Which is better, hammer breaking or counter breaking? This is a problem that many users struggle with when purchasing crushing equipment. Since impact crushers and hammer crushers both use high-speed impact to crush materials, and have similar shapes and rotor structures, many people think that there is not much difference between these two types of equipment, so that when purchasing Dilemma. In fact, these two kinds of crushers have their own advantages and disadvantages in terms of crushing capacity, finished product size and scope of application, etc., which will be analyzed in detail below.

Impact Crusher
1. Crushing cavity
The crushing cavity of the hammer crusher is small, and the structure is better sealed, which can reduce dust pollution and dust leakage from the body when crushing materials.
The crushing cavity of the impact crusher is relatively large, and the feeding port is low and large. In this way, after the material enters the crushing cavity, it can repeatedly collide with the impact plate, and the force is more sufficient, so that the large material can be crushed better. higher efficiency.
2. Finished product particle size
The hammer crusher adjusts the particle size of the finished product by adjusting the gap size of the sieve plate, so the particle size of the finished product is small and more powdery.
The impact crusher can adjust the particle size of the product by adjusting the speed or diameter of the rotor and the opening size of the distributor, so the particle size of the finished product is uniform, generally in the shape of a cube, and the dust content is low.
3. Scope of application
Hammer crusher is suitable for crushing soft and easily broken materials, such as coal, gypsum, limestone, etc., and 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 be used 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, because of its uniform particle size, it is widely used in railways, highways, and energy industries. For example, on the non-slip pavement of high-grade highways, impact crushers are usually used as final crushing equipment to produce concrete aggregates.
4. Input cost
Due to the simple structure and operation of the hammer crusher, there is no need for primary and secondary crushing, one-time molding, cheap price, and low initial cost, but the rotor hammer plate and end plate are easy to break, and later replacement parts also require investment costs.
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, it is hoped that users can better understand the advantages and disadvantages of hammer crusher and impact crusher, and choose equipment suitable for their own projects. If you still have doubts and can’t start, you can click to consult the price, and we will arrange good engineers to answer your questions, design high-efficiency production lines, and select or customize high-efficiency equipment.
