Specific embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
Embodiment: as shown in Figure 1, a kind of variable diameter ball mill, including the roller 10 for loaded material, the one of the roller
End is feeding end 11, and the other end is discharge end 14, and the feeding end is equipped with feeding inlet 12 and pan feeding end cover 13, the discharging
End is equipped with discharge port 15 and discharging end cover 16, is equipped with partition panel 17, the roller 10,17 and of partition panel in the roller 10
Pan feeding end cover 13 surrounds the first warehouse 20, and the roller 10, partition panel 17 and discharging end cover 16 surround the second warehouse
30, the inner wall of second warehouse is fixedly connected with the side of the second warehouse bracket 32, and the second warehouse bracket other side is fixed to be connected
Connect the second warehouse liner plate 31.The roller 10 be equipped with manhole 19 be used for carried out in cylinder maintenance or inspection section in operating condition.
Pan feeding end cover 13, discharging end cover 16, the first warehouse liner plate 21 and the second warehouse bracket 32 in the utility model is logical
It crosses screw to be fixed on roller 10, when ball mill works, without relative motion between each component, it is that roller 10 is divided by partition panel 17
One warehouse 20 and the second warehouse 30, the first warehouse inner wall fix the first warehouse of circle liner plate 21, and the second warehouse inner wall fixes a circle
Second warehouse bracket 32, the second warehouse stent outer fix the second warehouse of circle liner plate 31, and the second warehouse bracket is to the second warehouse
Liner plate is played a supporting role, although the internal diameter of roller is identical, due to being equipped with the second warehouse bracket, the second storehouse is indoor to be had
Diameter is imitated less than the indoor effective diameter in the first storehouse, according to the revolving speed calculating formula n=32/ (√ D) that ball mill classical theory is suitable for,
Wherein n is revolving speed, and √ D is radical sign D, and D indicates diameter, and the second warehouse should be selected due to the reduction of diameter according to traditional counting formula
High revolving speed, but it is practical since the first warehouse and the second warehouse are a roller, so selecting the first warehouse with traditional counting formula
In the case where revolving speed, actually reduce the revolving speed of the second warehouse, thus meet the first warehouse be crushing bin need high revolving speed,
Abrasive body hoisting depth is high, and the second warehouse is the requirement that pulverizing bin needs the slow-speed of revolution, abrasive body hoisting depth low, therefore this is practical
The novel cracking cabin enabled in ball mill and pulverizing bin while coordinating to carry out, achievees the purpose that saving the energy improves yield.
Wherein, the inner wall of first warehouse 20 is fixedly connected with the first warehouse liner plate 21.First warehouse liner plate and the second storehouse
Room liner plate also generates certain influence other than protecting roller tube to the characteristics of motion of abrasive body.The roller 10 is cylinder
Cylinder, the effective diameter of first warehouse are the cylinder diameter that the first warehouse liner plate 21 surrounds, and second warehouse has
Effect diameter is the cylinder diameter that the second warehouse liner plate 31 surrounds, effective diameter the having less than the first warehouse of second warehouse
Diameter is imitated, preferably, the effective diameter of second warehouse is 0.6-0.9 times of the first warehouse effective diameter, i.e., described first
Warehouse 20 is cracking cabin, and second warehouse 30 is pulverizing bin, and the partial size for being crushed warehouse discharging is greater than the partial size of grinding warehouse discharging.Institute
It states and is additionally provided with circular platform type outlet 40 on the outside of discharging end cover, the outlet stub end is fixedly connected with discharge end 14.
The material for meeting fineness requirement after the second warehouse grinding enters circle by the discharge port on discharge grid plate, discharging end cover
It is discharged after bench-type outlet.The partition panel 17 is distributed material of several first discharge holes for cracking cabin and discharges to pulverizing bin.
The discharge end is additionally provided with discharge grid plate 18, which is set to the inside of discharging end cover, and has one between the two
Fixed gap, the discharge grid plate 18 are equipped with several second discharge holes.
The operating process of the utility model: arrow shows the direction of charging and discharging in Fig. 1, and the material to grinding is led to
It crosses feeding inlet 12 and is sent into the first warehouse 20 (cracking cabin), motor drives roller 10 to rotate so that material is crushed, broken
Material enters the second warehouse 30 (pulverizing bin) by the first discharge hole on partition panel 17 and carries out grinding, because pulverizing bin is effective
Internal diameter is less than the effective diameter of cracking cabin, therefore the hoisting depth of pulverizing bin abrasive body is low and revolving speed is low, therefore material is in grinding
The grinding effect in storehouse increases, and impact effect reduces；The material for being ground to suitable mesh number through pulverizing bin passes through discharge grid plate 18, discharging
Discharge port 15 on end cover is discharged after entering circular platform type outlet 40.The utility model uses isodiametric roller cylinder
Body reduces effective internal diameter of pulverizing bin and increasing bracket in pulverizing bin, that is, changes the internal diameter in each storehouse in roller, from
And meet that crushing bin needs high revolving speed and abrasive body hoisting depth is high, pulverizing bin needs the slow-speed of revolution and abrasive body hoisting depth is low
Requirement, not only ensure that cracking cabin broken dynamics and effect, but also improve the grinding effect of pulverizing bin, had very strong practical
Property.
It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the premise utility,
Various modifications and improvements can be made, and these are all within the protection scope of the present invention.Therefore, the utility model patent
The scope of protection shall be subject to the appended claims.
