Abstract
The utility model discloses a grinding roller bearing housing-free and non-bearing maintenance-free grinding mill. The grinding mill comprises a rack, wherein a main motor and a transmission assembly are assembled on the rack, a cover barrel with a feeding opening is also assembled on the rack, the upper part of the transmission assembly is positioned in the cover barrel, a classification mechanism is assembled on the upper part of the cover barrel, an air channel is formed on the lower part of the cover barrel, a grinding ring is arranged on the internal surface of the air channel, at least two supports are assembled on the transmission assembly, a transmission arm is hinged on each support through a rotating shaft, the other end of each transmission arm is hinged with a grinding roller device through another rotating shaft, a shovel blade is assembled on each transmission arm, and an air intake volute is further assembled on the rack and communicated with the air channel. The grinding mill is not provided with a grinding roller bearing housing and a star rack which are commonly used by an existing grinding mill, so that the grinding mill structure is simplified; in addition, less parts are easily damaged, so that the grinding mill has small maintenance difficulty, a long maintenance period and a long service life; and moreover, the grinding mill consumes small power and has high grinding efficiency.
Description
Technical field
The utility model belongs to ore grinding equipment, especially relates to a kind of without the grinding roller bearing chamber, without bearing freedom from repairs flour mill.
Background technology
The deficiency that existing roller mill such as centrifugal mill, Raymond mill, ultra-fine grinding mill, pressurization mill etc. grinding machine exists is mainly manifested in: one, and whole consumable accessory is many, and maintenance difficulty is large, and service life is short; Its two, the lower swing overhang roll mill adopts the compositions such as plum blossom frame, messenger bearing chamber, easily causes the distortion of plum blossom frame in the work, bearing chamber oil starvation, shaft of grinding roller split, the sealing of roll shaft chamber is bad, the grinding roller assembly takes out, the difficulty of packing into, maintenance cycle is short.
Summary of the invention
The purpose of this utility model provides that a kind of easy-maintaining, maintenance cycle are long, long service life new flour miller.
For achieving the above object, the utility model is taked following technical proposals: a kind of without the grinding roller bearing chamber, without bearing freedom from repairs flour mill, comprise frame, main motor and drive assembly are housed on the frame, cover cylinder with charging aperture also is housed on the frame, the top of drive assembly is positioned at the cover cylinder, classification mechanism is equipped with on the top of cover cylinder, the air channel is arranged at the bottom of cover cylinder, be provided with bull ring on the inner surface of air channel, at least two bearings are housed on the drive assembly, by the hinged transmission arm of rotating shaft, the other end of this transmission arm is hinged by other rotating shaft and a Burnisher apparatus, at each transmission arm a perching knife is housed on each bearing, the air intake spiral case also is housed on the frame, and the air intake spiral case communicates with the air channel.
The profile of the grinding roller of described Burnisher apparatus is cylindrical.
The profile of the grinding roller of described Burnisher apparatus is cydariform or taper.
Described bearing is three.
Adopt the flour mill of technique scheme, Burnisher apparatus is hinged by rotating shaft and transmission arm, transmission arm is hinged by rotating shaft and bearing, has saved existing grinding machine grinding roller bearing chamber and plum blossom frame commonly used, has simplified mill structure, and few easy workout part, so maintenance difficulty is little, maintenance cycle is long, long service life, and power consumption is little, and abrasive dust efficient is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is drive assembly and Burnisher apparatus connected mode schematic diagram.
The specific embodiment
Such as Fig. 1, shown in Figure 2 without the grinding roller bearing chamber, without bearing freedom from repairs flour mill, comprise frame 1, main motor and drive assembly 6 are housed on the frame 1, cover cylinder 7 with charging aperture also is housed on the frame, the top of drive assembly is positioned at the cover cylinder, classification mechanism 8 is equipped with on the top of cover cylinder, air channel 3 is arranged at the bottom of cover cylinder, be provided with bull ring 4 on the inner surface of air channel, at least two bearings 11 be housed on the drive assembly, on each bearing 11 by the hinged transmission arm 9 of rotating shaft, the other end of this transmission arm 9 is hinged by other rotating shaft and a Burnisher apparatus 5, at each transmission arm a perching knife 10 is housed, air intake spiral case 2 also is housed on the frame, air intake spiral case 2 communicates with air channel 3.
Bearing on the drive assembly is generally three, also can be two, perhaps four, five.
The profile of the grinding roller of Burnisher apparatus can for cylindrical, also can be cydariform or taper.Because grinding roller and bull ring are relation movingly, then the inner surface configuration of bull ring should be complementary with the profile of grinding roller.
The utility model in use, material is sent into from charging aperture, main motor drives drive assembly and then drives the Burnisher apparatus motion, material is pulverized between grinding roller and bull ring, the material that reaches fineness requirement is sent from the classification mechanism on top.Owing to having saved existing grinding machine grinding roller bearing chamber and plum blossom frame commonly used, simplified mill structure, and few easy workout part, so maintenance difficulty is little, maintenance cycle is long, long service life, and power consumption is little, and abrasive dust efficient is high.
Claims (4)
1. one kind without the grinding roller bearing chamber, without bearing freedom from repairs flour mill, comprise frame, main motor and drive assembly are housed on the frame, cover cylinder with charging aperture also is housed on the frame, the top of drive assembly is positioned at the cover cylinder, it is characterized in that: classification mechanism is equipped with on the top of cover cylinder, the air channel is arranged at the bottom of cover cylinder, be provided with bull ring on the inner surface of air channel, at least two bearings be housed on the drive assembly, on each bearing by the hinged transmission arm of rotating shaft, the other end of this transmission arm is hinged by other rotating shaft and a Burnisher apparatus, at each transmission arm a perching knife is housed, the air intake spiral case also is housed on the frame, the air intake spiral case communicates with the air channel.
