Description
Technical field
The utility model relates to fine crusher technical field, particularly relates to a kind of rotor part for calcium carbide fine crusher.
Background technology
Fine crusher is continuous operating equipment, and during work, under the drive of motor, rotor high-speed rotates, and it is broken that material enters the first crusher chamber, clashes into fragmentation, then enter the second chamber in small, broken bits and pulverize, finally discharge at discharging opening with epitrochanterian bar.Runnability is reliable and stable, technique simplifies, structure is simple, easy to maintenance, production capacity is large because it has for fine crusher, the feature of tup long service life, be widely used in Machine-made Sand building stones, high-grade highway, railway, water conservancy, airport, building, cement, resistance to material, the industry production high-quality building stones such as metallurgy.Fine crusher is applicable to granite, basalt, limestone, cobble, clinker, quartz, iron ore, and the thin formula of the multi mineral such as bauxite is broken.
Fine crusher is mainly divided three classes by operation principle: hammer type fine crusher, impact disintegrating machine and roller type fine crasher.Fine crusher can be divided into two classes again by profile: vertical fine cracker and Horizontal fine machine, wherein vertical fine cracker is also known as column mill.Hammer type fine crusher is divided into: horizontal hammer type fine crusher and vertical shaft type hammer type fine crusher.Horizontal hammer type fine crusher is divided into overall hammerhead fine crusher and split type hammer type fine crusher.Vertical shaft type hammer type fine crusher is all overall hammerhead fine crusher.Overall hammerhead fine crusher is commonly called as sand shaker, and tup, for forging material, is directly connected on rotor by bar, and low cost is its essential characteristic; But the scope of attack of tup is less, ability in small, broken bits is more weak, changes tup inconvenient, needs bar to extract out and could change tup.Because tup directly penetrates bar, for preventing the forced breakage of tup, therefore tup material can not be really up to the mark, causes tup wearability lower.Split hammerhead fine crusher is also called efficient fine crusher, and the maximum feature of this kind equipment is exactly that tup have employed high abrasion material, and tup wear time obtains and significantly extends; Hammer handle adopts carbon steel casting, ensure that stress performance is excellent.The tup scope of attack obtains and significantly promotes, and ability in small, broken bits strengthens, and extraction plate adopts multicomponent alloy casting, and sieve seam is optional arbitrarily, and for the material having certain humidity and viscosity, the mode that sieve seam can be adopted to regulate is improved.In addition, split type hammehead structure, makes to change tup very convenient.Vertical shaft hammer fine crusher advantage does not have extraction plate, substantially there is not blockage problem; But because material after hammering does not form effective wide-angle counterattack effect with liner plate, ability in small, broken bits is weak compared with Horizontal fine machine; Its shortcoming is tup is monolithic construction, and the tup wear-out period is shorter, changes tup comparatively loaded down with trivial details, and the difficulty changing bearing is also larger.
Impact disintegrating machine is exactly vertical shaft impact crusher substantially, or is commonly called as sand machine processed.Broken feature is exactly high-speed impact crushing, and owing to have employed the wearing piece of carbide alloy, therefore the wear-resisting cycle is longer, and production capacity can reach maximum in fine crusher.But the material size of impact disintegrating machine is subject to certain restrictions, generally can not be greater than 5-6 centimetre, need to configure more equipment.In addition, the price of impact disintegrating machine is higher, and in general operation medium and small in small, broken bits, cost of investment is higher.
Roller type fine crasher mainly contains two roller fine crusher and four roller fine crushers.Roller type fine crasher advantage is successful in small, broken bits, and returning charge rate is very low.Weak point is that the equipment failure rate occurred in Long-Time Service is higher, and maintenance maintenance is comparatively loaded down with trivial details and difficult.
Publication number is CN 203508082U, publication date is that the Chinese patent literature of on 04 02nd, 2014 discloses a kind of calcium carbide crusher rotor arrangement, comprise roller body, it is characterized in that: in described roller body, be provided with a key, roller body comprises roll shaft, roller shell, and roll shaft is wrapped up by roller shell, and the both sides of described roller shell are provided with collet, roll shaft one end connection for transmission device, and be connected by bearing, bearing block and base.
Rotor arrangement disclosed in this patent document, by in roller shell Surface Machining column type blind hole, i.e. blowhole, then be arranged in blowhole by casting nail employing press-fit approach, casting nail is over-surplus fit structure with blowhole, and casting is in actual use followed closely the impact being subject to calcium carbide and often be there will be phenomenon of rupture, once the fracture of casting nail is just difficult to change, cause whole roller shell to lose efficacy, blowhole frock difficulty is large, and processing cost is higher; In addition, casting nail irrational distribution, the occlusion space that two casting nails adjacent one another are are arbitrarily formed is little, be difficult to broken coarse crushed calcium-carbide, can not effectively carry out in small, broken bits to calcium carbide, and the calcium carbide of fragmentation be easily stuck in the space of adjacent casting nail formation, has a strong impact on calcium carbide effect in small, broken bits.
