【Product description】: GRMSS steel slag vertical roller mill made by CHAENG is special equipment for grinding industrial waste steel slag into powder. CHAENG steel slag vertical mill has complete models and strengthens the iron dressing process, with the feeding size of ≤ 5mm.
【Product capacity】: 200,000-1,500,000t/a
【Specific surface area】: 450~500 m²/kg
【System power consumption】: ≤50 kWh/t
1. One set of system is enough, low operating costs
2. The power consumption of vertical mill system is 20% lower than ball mill
3. Low dust pollution
4. High iron separation rate, improving economic efficiency
5. Advanced slag discharge belt, to reduce the wear of grinding roller
6. Finished fineness can be guaranteed at 480-500m2/kg
The materials fall to the central of grinding table through the blanking pipe, then the grinding table is rotating at the constant speed and disperses and spreads out the materials evenly with the aid of centrifugal force, which makes the grinding table become the material bed with a certain thickness. Then several grinding rollers on the grinding table grind and crush the materials at the same time. With the continuous centrifugal force, the materials constantly move toward the outer edge of the grinding table. When the materials which leave the grinding table meet the hot gas which enter into the mill through wind ring, the materials will also rise. Then the materials enter into the separator through the mill’s middle shell, during this process, the materials and the hot gas have sufficiently heat exchange with each other, and the water is quickly evaporated. The powder separator controls the size of the finished products, particles which are larger than the specified size will be separated and fall back into the grinding table, and particles that meet the fineness requirement will enter into the finished products warehouse through the powder separator.

It is a two-purpose Production Line with two parts. One is a steel slag production line with annual capacity of 300,000 million tons slag powder, and the other one is a GGBFS production line with annum capacity of 1.2 million tons GGBFS. The main grinding equipment is designed with 2 GRMS vertical roller mills and 1 steel slag ball mill. All of the technical operation can be controlled in DCS Room, which is the most advanced level technology in the world. Baosteel visited us for the A check in April, 2014. All the device and equipment including vertical mill, electric cabinet, accessories, etc. are all qualified as they required.
