Used Ermak Ironworker for sale (77)

Condition: new, Year of construction: 2026, Professional, very powerful and efficient band saw for metal with 45° swivel arm. The perfect solution for ironwork, production and craft workshops. Unparalleled for many years, the design and solid construction make it a perfect solution. Machine description Professional, very powerful and efficient metal band saw with 45° swivel arm, CORMAK BS 712 SW is based on refined solutions making it unrivaled in its class. Arm made of shaped spheroidal cast iron ensures rigidity during operation and absorbs all vibrations. Control panel is located on the arm of the cutter. It features high efficiency and simple handling. Provides cutting in vertical plane and in the plane perpendicular to the axis of the cut material, or at any angle in 45° – 90° range. Element cut can be fed manually or by any feeding device. The feed during cutting is gravitational on the principle of oil flow in a two-chamber hydraulic cylinder. Suitable speed of arm lowering is obtained thanks to the valve controlling oil flow between hydraulic cylinder chambers. Rugged, stable and refined construction as well as the arm made of uniform cast iron provide high rigidity and stability while cutting, ensuring accuracy and long-term reliability. The design of the 20 mm saw blade used in the machine makes it possible to cut large quantities of elements. Required band linear velocity is obtained by changing the ratio on the belt pulley between the worm gear and the driving motor.

Condition: new, Year of construction: 2026, power: 300 kW (407.89 HP), Ball Mill for Mining & Fine Powder Making: A ball mill is a fundamental grinding device widely used in mining, metallurgy, cement, and chemical industries. It is designed to grind 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, while in powder-making industries, they ensure uniform particle size and high surface area for further processing. Working Principle The ball mill operates on the principle of impact and friction. As the cylindrical shell rotates around its horizontal axis, the grinding media—usually 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 breaks down the material into fine particles. The process can be carried out in dry or wet conditions depending on the application. Structural Composition A standard ball mill consists of several main components: Feeding part: Ensures uniform material input through a feeder or screw conveyor. 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 or ceramic balls of various 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 Ijdpfxeq Ngafs An Hjif Grinding media load: 30–45% of cylinder volume Operating Modes: Dry grinding: Used 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. Application in Mining and Powder Production 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. In fine powder production, ball mills are used to produce materials such as silicate, ceramic powder, refractory materials, and chemical raw materials. The uniform particle size achieved by ball milling enhances product quality and performance in downstream applications. Conclusion A ball mill is an indispensable piece of equipment for both mining and fine powder making. Its ability to grind materials into fine, uniform particles makes it vital for ore beneficiation and industrial powder production. With flexible configurations, high efficiency, and reliable operation, modern ball mills provide a cost-effective and energy-efficient solution for large-scale grinding, ensuring consistent quality and productivity across diverse applications.
