How much crushed stone can be produced from one cubic meter of rock? What is the production cost per ton of crushed stone?

Numerous measurement units are commonly used in crushed stone processing, serving as benchmarks for evaluating production efficiency. So, how much crushed stone can be produced from one cubic meter of rock? What is the production cost per ton of crushed stone? This article provides answers to these questions:

One cubic meter of stone refers to the measurement unit for large raw rock blocks. However, these large blocks must be processed into commonly used crushed stone specifications before use. Generally, transforming large stones into finished 05, 12, and 13 gravel requires multiple stages: primary crushing, secondary medium-fine crushing, and screening. Based on feedback from users across various regions, the typical yield rate is 80-90%. One cubic meter of rock yields 1.2 tons of aggregate (1–1.5 tons). Higher soil and impurity content in the raw rock reduces the yield rate.

Aggregate production costs primarily include machinery operation expenses, site fees, utilities, and labor costs. Typically, a small aggregate plant incurs approximately 20 yuan per ton in production costs. Currently, the market price for crushed stone is approximately 70 RMB per ton. After deducting raw material costs, material loss expenses, and operational expenses, the profit margin per ton ranges from 15 to 20 RMB. Based on this calculation, even a small-scale plant with an hourly output of 100 tons can achieve annual profits exceeding one million RMB. For larger-scale sand and gravel operations, profits may surpass ten million RMB. (All prices are in RMB. Specific figures vary by country and region and are for reference only.)
