Abstract
The utility model relates to a rotor type centrifugal crusher, which mainly comprises a crushing chamber with a built-in lining plate, a conical throat, a blast chamber, a crushing and grading wheel set, a blast wheel and other parts. It features small size, large treating capacity, saving electricity and uniform granularity, and may be widely used in superfine grinding of non-hard materials such as pigment, paint, chemical raw material and non-metal ore.
Description
The utility model is a kind of rotor type centrifugal pulverizer that is widely used in the ultra-fine grinding processing of non-hard materials such as pigment, coating, industrial chemicals, nonmetallic ore.
At present, be used for the equipment of material ultra-fine grinding processing, defective such as the ubiquity volume is big, power consumption is big, noise is big, treating capacity is little.The cam pulverizer that generally adopts with chemical industry is an example, and this pulverizer is mainly by drive disk assembly, and several parts such as high speed rotary body of taper pulverizing chamber, band ratchet are formed.Because the asymmetric layout of ratchet produces very big unbalance inertia force, causes serious vibration, parts damages such as bearing are frequent, and the milling product coarse size.
The purpose of this utility model provides a kind of rotor type centrifugal pulverizer, make non-hard material ultra-fine broken processing epigranular, power consumption is low, noise is little.
The technical solution of the utility model is: by comminuting matter in material inlet enters the first pulverizing chamber A, the blade of crushing wheel has 15 °～45 ° axial torsional angles, help to form axial flow rotation blast, the blade of crushing and classification wheel is radially arranged, so that formation swirling eddy, in the pulverizing chamber A with the material particles of air-flow rotation except that each other collision, impacting, also bump with counterpunch board, simultaneously because action of centrifugal force, material particles is thrown toward on the liner plate, be subjected to bump, punching once more, be ground into fine powder; If greater than axial suction, then being trapped in the pulverizing chamber A, the centrifugal force that material is subjected to continued to pulverize; The centrifugal force that is subjected to is less than axial suction, and then material enters in the second pulverizing chamber B with air-flow by the taper venturi, and material is subjected to once more impacting, collides and further pulverized.Material after the pulverizing enters in the blast chamber C with air-flow and is discharged from outside the machine.
Accompanying drawing is a structural representation of the present utility model, and its drawing label is:
1. motor 2. 3 is separated 6. blowdowns of belt 3. belt pulleys 4. bearing blocks 5. sealing devices and is chewed 7. blast wheels, 8. discharge material mouths, 9. taper venturis, 10. flat keys, 11. cylindrical shells, 12. power transmission shafts, 13. crushing wheel 13a. crushing and classifications and take turns 14. counterpunch boards, 15. liner plates, 16. material inlets, 17. blast pipes, 18. volume dampers, 19. frames
The utility model mainly is made up of four parts: (one) drive disk assembly; (2) cylindrical shell rack unit; (3) rotation crushing part; (4) blast wheel discharge parts.Be illustrated respectively below:
