Stationary plants are fixed installations combining feeders, primary and secondary crushers, and multi-deck screens into one layout. They handle massive feed sizes and deliver very high throughputs (typically hundreds up to ~1,000 tons/hour). A typical stationary plant uses a heavy-duty primary jaw crusher (e.g. 1500×1300 mm feed opening) followed by impact or cone crushers for finer sizing. These plants run continuously for long-term operations (mining, quarrying, infrastructure) and produce cubical aggregate and sand. Key advantages include rugged design, high capacity, and consistent, high-quality product. Maintenance features often include hydraulic access to liners and automation for setting adjustment.

| Parameter | Specification |
|---|---|
| Plant throughput | 100 – 1,000 t/h (configurable; highest models reach ~1,000 t/h) |
| Primary crusher feed opening | up to 1,500 × 1,300 mm (jaw type) |
| Secondary crusher max feed | ≈300–600 mm (impact or cone crusher) |
| Aggregate drive power | Several hundred kW (e.g. ~200–500 kW motors on major crushers) |
Mobile plants mount feeders, crushers, screens and conveyors on tracks or wheels, offering full portability. They are ideal for short-term sites or projects with multiple locations. Capacities typically range from tens to several hundreds of tons per hour. For example, a mobile jaw plant with a 1200×750 mm jaw can crush up to 400 t/h on tracks, while larger mobile impact or cone plants can reach 500–700 t/h. Mobile plants use diesel-driven engines (~200–300 kW) to power hydraulics and crushers, providing off-grid flexibility. They adapt quickly to new sites and reduce hauling costs. Key advantages include rapid setup (plug-and-play), versatility (can include washing units), and complete systems on a single chassis.
| Parameter | Specification |
|---|---|
| Feed capacity | 50 – 700 t/h (mobile jaw and impact plants) |
| Typical mobile jaw | 1,200 × 750 mm feed opening, up to ~400 t/h |
| Engine power | ~200–300 kW diesel (driving crusher hydraulics and aux) |
| Dimensions (transport) | Length ~14–16 m, width ~3 m, height ~3–4 m (varies by model) |
| Weight (approx.) | 30–50 ton (large tracked units) |
Primary impact crushers (horizontal-shaft impactors) accept very large feed (often >800 mm) and crush in one stage. They are used when a high reduction ratio and cubical product are desired. Typical models handle feed sizes up to ~1 m, producing 100–1,200 t/h depending on rotor size. For example, one primary HSI model (PM6490) has a 40″ (≈1,000 mm) feed, 700–1,200 t/h capacity and a 700–1,000 HP drive. Primary HSIs feature thick rotor and housing liners, quick-access doors for maintenance, and hydraulic apron adjustment. They excel in quarrying and recycling where oversize stone must be crushed in a single pass. Advantages include one-step reduction (eliminating extra crushers), low operating cost per ton, and very uniform, cubical output.
| Parameter | Specification |
|---|---|
| Feed opening | Up to ~1,000 mm (e.g. 40″ rotor throw) |
| Capacity | ~100 – 1,200 t/h (model-dependent) |
| Rotor diameter | ~900 – 1,250 mm (36″ – 50″) |
| Drive power | 75 – 750 HP (60 – 560 kW) (larger units in hundreds of HP) |
| Reduction ratio | Up to ~20:1 |
Secondary HSIs further reduce primary crusher product, shaping aggregates. They typically handle medium-size feed (up to 350–600 mm) and output 150–600 t/h. For instance, one series offers 150–250 t/h on a 350 mm feed, and up to 380–600 t/h on a larger 1,000 mm feed. Secondary impactors produce highly cubical material (ideal for asphalt/concrete), often reducing/eliminating the need for a tertiary stage. Many have two counter-hammer aprons with spring or hydraulic adjustment. Their advantages include high reduction ratio in one pass, modular cast liners for easy change-out, and flexible rotor configurations. They are widely used on low to medium hardness rock (limestone, concrete, slag) where cubicality is critical.
