How to calculate product cost of gravel processing factory?

The calculating of product cost is a nerve-wracking issue for the owner of a new gravel processing factory. When the gravel production line is allocated output, we can calculate the cost based on average minimum X t/h( For example, we have ten months for production per year, twenty-five days for production per month, max. twenty hours for production per day.)
