Vertical roll grinder integrates fragmentation, grinding, homogenizing, oven dry, classification and conveying function.Because the grinding mechanism of vertical roll grinder is simple, easy to operate, to the advantage such as low that requires of material, vertical roll grinder is widely used in recent years; , because vertical roll grinder is to utilize material bed principle to carry out grinding, avoid intermetallic shock and wearing and tearing, galling amount is little, contamination of products is little; Because it is that wind is swept formula grinding, with the micro-powder graded function in inside, micro powder product fineness regulation is simple, has avoided crossing grinding phenomenon, has reduced the consumption of idle work, and mill efficiency is high; Because the outer circulation of material in mill can reduce the required blower fan load of airlift material in mill effectively, be conducive to reduce SR and power consumption again.
How hierarchy and vertical roll grinder reasonable in design is used in combination, reach the maximization of vertical roll grinder, and even running, energy grinding goes out the micro powder product of high fineness, the timely and effective adjusting control micro powder product fineness of energy, improves working (machining) efficiency and also ensures that the quality of production is current problem demanding prompt solution.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of vertical many rotors super fine grader, can accomplish the maximization of vertical roll grinder, and even running, energy grinding goes out the micro powder product of high fineness, the timely and effective adjusting control micro powder product fineness of energy, and there is the classifying capability matching with grinding machine milling capacity.
The technical solution of the utility model is as follows:
Vertical many rotors super fine grader, comprise the housing that is installed on roller mill mill upper end, it is characterized in that: in described housing, be provided with arc-shaped partition, housing is divided into multiple independently chambers by arc-shaped partition, in each chamber, be equipped with vertical single rotor sound state combination formula efficient classification device, the top cover center of described housing is provided with the total discharging air port being connected with the discharging air port of each vertical single rotor sound state combination formula efficient classification device, the lid periphery of housing is provided with and vertical single rotor sound state combination formula efficient classification device charging chute one to one, the ash bucket lower end of described vertical single rotor sound state combination formula efficient classification device is connected with the feeding chute towards mill central authorities.
Described vertical many rotors super fine grader, include housing, it is characterized in that: described vertical single rotor sound state combination formula efficient classification device comprises cylindrical shell, cage-type rotor is installed in cylindrical shell, cage-type rotor has the motor that is installed on housing upper end to drive, cage-type rotor periphery is provided with wind blade, and the lower end of wind blade is provided with the ash bucket of taper, and ash bucket lower end is provided with the feeding chute towards mill central authorities.
The utility model has the advantages that:
The utility model is novel, structure is ingenious, processing and fabricating is installed simply, sealing is more safe and reliable, can realize product fineness 1250 orders 97% passes through, also have that single machine yield is higher, classification efficiency is high, the advantages such as adjusting leeway is large, can be widely used in the industries such as non-ore deposit, cement, electric power, chemical industry, pottery.
brief description of the drawings:
Fig. 1 is top view of the present utility model.
Fig. 2 is front view of the present utility model.
detailed description of the invention:
Referring to accompanying drawing:
Vertical many rotors super fine grader, comprise the housing 1 that is installed on roller mill mill 9 upper ends, in housing 1, be provided with arc-shaped partition 2, housing 1 is divided into multiple independently chambers 3 by arc-shaped partition 2, in chamber 3, it is territory, powder-separating area, do not interfere with each other, in each chamber 3, be equipped with vertical single rotor sound state combination formula efficient classification device 4, the top cover center of housing 1 is provided with the total discharging air port 6 being connected with the discharging air port 5 of each vertical single rotor sound state combination formula efficient classification device 4, the top of housing 1 is provided with charging chute 7, its port of export is towards the central authorities of mill 9, ash bucket 8 lower ends of vertical single rotor sound state combination formula efficient classification device 4 are connected with towards the feeding chute 10 of mill 9 central authorities and export.
Vertical single rotor sound state combination formula efficient classification device 4 comprises cylindrical shell 11, cage-type rotor 12 is installed in cylindrical shell 11, cage-type rotor 12 is driven by the motor 13 that is installed on housing upper end, cage-type rotor 12 peripheries are provided with wind blade 14, the lower end of wind blade 14 is provided with the ash bucket 8 of taper, and ash bucket 8 lower ends are provided with the feeding chute 10 towards mill 9 central authorities.
The utility model operation principle: entering independently chamber 3 from bottom through the material of grinding together with air-flow is territory, powder-separating area, wind blade 14 makes dust, air form a slipstream, and motor 13 drives cage-type rotor 12 by carrying out High Rotation Speed with slipstream equidirectional.Gap location between wind blade 14 and cage-type rotor 12, has formed the space of a centrifugal force, and dust, air are separated.Oarse-grained material is thrown to the decanting zone of wind blade 14, because gravity falls, has left after gap location, is collected and returns grinding machine and carry out grinding again; Together with subparticle is mixed in air, go out mill by total discharging air port 6, by follow-up equipment---dust-precipitator is collected.The fineness of micro mist depends on the adjusting of cage-type rotor 12 rotary speeies.The rotating speed that improves rotor, the fineness of material is thinner; Otherwise, the rotating speed of reduction rotor, the particle of material will chap.