| Parameter | Specification |
|---|---|
| Feed opening | ~350 – 1,000 mm (varies by model) |
| Capacity | ~150 – 600 t/h (depending on model and feed density) |
| Rotor diameter | ~1,120 – 1,530 mm |
| Motor power | ~160 – 500 kW |
| Final product size | Typically 0–80 mm (cubic aggregate) |
Tertiary impact crushers produce fine sand and chippings from feed under ~150 mm. They generate very fine gradations (0–½″) with minimal oversize. Throughputs are lower – up to ~160 t/h as reported for one design at maximum feed. Tertiary HSIs have multiple blow bar rows (often 4) and high G-forces to pulverize material. Two rotor configurations are common: a 2-row rotor (feed up to ~70 mm, for sand) and a 4-row rotor (feed up to ~150 mm, for chippings). Benefits include tight size control and very cubical fines. They excel in producing high-quality manufactured sand or specialty aggregates. Key advantages: uniform gradation (even on sticky feeds), adjustable stroke for fine-tuning output, and fully replaceable wear parts designed for long life.
| Parameter | Specification |
|---|---|
| Feed size (max) | ~70 mm (sand rotor) or ~150 mm (chipping rotor) |
| Throughput | Up to ~160 t/h (fine product) |
| Blow bar rows | 2–4 (rotor-dependent) |
| Output product size | Down to 0.5–2 mm (very fine aggregate) |
| Drive power | Typically 150–300 kW |
VSI crushers use high-speed rotors to “throw” rock against anvils or rock bed, producing cubical sand and aggregates. They run at high RPM with fine feeds (typically <100 mm) and give high fines content. Capacities range roughly 15–250 t/h for common models. For example, one vertical impactor with 3″ feed does 50–100 t/h, and a larger (4″ feed) unit reaches 100–250 t/. VSI crushers require less horsepower per ton than comparable cone crushers. They have no sieves or grizzlies, relying solely on impact – making them robust for sticky or abrasive feeds. Key advantages: consistently cubical product shape, high proportion of fines (useful for sand production), and capability to recirculate scats for sand-size output. They are ideal for tertiary/sand-making roles where maximum shape is required.
| Parameter | Specification |
|---|---|
| Feed size (max) | ~40–50 mm (1–2″) |
| Capacity | ~15 – 250 t/h (model-dependent) |
| Rotor speed | High (e.g. 1500–1800 RPM typical) |
| Motor power | Up to ~300–400 HP (225–300 kW) |
| Output gradation | High sand content (flat, cubical particles) |
Cone crushers provide efficient secondary or tertiary reduction on hard rock. They use a rotating eccentrically mounted mantle within a concave bowl to crush by compression. Capacities are very wide (tens to >1,500 t/h) and feed size up to several hundred millimeters (e.g. 250–430 mm depending on model). For example, a large cone (PM870) can do ~208–1,370 t/h, with a 350 mm feed opening and a 600 kW motor. Cone crushers run at slow speeds, giving high crushing forces. They produce a relatively fine and consistent product, often used in high-output quarries. Advantages include high capacity, low operating cost per ton, good stone shape, and hydraulic adjustments/clearing. They handle abrasive materials well. Typical applications: aggregate, concrete/asphalt production, mining (ore flotation feed), and wherever fines control is needed.
