Variable headstock

BRASFELT Variable Head: ideal for dynamic process adaptations.

Introducing the BRASFELT Variable Head, an innovation developed by BRASFELT to revolutionize the filtration process in Vacuum Disc Filters. With a design focused on efficiency and adaptability, this system allows the pie forming area to be adjusted dynamically without the need to stop operation. This flexibility is achieved thanks to a movable plate, regulated by gears, and an external adjustment shaft to the Variable Head.

The BRASFELT Variable Head (Patent BRASFELT PI0705919-1) has the following advantages:

Rapid response to process demands: The variable angle of the forming zone allows a better adaptation of the filter to the process demand and/or to the characteristics of the pulp in terms of density, solid concentration and increase or decrease in cake thickness, as described below:

• Maximum training area: the opening of the training area is as large as possible, increasing the training time.
• Minimum training area: the opening of the training area is as small as possible, reducing the time of training. 
• An association of these two situations with a suitable rotation of the filter, which will be defined according to the process characteristics of the moment, will allow an optimization between the highest possible production for the expected humidity.

Reduced downtime and simplified, ergonomic adjustment: Allows the opening of the pie-forming area to be changed at any time while the filter is still in operation, meaning that the filter does not need to be stopped to change the opening of the forming zone, keeping the opening of the drying zone fixed;

This innovation reaffirms BRASFELT’s commitment to excellence, always focused on custom development, using specialized engineering, reinforcing its position as a solid-liquid separation solutions company.
