Slag micro-powder vertical roller mill for processing

Slag micro-powder vertical roller mill for processing nickel slag steel slag manganese ore slag

The slag micropowder product can be re-applied in the production of the mineral industry. For example, a smelter can recycle some metal materials after grinding for new metal smelting. Steel companies can also use some of the important material elements as auxiliary additives for steel production, etc., to meet the slag. Recycling in the industry. Most of the slag is recycled to the metal, and a large part of it is used in industrial production. These can be used as raw materials for cast stone, glass ceramics, fertilizer, enamel, ceramics, slag cement, slag concrete, and the like.

The slag micro-powder Vertical Roller Mill is currently used in the grinding of non-inflammable and explosive materials such as building materials, chemicals, metallurgy, paint, paper, rubber, medicine, food and other humidity below 6% and Mohs hardness below 7.

Suitable materials for slag vertical roller mill are: kaolin, barite, fluorite, talc, water slag, ash calcium powder, wollastonite, gypsum, limestone, phosphate rock, marble, potassium feldspar, quartz sand, bentonite, manganese ore, etc. Mohs grade 7 or less.

Structure and working principle of slag micro-powder vertical roller mill

The motor driven reducer drives the grinding disc to rotate, and the material to be ground is fed into the rotating grinding disc center by the lock air feeding device. Under the centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller. Under the action of the pressure of the grinding roller, the material is crushed by being pressed, ground and sheared. At the same time, the hot air is evenly sprayed upward from the wind ring surrounding the grinding disc, and the material after the grinding is blown by the high-speed airflow at the wind ring. On the one hand, the coarser material is blown back to the grinding disc for re-grinding, on the other hand, the suspension is suspended. The material is dried, and the fine powder is brought into the separator for classification. The qualified fine powder is ground with the airflow and collected by the dust collecting equipment, which is the product. The unqualified coarse powder falls again under the action of the separator blade. To the grinding disc, re-grind with the newly fed material, and so on, to complete the whole process of the grinding operation.

1. Advantages of slag micro-powder vertical roller mill

(1) High grinding efficiency and low energy consumption, compared with ball mills, energy consumption is 40%-50% lower;

(2) The capacity of single machine is large, and low valley electricity can be utilized;

(3) Vertical grinding technology and equipment is a new energy-saving and consumption-reducing technology advocated by China, which is conducive to enhancing the competitiveness of enterprises in the field of powder industry in the region and even in China;

2, easy maintenance, low operating costs

(1) The grinding roller can be turned out of the machine by hydraulic device, and the replacement of the roller lining plate and the grinding machine has large maintenance space, and the maintenance operation is very convenient;

(2) The roller sleeve can be turned over to extend the service life of the wear-resistant material;

(3) There is no need to fabric on the grinding disc before starting the machine, and the mill can be started at no load, eliminating the trouble of starting the machine;

(4) Low wear, the grinding roller and the disc liner are made of special materials and have a long service life;

(5) High degree of automation: The automatic control technology adopts the German Si series PLC, equipped with an automatic control system, which can realize remote control, easy operation, and the workshop can basically realize unmanned operation and save operating costs.

3. Environmental protection

(1) The whole system has small vibration and low noise;

(2) The whole system is sealed, fully negative pressure running, no dust overflow, basically can achieve dust-free workshop;
