Hammer Crusher VS Impact Crusher, Which Is Better?


Which is better, hammer crusher or impact crusher? This is a question that many people are entangled in when purchasing crushing equipment. Since both impact crushers and hammer crushers use high-speed impact to crush materials, and have similar appearances and rotor structures, many people think that there is not much difference between the two types of equipment, so they are in a dilemma when purchasing. In fact, these two types of crushers have their own advantages and disadvantages in terms of crushing capacity, finished product particle size, and scope of application. The following is a detailed analysis.

1. Crushing Chamber

 
The crushing chamber of the hammer crusher is small and has good structural sealing, which can reduce dust pollution and body ash leakage when crushing materials.
 
The crushing chamber of the impact crusher is relatively large, and the feed inlet is low and large. In this way, after the material enters the crushing chamber, it can collide with the impact plate repeatedly, and the force is more sufficient, so that large pieces of material can be better crushed and the crushing efficiency is higher.


2. Finished Product Size

 
The hammer crusher adjusts the finished product size by adjusting the size of the sieve plate gap, so the finished product size is small and mostly in powder form.
 
The impact crusher can adjust the product size by adjusting the rotor speed or diameter, the size of the distributor opening, so the finished product size is uniform, generally in a cubic shape, and has low dust content.
 

3. Scope of Application

 
The hammer crusher is suitable for crushing soft and easy-to-crush materials, such as coal, gypsum, limestone, etc. It is also suitable for crushing broken wood and paper with strong fiber structure, elasticity and toughness. It is mostly used in cement production lines or as limestone raw material crushing equipment, and can also serve as primary crushing equipment in sand and gravel co-production projects.
 
The impact crusher is suitable for most of the mine stones with low iron content in various coarse, fine and medium hard materials, and is mostly used as secondary crushing equipment in the crushing production line. At the same time, due to its uniform finished product size, it is widely used in railways, highways, and energy industries. For example, the anti-skid pavement of high-grade highways usually uses an impact crusher as the final crushing equipment to produce concrete aggregates.


4. Cost
 

Due to the simple structure and operation of the hammer crusher, it does not require primary and secondary crushing, and is formed in one step. It is cheap and has a low initial cost. However, the rotor hammer plate and end plate are easy to break, and the replacement of parts in the later stage also requires investment.
 
Relatively speaking, the price of the impact crusher is higher than that of the hammer crusher, and the initial investment cost is relatively high. However, it has a large crushing ratio, high crushing efficiency, strong interchangeability between parts, and fewer types of wearing parts, which reduces the occurrence of failures in the later work process. In the long run, the impact crusher is also a good choice.

Through the above analysis, we hope that users can better understand the advantages and disadvantages of hammer crusher and impact crusher, and choose the equipment suitable for their own projects.
