Slag Grinding Plant

1. The bulk slag materials is crushed by the jaw crusher, then it will be sent to the storage bin by the bucket elevator. 
2. Next, the material is evenly, quantitatively and continuously sent to the slag grinding mill by the electromagnetic vibrating feeder.
3.  After grinding, under the action of blowing, all slag materials will be sent to the powder separator for sorting, the unqualified powder after sorting falls back to continue grinding, and the qualified fine powder is sent to the storage bin through the pipeline.
4. finally the finished slag powder is output through the discharge valve.

Slag grinding plant equipment

The complete set of equipment is mainly composed of jaw crusher, bucket elevator, cement silo, vibrating feeder, slag mill, fan, powder collector, bag filter, etc.

1. Crushing equipment

The slag needs to be crushed into small sizes. Commonly used crushing equipment includes jaw crusher, impact crusher, cone crusher, and slag mobile crushing plant.

2. Grinding equipment

At present, it has become the mainstream trend in the building materials industry to replace the amount of cement in concrete and cement products with slag micro powder. One of the main equipment in the slag powder production line is the slag mill.

There are so many types of cement mills that can be selected for slag grinding plants.

Vertical mills are generally used for grinding slag powder. A vertical cement mill is also called a vertical slag mill. It has the advantages of high production capacity, low energy consumption, and environmental protection in the field of slag powder grinding.

The vertical cement mill of AGICO CEMENT is inseparable from the following points:

• High degree of automation: The vertical slag mill adopts PLC automatic control, which can be controlled remotely.
• Stable operation: The equipment adopts a grinding roller and disc device, and the operation is relatively stable.
• Easy maintenance: the slag vertical mill has good wear resistance, and the grinding roller and disc lining plate are made of special materials. The equipment has a long service life and is easy to maintain.
• Good particle shape of the finished product: the powder ground by the vertical slag mill is better in terms of whiteness and purity.

In addition to the vertical slag mill, other types of cement mill that can grind slag powder include: cement ball mill, pre-grinding cement roller press, and cement roller press for final grinding. For slag grinding plant, ball mill generally causes problems of dust accumulation, low grinding efficiency and high grinding temperature. The particle size and gradation distribution of the finished product are not as good as those of the vertical mill in the cement roller press grinding.

3. Other cement equipment

As for separators, centrifugal separator and cyclone separator are not suitable for producing slag fine powder, because these two types of separators are used to produce slag fine powder with a high specific surface area, the separation efficiency is too Low, the cycle load rate is too large, which is uneconomical, swirl separator can be considered.
