PE750x1060 Jaw Crusher
The standard configuration for an aggregate production line with an hourly output of 200 tons is: ZSW490×110 grizzly feeder → PE750×1060 jaw crusher (primary crushing) → secondary crushing (medium/fine) → 4YK2160 four-deck circular vibrating screen (closed-circuit classification), yielding four finished product sizes (0–5, 5–10, 10–20, and 20–31.5 mm) in a single pass. The PE750×1060 model is the anchor of this line: it features a 750×1060 mm feed opening, accepts a maximum feed size of ≤630 mm, and has a rated capacity of 110–320 t/h. A 200 t/h target places it in the mid-range rather than at the upper limit—a crucial distinction between a system that can run continuously at full capacity and one that falls short of production targets from day one. There are only two real pitfalls: sizing the secondary crushing stage based on finished product output rather than throughput (the secondary crusher and screen in this line must handle 235 t/h, not 200 t/h), and mistaking the nameplate capacity for the actual operational capacity when processing hard rock.
I. Equipment Selection: Why the 750×1060 is the Anchor for a 200 t/h Aggregate Line
The primary crusher model is selected based on the maximum lump size of the raw ore, not simply by tonnage: the jaw crusher's feed opening width must be at least 1.18 times the maximum raw ore size (calculated as: max lump size &pide; 0.85). If this ratio is insufficient, large lumps will bridge across the feed opening, causing actual capacity to plummet by half—this is the root cause of the most common quarry complaint: "The equipment isn't broken, yet production output just won't go up."
| Model | Feed Opening (mm) | Max. Feed Size (mm) | Rated Capacity (t/h) | Motor (kW) | Positioning for the 200 t/h Class |
|---|---|---|---|---|---|
| PE600×900 | 600×900 | ≤500 | 90–180 | 55–75 | Rated upper limit is the target; hard rock adjustment leaves only 72–144 t/h. |
| PE750×1060 | 750×1060 | ≤630 | 110–320 | 90–110 | Mid-range selection; still covers 200 t/h after adjustment. |
| PE900×1200 | 900×1200 | ≤750 | 200–400 | 132 | Running at the lower limit to meet the target; frame, foundation, and controls are spec'd for 400 t/h, resulting in over-investment. |
For the PE600×900, the capacity drops to 72–144 t/h after applying the 0.8x hard-rock factor—meaning it falls short of production targets from day one. For the PE900×1200, running at the 200 t/h lower limit means the extra money spent on the frame, foundation, and controls yields no additional tonnage. The 750×1060 is the only model in this class that avoids both "maxing out" and "wasteful over-spec'ing."
The first piece of auxiliary equipment is the feeder: ZSW490×110 (trough 4900×1100 mm, max. feed ≤580 mm, 180–400 t/h, 15 kW). Its grizzly bar section bypasses fines and soil into a separate pile, reducing the jaw crusher's unproductive load at the source. Its feeding capacity offers a twofold margin over the 200 t/h requirement, meaning a wheel loader can discharge directly into the hopper without the need for a dedicated intermediate surge bin.

II. Model Selection: Three Calculations
The model for a 200 t/h aggregate production line is determined through calculation, not by simply looking up a chart.
① Primary crushing is determined by the maximum feed size: For raw ore ≤530 mm, select the PE750×1060 (feed opening: 750×1060 mm; max. feed size: ≤630 mm; discharge opening: 80–140 mm; rated capacity: 110–320 t/h; power: 110 kW). Adjusted for rock hardness, the capacity becomes 99–288 t/h for medium-soft rock and 88–256 t/h for hard rock; the 200 t/h target falls comfortably in the middle range, avoiding operation at the equipment's limits.
② Secondary crushing is determined by throughput, not final product output: Assuming an oversize rate (material retained on the screen) of 15%, the actual throughput for the secondary stage is 200 &pide; 0.85 ≈ 235 t/h. This is the step where equipment mismatch is most likely to occur—if the secondary stage is sized for only 200 t/h, post-commissioning issues will include fluctuating product pass rates, drastically reduced lifespans for liners and blow bars, and high bearing temperatures in the screening equipment.
