Identify HIGmill installations and assess materials and drawing-based supply for GrindForce grinding rotors, stator rings, shell liners, main shafts and drive spares.
HIGmill is a vertical stirred mill for fine grinding, ultrafine grinding and regrinding. Its design comprises a mill body, main shaft with grinding rotors, shell-mounted stator rings, gearbox and drive. Feed enters at the bottom and passes upwards through successive grinding stages.
The range specifications describe overall equipment capabilities. The named models below relate to published installations or pilot trials. Confirm spare parts against the nameplate, serial number, drawing, general arrangement and drawing revision.
| Series / Model | Published Power / Configuration | Size / Identification Requirements |
|---|---|---|
| HIGmill Industrial Range | Unit power up to 6,500 kW | Chamber volume up to 50,000 L; confirm model and dimensions from project records, nameplate or drawings |
| HIG3500/23000 | 3,500 kW; published installation | 23,000 L; Sunrise Dam Item |
| HIG500/4000 | 500 kW; published installation | 4,000 L; Cracow project, with a footprint of approximately 2.7 m × 2.3 m |
| HIG25 | Pilot Equipment | Cracow site pilot trials; specify power and dimensions from the equipment records |
| HIG5 | Test Equipment | Sunrise Dam scale-up testwork; specify power and dimensions from the equipment records |

Identify wear parts by grinding stage and installation position. Match candidate materials and processes to abrasion, media wear and slurry corrosion, confirming the material, design and drawing for the installation.
GrindForce Grinding Rotor
Mounted along the main shaft, grinding rotors face continuous abrasion and shear from ceramic media and slurry. Lower stages can experience greater pressure and wear. Published projects include steel and rubber-covered castellated rotors. Select materials for particle size, media density, speed and drawing requirements.
Explore Grinding Rotors →Shell-mounted Stator Ring
Stator rings attach inside the mill body and work with rotating rotors to form successive grinding stages and control media movement. Check stage position, internal and external diameters, thickness, segmentation, fixings and rotor clearance. Published projects include rubber-covered stationary elements.
Explore Stator Rings →
Mill Shell Liner Components
Shell liners protect the body against media and slurry wear. Conditions vary with height; check remaining thickness, segmentation, curvature and fixings in lower feed and high-pressure zones. Published cases include fully vulcanized rubber-covered stationary elements and shell linings.
Explore Shell Liners →Identify drive and structural spares separately. For gearboxes, main shafts, bearings, seals and split mill bodies, confirm interfaces, tolerances, materials, heat treatment and installation drawing before manufacture.
Main Shaft and Rotor Support Assembly
The main shaft transmits top-drive torque and supports the grinding rotors. Check overall length, shaft diameters, rotor interfaces, keys or connections, runout, heat treatment and dynamic balance. Specify the shaft alone or the complete assembly separately.
Explore Main Shafts →
Gearbox and Drive Components
The top drive powers the vertical main shaft. Identify gears, pinion shafts, couplings, bushes and connectors from installation drawings, checking tooth profile, module, accuracy class, material, heat treatment and fits.
Explore Drive Parts →Split Mill Body and Structural Components
HIGmill uses a flanged split mill body for maintenance access. Check diameter, section positions, flange hole patterns, concentricity, welding and nondestructive testing requirements, and stator and liner interfaces.
Explore Mill Body Parts →
Bearings, Sleeves and Shaft Seals
For main shaft support, location and slurry isolation. Check bearing designations, housings, bush dimensions, lubrication, seal design, elastomer compatibility and operating temperature against installation drawings.
Explore Bearings and Seals →Provide the complete model, serial number, drawing revision, installation position, photographs of the current part, material and operating conditions.
No. Photographs help identify equipment and part types. Manufacturing requires confirmed drawings, dimensions, interfaces, materials, heat treatment and acceptance criteria.
Start with the nameplate, general arrangement drawing, installation position, photographs of the existing part and critical dimensions. These support assessment of measurement, material selection and drawing-based manufacturing requirements.
Provide the full model, serial number, nameplate, part position, photographs of the existing part, drawings, material and operating conditions. These support identification, material assessment, manufacturing coordination, quality control and finished-part delivery.

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.
