runs at specified switching cycles.

3.7

Screen (optional)

Various screens for installation in the hopper are available. Screens improve the powder flow 
in the hopper and prevent the powder from clumping. 

Depending on the application, screens also make it easier to fill the hopper.

Hopper with grille

3.8

Protective grille (optional)

Powder mixers with an automatic valve V1 are equipped with a protective grille. It prevents 
access to the valve whose settings cannot be changed by the operator. The protective grille 
is permanently mounted in the hopper above the valve.
