As a common solid waste, the coal gangue recycling is conducive to enhance the comprehensive utilization value of coal gangue. What equipment is better for grinding gangue? The vertical roller mill production line recommended by HCMilling(Guilin Hongcheng) has scientific technological process. We will provide scientific allocation and selection scheme to create value for coal gangue grinding production line.




1. Introduction and Comprehensive Utilization Of Coal Gangue

Coal gangue is the solid waste discharged in the process of coal mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation.


Recovery of coal and pyrite: The good coal is washed out from the gangue through the simple process, the inferior coal is selected from the gangue through screening, and the pyrite is picked out at the same time.


 For power generation:

It mainly uses coal washing and gangue washing to produce electricity. China has used a mixture of coal and gangue (about 2000 kcal /kg) to generate electricity. Slag can produce slag brick and slag cement.


Building materials:

Instead of clay, it can be used as the raw material of brick making and less good farmland can be dug. When burning bricks, coal can be saved by using the combustibles of coal gangue itself.


What kind of grinding mill can be used to grind gangue? HCMilling(Guilin Hongcheng) is a professional grinding mill manufacturer, which is a favored equipment supplier in the field of coal gangue grinding. Our vertical roller mill equipment meets the requirements of energy conservation and emission reduction, and has attracted much attention in the industrial solid waste industry. It has gradually become an exclusive grinding mill equipment. The following are its main advantages and features.


2.Technological Process Of Coal Gangue Vertical Roller Mill  

Vertical roller mill is specialized in grinding coal mine, cement industry, slag, coal gangue, steel slag, water slag, non-metallic ore and other markets. Its technological process mainly includes crushing, grinding, grading and powder collection. The bulk material is milled into the required feed size by the crusher, and the material moves around the grinding plate and enters the grinding roller table. Under the pressure of the grinding roller, the material is constantly squeezed, ground, cut and crushed. After grinding, the material is blown by high-speed air flow, and the coarse-grained material is blown back to the grinding plate for grinding again. At the same time, the suspended materials can be dried, and the fine powder can be graded by the grader, and the qualified powder can be collected by the dust collection system to become the finished product.


As a professional mill supplier that creates value for industrial solid waste, HCMilling(Guilin Hongcheng) always pays attention to the comprehensive utilization prospect and development direction of solid waste. In the field of coal gangue grinding, vertical roller mill equipment is high-output, efficient, environmentally friendly and energy-saving. And the whole production line process is scientific, you are welcome to come to the factory to know the details of coal gangue vertical roller mill equipment.
