FLS VXPmill: طواحين التحريك القرصية المعيارية وقطع غيارها الأساسية

Modular Agitator Discs

Modular Impeller Disc

Discs are stacked along the vertical shaft to agitate the ceramic grinding media and form the VXPmill's main working elements. Confirm the full model, disc outside diameter and thickness, hole pattern, hub interface, installation height, disc count, spacing and rotation direction.

Material and manufacturing checks: FLS describes the discs as solid polyurethane. Confirm formulation, hardness, hub design and molding process against the original part, drawing number and operating conditions.

Agitator Disc Spacers

Impeller Disc Spacer

Spacers set disc axial positions and energy distribution within the chamber. Check inside and outside diameters, length, end faces, registers, keyed or splined and fastening interfaces, disc assembly order and axial clamping method.

Material and manufacturing checks: Published information confirms removable modules but does not specify spacer materials for every installation. Confirm material, surface requirements and fits from drawings or the actual part.

Polyurethane Grinding-Chamber Liners

Grinding Chamber Polyurethane Lining

Protects the vertical chamber and slurry-contact surfaces from continuous abrasion by fine slurry and ceramic media. Confirm shell inside diameter, lining thickness and zones, connections, flanges, inlet and outlet openings, and on-site repair limits.

Material and manufacturing checks: FLS states that VXPmill slurry-contact parts are polyurethane-lined. Confirm formulation, hardness, bonding or mechanical attachment and repair process for the installed mill.

Upper Media Retention Screen

Media Retention Screen

Located in the upper overflow zone, the screen releases ground slurry while retaining ceramic media. Check aperture size, open area, outside diameter, height, segmented design, attachment and clearance above the top disc.

Material and manufacturing checks: FLS's current product page specifies a polyurethane media retention screen. Confirm apertures, supports and material condition against target product size, media size and drawings.

Bottom Feed and Media-Discharge Liners

Bottom Feed and Media-Drain Linings

Bottom feed and media-discharge passages connect to the chamber. During maintenance, ceramic media drain through the bottom valve into a temporary storage tank. Check passage profile, flanges, valve seat, lining, closure element and chamber interface.

Material and manufacturing checks: Confirm polyurethane, engineering elastomers and matching valve-seat materials for liners contacting slurry or media. Do not substitute a conventional tower-mill feed-liner drawing number.

Disc Service Table and Lifting Tools

Disc Maintenance Table and Lifting Tool

FLS's maintenance video shows disc removal, positioning and lifting on a dedicated service table. Design tooling for disc diameter, weight, lifting points, working height, rails or table surface, locking arrangements and available site space.

Media Discharge and Temporary Storage System

Media Drain and Temporary Holding System

Before maintenance, flush the mill and open the bottom valve to drain ceramic media into a temporary tank, clearing space for disc servicing. Confirm tank volume, valves, screening, pumping, piping and the media return route.
