How much it costs to open a sand and gravel factory depends on the production demand, scale and configuration of the production line. Generally speaking, the investment of a sand and gravel factory is between 800 million and 5 million. The specific fund analysis is as follows:

1. Reasonable design of sand production line is the key point of investment. Different manufacturers have different equipment models, configurations, materials selection and output, and their quotations are also different. The quotation of equipment on the market now ranges from tens of thousands to hundreds of thousands.

When purchasing sand-making equipment, we should reasonably combine different sand-making equipment according to our own production demand, output and scale. Reasonable selection of sand making equipment can reduce the investment cost.

2. Pre-audit process of basic investment, site rent, power labor cost, sand-making material cost, transportation cost, etc. It is the basic investment to open a sand factory, and these expenses are essential. Because the sand production line involves a lot of expenses, the specific expenses also depend on the user's site scale, production demand, equipment purchase and so on.
