Crane Configuration for Mining Equipment Manufacturing
Kelude cranes for mining equipment manufacturing are configured across four categories: crushing, grinding, flotation, and thickening. QD Type 30–100t for jaw plate hoisting in crushers, QD Type 50–150t for ball mill shell turnover, LD Type 10–30t for flotation cell bodies, and LD Type 10–30t for thickener rakes. Complete plant solutions range from 150,000 to 1,500,000 USD.
Crusher Manufacturing: Heavy Lifting for Jaws and Cones
Jaw crusher frames weigh 10–40t, with moving jaws at 5–20t. Cone crusher main frames range from 10–30t. The recommended configuration is QD Type 30–100t. Kelude standard equipment includes dual braking and anti-sway control.
The toggle plate in a jaw crusher is the critical component for adjusting the discharge opening. Assembly precision of the toggle seat directly affects the discharge setting, with an adjustment range of ±5mm. Kelude crusher cranes are designed for precision alignment with the toggle seat.
Grinding Equipment: Ball Mill Shell Turnover Solutions
Ball mill and SAG mill shells range from 3–6m in diameter and 5–12m in length, weighing 20–80t. The recommended configuration is QD Type 50–150t. Shell turnover requires a dedicated spreader beam working in tandem with a turnover jig.
Liner plates (manganese steel or rubber) inside ball mill shells typically need replacement every 3–6 months. Each mill contains 100–400 liner plates, with individual weights from 50–200kg. Liners must be hoisted into the shell one at a time. Kelude cranes for the grinding section are paired with liner-changing manipulators for efficient installation.
Flotation Machine Manufacturing: Large Cell Body Installation
Flotation cell capacities range from 10–200m³, with cell bodies weighing 3–15t. The recommended configuration is LD Type 10–30t. Multi-cell flotation assembly lines require long-span coverage to accommodate side-by-side cell layouts.
The gap between the impeller and stator in a flotation cell (2–5mm) directly affects bubble generation quality. Impellers weigh 200–800kg and are made of wear-resistant rubber or polyurethane. Kelude cranes for the flotation section enable precision alignment of impellers and stators.
Thickener Manufacturing: Precision Assembly of Rake Structures
Thickener rake structures range from 10–40m in diameter and weigh 5–20t. The recommended configuration is LD Type 10–30t. Coaxiality between the rake and drive unit must be maintained within 0.5mm.
Welding distortion must be controlled during rake fabrication, with overall straightness held to ≤5mm across the full length. Coaxiality between the rake drive shaft and gearbox must not exceed 0.5mm. Kelude cranes for the thickener section support rake turnover and assembly welding.

FAQ: Ball Mill Liner & Maintenance Solutions
Q: How do you handle ball mill shell turnover?
A: A spreader beam with multi-point lifting combined with a turnover jig ensures smooth, stable shell rotation. Kelude supplies dedicated spreader beams for shell turnover (50–150t capacity, adjustable suspension point spacing from 2–4m).
Q: How often should crusher jaw plates be replaced?
A: Depending on ore hardness, jaw plates typically need replacement every 3–6 months. Kelude's C-Hook enables rapid changeouts—a single jaw plate (200–2000kg) can be swapped in 30 minutes or less.
Q: What span is required for a flotation machine assembly line?
A: For side-by-side flotation cell layouts, a recommended span of 22–31.5m allows a single crane to cover the entire flotation line. Kelude also offers non-standard spans up to 34.5m.
Q: What is the recommended approach for ball mill liner replacement?
A: Ball mill liner plates typically weigh 50–200kg each, with 100–400 plates per mill and a replacement interval of 3–6 months. We recommend pairing a liner handling manipulator with an overhead crane. Kelude supplies complete liner lifting spreader systems for this application.
