Type PF impact crusher is the newest generation product designed by our company after absorbing the advanced technology in the domestic and foreign, according on concrete industry and mining condition of domestic sand and crushed stone profession industry.
It uses the newest technique of manufacture, the unique structural design, the processing end product is to be cube, unstressing and unstretching, quite good grain shape,it can stave every kinds of thick,thin materail (granite, limestone, concrete and so on) which the feed granularity is not to surpass 500mm, the compressive strength stave does not surpass 350Mpa. It is widely applies in each kind of ore stave, such as highway , railroad, energy, cement, chemical industry, building and so on .Its dump granularity size can adjust, stave specification is diversificate.
The single rotor impact crusher has the characteristics of simple structure, big reduction ratio, low energy consumption l, high output , light weight, cubic physique end product.
it can supply the uses of industry sectors such as dressing, chemistry, cement, building, fire-proof material, ceramics, glass to use in hitting garrulous and each kind of medium degree of hardness using of in broken bits material, for example: Limestone, chamotte, slag, coke, coal and so on.
Compare to hammer crusher,impact crusher has bigger reduction ratio and Can fully use the high speed impact energy of entire rotor. But because the impact crusher board hammer is extremely easy to wear, it also is restricted in the hard material stave application.impact crusher is usually used to break thick garrulous, garrulous or the limestone, the coal, the calcium carbide, the quartz, the dolomite, the curing iron ore, the gypsum and the industrial chemicals which are hard following brittle material.
The ideal entering material granularity of this series is 100-500mm,the most greatly is not surpass the rating. The materail granularity user can ajusts the hammer head and the impact board and th gap between component,according to theirs demands.Working principle of Impact Crusher:
The impact crushe materials with impact force. When the materials enter the blow area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The impact crusher employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.
Characteristics of Impact Crusher:
1.The impact crusher with Big feed head ,high stave cavity,high adaptation material degree of hardness,big block,few product stone powder.
2.The impact board and the board hammer gap can be facilitatly adjusted, the controlment material granularity is active, the grain shape is good.
3.The structure of the impact crusher is compact, the machine rigidity is strong, the rotor has the big rotation inertia.
4.Hammer is anti-impact, anti-attrition, the impulse is big.
5.No keying, the overhaul is convenient, the economy is reliable.
6.Entire stave funtion ,high productivity,slightly parts wears and tears,high combined earings.
7.In the strucure desigh of the imapct crusher,it has three sections of stave areas which are unique vortex stave cavity and P, S, T.
8.The rotor system of the imapct crusher uses the non-key taper sleeve joint, the highly effective wear-resisting board hammer, the insertion installment form, the inclined bearing seat.
9.Unique tooth profile counter-attack backing, the rack opens the door to multi-positions.
10.the hydraulic pressure opening installment causes the replacement vulnerably and the overhaul to be more convenient.
11.The impact crusher is Especially for the hard crag stave, high effective energy conservation.
12.Final products of the impact crusher is cubic, the dump granularity size is adjustable,to make the crushing flow chart simple.
13.Hammer is made of high chrome.
14.Liner board of thei impact crusher is made of wearable materials.
15.Discharge opening of the impact crusher is adjustable.
16.High reduction ratio and crushing efficiency.
18.The blow bar with high chrome (high chromed blow bar).
19.Impact plate with a special shape.
20.Crushed product with cubical shape.
21.The imapct crusher with Easy maintenance and reliable operation.
Impact crusher is applies to such materials whose length of side does not surpass 500mm, the compressive strengh does not surpass 260Mpa. It is better to granite, the limestone, the river pebbles, and so on.Main technical data:
