港口散粉状物料卸船仓储中转工艺技术介绍

当前随着国民经济的发展，大型水泥制造企业不断涌现。水泥销售市场的半径不断延伸，水泥粉料中转站这一新生事物伴随着经济发展的大潮出现在经济发达的沿海、沿江、沿河城市和各大港口。

With the development of the national economy, large cement manufacturing enterprises are constantly emerging. Cement sales market has extended the radius. The new thing of cement powder transfer station appears in the economically developed coastal, river, river city and major port with the tide of economic development

水泥粉料中转站的总体规划（General plan of cement powder transfer station）：

一、选址（site selection）

1.1、因为水泥市场需求量大，水泥粉料中转站一般选址在经济较发达的沿海、沿江、沿河地区。
1.2、百公里半径没有大型的水泥生产企业或当地水泥制造企业没有能力控制和垄断水泥市场价格。
1.3、水泥粉料中转站最经济的物流工具是船舶，选址最佳位置在千吨或万吨级码头，这决定了企业今后的运输成本。

1.1、Because of the high cement market demand , cement powder transfer station is usually located in the economically developed coastal areas, along the river, along the river area.
1.2、There’s no cement production scale enterprise in hundred kilometer radius or the local cement manufacturing enterprises do not have the ability to control and monopolize the market prices of cement.
1.3、The most economical logistics tools for cement powder transfer station is the ship, so the best selection is in kiloton or million ton dock. This determines the transportation costs in the future.
