200 TPH Granite Cone Crushing Production Line
For a granite cone crushing production line with an hourly capacity of 200 tons, only one primary configuration is viable: ZSW1100×4200 grizzly feeder → PE750×1060 jaw crusher (primary crushing) → CS220 cone crusher (secondary/tertiary crushing) → 4YK2470 four-deck circular vibrating screen (closed-circuit classification). This setup yields four finished product sizes (0–5, 5–10, 10–20, and 20–40 mm) in a single pass, with oversize material returned to the cone crusher via a return conveyor. Given granite's high abrasiveness, a secondary impact crusher is not a viable option; the only remaining decision is whether to use the CS220 or the HPC300 cone crusher.
Display of Finished Crushed Granite Products
I. Four key granite metrics explain why the "jaw crusher + cone crusher" configuration was chosen:
Compressive strength (100–250 MPa): A hard, brittle rock; primary crushing requires inter-particle (lamination) crushing, and the secondary stage must allow for a 20%–30% capacity margin.
• Mohs hardness (6–7) and quartz content (20%–40%): Liners are the major consumable cost in secondary/tertiary crushing—impact crusher blow bars require replacement on a weekly basis, whereas cone crusher liners last for months.
• Bulk density (2.6–2.8 t/m³): Granite throughput is 15%–25% lower than limestone at the same power level; nominal capacity ratings must be multiplied by 0.75–0.85 to determine actual operational output.
• Low water absorption (0.1%–0.4%) and high crushing ratio: Finished products can be supplied directly to concrete mixing plants without drying, though the proportion of flaky/elongated particles tends to be high, necessitating closed-circuit recycling for shape improvement.
Two easily overlooked factors: The surface weathered layer has significantly lower strength and high clay content, requiring separate mining and crushing from fresh rock; abrasiveness—not hardness—is the primary driver of per-ton costs, as quartz content dictates annual liner consumption.
II. Standard Configuration for a Granite Cone Crushing Production Line (200 t/h Capacity)
Hopper and Feeding: Receiving hopper (LC3000×4000) equipped with a ZSW1100×4200 grizzly feeder (15 kW; rated capacity 200–430 t/h; adjustable grizzly bar spacing). Fines and soil (≤80 mm) are bypassed and stockpiled via a B500×10m conveyor (B-5).
Primary Crushing: PE750×1060 jaw crusher (110 kW; feed opening 750×1060 mm; max. feed size 630 mm; discharge setting 60–150 mm; rated capacity 110–380 t/h). Operating with a wider discharge setting meets the rated requirement of 250 t/h for the secondary stage, providing sufficient processing margin for the subsequent medium-fine crushing stage of the granite line.
Medium-Fine Crushing: CS220 cone crusher (220 kW; crushing cone diameter 1400 mm / 4½ ft; discharge setting 19–40 mm; rated capacity 130–260 t/h). Inter-particle (lamination) crushing is the only viable method for the secondary crushing stage of granite.
Screening and Closed-Circuit Operation: 4YK2470 four-deck circular vibrating screen (45 kW; screen surface 7000×2400 mm; rated capacity 180–900 t/h) separates the material into four finished product grades in a single pass, with four B650×15m conveyors (B-4) transporting them to stockpiles. Oversized material is returned to the cone crusher for re-crushing via a B800×21m return conveyor (B-3), establishing a closed-circuit process.
Conveyors B1000×23m (B-2) and B1000×16m (B-1) handle the main material flow.

Installed power for main equipment: 390 kW; 8 belt conveyors arranged at lengths of 10–23 m (estimated 3–7.5 kW per unit), bringing total line installed power to approx. 415–450 kW; actual operating load is approx. 70%–80% of installed capacity; calculated at 200 t/h, specific energy consumption is approx. 1.5–1.8 kWh/t (including conveying).
III. The only real dilemma for this granite cone crushing line: CS220 or HPC300?
Both feature 220kW motors, but differ in structure and crushing chamber design:
CS220 Cone Crusher
CS220 (Spring-type): Fine chamber discharge setting 19–40mm, max feed size 100mm, rated capacity 130–260 t/h; simple structure, affordable spare parts, no reliance on a hydraulic station, but requires machine stoppage to adjust the discharge setting.
