Environmental protection, energy saving (intelligence), large-scale become the three major elements of sand aggregate production line

For a long time, sand mining in natural river has caused sand and stone resources to dry up, water source pollution, river embankment safety and so on. In recent years, with the increase of policy to limit the production of natural sand and stone resources, mechanism sand has ushered in unprecedented development opportunities, and has gradually become the main source of sand and stone aggregates for construction. However, for a long time, the mechanism sand industry has been scattered, chaotic and poor, which has brought great obstacles to the good development of the mechanism sand industry.

According to the data, China has become the largest producer and consumer of sand and stone in the world, with an annual output of 20 billion tons.

For a long time, natural river sand mining has caused problems such as depletion of sand and stone resources, water source pollution, and the safety of river embankment.

However, for a long time, the mechanism sand industry has been scattered, chaotic and poor, which has brought great obstacles to the good development of the mechanism sand industry. For this reason, at the beginning of this year, the Raw Materials Department of the Ministry of Industry and Information Technology publicly solicited some opinions on promoting the high quality development of the sand and stone industry of the mechanism (draft for consultation).

"Opinions> put forward that by 2025, the quality assurance system of the sand and gravel is basically improved, and the proportion of the high-quality mechanism represented by the mechanism sand I products is continuously improved; most of the county-level administrative district layout construction serves the local sand and stone processing base or the distribution center;" The production concentration of sand and stone enterprises with an annual output of more than 5 million tons and above is up to 25%, and the yield of sand and stone, such as tailings, building wastes and stone materials, is up to 30%. The energy consumption (excluding mine production and sewage treatment) of ten thousand tons of product energy consumption (excluding mine production and sewage treatment) of the new and expansion mechanism sand and stone enterprise is not higher than 10 tons of standard coal (with the soft rock such as limestone as the raw material) or not higher than 13 The amount of water consumption is not higher than 1400 tons, and the non-road transportation material accounts for 30%, and the demonstration enterprises that are more intelligent, green, high in quality and good in management are cultivated in tons of standard coal (including hard rock in granite and the like), the water consumption is not higher than 1400 tons, and the non-road transportation material accounts for 30%.


In the past, the production capacity of sand and stone enterprises was relatively small, usually the daily output was 400 tons, and there were some problems, such as the difficulty of dust and water pollution control, serious pollution and so on. Today, after recent rectification, the daily output of 6000 tons or even tens of thousands of tons of sand and stone production lines are gradually becoming the mainstream in the industry. At the same time, under the background of environmental high pressure, dust pollution and water pollution control have become the core problems that must be solved from the beginning of the construction of sand and stone aggregate production line.

According to public reports, in recent years, the domestic governments at all levels of the sand industry rectification efforts are indeed increasing. According to the data, under the background of promoting the construction of ecological civilization, various localities have issued policies to close and eliminate traditional sand and stone enterprises. In 2013, 56000 sand and stone enterprises with mining rights over the national scale were reduced to 17000 by the end of 2017. More sand and stone companies closed last year, and to some extent led to a shortage of supplies in the sand market.

in that long run, It is of great significance for the green and sustainable development of the sand and stone industry or the technical upgrading of the equipment industry.

In the past 2018, the enterprise has developed a second "spring", thanks to the enterprise's efforts in large-scale equipment, EPC and technology upgrading. The disorderly development of the sand industry in the past, not only caused more serious resource waste and environmental pollution, but also caused the equipment manufacturing enterprises to be irregular due to the low equipment requirements and small production scale.


With the continued increase of the country's investment in infrastructure construction and the steady and steady development of the economy, the demand of the mechanism sand and stone will continue to show the trend of continuous growth. As the equipment supplier, the double-flow stone-stone machine has also been environment-friendly, efficient and large-scale as the core direction of the product upgrade. In recent years, the large number of EPC projects undertaken by the Jinshi Machinery in China have also been highly recognized by the Owner in terms of environmental protection and energy consumption.
