Sea sand refers to granular material formed by seawater erosion and transportation. It is often used as an important raw material in construction and civil engineering. In recent years, with the continuous expansion of the global construction industry and infrastructure construction, the market demand for sea sand has been growing day by day, and due to restrictions on land-based sand mining, the market prospects for sea sand are very broad.

This project aims to build a sea sand production line with an annual output of 2 million cubic meters to meet the growing market demand for sea sand while contributing to local economic development. This article will introduce the market analysis, technical solutions, investment scale and expected returns of this project.

market analysis

The continuous expansion of the global construction industry and infrastructure construction has led to an increasing demand for sea sand, and due to restrictions on land-based sand mining, the market prospects for sea sand are very broad. According to market research institutions, the global sea sand market will continue to expand in the next few years. It is expected that by 2030, the global sea sand market will reach more than 15 billion US dollars.

As for the Chinese market, China’s construction industry and infrastructure construction are developing rapidly, and the market demand for sea sand is also growing. However, because the process of sand mining causes great damage to the environment and ecology, the government has imposed restrictions on land-based sand mining in recent years, resulting in sea sand becoming an important raw material in the construction industry and infrastructure construction.

Technical solution

The technical solution for this project is to use a wet sea sand separation process, which is divided into the following steps:

1. Sea sand pretreatment: Clean, screen and remove impurities from the collected sea sand to ensure that the quality of the sea sand meets production requirements.

2. Sea sand grinding: Send sea sand into grinding equipment for crushing and fine grinding to obtain sea sand minerals of a certain particle size.

3. Sea sand sorting: Wet sea sand sorting technology is used to sort sea sand minerals and classify them according to characteristics such as density and color of sand grains to obtain sea sand that meets the requirements.

4. Sea sand drying: dry the sorted sea sand to reduce the moisture content.