③ Screening equipment is also sized based on throughput: The 4YK2160 model (screen deck: 2100×6000 mm; four decks) handles the 235 t/h load, with the four screen decks corresponding to four product size fractions. The load per unit of screen area is 235 &pide; (2.1×6.0) ≈ 18.7 t/(h·m²), placing it in the upper range of the standard 15–20 t/(h·m²) limit. Together, these figures indicate that neither the screen area nor the number of decks can be reduced.
III. Secondary Stage Selection: One Line, Two Branch Options—Determined by Material Abrasiveness
The choice between an impact crusher and a cone crusher for the secondary stage depends on the material properties, not the budget.
| Category | Medium-Soft Rock Branch: PF1315 Impact Crusher | Hard Rock Branch: HP300 Multi-Cylinder Cone Crusher |
|---|---|---|
| Applicable Materials | Limestone, dolomite, river pebbles, shale (compressive strength ≤150 MPa; low abrasiveness) | Granite, basalt, iron ore, metamorphic sandstone (compressive strength 150–350 MPa; high abrasiveness) |
| Key Parameters | Rotor Φ1320×1500 mm; max feed ≤350 mm; rated capacity 100–280 t/h; 220 kW | Moving cone Φ1120 mm (44″); max feed ≤241 mm; discharge opening 10–45 mm; rated capacity 125–485 t/h; 220 kW |
| Adjusted for Operating Conditions | ×0.9 → 90–252 t/h; covers 235 t/h throughput (7% margin) | ×0.8 → 100–388 t/h; covers 235 t/h throughput (>60% margin) |
| Crushing Principle | Impact crushing; high yield of finished product in a single pass | Inter-particle (lamination) crushing; relies on material-on-material grinding |
| Product Shape | High cubicity, low needle/flake content; suitable for asphalt surface courses | Needle/flake content ≤12%; continuous gradation |
| Initial Investment | 30%–40% lower than cone crushers for equivalent capacity | Higher |
| Wear Part Lifespan | Blow bars last only 120–200 hours when processing granite | Bowl liner/mantle last 1,200–2,000 hours |
| Conclusion | Economical solution for limestone and dolomite aggregate lines | Long-term solution for granite and basalt aggregate lines |
Two points must be clarified:
1. The 7% margin for the impact crusher means it is "sufficient," not "abundant." If the oversize rate rises to 25%, the required throughput capacity becomes 200 &pide; 0.75 = 267 t/h. ...t/h, which exceeds the adjusted upper limit of 252 t/h for the PF1315; in this case, it is necessary to upgrade to the PF1320 (160–350 t/h). This is not a matter of whether the equipment selection is conservative or not, but rather a question of the stability of the raw ore gradation.
2. The capacity margin in the hard rock branch may appear wasteful, but it is actually insufficient. While the HP300’s adjusted range of 100–388 t/h seems to offer plenty of headroom for a 235 t/h throughput, fluctuations in rock hardness directly consume capacity: compressive strength can vary by as much as 30% between different benches of the same ore body, and that margin serves as a buffer to absorb such fluctuations.

IV. Overall Line Configuration: Closed-loop circulation determines particle shape and load
The process flow is: Raw ore bin → ZSW490×110 feeder (grizzly bar pre-screening; fines and soil are bypassed to a separate pile) → PE750×1060 primary crushing to ≤160mm → B800 conveyor to secondary (medium/fine) crushing → B800 conveyor to 4YK2160 screen → Oversized material returned to the secondary crusher via B650 conveyor, forming a closed loop.

| Primary Crushing | Jaw Crusher | PE750×1060 | Feed opening 750×1060mm; Max feed ≤630mm; Discharge opening 80–140mm; 110–320 t/h | 110 kW |

Based on a median value of 37 kW for the screen: Total installed power for the medium-soft rock line is approx. 15 + 110 + 200 + 37 ≈ 360 kW; for the hard rock line, it is 15 + 110 + 220 + 37 ≈ 380 kW. Specific energy consumption is approx. 1.2–1.6 kWh/t (including conveying and dust collection; estimated value). Motors are customized for local voltage (380/400/440V) and frequency (50/60Hz).
