Crushing Machinery Aggregate Processing Equipment Impact Crusher Jaw Crusher
The Impact crusher is a kind of crushing machine which uses the impact energy to break the material. When the machine works, under the drive of the motor, the rotor rotates at high speed, when the material enters the plate Hammer action area, the impact of the plate hammer on the rotor is broken, and then it is thrown back into the counterattack device to break again, and then from the counterattack liner to the plate Hammer action area again broken, this process repeats, the material from large to small The three counterattack cavities are repeatedly broken until the material is broken to the desired granularity and discharged by the outlet. For ease of understanding, the crushing equipment factory store uses a more intuitive dynamic diagram to demonstrate, as shown in the right image.The stone falls directly from the top of the machine into the high-speed rotating turntable; Under the action of high speed centrifugal force, with another part of the parachute shunt in the turntable around the flying stone to produce high-speed collision and high-density crushing, stone in each other hit, but also between the turntable and the chassis to form Eddy current movement caused by multiple strikes and shredding.
The impact crusher has the advantages of the following five aspects in the process of crushing,
First, the impact crusher to deal with large amounts of wet materials more effective, effectively prevent material blockage. When the water content of the material is too large, the feed chute and the impact plate of the impact crusher can be equipped with heating device to prevent the bonding of the material.
The counterattack crusher should not be equipped with a bottom sieve plate to effectively prevent blockage.
Second, the counter-type crusher suitable for the material hardness is more extensive. The plate hammer of the counterattack crusher is firmly fixed on the rotor by means of a mechanical clamping structure, which has a great moment of inertia when rotating with the rotor.
Compared to the Hammer crusher (the hammer head is overhanging), the rotor of the counterattack Crusher has greater momentum, adapts to the crushing of harder materials, and the energy consumption is lower at the same time.
Third, can be convenient and flexible adjustment of the granularity of the material, a wide range of adjustment The counterattack crusher can adjust the particle size of the material in a variety of ways, such as adjusting the rotor speed, adjusting the gap between the counterattack plate and the grinding cavity.
Gap adjustment can be adjusted by mechanical or hydraulic type, the use of hydraulic regulation system can be easily achieved through the in-place Operation button or transport control system to complete the adjustment of clearance.
Iv. wear of wearing parts is small, high metal utilization rate The wear of the hammer of the counterattack stone-breaking machine appears only on one side of the welcome material. When the rotor speed is normal, the feed will fall to the surface of the plate hammer (hit surface), the back and side of the plate hammer is not worn. Even the wear and tear on this side of the material is rarely worn. And the bottom grinding rod is easy to replace.
The metal utilization rate of the counterattack crusher plate hammer can be as high as 45%-48%.
V. The replacement of spare parts for counterattack crusher is simple and the maintenance cost is reduced accordingly
Only 6 plate hammers are installed on the rotor of the counterattack crusher, and the special tools designed can be used to replace the plate hammer easily, and it takes only one shift time to replace a set of plate hammers.
Counterattack crusher is mainly used in metallurgy, mining, cement, chemical industry, refractories and ceramics and other industrial sectors, as well as highway construction, water conservancy projects, building gravel, mechanism sand processing and other fields. Because of the characteristics of its wearing parts, the application of counterattack crusher on materials with high hardness is limited, which is more suitable for coarse, medium crushing and fine shredding of various soft and medium hard ores, such as: lime
