Slag vertical mill is an ideal large-scale grinding equipment, belonging to a kind of roller grinding, widely used in cement, electric power, metallurgy, chemical industry, non-metal mining and other industries.stries.It integrates crushing, drying, grinding, grading and conveying. It has high production efficiency and can grind bulk, granular and powdery raw materials into the required powdery form.What about Liming Heavy Industry’s slag vertical Mill?What are the advantages?
Application scope of slag vertical mill:
Slag vertical mill is an ideal large-scale grinding equipment, which is widely used in sand and gravel yards, concrete mixing stations, dry mortar, power plant desulfurization, quartz sand and other industries.It integrates crushing, drying, grinding, grading and transportation, and has high production efficiency. It can grind river pebbles, granite, basalt, quartz, iron ore, diabase, limestone, calcite, dolomite, barite, talc, gypsum, bentonite and other raw materials into the required powdery materials.
the characteristics of slag vertical grinding:
1. Production investment costs have been significantly reduced .Because the vertical mill system is simple and compact in layout, it covers an area of only 50% of the ball mill system, and can be arranged in the open air, which directly reduces the investment cost of the enterprise.
2. High production efficiency, energy saving and environmental protection .The energy consumption of the vertical mill system is 30% to 40% lower than that of the ball mill system; the entire system has low vibration, low noise, and the equipment is sealed as a whole. The system works under negative pressure, no dust spills, and the environment is clean, which meets the national environmental protection requirements.The working mechanism is changed, the wear is reduced, and the life of the machine is extended.
3. Strong material drying ability
4. Easy to operate and easy to maintain .Equipped with an automatic control system, remote control can be realized and the operation is easy; by overhauling the oil cylinder and flipping the boom, the roller sleeve and liner can be easily and quickly replaced, reducing the loss of enterprise downtime.
5. Product quality is stable .The material has a short residence time in the body, which is easy to detect and control the particle size and chemical composition of the product, reduce repeated milling, and stabilize product quality.
Third, the working principle of slag vertical mill:
1. The raw material enters the cutting pipe through the rotary feeder, and the cutting pipe enters the inside of the mill through the side or middle of the separator.
2. The material falls to the center of the grinding disc by means of the impact of gravity and airflow.The grinding disc is firmly connected to the reducer and rotates at a constant speed.The constant-speed rotation of the grinding disc evenly distributes the grinding material horizontally on the liner of the grinding disc, where the oblique cone grinding roller bites the material and crushes it.Under the action of the hydraulic system, the material is ground due to pressure and friction.
3. Centrifugal force throws the crushed material from the middle of the grinding disc to the edge of the grinding disc. The material leaving the grinding disc encounters the hot gas entering the mill through the air ring, and rises accordingly. It enters the separator through the middle shell of the mill. In this process, the material and the hot gas have sufficient heat exchange, and the water is quickly evaporated, so that the remaining water reaches 1%.The materials that have not been crushed to the specified requirements are selected by the separator.And is sent back to the grinding disc for re-grinding.The material that passes through the separator is carried by the air flow generated by the mill fan and enters the dust collector.
