From primary rock reduction to final ore enrichment, Polygonmachine’s plants are engineered for maximum productivity and reliability. Their lineup spans robust crushing, screening, sorting, conveying, washing, drying, stacking, and enrichment equipment – all tailored for heavy-duty mining operations. With a proven track record across Europe and the Americas, Polygonmachine’s machines combine high throughput, energy efficiency, and rugged durability. Engineers and mine operators worldwide trust Polygonmachine for equipment that delivers consistent performance and low life-cycle cost. Polygonmachine’s crushing equipment provides the essential first stage of mineral processing. Heavy-duty jaw crushers form the cornerstone of primary crushing, handling large rocks and ores and reducing them to manageable sizes. Polygonmachine jaw crushers are built for high capacity (up to 350–500 t/h) and feature reinforced frames and wear-resistant jaws. In secondary stages, impact crushers take over: they apply powerful impacts to break materials into smaller pieces. Polygonmachine impact crushers (secondary and tertiary units) use advanced Herbie wear technology to extend liner life and require minimal maintenance. These crushers also emphasize energy efficiency to lower operating costs. For finest shaping of aggregate, Polygonmachine’s high-speed tertiary impact crushers use rotors and adjustable curtains to produce uniform particles from hard materials like limestone and granite. Each crusher is optimized to maximize reduction ratio and throughput, ensuring that hard stones are efficiently crushed into specified sizes. Primary Jaw Crushers: Stationary fixed or modular designs with hydraulic adjustment, handling up to ~500 t/h. Robust kinematics and large feed openings ensure reliable primary reduction. Secondary/Primary Impact Crushers: High-power rotor crushers applying high impact force for secondary crushing. These units minimize fines and material loss, thanks to Herbie technology that prolongs wear part life. Energy-efficient drive systems cut power use while maintaining throughput. Tertiary (Fine) Impact Crushers: Polygonmachine’s Tertiary HSI units are built for fine crushing and shaping of hard ores. They use high-speed rotors and replaceable blow bars to generate precise, cubical aggregate shapes. Capacities range up to ~350 t/h, and interchangeable chambers allow processing of limestone, basalt, and various ores with consistent results. Cone Crushers: For highly abrasive ores, Polygonmachine offers multistage cone crushers to achieve uniform size at very high reduction ratios technical specs vary by model. Screening Equipment Screening is critical to classify crushed material into required size fractions. Polygonmachine offers heavy-duty vibrating screens in a variety of configurations (inclined, horizontal, multi-deck) to suit different applications. These screens separate oversize chunks for re-crushing and deliver uniform products for final use. Each screen is engineered for high throughput and fine control of product gradation: Vibrating Deck Screens: Available in multi-deck formats (two, three, or more decks) to segregate stone into coarse, intermediate, and fine sizes. Polygonmach screen decks use high-strength steel frames and are designed for quick media changes. They achieve high G-forces to promote material stratification. Scalping Screens: Placed ahead of crushers, these robust screens (with heavy-duty grizzly bars or coarse mesh) remove fines and dirt, protecting primary crushers and improving overall plant efficiency. Inclined Screens: With steep angles and high amplitudes, these screens process large volumes and moisture-laden ores. Their welded box-section frames provide rigidity under heavy loads. Horizontal Screens: Used in secondary/tertiary stages, these screens maximize deck area and use vibration to achieve efficient classification at moderate feed grades. Sorting Equipment After initial crushing, sorting equipment refines the material stream by removing unwanted components. Polygonmachine’s sorting solutions are tailored to boost ore quality and throughput. Typical sorting and pre-concentration equipment includes: Magnetic Separators: Drum or plate magnets extract ferrous (iron) contaminants from rock and ores. By capturing tramp iron early, these units protect downstream equipment and improve concentrate purity. Air Classifiers and Density Separators: These systems separate particles by density or aerodynamic properties, eliminating dust and light impurities (like coal or coal dust from sand). Optical and Sensor Sorters (optional): In advanced applications, polygonmach can integrate sensor-based sorters that use X-ray or near-infrared detection to segregate high-value ore from waste. These machines can dramatically reduce the load on grinding circuits by pre-removing waste stone. Conveying Equipment Efficient material handling connects all stages of a mining plant. Polygonmach designs a range of conveying systems – from compact feeders to long-distance belts – to keep ore moving with minimal downtime. Key conveying components include: Belt Conveyors: Polygonmach supplies heavy-duty belt conveyors in widths up to 1,000 mm or more. A 1 m-wide belt at typical speeds (~1.3–2.0 m/s) can move roughly 200–320 t/h. Wide belts and long spans are available for linking remote crusher plants and stockpiles. Conveyors use robust pulleys and low-friction idlers to reduce power draw, and dust-tight skirtboards where needed. Electrically efficient motors and variable-frequency drives ensure smooth starts and controlled speed. Vibrating and Grizzly Feeders: Polygonmachine vibrating feeders regulate feed to crushers. Grizzly feeders also double as pre-screens, allowing fine material to bypass the crusher. These feeders are constructed of heavy plate steel to handle shock loads, and they come with adjustable decks to match feed size distributions. Telescopic and Radial Conveyors: For loading conveyors or forming stockpiles, Polygonmachine offers telescopic conveyor extensions and radial conveyors (see Stacking Equipment below). Telescopic belts can extend/retract to reach different heights and vehicles, improving flexibility on-site. Washing and Classifying Equipment Washing equipment cleans ore and aggregate, removing clay, sand, and other contaminants. Polygonmachine wash plants are built for high cleaning efficiency and low water consumption. Major washing components include: Log and Rotator Washers: These agitate and scrub the material. Log washers use rotating “logs” inside a trough to break down clays and slimes. Spiral/Classifying Tanks: Combining gentle washing with classification, these circular tanks (often with multiple concentric spirals) remove very fine particles and rinse coarse sand. Polygonmachine classifiers return coarse sand to the spiral while overflow slurry carries the fines away for tailings. Vibratory Dewatering Screens: After washing, dewatering screens remove excess water. These screens vibrate fine sand so water drains through, discharging a much drier product. Industry-standard dewatering screens can reduce moisture content to around 8%. For example, a typical dewatering
