Impact Crusher vs Hammer Crusher

Impact Crusher vs Hammer Crusher

What’s the difference between impact crusher and hammer crusher? Impact crusher vs hammer crusher. For details, see the back of the content.

Impact crusher involves the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor. There are two types: horizontal shaft impactor and vertical shaft impact crusher.

Hammer crusher is equipment which in the form of impact crushing materials. The divided into the single rotor and double rotor two forms. The maximum particle size of 600-1800 mm of material will crush to 25 or less than 25 mm directly. Hammermill is suitable for crushing medium hardness materials. Such as medium crushing and finely chopped working of limestone, slag, coke, coal, and other materials.

1. The impact machine has a high crushing ratio and good shape of finished products.

1.1 The crushing ratio of the impact stone crushers can reach more than 50. And the particle shape of the finished product is good. Under the impact action, the broken material is often along its most vulnerable layer surface. At this selective crushing method, the material size is even, the material is the cubic shape. And the fine powder and the dust content is low. The high-grade Highway skid-proof pavement uses it as the final breaking equipment to produce usually.

1.2 The crushing ratio of Hammer-crusher is small. And the product has more granular needle-like content, high powder content, low crushing efficiency, and low yield.

2. The crushing parts of impact are simple and maintenance costs much less.

2.1 the frame of the impact-crushers is a three-part structure. Then it is only necessary to open the back shell of the crusher to replace the Hammer, the impact plate, the lining plate, and other maintenance operations. And the interchangeability of the parts of the machine is strong. The variety of fragile parts is less, which is convenient for the purchase and manage.

2.2 There are more than 100 Hammerheads in the Hammermill crusher. It takes a lot of time and manpower to replace one set of hammerheads. The cost of overhaul and maintenance is high. And the replacement of the bottom sieve plate is also extremely troublesome.

3. The wear of the vulnerable parts is smaller than hammers, and the metal utilization rate is higher.

3.1 The wear of the impact crushing plate hammer only appears on the side of the material. The metal utilization ratio can reach 45%-48%.

3.2 the hammerhead is in the state of hanging, and the wear occurs on the upper, front, back and side. Compared with the Board Hammer, wear is more serious. The utilization rate is only about 35%. And the rotor body itself may also be subject to wear. The bottom screen plate is seriously affected by wear and tear. The screen grating should be completely replaced and more complex.

4. The impact crusher machine can conveniently adjust the discharging particle size and in a wide range.

4.1 The impact rock crusher can adjust the discharging particle size in many ways. Such as adjusting the rotor speed, adjusting the clearance between the impact plate and the Hammer, etc.

4.2 The hammers only adjust the discharging size by changing the bottom screen plate.

5. The impacts are suitable for both soft and very hard materials.

5.1 The plate hammer of the impact machine is fixed on the rotor. It can make full use of the energy of the whole rotor when crushing and is favorable for crushing large materials. Because it has an impact plate and bigger crushing cavity. The crushing not only depends on the impact of Hammer but also on the repeated impact between material and counter plate or between material and material.

5.2 The momentum of the hammer equipment rotor is less, and can not crush more rigid materials. The energy consumption is higher.

6. Impact crushing can effectively deal with the greater moisture content of materials, to prevent the crusher blocking phenomenon.

6.1 There is no grate bar at the bottom of the impact machines. The particle size of the product is determined by the clearance between the impact plate and the hammerhead. It can avoid blocking when the moisture content of the material is too high.

6.2 Hammer machine has a bottom screen plate, which increases the possibility of clogging.

To sum up, if the materials require high, humidity high and output is large, then must choose impact crushers. If the output requires low (less than 30 tons per hour), and no requirement on the finished grain shape can be used hammer crusher.
