Abstract
The utility model relates to an outer circulation vertical mill system. The outer circulation vertical mill system comprises a vertical mill and a dynamic powder concentrator, wherein a feeding hole of a first elevator is formed at a discharge hole of the vertical mill, a discharge hole of the first elevator is formed at a feeding hole of the dynamic powder concentrator, a feeding hole of a second elevator is formed at a coarse powder discharge hole of the dynamic powder concentrator, and a discharge hole of the second elevator is formed at a feeding hole of the vertical mill.
Description
Technical field
The utility model relates to a kind of vertical mill system, particularly a kind of outer circulation vertical mill system.
Background technology
Current, domestic Vertical Mill of milling for granular material, what generally adopt is the Vertical Mill internal circulation system that carries powder concentrator, namely by hot blast in the mill, with material at the mill internal classification.This just requires bigger blast and wind speed that the material web on the mill is gone into powder concentrator.The pressure loss of Vertical Mill internal circulation system circulated air is big, quick abrasions such as grinding roller, mill, and the installed power height, volume is big, the energy consumption height.
The utility model content
In order to solve problems of the prior art, the purpose of this utility model provides a kind of energy-conservation, the outer circulation vertical mill system that production efficiency is higher, volume is little.
To achieve these goals, the utility model is taked following technical scheme: a kind of outer circulation vertical mill system, comprise Vertical Mill and dynamic powder concentrator, described Vertical Mill the discharging opening place be provided with the charging aperture of first elevator, the discharging opening of described first elevator is located at the charging aperture place of dynamic powder concentrator, the meal discharging opening place of described dynamic powder concentrator is provided with the charging aperture of second elevator, and the discharging opening of described second elevator is located at the charging aperture place of Vertical Mill.
Adopt technique scheme, the utlity model has following beneficial effect: the utility model adopts the external mode of powder concentrator, material by Vertical Mill mill finish after, all discharge outside the mill, to go out grind materials by elevator and send into external dynamic powder concentrator and carry out gradation, meal returns and continues in the mill to mill.Compare with the Vertical Mill internal circulation system, the difference of the utility model maximum is to have cancelled circulating air system in the mill, has reduced system energy consumption.
Description of drawings
Fig. 1 is the structural representation of a kind of outer circulation vertical mill system of the utility model.
Among the figure: 1, Vertical Mill; 2, first elevator; 3, dynamic powder concentrator; 4, second elevator.
The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
As shown in Figure 1, a kind of outer circulation vertical mill system, comprise Vertical Mill 1 and dynamic powder concentrator 3, described Vertical Mill 1 the discharging opening place be provided with the charging aperture of first elevator 2, the discharging opening of described first elevator 2 is located at the charging aperture place of dynamic powder concentrator 3, the meal discharging opening place of described dynamic powder concentrator 3 is provided with the charging aperture of second elevator 4, and the discharging opening of described second elevator 4 is located at the charging aperture place of Vertical Mill 1.
The material of milling through Vertical Mill 1 is sent into it in dynamic powder concentrator 3 with first elevator 2, carries out the classification processing, and fine powder is selected to be walked, and meal is sent into Vertical Mill 1 by second elevator 4 and milled again.
In the said process, the material thickness grating after Vertical Mill 1 is milled is reasonable, and the classification that more is conducive to dynamic powder concentrator 3 is handled.Vertical Mill 1 external circulating system is not because no circulated air in the mill has air loss, and grinding roller, abrasive disk abrasion are relatively slow, and installed power, volume are less relatively, and system energy consumption is relatively low.
Claims (1)
1. outer circulation vertical mill system, comprise Vertical Mill and dynamic powder concentrator, it is characterized in that described Vertical Mill the discharging opening place be provided with the charging aperture of first elevator, the discharging opening of described first elevator is located at the charging aperture place of dynamic powder concentrator, the meal discharging opening place of described dynamic powder concentrator is provided with the charging aperture of second elevator, and the discharging opening of described second elevator is located at the charging aperture place of Vertical Mill.
