With the rapid development of social economy and urbanization construction, the demand for sand and gravel is increasing day by day. However, the relevant departments have issued a large-scale ban on the exploitation of natural river sand, which has caused natural sand to be far from meeting market demand. Therefore, cobblestones have gradually become the darling of the machine-made sand market, and many practitioners in the sandstone industry have turned their attention to the production of high-quality cobblestone aggregates. As we all know, the stock of pebbles is relatively large, and it is more convenient to mine. The application of a pebble sand production line with complete certificates and qualified environmental protection can realize the value benefit of pebble sand production. So, what is the quality of sand made of pebbles? How big is the profit? The editor of Chongqing Longjian Group discussed with you.

1. How can sand made from pebbles not be checked?

1. Apply for complete certificates. Apply for a business license to the industry and commerce department, apply for a tax registration certificate, and submit an application report to the land and resources department. The land and resources department will examine and delineate the mining area for the mine and issue a mining license before operating. If it is a self-employed person, it is necessary to bring a personal ID card to the Industry and Commerce Bureau to apply for a pre-approval notice. At the same time, issue an EIA certificate to the Environmental Protection Bureau.

2. Purchase an environmentally friendly sand making equipment production line. One is to look at noise, and the other is to look at dust pollution. Therefore, when purchasing cobblestone sand making equipment, it is required that the starting noise and running noise of the sand making machine should meet the noise emission standards. At the same time, the exhaust system of the stone-breaking sand making equipment and the environmental protection dust collector are required to reduce the dust pollution in the production. Chongqing Longjian Group recommends a vertical axis plastic sand making machine, pulse bag dust collector, and requires everyone to grasp production in one hand and environmental protection in one hand.

What is the quality of cobblestone sand making?

Compared with natural cobblestones, the cobblestones have sharp edges and strong adhesion, and have good application effects. Its particle size is uniform and adjustable, and it can process a variety of graded aggregates without cracks, fine lines, and coarse and fine particles. It has stronger resistance to wear, corrosion, and impact. It has better durability and stable chemical properties in the house. Used in concrete, it can effectively enhance the workability and strength.

What is the profit of investing in cobblestone sand making and how much profit can be obtained? On the whole, the investment benefit is very good. At present, the average price of crushed stone in Chongqing is about 50 yuan per ton, and the average price of machined sand is about 60 yuan per ton. "The average price of crushed stone last year was 46.9~53.2 yuan/ton, and the average price of machine-made sand was 56~65.8 yuan/ton. Overall, the price was the same as that in 2019. However, if you want to make money in the sand factory, the first choice is Environmental protection. Therefore, when first selecting cobblestone sand equipment, we must fully consider the performance of the equipment. Chongqing Longjian Group tailor-made a full set of machine sand production line equipment for customers, strengthen the control of dust and noise, and clean the sand products , Recommend a more complete environmental protection configuration. For example: multi-function dust collection device, equipped with dust collection and dust suction equipment; humidification spray device, equipped with spray devices at key parts of screening, discharging, and feeding to reduce dust flying and reduce Dust pollution; waste water recovery device, equipped with sedimentation tank, to recycle and process the generated sewage, so as to create a green and environmentally friendly sand production line.
