How to choose the vertical mill mill for grinding slag in cement plant

Kategorie: Allgemein – crushermachine2 – 04:35

The slag has been treated as pollutants before the reform and opening up in China. With the development of the times, domestic cement manufacturers introduce advanced foreign cement technology, the cost of new cement is several layers lower than the cost of traditional cement production, and the quality of new cement. It is better than the traditional cement quality. As the cost of cement production goes down, the price of new cement is not sold in the market. The price of traditional cement is coming to an end. The end of a product era will always have the rise of another thing, the slag is no longer discarded as a pollutant, and the slag in the cement factory becomes a treasure. This is what people often say is a kind of column that turns waste into “treasure.”
The slag is the post-product of the precious metal refining in the factory. The slag is relatively hard. The slag purchased by the cement plant cannot be used directly. The slag must be ground into powder by the vertical roller mill. Because the slag is very hard, the equipment can hardly be ground. SBM heavy-duty introduction of Loesche vertical grinding technology and independent research and development, produced the equipment to treat slag “slag vertical grinding” is the working principle of slag vertical mill processing slag:
The raw slag of the slag vertical mill enters the feeding bin through the grab machine. After the metering, it is fed into the screw feeding device by the conveying belt and fed into the roller vertical mill. The material in the grinding rotates with the grinding disc under the centrifugal force from the center to the edge. After moving, after compaction, degassing and grinding process, the material is brought up by the hot air entering from the wind ring at the edge of the grinding disc, and is instantaneously dried. The finer particles are taken to the classifier for sorting, and the coarse powder is returned to the grinding disc. Grind again. The qualified fine powder is taken into the bag filter to separate the gas powder after the finished product is collected. After the finished product is collected, it is transported into the finished bulk warehouse, and the exhaust gas is discharged after being silenced by the fan. Partially difficult to grind large particle material (and iron tumor, iron slag)
