Individual Part Guide
Modular impeller disc function, dimensions, materials and applicable models
Core working parts of vertical disc stirred mills, arranged in stages along the vertical shaft to activate ceramic grinding media. Identify the installation by disc outside diameter, thickness, hole pattern, hub interface, position number and material.
Installation and Function
Part of the disc system in a vertical disc stirred mill
Rotating discs fluidize the media bed to grind slurry particles by attrition during fine and ultrafine grinding. Disc count and axial spacing affect energy distribution in the chamber, so an individual part quotation must match the complete disc arrangement.
Key dimensions and identification details
Parameters to confirm before quotation and manufacture
- Disc outside diameter, overall thickness and working profile
- Centre bore, hub, key/spline or fastening interface
- Disc position numbers, quantities and spacing between adjoining discs
- Rotation direction, speed, dynamic balance and permissible runout
- Grinding media size, density, charge quantity and slurry conditions
Materials and Manufacturing
Solid polyurethane discs
FLS VXPmill literature identifies the rotating discs as solid polyurethane. For the specific formulation, check hardness, abrasion and hydrolysis resistance, tearing, heat buildup under dynamic loading, hub bonding, dimensional stability and operating temperature.
Typical failure checks
Use wear locations to identify material, structural and assembly problems
- Sustained abrasion at disc edges and working surfaces
- Loose or cracked hubs or centre interfaces
- Polyurethane tearing, delamination or damage from dynamic heat buildup
- Disc thickness changes affecting spacing and energy distribution
OEM and model identification
Model references identify installations; they do not establish common dimensions
| OEM / Series | Application and identification notes |
|---|---|
| Current FLS VXPmill product family | Removable discs and spacers; confirm against the disc layout drawing, model and serial number |
| FLS VXP2500 | Documented installed model; confirm disc dimensions and quantities against project drawings |
| FLS VXP10000 | Published project model; disc dimensions cannot be inferred from model numbers alone |
OEM Drawing References, Third-party Part Numbers and RFQs
Check part references together with position, dimensions, material and drawing revision
Provide the full model, serial number, OEM or third-party reference, disc position, disc layout drawing, outside diameter, thickness, hole pattern, hub interface, used-part photographs, current material, grinding media, speed and wear records.
Provide OEM Drawing References Check the installed model, BOM, position and drawing revision Send a Third-Party Part Number Match to the machine, part name, dimensions and material Provide Used Parts, Photographs or Drawings Begin dimensional assessment, material review and manufacturing confirmation
