Description
Auto-circling ultra-fine crusher relates to a kind of solid material ultra-fine grinding equipment.
In the solid material comminution process, the energy of input has only small part to be converted into the useful work of material comminution, most of with heat energy, acoustic energy, forms such as wearing and tearing energy consume, so, the energy consumption of research comminution operation, improving the capacity usage ratio of comminution process, is the mineral processing industry, energy-conservation valid approach such as building materials industry.Present comminution process, the capacity usage ratio of muck are far above ore grinding, and how broken few mill, reduction mill feed material size are the extensive power-economizing methods that adopts.Yet, most equipment in small, broken bits is because of gape and operating pressure adjusting difficulty, there are very big contradiction in ore discharge granularity and output, can only under thicker granularity, just enter the grinding operation of next stage, cause the energy consumption of material comminution, steel consumption is all very high, as the ore dressing plant, final garrulous ore granularity has only about 20mm, and the principle of how broken few mill can not get well implementing.
Known spallar is of a great variety, as the gyratory crusher that coarse crushing is used, jaw crushing; Circular cone spallar in small, broken bits in the work, the reaction type spallar, vertical impact crusher is made ultra-fine broken centrifugal unit for inertial conic spallar, and kibbler rolls etc. in different industries, find broad application.Yet these equipment are limit because of principle or structure, and product granularity is still thin inadequately, and energy-saving effect is not really remarkable, therefore, studies ultra-fine grinding equipment efficiently, is the heat subject of comminution area research.
Impact breaker, impact crusher, the ore discharge granularity can be controlled carefullyyer, but during its breaking ores, counterpunch board and impact head hit ore with high speed, and when ore hardness was big, serious wearing and tearing caused counterpunch board frequent with the replacing of impacting head, equipment operation rate descends, production capacity is not high, makes troubles to operation, so, for the big metallic ore of hardness, the few employing.
Unit for inertial conic crusher on the basis of general gyratory crusher, adds centrifugal intertia force, and mantle is improved greatly to the impulsive force of ore, and product granularity can reduce.But the ore discharge granularity of this equipment is to lean on the size of gape to determine, when the ore discharge granularity was thin, (as 2～3mm), this moment, gape stopped up into insoluble problem to require very little gape size.
High-pressure roller mill adopts bed of material shattering to design, and capacity usage ratio is greatly improved, and is one of main direction of research at present.This equipment, material pressurized and broken between two high pressure roller when requiring thinner ore discharge product, need impose very high pressure, has brought device fabrication precision height thus, and installation power height, equipment are very expensive.For the higher metallic ore of hardness, required pressure is higher, owing to make, operating difficulties is not almost used at metal mine.
The purpose of this utility model is to adopt bed of material shattering, middle pressure crushing force, and self-loopa is crumbling method repeatedly, is implemented under the lower pressure, to the ultra-fine grinding of harder ore.The capacity usage ratio height of muck not only, product granularity is superfine, and device structure is able to tubeization because of not needing too high pressure, and operating technology is less demanding, realizes comprising the ultra-fine grinding of the solid material of hard ore.
Technology contents of the present utility model is: this machine is formed structure by large cylinder 1, little cylindrical shell 2, little cylinder bearing device 3, large cylinder supporting arrangement 4, large cylinder transmission mechanism 5, little cylindrical shell transmission mechanism 6, give ore deposit chute 7, ore discharge device 8 eight parts are formed, and large cylinder 1 is supported on the large cylinder supporting arrangement 4 by rolling ring, connect with gear 15 with gear ring 10, link by power transmission shaft and motor, little cylindrical shell 2 is that a semi-cone angle is the taper type cylindrical shell of β, is positioned at large cylinder 1 again, little cylinder bearing device 3 by two ends supports, and links by decelerator 17 and motor 16.Large cylinder 1 inwall and little cylindrical shell 2 outer walls minimum together can be regulated by the increase and decrease of pad 18 with crack B.
Large cylinder supporting arrangement 4 is by support 20, bearing 21, and roller bearing 22 3 parts are formed, and roller bearing 22 is fixed in by bearing 21 among the support 20, rotates freely around self axis.All roller bearings 22 are mutually external with the rolling ring of large cylinder 1.
Little cylinder bearing device 3 is by bearing 23, pad 18, and bearing block 24, compression spring 19 4 parts are formed, and bearing block 24 is loaded in the slideway of bearing 23 inside, presses the flexible of knot spring 19 regulating by screw rod.
This machine operation principle:
Large cylinder 1 is under the drive of large cylinder transmission mechanism 5, and little cylindrical shell 2 rotates with identical direction under the drive of little cylindrical shell transmission system 6.The coarse solids material feeds between large cylinder 1 and the little cylindrical shell 2 uniformly by giving ore deposit chute 7, and the large cylinder 1 and the little cylindrical shell 2 that are rotated are brought fracture area into, are extruded simultaneously, shear and fragmentation.Material after being broken returns fracture area with the inwall rotation of large cylinder 1, is subjected to fragmentation for the second time, and breakdown products is returned and is subjected to fragmentation for the third time again with the rotation of large cylinder 1 inwall, so goes on, and material obtains self-loopa fragmentation repeatedly.When the material guide plate of ore discharge device 8 makes material rotate with large cylinder 1 inwall, move to mine-discharging terminal, material whenever is broken once, just moves a segment distance to mine-discharging terminal, and material is through repeatedly broken, and discharging from mine-discharging terminal at last becomes qualified particulate product.
The utility model compared with prior art has the following advantages:
1, adopt bed of material shattering to design, the capacity usage ratio height, the steel consumption is low.
Material is broken in the process, can be by regulating the thickness of the clearance control material between large cylinder and the little cylindrical shell, and realize that the bed of material pulverizes, thereby the capacity usage ratio of fragmentation is improved greatly.The contact velocity of material and equipment is not high, and it is little to wear and tear, and the steel consumption is low.
2, realized the material self-loopa, middle press-powder is broken, greatly reduces the manufacturing expense and the installation power of equipment.
3, product granularity is adjustable on a large scale, and it is heavy that material contains moisture, when the ore discharge granularity is very thin, do not have the equipment clogging.
4, realized " how broken few mill " principle, control well and can replace kibbling mill, reach " only brokenly do not grind " purpose, have considerable energy saving consumption reduction effect.
