The slag is used to the concrete projects, such as projects involving in roads and bridges, which have higher requirements for bending strength. Meanwhile, the slag also suits to make concrete with high strength and high performance .The two advantages following of slag make it having great superiority in the big scale concrete projects, underground concrete projects and sea concrete projects.

3.Features

The Slag Grinding Plant used the most advanced vertical mill system up to now. Different with the technology used in the conventional slag vertical mill system in the market, CHAENG (Xinxiang Great Wall Machinery Co., Ltd) has innovated many new technology which ensure that the whole granulated blast furnace slag production can operation stably with high capacity, high efficiency ,low carbon.Its new process is mainly the following aspects:

1.Separation of dry material and wet material

2.The outside cycle using bury scraping machine and hauling engine and pipe iron remover combination

3.Set up steady flow storehouse ( middle storehouse )

4.The waster material will be send to the vertical mill going through the outside warehouse

5.Set the dust collector on the chute transportation corridor

6.Using two gate valve to replace 3-way valve which has a high failure rate.

7.The large pieces of slag will be crushed again and again.

8.Add the iron choosing machine to make a better separation effect of slag and iron

9.Other creative industrial technique

    2. Vertical Roller Mill for slag slag vertical mill is the equipment to grind Ground Granulated Blast furnace Slag into small particles. In China, quality slag (fineness:4200-4500cm2/g) produced by vertical roller mills are being used to substitute clinker in conventional cement manufacturing as well as to partially replace OPC for ready-mixed concrete production.
