Project overview

In recent years, with the rapid development of China’s economy and the acceleration of urbanization, the construction industry has increased its demand for construction raw materials, especially sand and gravel aggregates. As the basic raw material for construction, roads, bridges and other projects, sand and gravel aggregate has broad application prospects in the market. As an important province in China’s economic and transportation development, Henan Province has a growing demand for sand and gravel aggregates.

This project plans to invest 60 million yuan in Henan Province to build a sand and gravel aggregate production line with an annual output of more than 1 million tons. After the project is put into operation, it will effectively solve the bottleneck of demand for sand and gravel aggregates in the market, while promoting the economic development of Henan Province, promoting local employment, and providing high-quality raw materials for various infrastructure construction.

Project background

With the continuous expansion of my country’s infrastructure construction, especially the continuous advancement of highways, railways, residential buildings, commercial real estate and other projects, the demand for sand and gravel aggregates has increased sharply. As a transportation hub and a major economic province in central China, Henan Province has a huge demand for sand and gravel aggregates. According to industry forecasts, the sand and gravel aggregate market in Henan Province will continue to maintain rapid growth in the next few years.

However, due to the protection of the natural environment, the scarcity of sand and gravel resources, and the limitations of traditional mining techniques, the supply of sand and gravel resources has become an important factor restricting project construction. In order to solve this problem, Henan Province has proposed a strategic plan to build a green and intelligent sand and gravel aggregate production line.

Market analysis

1. Market demand

Sand and gravel aggregates are the basis of important materials such as concrete, asphalt mixtures and civil engineering. With the rapid economic development, especially in recent years, the demand for infrastructure construction such as roads, residential buildings, and commercial projects in Henan Province has surged, and the demand for sand and gravel aggregates has continued to rise. According to market research data, it is expected that the demand for sand and gravel aggregates in Henan Province will increase by 5%-8% annually in the next five years.

2. Policy support

The Henan Provincial Government has been committed to promoting environmental protection and sustainable development, and has introduced a series of policies and measures to encourage the construction of green, environmentally friendly, and efficient production lines. Therefore, this project will benefit from policy support, and through measures such as energy conservation, emission reduction, and environmental protection management, it will comply with the concept of green development and receive active policy support.

3. Market competition

At present, there are some sand and gravel production enterprises in Henan Province, mainly focusing on traditional artificial sand mining and preliminary processing stages. However, most of these companies have problems such as aging equipment, low production efficiency, and substandard environmental protection. Through the introduction of modern equipment and intelligent production management, the new generation sand and gravel aggregate production line project can provide higher quality and more efficient production capabilities, and has strong market competitiveness.

Project investment scale and funding arrangements

The total planned investment for this project is 60 million yuan, which will be mainly used for equipment procurement, factory construction, and environmental protection facility construction. The specific funding arrangements are as follows:

1. Equipment procurement

Equipment procurement is the main capital expenditure of this project, and the estimated procurement cost is approximately RMB 25 million. The main equipment includes: jaw crusher, cone crusher, vibrating screen, sand washing machine, conveyor, drying equipment, etc.

2. Factory construction

The factory construction of this project includes factory buildings, office buildings, staff dormitories, warehousing and other facilities. The budget for factory construction is 15 million yuan.

3. Environmental protection facility construction

The construction of environmental protection facilities is one of the key points of the project, with an estimated investment of 10 million yuan. Environmental protection facilities include wastewater treatment, exhaust gas emission, dust prevention and control systems, and comply with national and local environmental protection standards.

4. Working capital

The working capital budget is RMB 10 million, which is mainly used for raw material procurement, production operations and market expansion.

5. Project construction cycle

The construction period of the project is expected to be 12 months, and the plan is divided into four stages: planning, construction, equipment installation and commissioning.

Technical solution

1. Crushing technology

This project uses advanced crushing technology, including jaw crushers and cone crushers. The jaw crusher is mainly used for coarse crushing of raw materials, which can effectively break large stones; the cone crusher is used for medium and fine crushing to ensure uniform particle size of the aggregate to meet the needs of different customers.

2. Screening technology

High-efficiency vibrating screens and rotary vibrating screens are used to screen aggregates. Through the precision screening device, the distribution of aggregates of different particle sizes can be accurately controlled to ensure the stability of product quality.

3. Sand washing technology

The sand washing machine is an important piece of equipment for this project. It adopts a fully enclosed design to effectively reduce water pollution, while efficiently removing soil and impurities from the sand and gravel to ensure that the quality of the sand and gravel aggregate meets national standards.

4. Environmental technology

This project will strictly comply with national environmental protection requirements and invest in the construction of wastewater treatment facilities, exhaust gas emission treatment systems and noise isolation facilities to minimize environmental pollution during the production process. By using modern dust removal equipment and circulating water systems, the project is ensured to be green and environmentally friendly.

The sand and gravel aggregate project with an annual production capacity of more than one million tons is a project with broad market prospects and good social benefits. Through reasonable capital investment, advanced production technology and environmental protection measures, the project will meet market demand, promote local economic development, create social employment, and at the same time contribute to the green and sustainable development of the industry.
