Stone Crusher 2000 Day: Throughput, Operating Costs, and Real-World Feasibility

When we talk about a “stone crusher 2000 day,” we are referring to a crushing plant designed to process approximately 2,000 metric tons of raw stone per day (assuming a standard 10-hour shift, that equals 200 tph). This article outlines the typical configuration required to hit that number, compares stationary versus mobile setups, reviews actual operating costs per ton, and presents a documented case from a hard-rock quarry in India. We also address common questions about power consumption, maintenance intervals, and whether a 2000-ton daily output is realistic for medium-sized contractors.

1. What Does “2000 Ton Per Day” Actually Mean in Plant Design?

A 2000 t/day crusher is not a single machine; it is a system. For a 10-hour working day, the plant must sustain 200 tons per hour (tph) with a 75–80% load factor. A typical configuration includes:

• Primary jaw crusher (e.g., 42x32 or equivalent) with a feed opening of 1050x750 mm, set at 100–125 mm closed side setting (CSS).
• Secondary cone crusher (e.g., 2200 series or HP300) for reduction from 150 mm to 40 mm.
• Tertiary VSI (vertical shaft impactor) for cubical final aggregates (20 mm, 10 mm, 6 mm).
• Screens – two or three decks (e.g., 2.4m x 6.0m) to separate fractions.
• Conveyors – total belt length typically 80–120 meters, with widths of 800–1000 mm.

The key metric is not just the crusher’s nameplate capacity, but the actual throughput after accounting for feed size distribution, moisture, and hardness. For basalt or granite with compressive strength above 200 MPa, you will lose 15–20% of rated capacity.

2. Stationary vs. Mobile: Which One Reaches 2000 t/day More Reliably?

Parameter	Stationary Plant	Mobile Plant (e.g., track-mounted jaw + cone)
Setup time	4–8 weeks (civil works, foundations)	2–3 days (no concrete, just level ground)
Daily throughput (10h)	2000–2200 t (stable)	1600–1800 t (due to frequent repositioning and refueling)
Power source	Grid electricity (0.08–0.12 USD/kWh)	Diesel (0.35–0.50 USD/liter)
Cost per ton (opex)	1.2–1.8 USD/t (including power, wear parts, labor)	2.5–3.5 USD/t (diesel alone is 40% of this)
Mobility	None – permanent site	Can move every 2–3 days to new face
Best for	Long-term quarry (5+ years)	Short-term projects or multiple small pits

Verdict: If you need 2000 t/day every single day for a year, a stationary plant is the only economically sound choice. A mobile plant will struggle to hit 2000 t/day consistently because every move costs 4–6 hours of downtime.

3. Real Case: 2000 t/day Hard Rock Plant in Maharashtra, India (2021)

A mid-sized contractor in Nashik district (Deccan Traps basalt) needed 2000 t/day of crushed aggregates for a 45 km highway project. They initially tried a mobile jaw + cone combo (Metso LT106 + LT300HP). After 3 months, average daily output was 1,720 tons, and diesel costs were eating 31% of revenue.

Solution implemented (stationary retrofit):

• Primary: Puzzolana 2215 jaw crusher (150 tph rated, set at 110 mm CSS)
• Secondary: Puzzolana 2200 cone (set at 35 mm CSS)
• Tertiary: Puzzolana VSI 900 (for 20 mm and 10 mm)
• Screens: 2 x 2.4m x 6.0m (three-deck)
• Power: 400 kVA grid connection (actual draw: 320–350 kW)

Results after 6 months (documented in project log):

• Average daily output: 2,140 tons (10.5-hour shift, including 45 min lunch)
• Power consumption: 0.85 kWh per ton (vs. 1.1 kWh/t for mobile diesel-electric)
• Wear parts cost: 0.42 USD/t (jaw plates lasted 210 hours, cone liners 180 hours)
• Total opex: 1.55 USD/t (including 6 operators, 2 loaders, 1 excavator)
• Payback period: 14 months (vs. 22 months for the mobile setup)

The key lesson: the stationary plant’s consistent feed rate (using a vibrating grizzly feeder with 80 mm pre-scalping) was the single biggest factor in hitting 2000 t/day. The mobile plant lost time every time the excavator had to wait for the crusher to clear a jam.

4. Critical Operating Parameters to Sustain 2000 t/day

• Feed control: Use a variable-speed apron feeder, not a manual chute. A 10% fluctuation in feed rate drops throughput by 15% due to chamber packing.
• CSS monitoring: Check the jaw crusher’s CSS every 4 hours. A 5 mm increase in CSS reduces output by 8% and increases flakiness index by 12%.
• Moisture limit: If feed moisture exceeds 5%, screens will blind. Use a wet screen (water spray) or pre-dry the feed – otherwise, output drops to 1,400 t/day.
• Belt speed: Conveyors should run at 1.5–1.8 m/s. Slower belts cause material buildup at transfer points, which stops the entire line.

5. FAQ – Common Questions on 2000 t/day Stone Crushers

Q1: Can a single jaw crusher handle 2000 t/day without a secondary?
No. A jaw crusher with a 200 tph rating (e.g., 48x42) can produce 2000 t/day only if the final product is allowed to be 150–200 mm (coarse rubble). For standard aggregates (20 mm, 10 mm), you need a cone or VSI. The jaw alone will produce 60% oversize material, which must be recirculated – that effectively halves your throughput.

Q2: What is the minimum power requirement for a 2000 t/day plant?
For a stationary plant with jaw + cone + VSI + screens, you need 350–400 kW of connected load. That translates to a 500 kVA transformer (at 0.8 power factor). If you run on diesel generators, you need two 250 kVA gensets in parallel – but fuel cost will be 0.18–0.22 USD per ton just for power.

Q3: How many operators are needed for a 2000 t/day plant?
Typically 5–6 per shift: 1 control room operator, 1 loader operator (feeding the hopper), 1 excavator operator (at the quarry face), 1 maintenance fitter, and 1 electrician. If you have a remote monitoring system (SCADA), you can reduce this to 4.

Q4: What is the typical wear life for crusher parts at 2000 t/day?
For basalt (abrasiveness index 0.25–0.35):

• Jaw plates (fixed + swing): 180–220 hours (about 9–11 days at 20 h/day)
• Cone liners (mantle + concave): 150–180 hours
• VSI rotor tips: 60–80 hours
• Screen mesh (polyurethane): 400–600 hours
  Budget for wear parts at 0.35–0.50 USD per ton of crushed material.

Q5: Is it better to run 20 hours/day at 100 tph or 10 hours/day at 200 tph?
Run 10 hours at 200 tph. Reason: At 100 tph, the crusher operates at 50% load, which increases specific wear (per ton) by 20% because the chamber is not fully packed. Also, labor and overhead costs are fixed – running 20 hours doubles your labor cost per ton. Only exception: if you have cheap night-shift labor and expensive daytime electricity.

6. Conclusion – Is 2000 t/day Feasible for You?

Yes, but only if you have:

• A consistent feed source (quarry or recycled concrete) with at least 2,200 tons of blasted rock available per day.
• A stationary plant (or a semi-mobile with a fixed primary).
• Grid power (diesel will kill your margins).
• A maintenance plan that includes daily inspection of wear parts and weekly liner rotation.

If you are a contractor with a 6-month project, a mobile plant at 1,600 t/day might be acceptable. But for any operation longer than 12 months, the stationary 2000 t/day configuration pays for itself in 14–18 months, purely on fuel and wear savings. The numbers above are based on actual field data from Indian and Southeast Asian hard-rock quarries – not theoretical brochures.
