Scoria/scoriae/slag detailed introduction

From:未知    Date:2015-10-30 16:06

Nowadays, scoria/slag is widely used in industrial production, cement production and newborn energy production.What is scoria/scoriae/slag? How many moh hardness scoria/scoriae/slag has? Do you know its uses and hazards? How about the scoria/scoriae/slag grinding technology? And how to choose the suitable slag powder grinding mill machine according to your needs?
 
Scoria/scoriae/slag definition:
1. scoria/scoriae also known as leaching slag. Uranium ore (or concentrate) in acid or alkali leaching leaching process is a part of the acid or alkali leaching minerals.
2.  A glassy substance when molten slag is quenched.

Scoria/scoriae/slag composition and structure
Acidic slag contains more SiO2, alkaline slag contains more Al2O3 and CaO. Because slag itself has a certain hydraulic, it is not suitable for long-term storage.
 
Scoria/scoriae/slag uses and hazards
Slag plays an important role in industrial production, especially in some major factories. By using of slag, we refine and process slag cement, slag powder, slag wool, blast furnace slag, granulated blast furnace slag, copper slag,In addition, blast furnace slag can be used as raw material of cast stone, glass, fertilizer, enamel, ceramic, etc.Also, due to the large number of mining, not only leads to lack of space underground, easy to cause earthquakes, and slag for certain air pollution, for many years in the mine staff also easily lead to respiratory diseases by slag.
 
Scoria/scoriae/slag grinding technology
1. slag grinding with clinker, gypsum;
2. slag grinding alone, then with clinker, gypsum powder mixed into the cement;
3. pre-grinding slag alone, then with clinker, gypsum grinding together. However, because the use of the first grinding mill technology when the slag is easy to focus on the meal, since only the role of mixed materials.
 
Scoria/scoriae/slag powder grinding mill machine
Generally, for grinding scoria/slag, the capacity need more than  5/h to meet the practical needs. In grinding field, there are 2 kinds of powder grinding mill that are widely used. 

Firt one is the large vertical grinding mill, the capacity can get 10-400 t/h, but the fineness can only get 30-400 mesh. 
The other one is ultrafine vertical powder grinding mill, the fineness can get 30-2500 mesh adjusted, but the capacity only can get 1-30 t/h.
