Impact Crusher Main Parts
Impact Crusher is made up of first stage impact curtain with anvils,impact curtain adjusting rods, second stage impact curtain with anvils, rotor, blow bar ,wedge lock assembly, back-up bar, discharge opening,third stage impact plate and so on.
Impact Crusher Operation and Maintenance
Impact crusher is a machine of high rotational speed and high inertia. To make sure the crusher runs Normally , the engineer should follow several tips:
1, Make a Rigorous testing before you start the impact crusher.
2, Check the lubrication system regularly ,when the impact crusher system is running.
3, Feed the materials evenly to avoid stones of too big size and materials that can’t be crushed.
4, Change the blow bar of the impact crusher timely ,so the crusher can keep the balance for long time running.
5, There is a strong impact on the materials when the crusher is running, and the engineers should keep the machine sealed so as to stop the dust flowing into the air.
Imapct Crusher Operating principle
Impact crusher crushes materials by impact force. When materials enter the blow bar area, they are crushed due to the high-speed impact of blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be thrown 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 materials can be changed by adjusting the gap between the impact rack and rotor support. The machine 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. 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.
Imapct Crusher Characteristics
Hammer is made of high chrome;
liner board is made of wearable materials;
Specially designed tooth impact plate;
More suitable for crushing hard rock, high efficiency, low consumption;
Final products is cubic, discharge opening is adjustable;
Make the crushing flow chart simple.
