Calculating the cost per ton of crushing and screening stone involves several steps and considerations. Here's a general outline to help you determine the cost:
1. Determine the Total Cost
Fixed Costs:
Variable Costs:
-
Operating Costs:
- Fuel or electricity
- Labor (operators, maintenance staff)
- Wear and tear (repair and maintenance)
- Consumables (blades, liners, etc.)
-
Material Costs:
- Raw material (if it's not your own quarry)
Indirect Costs:
- Administrative Costs:
- Insurance
- Permitting and compliance costs
- Overhead costs
2. Calculate the Total Throughput
- Estimate the total amount of stone processed over a specific period (daily, monthly, or annually). This can be given in tons per hour (TPH).
3. Aggregate Total Tons Produced
- Multiply the daily throughput by the number of working days to get the total produced in a specific period (e.g., monthly or yearly).
4. Compute the Cost Per Ton
Use the formula:
\[ \text{Cost per Ton} = \frac{\text{Total Fixed Costs} + \text{Total Variable Costs} + \text{Total Indirect Costs}}{\text{Total Tons Produced}} \]
Example Calculation
-
Determining Costs Over a Year (assuming all values are annual):
- Fixed Costs: $100,000 (capital equipment)
- Variable Costs: $50,000 (operating and maintenance costs)
- Indirect Costs: $20,000 (administrative and compliance)
-
Total Cost:
- Total Cost = Fixed Costs + Variable Costs + Indirect Costs
- Total Cost = $100,000 + $50,000 + $20,000 = $170,000
-
Total Tons Produced:
- Suppose the plant operates 300 days a year and processes 500 tons per day.
- Total Tons Produced = 300 days * 500 tons/day = 150,000 tons
-
Cost per Ton Calculation:
- Cost per Ton = Total Cost / Total Tons Produced
- Cost per Ton = $170,000 / 150,000 tons = $1.13 per ton
Conclusion
By following these steps and ensuring you have accurate data, you can determine the cost per ton of crushing and screening stone for your specific operation. The accuracy of your costs and throughput estimates will significantly impact the reliability of your cost per ton calculation.
