CB Circular Vibrator

Versatile and powerful

The circular vibrators of the CB range - the latest development from Trowal - are designed to achieve top results regarding surface finish and productivity. The spiral bottom process channel of more than 180° allows for gentle processing combined with a high metal removal rate.

Gate clearing system

This feature ensures that no parts or media can be lodged between separation flap and the bottom of the process channel. The flap is only lowered when the gate area is completely free of parts and media!
