Stone waste sand production feasible

Stone waste, including construction waste, stone crushing plant trimmings, etc., the amount of annual production is relatively large, they are not useless, after processing, can be turned into construction sand and gravel aggregates, is a good project with low cost and high income, compared with mining ore, it is lower investment and more convenient.

1. In terms of policy

At present, many provinces and cities are subsidizing the stone waste disposal project, the general subsidy program is as follows, each region's policy is different, for reference only, the specific please consult the relevant local departments:

a. Stone waste disposal projects can have a 30-year franchise;

b. Disposal of waste material subsidies of 2 yuan per ton, production land subsidy standards at 3 yuan / ㎡, the use of construction waste recycled concrete in the project to reach 10%, the full amount of construction waste disposal fees returned;

c. Water and electricity consumption is calculated at cost price;

d. During the construction period, the government provides financial support for national bonds and special funds for environmental protection.

Stone waste raw material acquisition cost is very low, coupled with the government subsidies for various funds, combined, the production cost can be said to be very low, the profit margin is very large.

2. From the stone waste itself

Stone waste itself is also a variety of stone and concrete, bricks, etc., after recycling and crushing, used as raw materials for construction sand is no problem at all, and not only can be made into sand, but also become recycled bricks, recycled concrete, recycled ready-mixed mortar, road bedding and so on.

Waste stone processing sand plant requires a complete set of crushing and sand making equipment, mainly jaw crusher, cone crusher, impact crusher, sand making machine, sand washer and other major equipment, and then configure the feeder, conveyor, vibrating screen and so on to form a complete production line to complete the demand from the large blocks of stone to the different particle size of the finished sand, but also can be configured with a mobile crushing production line, to deal with the operation of the different sites is more convenient. Convenient.
