Fig. 2 is the structural representation of vertical roller grinder system of the prior art.
In figure: 1, ingredient sector; 2, vertical roller grinder device; 3, secondary powder concentrator; 4, dust-precipitator; 5, blower fan; 6, three grades of powder concentrators.
The specific embodiment
For further understanding innovation and creation content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1, a kind of vertical roller grinder system of preparing super fine, comprise ingredient sector 1, vertical roller grinder device 2, dust-precipitator 4 and blower fan 5, vertical roller grinder device comprises powder concentrator one time, the downstream of ingredient sector is connected with vertical roller grinder device, the air inlet UNICOM of the air outlet of dust-precipitator and blower fan, the air inlet UNICOM of the air outlet of blower fan and vertical roller grinder system, between vertical roller grinder device and dust-precipitator, be provided with the two-stage dynamic powder concentrator 3 and three grades of dynamic powder concentrators 6, the discharging opening UNICOM of the charging aperture of the two-stage dynamic powder concentrator and vertical roller grinder device, the coarse fodder discharging opening of the two-stage dynamic powder concentrator and the charging aperture UNICOM of vertical roller grinder device, the fines discharging opening of the two-stage dynamic powder concentrator and the charging aperture UNICOM of three grades of dynamic powder concentrators, the coarse fodder discharging opening of three grades of dynamic powder concentrators and the charging aperture UNICOM of vertical roller grinder device, the fines discharging opening of three grades of dynamic powder concentrators and the entrance UNICOM of dust-precipitator.
The operation principle of this patent is:
New material and outer circulation material that ingredient sector coordinates feed grinding machine jointly, in vertical roller grinder device, pulverized, the one-level powder concentrator that material after pulverizing carries through vertical roller grinder device carries out a sorting, coarse fodder continues grinding, and fines is brought into secondary powder concentrator as semi-finished product by gas and carried out secondary sorting.
Secondary sorting completes in the two-stage dynamic powder concentrator, meal returns to feeding belt 7 by the coarse fodder discharging opening of secondary powder concentrator lower end through material return system, enter vertical roller grinder device grinding again, fines is brought into three grades of powder concentrators as semi-finished product by gas and is carried out three sortings.
Be sorted on for three times in three grades of dynamic powder concentrators and complete, meal returns to feeding belt by the coarse fodder discharging opening of three grades of powder concentrator lower ends through material return system, enters grinding machine grinding again, and qualified fine powder is sent into by bag filter and collected.
