Market situation of crushing screening shaping and sand making in gravel aggregate mines in 2020

Sand aggregate is the largest, irreplaceable and indispensable material for infrastructure construction such as buildings, roads, bridges, water conservancy, hydropower and so on, which is closely related to the survival and development of human beings.

In order to construct and transform the world, tens of billions of tons of aggregate are consumed every year, which is the second largest natural resource after water.

At the beginning of 2020, ten departments including the Ministry of industry and information technology, the national development and Reform Commission, the Ministry of natural resources and the Ministry of ecological environment jointly issued several opinions on promoting the high-quality development of machine-made sand and stone industry, proposing to strive to form a relatively perfect and reasonable mechanism sand and stone supply guarantee system by 2025, with a substantial increase in the proportion of high-quality machine-made sand and stone, and an annual output of 10 million tons or more of super large-scale The production capacity of machine-made sand and stone enterprises accounts for 40%, and the proportion of machine-made sand and gravel produced by using tailings and waste rock has increased significantly.

The industry believes that this is China's first guidance on the development of the sand and gravel industry, which will promote China's gravel industry into a new era of high-quality development.

In addition, in recent years, the aggregate downstream demand continues to stimulate, and the overall scale of China's gravel industry continues to expand. It is predicted that the growth rate of the market scale this year will be slower than that of last year, but the expansion of the market scale is still inevitable.

In 2020, the output value of sand and stone industry will reach 1546.74 billion yuan!

The production of sand and gravel aggregate is mainly divided into mining, crushing, screening and shaping sand production. The crushing equipment is mainly divided into two categories according to the working principle: one is extrusion crushing equipment, such as jaw crusher, gyratory crusher, cone crusher, etc., which is suitable for crushing raw materials with high abrasion index.

The stone powder content in the products is low, but generally the broken materials have many needle and flake particles and poor pumping performance; the other is impact crushing equipment, such as impact crushing Machine, hammer crusher and vertical shaft impact crusher are characterized by large material crushing ratio, simple structure, convenient equipment maintenance, good product grain shape and small material compressive strength loss.

In large aggregate production line, jaw crusher or gyratory crusher is usually used for coarse crushing, while cone crusher, impact crusher or hammer crusher are used for intermediate crushing.

It is understood that the output of sand and gravel in the first half of 2020 will be 6.236 billion tons, a decrease of 22.3% compared with the first half of 2019. Mainly affected by the epidemic situation in the first half of 2020, the operating rate of gravel aggregate enterprises decreased, and the sand and stone market demand was not effectively released, so the sand and gravel production decreased significantly compared with the first half of 2019.

The production capacity of manufactured sand will be released in the second quarter of 2020 and concentrated in the third quarter of 2020. Therefore, it is estimated that the national sand and gravel production will increase by 4.17% in 2020, and the output is expected to reach 20 billion tons.

According to the survey on the aggregate demand of 267 mixing plant enterprises in China by Centennial construction network, it is known that the aggregate demand in the second half of the year is 103.5% higher than that in the first half of 2020.

Among them, natural sand demand increased by 58.76%; manufactured sand demand increased by 97.43%; gravel demand increased by 154.4%, with the largest growth rate.

The development trend of gravel aggregate is better, which will stimulate the demand of crushing equipment to a certain extent. Will the demand, price and profit of crushing equipment rise in 2020?