Hydraulic Cone Crusher
HPC300 (Multi-cylinder hydraulic): Capacities range from 145–445 t/h depending on the chamber (EC, C, M, or F) at 220kW; features one-touch discharge setting adjustment, automatic pressure relief for uncrushable objects (tramp iron), automatic liner wear compensation, and produces a lower percentage of flaky/elongated particles.
How to choose: If the raw material source is stable and the budget is tight → CS220 is sufficient; invest the savings in wear parts. If the raw material source fluctuates, clay content is high during the rainy season, continuous operation despite tramp iron is required, or the product is destined for C50+ grade commercial concrete → Choose HPC300; the price difference is recouped through reduced downtime and lower flake/elongation rates.
IV. Three rules of thumb to determine if this granite cone crushing line can truly achieve a full 200 t/h output:
① Jaw crusher feed opening width ≥ 1.1–1.2 times the maximum raw ore size: The PE750×1060 has a 750mm feed opening, capable of handling raw ore up to 630mm; anything larger requires secondary blasting or a hydraulic breaker.
② Cone crusher rated capacity ≥ Target capacity &pide; 0.8: 200 &pide; 0.8 = 250 t/h, which falls within the upper end of the CS220’s rated range (130–260 t/h).
③ Screening area includes a 2x safety margin: Closed-circuit material recirculation increases the load on the screen deck by an additional 20%–35%; the 4YK2470’s rated capacity of 180–900 t/h accounts for this requirement.
Capacity Note: The 200 t/h figure in the table represents nominal capacity; acceptance testing is based on an actual operational throughput of 200 t/h.
V. FAQ (5 Questions)
Here are the five most frequently asked questions regarding the purchase of this granite cone crushing production line.
Q1: Why must a cone crusher be used for the secondary crushing stage in a 200 t/h granite line? Why not an impact crusher?
A1: Granite has high quartz content and is highly abrasive. Impact crushers rely on high-speed impact from blow bars, requiring replacement on a weekly basis, whereas cone crushers utilize inter-particle (layer) crushing, allowing liner lifespans to be measured in months. You should calculate the annual cost of wear parts based on the rock sample's abrasiveness index and compare this against the difference in equipment purchase costs.
Q2: To simultaneously produce four finished product sizes (0–5, 5–10, 10–20, and 20–40 mm), what should the cone crusher's discharge setting (CSS) be?
A2: The aperture of the top screen deck determines the maximum finished product size. To produce the 0–40 mm range, the CS220 discharge setting should be adjusted to 30–40 mm (adjustable range: 19–40 mm); oversized material is returned to the cone crusher via the B800×21m return conveyor for further crushing in a closed circuit.
Q3: Does the nominal 200 t/h rating refer to nominal capacity or actual operational capacity?
A3: Nominal capacity is rated based on medium-hardness limestone; given granite's bulk density of 2.6–2.8 t/m³, the actual operational capacity is approximately 75%–85% of the rated value.
Q4: What is the approximate investment cost for a production line like this?
A4: Investment costs vary significantly depending on the level of automation, the material of wear parts, and electrical standards (380V/50Hz, 400V/50Hz, or 60Hz); any "flat-rate" quote is unreliable. We recommend requesting an itemized quotation and conducting a Total Cost of Ownership (TCO) comparison based on equipment price, annual wear-part costs, and electricity expenses.
Q5: How should the production line be modified for raw materials with high clay content or for operations during the rainy season?
A5: The ZSW1100×4200 features a grizzly bar design with adjustable lower-deck spacing; fines and soil (≤80mm) are perted via a B500×10m bypass conveyor to a separate stockpile, preventing material clogging in the cone crusher. Anti-clogging polyurethane screen media can be installed. If the final product requires a clay content of <1%, a wheel-bucket sand washer and a fine sand recovery unit should be added downstream of the product discharge conveyor.
