Identify MULTIROK 7 and MULTIROK 9 DUO specifications, rotor configurations, chamber wear parts and drive spares using thyssenkrupp technical data for legacy installations.
MULTIROK 7 and MULTIROK 9 DUO can use open or closed rotors with an anvil ring or an autogenous material bed. Part selection requires the full model, serial number, rotor and chamber configuration. The operating data below support machine identification and are not part manufacturing dimensions.
These values identify the machine and narrow the parts search. Actual operating values depend on the duty and material properties; they must not be used as part manufacturing dimensions.
| Model | Capacity: Open / Closed Rotor | Maximum Feed Size and Rotor Diameter | Drive and Machine Identification |
|---|---|---|---|
| MULTIROK 7 | 120–200 / 100–160 t/h | Maximum feed 75 / 38 mm; rotor diameter 812 / 685 mm | V-belt drive, 160 kW; 20 anvils with an anvil ring; total weight excluding motor: up to 5.7 t with anvil ring, up to 4.9 t with material bed |
| MULTIROK 9 DUO | 250–400 / 180–300 t/h | Maximum feed 125 / 63 mm; rotor diameter 965 / 889 mm | V-belt drive, 2 × 200 kW; 18 anvils with an anvil ring; total weight excluding motor: up to 11.0 t with anvil ring, up to 10.0 t with material bed |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Open rotor | Central rotor in the upper operating-mode view | MULTIROK 9 DUO: upper image open rotor, lower image closed rotor |
| 2 | Anvil ring | Impact ring around the open rotor | MULTIROK 9 DUO: upper image open rotor, lower image closed rotor |
| 3 | Closed rotor | Central rotor in the lower operating-mode view | MULTIROK 9 DUO: upper image open rotor, lower image closed rotor |
| 4 | Material bed | Rock bed around the closed rotor | MULTIROK 9 DUO: upper image open rotor, lower image closed rotor |
The equipment design includes replaceable carbide rotor tips, an anvil ring or material bed, chamber wear plates, heavy-duty spherical roller bearings and a V-belt drive. Part numbers, materials and dimensions must match the installed machine drawings.
Rotor & Carbide Tips
Check rotor type, diameter, rotation direction, carbide tip positions, retention design and old part markings. Specify model details and material grades from the installed machine drawings.
View Rotor Tip Details →Anvil Ring, Anvils & Material Bed
The chamber can use an anvil ring or an autogenous material bed. Check anvil count, ring segments, chamber dimensions, mounting and wear profile; wear parts for these configurations are not interchangeable.
View Anvil Ring Assembly Details →Crushing Chamber Wear Plates
Identify upper, lower and outer wear plate positions, left and right orientation, hole patterns, thickness and adjacent interfaces. Specify material properties from the drawing, feed abrasiveness and failure history.
View Wear Plate Details →Bearing Pedestal & V-Belt Drive
The bearing pedestal uses heavy-duty spherical roller bearings with a V-belt drive. Confirm bearing designation, clearance, lubrication, pulley groove profile, diameter, bore and matched belt set against the installed machine.
View Bearing Pedestal Details →Provide the complete nameplate, serial number and machine records, then identify the rotor and crushing chamber configuration of the MULTIROK 7 or MULTIROK 9 DUO.
No. Identify the open or closed rotor, anvil ring or material bed, serial number, rotor and chamber drawings, old part markings and actual dimensions.
MULTIROK appears in thyssenkrupp Industrial Solutions historical product literature. The former TK Mining business joined FLS in 2022; identify parts using the original nameplate and subsequent business history.
Please provide the full model, serial number, open or closed rotor, anvil ring or material bed configuration, drawing, old part photographs, key dimensions, feed material and failure details.

ANRANST provides customers worldwide with engineering assessment, production at certified foundries to the customer technical requirements, quality control and finished-part delivery for custom wear parts and industrial spares, with scope to support other custom industrial parts.
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Material grades and heat-treatment processes are specified order by order, stated in the technical agreement and tracked through production.
Drawing confirmation, material and process control, production tracking, inspection and acceptance coordination.
We coordinate manufacturing, quality confirmation, packaging and delivery of complete finished parts in a workable, closed-loop supply process.
Provide the existing model, drawings, drawing, materials or operating conditions so we can identify the appropriate technical review and supply route.
