Description

Vertical cone pulverizer

The utility model relates to a kind of disintegrating apparatus, leads the fine crusher of hardness material in especially a kind of suitable fragmentation.

In prior art, the kind of disintegrating machine is a lot, and during broken various medium-hard material, all is to adopt jaw crusher usually, impact breaker, vertical-spindle hammer crusher or gyratory crusher etc.As vertical-spindle hammer crusher is to be used for production processes such as asbestos ore and cement industry, its characteristics adopt three or four measure-alike cylindrical superposed type breaking chamber structures, its better performances, but also have the rational inadequately shortcoming of structural design, for example, its top crusher chamber tup bears that load is big, and it is too fast wear and tear, and its underpart crusher chamber tup bear load little, wearing and tearing are slight, perform practically no function, fail to give full play to the effect of its broken material, cause the waste of energy.The garden conic crusher is to constitute " V " shape crusher chamber by mantle and fixed awl, mainly be mantle and bore work surely, crumbling method is that material is squeezed between fixed awl and mantle with crooked broken, this disintegrating machine adopts " V " shape crusher chamber, selective crushing ability to material is strong, and is extremely strict to strength of machine body and rigidity requirement, its equipment complexity, maintenance is inconvenient, the cost height.

The utility model designs in order to overcome above-mentioned weak point, it mainly is on the basis of the mechanism of the various disintegrating apparatus of research and characteristics, the characteristics of using for reference vertical-spindle hammer crusher and garden conic crusher design, purpose is to provide a kind of ratio of reduction bigger, energy-conservation, equipment in small, broken bits efficiently for broken material, particularly in the production process of cement industry, employing small grain size technology in small, broken bits, " to break the generation mill " can energy-conservation significantly and raising output.The utility model is a kind of improvement design, mainly the disintegrating machine internal structure is designed to three crusher chamber, promptly by epicoele, cavity of resorption and intermediate cavity are formed, its epicoele and cavity of resorption are the garden cylinder chamber, and cavity of resorption is littler than epicoele size, intermediate cavity is " V " shape chamber, these three crusher chamber are organically superimposed, constitute the structure vertical in small, broken bits of an optimization, its main feature is to have strengthened the size of epicoele and tup emphatically, and this has just relatively reduced the breaking strength of epicoele, has prolonged the service life of tup significantly, intermediate cavity adopts " V " shape chamber, its tup also correspondingly changes the structure of arc into, and intermediate cavity is designed to " V " shape, is in order to strengthen the selective crushing ability to material, strengthen the internal impact and the friction of material, strengthened fragmentation, the broken space of epicoele maximum, and the space minimum of cavity of resorption to material, thereby the balanced breaking strength of three crusher chamber has improved tup life-span and operation rate.Epicoele mainly plays the coarse crushing effect, it has determined the production capacity of conical vertical fine crusher, and in, cavity of resorption is further material in small, broken bits, counterpunch board in each crusher chamber is fixing with arc-shaped partition, dividing plate can play the effect of counterattack material again, has therefore strengthened the autoclasis of material, has increased the time of staying of material in machine, improved the crushing effect of material, this structure had both been coordinated and rationally.
