Description
Technical field
The invention belongs to equipment for pulverizing material fields, and in particular to a kind of vertical shaft crusher and its breaking method.
Background technique
Traditional vertical shaft crusher includes high-speed rotating rotor and crusher chamber etc. centered on vertical axis, and investment is broken
Material in machine, which impinges upon to collide around to be crushed on indoor material lining by rotor, is broken into fine grained, from broken
For the material slid on the bed of material of room by the gap discharge between rotor and crushing chamber grommet, this smashing principle is broken for vertical shaft impact
" stone-crash-stone " smashing principle of broken machine.Material with investment vertical shaft impact crusher increases, the original being deposited in crusher chamber
Material is continuously increased, the material of finished breaking chamber under the effects of rotor throws away the cohesive force between the impact force of material and material
Stable material lining is formed in crusher chamber；When continuing growing the inventory in investment crusher, accumulated in crusher chamber
Material lining volume is continuously increased, and the cohesive force between material lining is not enough to carry self gravity and rotor throws away hitting for material
Power is hit, " snowslide " phenomenon of the bed of material finally occurs, a large amount of material can be got lodged in suddenly between rotor and the annular liner plate of crusher chamber,
It causes rotor to be blocked, the driving source energy consumption of rotor is driven to increase suddenly, or even rotor " being blocked situation " occur.
In order not to the case where above-mentioned rotor is blocked occur, crusher exchanges crusher for as cost to reduce input amount at present
Stable operation.The reduction ratio and treating capacity of vertical shaft impact crusher are contained powder by material properties, such as hardness, partial size, sandstone simultaneously
The influence of the parameters such as rate or moisture content is bigger, and when these parameters change, the material lining in crushing chamber can get over heap
Product is more, eventually leads to the unexpected slump of material lining, and rotor is blocked, and it is that cost exchanges for broken that conventional breakers, which are also to reduce investment,
The stable operation of broken machine.
To solve the above-mentioned problems, also occurred the vertical shaft crusher using the vibration of entire crusher chamber on the market, but should
The crusher of type requires height to the production of crusher and mounting condition, and with the increase of crusher input amount, the vibration is broken
The processing capacity of broken machine and reduction ratio increase are very small, and are improving treating capacity side to the vertical shaft impact crusher of high throughput
Face is not applicable, is further improved.
Summary of the invention
The purpose of the present invention is overcoming the prior art, a kind of vertical shaft crusher is provided, another object is to provide
