Condition: as good as new (ex-display), functionality: fully functional, overall weight: 700 kg, total length: 900 mm, total width: 2,100 mm, total height: 2,200 mm, input voltage: 400 V, input frequency: 50 Hz, compressed air connection: 5 bar, electrical fuse: 20 A, The Ring Tester is engineered for automated crack detection on ring-shaped components, such as bearing races and gears, utilizing the eddyvisor C. In addition to crack testing, customers can inspect for grinding burn on the inner and outer rings of roller bearings. For this purpose, a robot manipulates and guides the sensor precisely along the contours of the test part. Testing is conducted using up to two probes. All relevant scanning parameters and communication protocols for controlling the eddyvisor C are integrated into the robot scanning program. Dcedpfx Akeyx E D Eecjg At the heart of the system is the eddyvisor C, a two-channel eddy current instrument, ensuring highly reliable detection of cracks and grinding burns. Process automation is achieved by an integrated Stäubli TX2-60 robot. The entire system is managed and operated via a control cabinet equipped with an integrated control and operating panel. A vertical spindle with chuck reliably clamps each test component during the inspection process. Non-conforming (NOK) parts identified during testing are automatically discharged to one of two designated NOK storage conveyors. Separate storage locations for reference and master parts facilitate calibration and ongoing quality assurance during operation. The system also incorporates the ibg Optical Reflection Sensor (iORS), enabling precise, non-contact inspection of rings.

Condition: new, functionality: fully functional, power: 55 kW (74.78 HP), Year of construction: 2026, Ball Mill for Powder and Mining Plant: Structure, Function, and Technical Details A ball mill is a key grinding machine widely used in mining, metallurgy, cement, chemical, and powder-making industries. It is designed to grind various ores and other materials into fine powder through impact and attrition between steel balls and the material inside a rotating cylindrical shell. In mining plants, ball mills are essential for ore beneficiation, preparing materials for flotation, magnetic separation, or leaching processes. In powder production, they ensure uniform particle size and high surface area for further processing. Working Principle The ball mill operates on a simple yet effective principle: as the cylindrical shell rotates around its horizontal axis, the grinding media (steel or ceramic balls) are lifted along the inner wall by centrifugal force and friction. When they reach a certain height, they fall freely, striking and grinding the material below. This repeated motion causes both impact and abrasion, reducing the material to the desired fineness. The grinding process can be performed in dry or wet conditions depending on the application. Structural Composition A standard ball mill consists of several main components: Feeding part: Equipped with a feeder or screw conveyor to ensure uniform material input. Discharging part: Can be grate type or overflow type, depending on the discharge method. Rotating part: The cylindrical shell made of steel plates, lined with wear-resistant liners. Transmission system: Includes motor, reducer, small transmission gear, and electrical control. Grinding media: Steel balls or ceramic balls of different diameters for efficient grinding. The internal liner design and ball size distribution are optimized to achieve maximum grinding efficiency and minimal energy consumption. Technical Details Typical Specifications: Feeding size: ≤25 mm Discharge size: 0.074–0.4 mm Capacity: 0.65–615 t/h (depending on model and material hardness) Cylinder speed: 18–38 r/min Power: 18.5–4500 kW Liner material: High manganese steel, rubber, or alloy steel Grinding media load: 30–45% of cylinder volume Operating Modes: Dry grinding: Suitable for materials that must remain moisture-free, such as cement clinker, limestone, and quartz. Wet grinding: Common in ore beneficiation, where water or slurry improves grinding efficiency and particle uniformity. Dcedpfx Aeq Nf U Eokcjg Application in Mining Plants In mining operations, ball mills are used after crushing to further reduce ore size and liberate valuable minerals. They are integrated into grinding circuits with classifiers, hydrocyclones, and flotation systems. The ground material is classified by size, and oversized particles are returned to the mill for regrinding. This closed-circuit system ensures consistent product fineness and efficient energy use. Common Applications: Gold, copper, iron, and zinc ore grinding Cement clinker and slag processing Silicate and ceramic powder production Coal and mineral powder preparation Conclusion A ball mill is an indispensable piece of equipment in both powder production and mining beneficiation plants. Its ability to grind materials into fine, uniform particles makes it vital for downstream processes such as flotation, sintering, and chemical reactions.
