Description

Technical Field

[0001] The utility model relates to the technical field of ore crushing, in particular to a crusher for ore dressing. Background Art

[0002] Cage crusher is a medium-sized horizontal cage bar crusher. It is designed based on the principle of impact crushing. The inner and outer sets of cage bars rotate towards each other at high speed, and the material is crushed from the inside to the outside by the impact of the cage bars.

[0003] There are two processes for applying kaolin in industrial production: dry process and wet process. The dry process is a simple and economical processing technology. The mined ore is crushed to 25.4mm by a hammer mill and then fed into a cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture content of the kaolin from 20% to about 10%. The crushed ore is further ground by an air-blown Raymond mill equipped with a centrifugal separator and a cyclone dust collector. The entire grinding process is time-consuming and labor-intensive, and is very likely to generate smoke and dust, affecting the health of workers. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See Figures 1 to 4 In the embodiment of the present utility model, a crusher for mineral processing includes a base 1, a crushing barrel 3, a discharge barrel 4, a shearing and crushing assembly, an extrusion and crushing assembly, a grinding assembly and a rotary drive assembly; the base 1 is fixedly connected to a support frame 2, the crushing barrel 3 is fixedly connected to the support frame 2, the discharge barrel 4 is fixedly connected to the top of the crushing barrel 3, the crushing barrel 3 is fixedly connected to a mounting frame 5, the mounting frame 5 is rotatably connected to a rotating shaft 6, the bottom of the crushing barrel 3 is fixedly connected to a discharge barrel 12, the discharge barrel 12 is fixedly connected to a guide plate 13, and a discharge port 14 is provided in the guide plate 13; the shearing and crushing assembly is installed in the discharge barrel 4 for shearing and dividing the large pieces of ore in the discharge barrel 4; the extrusion and crushing assembly is installed on the rotating shaft 6 On, it is used to extrude and crush the small pieces of ore after segmentation; the grinding assembly is installed on the rotating shaft 6, and is arranged below the extrusion and crushing assembly, and is used to grind the ore after extrusion and crushing; the rotary drive assembly is installed between the base 1 and the rotating shaft 6, and is used to drive the rotating shaft 6 to rotate. The utility model first holds the large pieces of ore through the discharge barrel 4, and then drives the rotating shaft 6 to rotate through the rotary drive assembly, and the rotating shaft 6 drives the extrusion and crushing assembly and the grinding assembly to rotate. At this time, the ore is first sheared and crushed by the shearing and crushing assembly, and then the ore is extruded and crushed by the extrusion and crushing assembly and conveyed to the grinding assembly. Finally, the ore is ground by the grinding assembly, and the ground ore is discharged in the discharge barrel 12.

[0025] In one embodiment of the present invention, see Figures 1 to 4The shearing and crushing assembly includes a first turntable 15 fixedly connected to the top of the rotating shaft 6, and a first shearing groove 16 is provided in the first turntable 15. A fixed seat 17 is fixedly connected to the discharge barrel 4, and a first motor 18 is fixedly connected to the fixed seat 17. A second rotating disk is fixedly connected to the output shaft of the first motor 18, and a second shearing groove 20 is provided in the second rotating disk. The first shearing groove 16 and the second shearing groove 20 cooperate with each other. The shearing and crushing assembly drives the second rotating disk to rotate through the first motor 18, and at the same time drives the second rotating disk to rotate through the rotating shaft 6, and the rotation directions of the first rotating disk and the second rotating disk are opposite. At this time, the first shearing groove 16 and the second shearing groove 20 are staggered and sheared with each other, thereby shearing and crushing the ore falling into the first shearing groove 16 and the second shearing groove 20.

[0026] In one embodiment of this invention, see Figures 1 to 4 The extrusion and crushing assembly includes a conical barrel 7 fixedly connected to the rotating shaft 6, and a spiral extrusion groove 8 is fixedly connected to the outer wall of the conical barrel 7.

At this time, the extrusion and crushing assembly first rotates and introduces the small pieces of ore sheared and crushed by the shearing and crushing assembly through the top of the spiral extrusion groove 8, and due to the setting of the conical barrel 7, the diameter of the spiral extrusion groove 8 gradually decreases from top to bottom. As the ore is gradually conveyed to the grinding assembly, the ores are gradually squeezed against each other, and the closer to the bottom of the conical barrel 7, the greater the extrusion force between the ores, and finally the extrusion crushing of the ore is achieved.

[0027] In one embodiment of this invention, see Figures 1 to 4 The grinding assembly includes a grinding cylinder 9 fixedly connected to the rotating body, and a plurality of groups of circumferentially distributed grinding grooves 10 are provided in the grinding cylinder 9.

The grinding teeth 11 cooperate with the grinding grooves 10. First, the ore crushed by the extrusion crushing assembly falls into the grinding groove 10, and with the rotation of the grinding cylinder 9, the ore and the inner wall of the crushing barrel 3 are driven to rotate relative to each other. At this time, the ore in the grinding groove 10 fits with the grinding teeth 11, and the ore is ground by the mutual friction between the ore and the grinding teeth 11. In addition, the grinding groove 10 gradually shrinks from top to bottom, so that the ore and the grinding teeth 11 fit closely.

[0028] In one embodiment of this invention, see Figures 1 to 4The rotation drive assembly includes a first pulley 21 fixedly connected to the rotating shaft 6, a second motor 22 fixedly connected to the base 1, a second pulley 23 fixedly connected to the output shaft of the second motor 22, and a transmission belt 24 is connected between the first pulley 21 and the second pulley 23. The rotation drive assembly drives the second pulley 23 through the second motor 22, and the second pulley 23 drives the first pulley 21 to rotate through the transmission belt 24, and the first pulley 21 drives the rotating shaft 6 to rotate.
