Background

    With the rapid economic development, the continuous expansion of the scale of urban construction, increasing need for building sand and gravel, the original natural gravel obviously cannot meet the demand, therefore, to seize the initiative, China's sand industry, especially artificial sand manufacturing and gravel production line, are developing in an accelerated speed. At present, the market price of artificial sand 30 yuan / ton, in addition to pre-investment in equipment and wear parts consumption in the production process, it basically needs no other funds. With seizing the opportunity and spotting the prospect, Henan Xinmi Guozhuang stone plant introduces two large gravel aggregates production lines.

Analysis

    1. Process design: The 500T/H gravel production line of Xinmi Guozhuang Stone plant mainly adopts the combined crushing technique with two hammer crushers of Dingli. The closed-loop system formed not only increases the hourly capacity but also guarantees the crushing degree of the aggregates is within the required size range for the particles. In order to ensure the cleanliness of aggregates, the vibrating feeder with the function of soil removing is adopted in the feeding end, which is the first channel; in the back end, the finished materials in line with the application requirements are screened through the screening equipment with reasonable configuration. Compared with the traditional process of combining jaw crusher with impact crusher, the process using the above equipment has the advantages of light installed capacity, convenient maintenance, less investment and quick effect, and the finished aggregate particles have good shape, high cleanliness and high strength, etc.

    2. Production & installation: it totally takes 2 months to complete the entire production line since Nov 3, 2010 when the contract was signed. The whole procedure includes the process design of entire production line, equipment manufacturing & installation and the final enabling of standard operating procedures.

    3. Investment return: the estimated investment of this production line is less than RMB 5 million. Now it has been put into production and operation. With annually production of fine gravel aggregates of 2 million Ton, it is predicated the full investment can be recovered within half year with outstanding economic efficiency.