| Parameter | Specification |
|---|---|
| Capacity | ~150 – 1,800 t/h (varies by series; up to ~1,800 t/h on largest models) |
| Feed opening | ~125 – 428 mm (5–17″ typical; larger models) |
| Closed side setting | ~3 – 50 mm (adjustable for product gradation) |
| Drive power | 330 – 750 kW (up to ~1,000 HP) |
| Product gradation | Medium-to-fine (0–50 mm, cubical aggregate) |
Jaw crushers are heavy-duty machines used for primary crushing of very hard or abrasive materials. A jaw crusher has a fixed and a moving plate; material is crushed by compression between them. Stationary models (as above) and mobile units exist. For instance, a stationary PTJ106 jaw (1500×1300 mm) yields 480–1,160 t/h. A mobile tracked jaw (e.g. POLYGONMACHİNE PTJ175) with a 1,200×750 mm feed can achieve ~400 t/h. Typical jaw crushers have low-speed, robust design to handle heavy loads. Advantages: very large feed capacity, simple steady feed control, and ability to crush extremely hard rock. They are ideal as primary crushers in quarrying and mining. Features often include hydraulic adjustment of the discharge setting and overload relief to protect the crusher from tramp iron.
| Parameter | Specification |
|---|---|
| Feed opening | ~700 – 1,500 mm (e.g. 1200×750 mm mobile; 1500×1300 mm stationary) |
| Capacity | ~400 – 1,200 t/h (mobile to large stationary) |
| Stroke/min | ~200–300 (slow-acting for coarse crushing) |
| Drive power | ~200–500 kW (diesel engine on mobiles; electric on stationary) |
| Weight | ~25–50 ton (mobile); larger for fixed plant crushers |
Polygonmachinery offers multi-deck vibrating screens in both inclined and horizontal configurations. Inclined screens typically have 2–4 decks set at 10–25°, giving high throughput (up to ~1,620 t/h on large units) and effective separation of multiple products. Horizontal (flat) screens operate at 0° to save headroom, using high-G vibrators to move material. Triple-shaft horizontal screens have three counter-rotating shafts that deliver an oval stroke; these screens excel at screening fine material and have lower blinding risk. One modern triple-shaft design offers up to 6.5 g acceleration and is suitable for wet or dry sticky feeds. Screens handle a wide range of materials (sand, gravel, crushed rock, recycled concrete) and settings. Applications range from scalping (removing fines) to final sizing of aggregates. Advantages include precise sizing, modular deck replacements, and in horizontal types a very consistent fine cut due to uniform screen tension.
| Parameter | Specification |
|---|---|
| Screening area | Up to ~20+ m² (multi-deck) |
| Capacity | ~30 – 1,620 t/h (depending on size and deck count) |
| Decks | 2–5 (inclined); 1–3 (horizontal triple-shaft) |
| Deck inclination | ~0° (horizontal) or 10–25° (inclined) |
| G-force | ~3–6 g (triple-shaft screens) |
These are specialized screens where three shafts under the screen box create a high-energy elliptical motion. The triple-shaft design spreads the load and allows higher g-forces (up to ~6.5 g) for aggressive screening. These screens are compact (low profile) and handle fine-to-medium screening without plugging. They are ideal for portable or stationary plants requiring fine sand/aggregate production. Benefits include easy adjustment of stroke and stroke angle for different materials, robust welded construction, and simple deck removal. Polygonmachinery’s triple-shaft screens ensure extremely fine separation and can replace conventional vibrating screens with minimal modifications.
| Parameter | Specification |
|---|---|
| Number of shafts | 3 |
| Stroke adjustment | Yes (stroke length and angle) |
| G-force | Up to ~6.5×g |
| Screen inclination | ~0° (flat) |
| Typical capacity (single unit) | ~50–300 t/h (model-dependent) |
Polygonmachinery vibrating feeders evenly meter lump material from the hopper into crushers. Grizzly feeders have bars in the floor to remove fines upstream. Capacities range from a few hundred up to >2,000 t/h for large double-shaft grizzlies. Our feeders are robust (heavy-duty drive, geared shafts in oil bath) and come in multiple widths and lengths. A standard grizzly feeder might be 1×3–1×4 m in size and handle feed sizes up to 1,500 mm. Fine undersize passes through the grizzly, reducing crusher wear. Advantages: gentle, continuous feed, ability to pre-screen out fines, rugged steel construction, and quick maintenance. Control features include adjustable vibrator speed. These feeders are used in both primary and secondary stages to ensure smooth crusher loading.
