Use B6150SE, B7150SE, B9100SE and historical B5100SE models to identify rotor wear parts, tungsten-carbide materials, shafts, drives and dedicated maintenance tools.
This page uses original Metso Barmac model, rotor and wear-part literature. Published data identify installations; part supply still requires the full model, rotor dimensions, serial number, drawing and drawings.
The three current models use current OEM B Series literature. B5100SE comes from the 2011 OEM wear-parts application guide and is retained explicitly as a historical installed model.
| Model / Status | Maximum Feed | Speed | Power | Capacity / Weight |
|---|---|---|---|---|
| B6150SE · Current | 37 mm | 1,500–2,500 rpm | 75–160 kW | 60–217 t/h; approximately 6,400 kg (including motor) |
| B7150SE · Current | 45 mm | 1,100–2,100 rpm | 160–320 kW | 125–545 t/h; approximately 12,400 kg (including motor) |
| B9100SE · Current | 50 mm | 1,000–1,800 rpm | 320–600 kW | 263–775 t/h; approximately 14,400 kg (including motor) |
| B5100SE · Historical Installation | 30 mm | 2,000–3,400 rpm | 37–55 kW | 15–60 t/h; confirm weight from installation records |
The numbers on the diagram correspond one to one with the rows below.

Tips face high-speed discharge impact; distributor plates face feed impact and abrasion. Upper/lower and trail plates maintain the rotor rock bed. Material selection must account for position and failure mode.
Rotor Tip Set
The last high-wear parts contacted before material leaves the rotor. OEM literature lists Hard, Extra Hard and XX Hard tungsten-carbide inserts with different impact/abrasion balances. Replace matched sets at each outlet to maintain balance. Verify parts by full Barmac model, rotor size, serial number, drawing, profile and interfaces.

Back-up Tip
Behind the main tips, these protect the rotor if a tip breaks or wears through. They provide short-term protection and are not intended for continued long-term running. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.

Tip / Cavity Wear Plate
Protect outlet edges and exposed faces from high-speed rebound impact. OEM instructions require matched, evenly distributed sets; reversible designs are turned according to wear. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →
Upper Internal Wear Plate
Protect upper internal surfaces and stabilise the rotor rock bed. The OEM guide does not offer freely interchangeable materials, so confirm material and profile against original drawings, full model, rotor size, serial number and interfaces.
View the General Component Page →
Lower Internal Wear Plate
Protect lower internal surfaces and usually wear faster than upper plates. A complete rotor has three upper and three lower plates, replaced as sets to maintain balance. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →
Distributor Plate
Takes vertical feed impact and distributes material into three rotor passages. Published designs include flat, conical, extra-thick conical, two-piece and tungsten-carbide-topped plates. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →
Trail Plate
Maintain the rock-bed shape behind rotor tips. Large rotors have narrow, wide and extra-wide options, with optional tungsten-carbide edges. Width and angle affect wear across the rotor. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →
Feed Tube
Fixed in the upper feed assembly, it directs all feed into the rotor opening and faces continuous abrasion. Some rotors have different openings for high/low capacities. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →
Feed Eye Ring
Rotates with the rotor at its inlet and guides material together with the fixed feed tube. Profile, locking design and clearances must match the rotor. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →
Top / Bottom External Wear Plate
Protect external upper and lower rotor surfaces. OEM options include designs with or without hardened-steel wear lips. Abnormal top wear often relates to feed tube or eye-ring failure. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →Only spare systems identifiable in the original Barmac design are listed. Verify interfaces, accuracy, configuration and interchangeability against the full machine model, serial number and drawings.
Rotor Assembly / Rotor Body
The B Series main rotating assembly includes the body, rock-bed areas and wear-part mounts. Complete supply requires rotor diameter, deep/shallow design, outlet count and balance checks, plus full Barmac model, serial number, drawing, profile and interfaces.
View the General Component Page →
Vertical Shaft Line Assembly
Located in the base assembly, supporting the rotor and transmitting high-speed loads. Verify journals, tapers, threads, heat treatment, non-destructive testing and balance against original drawings and serial number, plus full model, rotor size, profile and interfaces.
View the General Component Page →Rotor Bearing
Carry the high-speed vertical shaft. Bearing designation, clearance, fits, lubricant quantity, temperature rise and matched arrangement require shaft records, not inference from similar models. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →Bearing Seal / Lubrication Components
Exclude dust and maintain automatic shaft lubrication. Check seal design, elastomers, grease, pipe interfaces and grease supply by full model and shaft configuration. Verify rotor size, serial number, drawing, profile and installation interfaces.
View the General Component Page →Drive Sheave / Pulley
Set rotor speed through the belt drive. Check diameter, groove profile, bore, taper bush, speed and balance together with motor and shaft. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →Matched Drive V-Belt Set
Matched consumables for the high-speed drive. Replace and adjust the whole set for section, effective length, count, capacity and tension. Verify full Barmac model, rotor size, serial number, drawing, profile and interfaces.
View the General Component Page →Current Metso product pages and B Series literature explicitly list top lifting, rotor service arms and maintenance lifting tools. Confirm applicability by machine model and site configuration.
Moves the lid and upper feed assembly to expose the rotor. Check model, lifting load, swing space, mounting foundation and safety locks.
Support rotor removal, transfer and positioning, reducing reliance on external cranes for routine maintenance. Verify lifting points, rotor weight, arm length and working radius by model.
Replace tips, backup tips and cavity plates in evenly matched sets at each outlet. Tools and replacement sequence must maintain rotor balance and personnel safety.
Provide the full model, serial number, rotor diameter and deep/shallow design, part drawing, current-part photographs, feed size, abrasiveness, rotor speed and used-part wear condition.
The B Series name alone is insufficient. Verify rotor size, deep/shallow design, outlets, part profile, drawing, serial number and dynamic-balance configuration.
OEM literature distinguishes impact-oriented, abrasion-oriented and high-wear-resistance/low-impact-resistance carbide grades. Feed size, hardness, abrasiveness, moisture and tramp-metal risk determine the final choice.
