The advantages of Liming Heavy Industry's slag mill production line

Slag refers to blast furnace slag from ironmaking. It is in a high-temperature molten state and rapidly cooled with water to form a granulated foam shape. It is milky white, light, crisp, porous, and easy to grind into fine powder. It is a soft material for foamed silicate building products, slag sound-absorbing bricks, insulation layers, and water-absorbing layers. Slag is formed by rapidly cooling molten blast furnace slag in water. There are two main methods: slag pool water quenching and furnace front water quenching. After grinding, slag can be used in cement plant concrete mixing stations. A slag mill production line can process solid waste and turn it into treasure.

 

Liming Heavy Industry is a professional manufacturer that provides slag mill production lines. It has rich experience and superb technology. The vertical mill is energy-saving and increases production. In addition, the process flow is scientific and the powder making efficiency is high. It is deeply favored by customers of solid waste residues such as slag, steel slag, fly ash, and coal gangue.

 

1. The advantages of water slag mill

 

In the field of industrial solid waste, vertical mill is a grinding machine developed by Liming Heavy Industry to help solid waste realize the recycling value. It integrates crushing, grinding, drying, grading, conveying and collecting. The equipment has the features of stable performance and simple process flow, small footprint, low noise, low dust, simpler maintenance and less consumption of wear-resistant materials. It is a powerful assistant for turning water slag into treasure.

 

(1) Low investment

The structure is compact and the footprint is small, which is 50% of the ball mill. It can be arranged outdoors and has low construction cost, which directly reduces the investment cost of the enterprise.

 

(2) Easy maintenance

Low wear, grinding roller and grinding disc lining are made of special materials and have a long service life. There is a large space for replacing roller sleeve lining and grinding mill maintenance.

 

(3) Reliable performance

The new grinding roller sealing device is adopted, which is reliable in sealing and does not require a sealing fan, further reducing the oxygen content in the mill and having excellent explosion suppression performance.

 

(4) High automation

Adopting PLC full-automatic control, remote control can be realized, and the operation is easier.

 

(5) High efficiency

High grinding efficiency, low energy consumption, and large single-machine production capacity.

 

(6) Good quality of finished products

The product particles are uniform in shape, narrow in particle size distribution, good in fluidity, strong in product adaptability, and high in whiteness and purity.

 

(7) Environmental protection

The system is fully sealed and operates under negative pressure, with less dust emission, energy saving and environmental protection.

 

2.The process flow of slag mill production line

 

The process flow of vertical mill mainly includes four steps: crushing, grinding, grading, and powder collection.

 

The raw ore is crushed by the crusher; in the grinding stage, the crushed material is crushed by extrusion, grinding and shearing under the pressure of the grinding roller. Hot air is ejected upwards evenly at high speed from the air ring surrounding the grinding disc. The ground material is blown up by the high-speed airflow at the air ring. On the one hand, the coarser material is blown back to the grinding disc for re-grinding, and on the other hand, the suspended material is dried. The fine powder is brought into the grading machine by the hot air for grading. The qualified fine powder is discharged from the mill along with the air flow and collected by the dust collection equipment as the product.

 

Liming Heavy Industry is based on the solid waste slag recycling channel and continuously supplies customers with water slag grinding mill production line solutions.