| Parameter | Specification |
|---|---|
| Feed capacity | ~170 – 2,040 t/h (varies by model) |
| Bar spacing (grizzly) | Typically 50–150 mm (removes <50–150 mm material) |
| Hopper volume | 30–200 m³ (standard units) |
| Drive power | ~30–100 kW (single or dual vibrator motors) |
| Feed size | up to ~1,500 mm blocks |
| Weight | 4–30+ t (depending on size) |
For high-capacity lines, prescreeners incorporate a short grizzly under the hopper. Oversize goes to the crusher while fines bypass. This boosts overall circuit efficiency. Polygonmachinery’s prescreen feeders can process large feed up to 800 mm and divert up to 30%+ of fines. Key benefit: reduces unnecessary crushing of sand and gravel, improving throughput and reducing wear.
Feeding hoppers (loading bunkers) are large bins that receive blasted rock or recycled concrete. Ours are sized (e.g. 10–30 m³) to bridge to wheel loaders or conveyors. At the hopper base a vibrating feeder or a belt conveyor provides precise flow to the crusher. Dosing conveyors (variable-speed belts) meter material rate under automated control. Typical hopper data: 10–30 m³ volume, dual-vibrator drives (3–4 kW each), dimensions ~2–4 m wide×1–4 m long. Advantages include steady feed, overload protection, and front-loading capability. Hoppers are engineered heavy-duty (thick steel plating, replaceable liners) and may be fitted to mobile or fixed plants. Dosing belts allow automated, uniform feed rates into crushers, which stabilizes the crushing process and optimizes throughput.
| Parameter | Specification |
|---|---|
| Hopper volume | 10–30 m³ (standard models) |
| Base feeder drive power | 2×1.5–2 kW (vibrators) |
| Hopper dimensions (approx) | 2.4×3×1.2 m up to 3×4×2.5 m |
| Dosing conveyor width | 500–1,000 mm (customized for feed rate needs) |
| Dosing conveyor speed | Adjustable (e.g. 0–2 m/s) for precise metering |
| Feed rate control | From a few t/h up to ~100+ t/h (belt depend.) |
Polygonmachinery’s telescopic stackers are versatile radial belt conveyors that build stockpiles efficiently. They extend telescopically and rotate (radial movement) to create conical or trapezoidal piles. Leading models reach up to ~58 m length (190 ft) fully extended. Their high loading capacity (up to ~3,000 t/h) means large stockpiles are built quickly. Key advantages: fully automated operation (PLC control), remote radio control, and large stockpile volume (≈30% more material on same footprint vs. fixed conveyors). The radial design reduces material segregation and achieves uniform pile shape. Stackers can be fixed or towable, with optional diesel generator for standalone power. They are used in mining yards, ports, and any operation needing organized storage of crushed aggregate or other bulk material. Benefits include eliminating front-end loader stacking (saving labor), preserving material quality, and simple fold-up for transport.
| Parameter | Specification |
|---|---|
| Max. reach (extended) | ~58 m (190 ft) |
| Rotation range | Typically 180–360° (radial swing) |
| Loading rate | Up to ~3,000 t/h |
| Stockpile height | ~15–25 m (site-dependent) |
| Drive power | Diesel engine (e.g. 50–150 kW) or electric, gearbox drive |
| Mobility | Fixed or mobile (track/wheel-mounted options) |
Besides radial stackers, Polygonmachinery provides straight telescopic belt conveyors that extend/retract to load trucks or bins. These allow discharge length up to 30 m+ without repositioning the feeder. They have similar telescoping mechanics and belt drives. Advantages: fast, continuous loading of vehicles, eliminating stockpile step. They include features like dust covers and hydraulic extension.