Why recirculate material instead of simply enlarging the screen mesh to let it pass through in one go? The price difference for aggregates depends not on output volume, but on particle shape. Jaw crushing involves single-stage compression, resulting in a high proportion of flaky and elongated particles; by sending oversize material back to the secondary stage for another round of impact or inter-particle crushing, the content of flaky and elongated particles drops significantly, and over-crushing remains controllable. This meets the requirements of concrete mixing plants for 5–10mm and 10–20mm... Gradation is the most critical factor; it determines whether the finished product can enter high-value markets, such as asphalt surface courses. The trade-off is the load on the screen deck: due to the recirculation of material, the actual load on the secondary stage and the screening machine is 15%–20% higher than in an open-circuit configuration.
| Product Size Fraction | Typical Application |
|---|---|
| 0–5mm | Manufactured sand feedstock, plastering mortar |
| 5–10mm | Fine aggregate for concrete, asphalt surface course |
| 10–20mm | Primary concrete aggregate |
| 20–31.5mm | Mass concrete, roadbed cushion layer |
One final question: Should this line be mobile? If the quarry site is fixed, the service life exceeds three years, and minimizing cost-per-ton is the priority, choose a stationary plant. If quarry sites are dispersed, the project schedule is tight, and frequent relocation is required, use a two-unit mobile combination (mobile jaw crusher station + mobile secondary screening station) instead.
V. FAQ
Q1: Does the "200-ton" aggregate production line rating refer to nominal capacity or actual operational capacity?
A1: The figures in the table are nominal values, calibrated based on limestone (bulk density approx. 1.6 t/m³). Actual operational capacity is calculated by multiplying the nominal value by 0.85–0.95 for medium-soft rock and 0.75–0.85 for hard rock; actual output also fluctuates based on raw material gradation, moisture content, and the product size mix. A 10%–15% margin should be allowed for nominal values; acceptance testing should be based on measured continuous hourly output rather than the nameplate figure.
Q2: Should a secondary crusher be an impact crusher or a cone crusher?
A2: It depends on material abrasiveness. For limestone, dolomite, river pebbles, and shale, choose the PF1315 impact crusher; for the same capacity, the investment cost is 30%–40% lower than a cone crusher, and it produces good particle shape suitable for asphalt surface courses. For granite, basalt, iron ore, and metamorphic sandstone, choose the HP300 multi-cylinder cone crusher; it utilizes inter-particle (lamination) crushing, and the wear parts have a service life 6–10 times longer than impact crusher blow bars. ...times. When using an impact crusher for granite, the blow bar lifespan is only 120–200 hours; the frequency of downtime would quickly erode profits.
Q3: Why are the secondary crusher and screen sized for 235 t/h instead of 200 t/h?
A3: Because of the closed-circuit material return. With an oversize rate (material retained on the screen) estimated at 15%, the secondary crusher and screen must handle the "200 t/h finished product + returned material," calculated as 200 &pide; 0.85 ≈ 235 t/h. If sized for only 200 t/h, both units would face long-term overloading after commissioning, resulting in fluctuating product quality, high screen bearing temperatures, and drastically reduced lifespans for liners and screen meshes. If the oversize rate rises to 25%, the throughput becomes 267 t/h, necessitating an upgrade from the PF1315 to the PF1320 model for the medium-soft rock line.
Q4: What are the feed requirements for the 750×1060 jaw crusher?
A4: The maximum feed size is ≤630mm; raw stones with a diameter of approximately 600mm can be fed directly, but anything larger requires pre-crushing to prevent chamber jamming. A ZSW490×110 grizzly feeder is used for uniform feeding and pre-screening to remove soil; if the clay content is consistently high, a soil removal step should be added at the feed end rather than relying on downstream remediation. Metal foreign objects (such as drill rods or anchor bolts) must not enter the machine; installing an iron remover on the feed conveyor belt is recommended.
Q5: If we want to expand capacity to 300 t/h in the future, what provisions should be made now?
A5: You only need to make provisions in three areas—there is no need to spend extra money right now:
① Design the jaw crusher foundation to accommodate the PE900×1200 model to avoid having to break up the foundation later;
② Reserve a foundation spot and electrical control circuit for a second crusher at the secondary crushing stage;
③ The screening plant layout should provide space and conveyor connection points for the future installation of a second circular vibrating screen. Belt conveyor widths should not be selected at the absolute limit; for instance, a B800 specification should allow for a future increase in operating speed.
