Faced with the shortage of sand and gravel, some people are happy and others are worried. I am happy about the huge profits of machine-made sand, but I am worried that the production of machine-made sand is not easy. Many people's impression of machine-made sand still stays in the past, and only a few people can make money. Now as long as they go through all the formal procedures, they can start a stone factory, and how much money they earn depends on the construction of the sand production line.

1. sand excavation procedures: procedures for processing stone into sand: name verification of industrial and commercial department, application for business license, application for mining report of land and resources, application for mining license, approval of safety supervision bureau, environmental protection bureau's environmental assessment of sand excavation site, and tax department's handling of tax registration certificate. Because different regions have different requirements, you should consult the relevant local departments for details.

2. Equipment required by a sand mining field: A complete sand production line covers vibrating feeders, crushers, sand makers, vibrating screens, sand washers, belt conveyors and other equipment, with simple technology and large return on investment. The common raw materials of machine-made sand are river pebbles, pebbles and limestone, which can be used in various construction industries.

1. Vibrating feeder can be a conveying device that provides materials for sand making equipment, and is usually used for feeding operation of crusher;

2. Crushers include primary crushing and secondary crushing. Jaw crusher is usually used for primary crushing, and cone crusher or impact crusher is used for secondary crushing.

3. The sand making machine can finely crush and shape the crushed stones to ensure the uniform particle size of the finished sand. Usually, the impact sand maker is used, which has a large output;

4. Sand and gravel will produce certain dust in the production process, so it is necessary to configure a sand washer to clean the sand and gravel. Generally, a wheeled sand washer, a spiral sand washer or a three-in-one sand washer is used;

5. The vibrating screen is used to screen and classify the sand and gravel, so as to screen out stones with different specifications;

6. Belt conveyor is a bridge connecting all kinds of sand making equipment.

3. How much does it cost to run a sand mining field? The capital cost of investment battlefield is mainly divided into four parts. Generally speaking, the expenses for formalities, venue lease, equipment purchase, manpower and water and electricity are about1~ 30,000. According to local conditions, the cost of equipment purchase is about 8 million to 2 million, and the cost of manpower and water is tens of thousands of yuan every month. Roughly speaking, the investment of construction waste treatment plant is more than1000000 yuan.

If the above answers are useful to you, please encourage me to praise me so that I can help more people. Thank you!
