I. Cutting and Forming
CNC Flame/Plasma Cutting Machines: For cutting thick steel plates (e.g., rotary kiln shells).
Plate Rolling Machines (3-Roll/4-Roll): For rolling shells of ball mills and rotary kilns.
Shearing & Bending Machines: For processing medium and thin plate components (e.g., dryer casings).
Presses & Punching Machines: For stamping flanges, gear blanks, and other components.
Large Vertical Lathes: For machining disc-type parts like ball mill end caps and rotary kiln tires.
Horizontal/CNC Lathes: For precision machining of shaft components (e.g., main shafts, drive shafts).
Gantry Milling Machines / Machining Centers: For milling large housings such as crusher frames and rotary kiln support roller bases.
Floor-type Boring & Milling Machines: For processing large and deep holes (e.g., crusher bearing seats).
Gear Hobbing/Shaping Machines: For manufacturing large-module gears for transmission systems.
Grinding Machines (Cylindrical/Surface/Centerless): For precision grinding of shafts and guideway surfaces.
Automatic Submerged Arc / Gas Shielded Welding (CO₂/MIG): For welding rotary kiln shells and ball mill bodies.
Welding Robots: For automated welding of complex joints.
Annealing/Tempering Furnaces: For stress relief of welded parts and quenching/tempering of gears and shafts.
Induction Heating Equipment: For the thermal assembly of large-scale bearings.
Heavy-duty Assembly Platforms / Turnover Jigs: Supporting final assembly of large equipment (lifting capacity $ge$ 50 tons).
Large Gear Meshing Detectors: To inspect the meshing clearance of transmission gears.
Equipment Configuration: Our comprehensive facility covers the entire production cycle, including cutting (CNC flame/plasma, plate rolling), machining (large vertical/horizontal lathes, gantry milling), welding (automated submerged arc, robotic welding), heat treatment (annealing/tempering furnaces), and assembly (heavy-duty platforms, laser alignment). We support high-precision processing for large-scale equipment such as ball mills and rotary kilns.
Technical Parameters: * Lathe/milling positioning accuracy: ≤0.05mm
Gear meshing clearance: 0.1-0.3mm
Welding NDT pass rate: ≥99%
Shaft hardness after quenching/tempering: HRC 35-40
