Use VTM models and key dimensions to identify screw wear liners, end liners, wear caps, shaft liners, Orebed® magnetic liners, drive spares and maintenance tools. Drawing references, generations and dimensions guide manufacture in China, quality control and delivery.
Vertimill® is Metso's gravity-induced vertical stirred mill range. Screw liner quantities, hole patterns, lifting points, rubber pads and model details differ across VTM, W/WB, C/LS and legacy VGX models. Only model and component relationships supported by manufacturer information are published here.
Only overall dimensions, installed power and empty weight needed for spare-part identification are listed. Model numbers denote horsepower classes and must not be read directly as kW. Confirm each project against the nameplate, data sheet and general arrangement.

Numbers follow the Metso Vertimill® wear parts catalogue, retaining legacy W/WB, C/LS and VGX installation relationships. ANRANST is an independent wear-parts engineering team; manufacturer authorization is not implied. Enquiries require model, serial number, liner generation, drawings and used parts to be checked together.

Loads and wear differ by position. Screw liners withstand abrasion and stirring loads; shaft components isolate erosive flow; Orebed® uses magnetic material to form a protective layer. Determine materials by position, drawing and operating conditions.
Screw Wear Liners
Mounted on the working face of the screw flights to protect the screw body and maintain its profile. Check model, generation, quantity per mill, holes, thickness, lifting points and wear direction. The cast wear-resistant alloy must be checked against the drawing.
End Liners
Located at the lower end of the screw, usually as two pieces per mill. This area encounters slurry erosion, abrasion and local impact. Check inner and outer profiles, paired fit, generation and lifting holes.
Wear Cap Kits
Protect the bottom of the screw shaft. Cast iron, rubber or rubber/polyurethane designs vary by model and generation. Appearance alone is insufficient; check the original model details, fastening holes and shaft-end interface.
Shaft Liners & Adapter Plates
Shaft liners protect the screw shaft from slurry and abrasive particles; adapter plates and wedges form the mounting interface. The manufacturer catalogue specifies rubber shaft liners and mild-steel adapter plates. Check section quantities, weld positions and clamping relationships.
Attachment Hardware & Rubber Pads
Includes oval-head bolts, special washers, nuts and rubber pads used with specific polyurea-lined shaft configurations. Check threads, lengths, quantities per liner, preloading method and liner generation.
Orebed® Magnetic Liners
Used on the mill wall and door, with permanent ceramic magnets embedded in wear-resistant rubber. A protective layer forms only when the media or slurry contains enough ferromagnetic material. Designs differ between VTM-1500 and smaller models and VTM-2250 and larger models.
Shaft protection parts vary by model and generation. Rubber, rubber/polyurethane and cast-iron versions must not be mixed. The following are identification numbers from the manufacturer catalogue.

All-rubber units are used for VTM-1500 and smaller models; steel-capped units for VTM-2250 and larger models; high-temperature steel-capped units for lime slaking. Applicability still depends on material magnetism and the original construction.

The fixed-speed motor, planetary gearbox, spherical roller bearings and suspended screw form the Vertimill drive and support system. Check spare parts together against the specific model, shaft arrangement, interfaces, lubrication and mounting datums.
Motor & Planetary Gearbox Interfaces
Check VTM model, power, output shaft, flanges, connectors, rotation direction, lubrication connections and installation elevation. Identify internal gearbox parts from the nameplate, assembly number and manufacturer drawings; general tower-mill data is not a substitute.
Open General Drive Identification →Spherical Roller Bearings & Supports
Support the suspended screw shaft. Check the complete bearing designation and suffix, clearance, fits, housing, seals, lubrication and fixed/floating-end arrangement. Do not infer specifications from appearance.
Open General Bearing and Support Identification →Screw Shaft & Screw Body
These are large structural spares, distinct from screw liners. Check overall length, journals, flanges, screw geometry, liner holes, welding and nondestructive testing. Identify shaft protection liners separately from the shaft itself.
Open the General Shaft Structure Page →This table applies only to the archived VTM-3000-WB wet vertical stirred mill project revision. Project assembly and general drawing differ in identification level from individual wear liner and end liner numbers in the public catalogue. Recheck the complete nameplate, serial number, drawing revision and actual interfaces; do not extrapolate to other VTM-3000-WB installations.

Identification boundary: 05-066938 is this project's screw wear liner assembly number. It is not an individual wear liner number listed by generation in the public catalogue. Cross-check both with drawings, quantities, interfaces and installation revision.
Only special tools explicitly listed in Metso Vertimill documentation are shown, with applicable models and component numbers. Select tooling by liner generation, working load and the specific maintenance task.
Install new liners and remove worn liners while maintaining the designed center of gravity and lifting angle. Tool numbers differ by VTM model, wear or end liner, and generation.
Includes service platforms, beam assemblies, support bases, lifting lugs, transport trolleys and screw jacking components. It supports, rotates and transports the screw shaft and liner assembly in front of the mill or in the maintenance area.
Provide the complete VTM model, serial number, wear liner or end liner position, current model details, liner generation, drawings, used-part photographs and key dimensions.
The model alone is insufficient. Manufacturer information lists multiple liner generations, lifting points and mounting parts for one model. Recheck drawing, interfaces, generation and dimensions.
No. It relies on magnetic media or ferromagnetic material in the slurry to form a protective layer. Check material magnetism, temperature, mill model and original construction.
Provide the complete model, serial number, wear liner or end liner position, current model details, liner generation, drawings, used-part photographs, material and operating conditions. We use these to identify the part, organize production at certified foundries, coordinate quality control and deliver the finished item.
