Impact crusher and hammer crusher are our commonly used medium and fine crushing equipment. Many users will ask when purchasing, which of the two equipment is better and more suitable for use, and what is the difference between them. If you don't know the difference between the two, then follow this blog and read it together, it will take you to learn in detail.

Next, we will take the impact crusher and hammer crusher of Shandong Bond Heavy Industry Technology Co., Ltd. as an example to explain in detail. Bond Heavy Industry's impact crusher is PF series, and the hammer crusher is PC series.

PF impact crusher is mainly used for material processing that often requires relocation operations in metallurgy, chemical industry, building materials, hydropower, etc., especially for operations of mobile stones such as highways, railways, and hydropower projects. It can be configured in a variety of forms according to the type, scale and requirements of finished materials of processed raw materials. It is often used to crush limestone, limestone, and concrete with relatively low hardness. The impact crusher can handle materials with a side length of less than 500 mm, with a compressive strength of up to 350 MPa, a large crushing ratio, and cubic particles after crushing. It is widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical industry and other industries for medium and fine crushing of materials. The discharge particle size can be adjusted, and the crushing specifications are diversified.

PC hammer crusher, with an output of 100~3000 tons per hour, has a large crushing ratio, less over-powdering phenomenon, uniform product particle size, and once broken into shape, plus a vibrating screen, it is a production line. It is the preferred equipment for the stone crushing industry, especially the sand and gravel aggregate production line.

The heavy hammer crusher can crush limestone, coal gangue, dolomite, gypsum, bricks and tiles, coal and other medium hardness and brittle materials with a compressive strength not exceeding 200MPa. It is suitable for industrial sectors such as metallurgy, building materials, chemicals and hydropower. It has low energy consumption, reasonable price, hammer plate edge protection structure, and increases the service life by 4~6 times. It is very popular among users.

Difference:

Scope of application:

The impact crusher is suitable for medium and fine crushed materials with a compressive strength not exceeding 350 MPa, which is commonly known as secondary and tertiary crushing. It is widely used in highway construction, water conservancy projects and building materials. It is an ideal equipment for aggregate processing. Applicable stones include limestone, limestone, coal gangue, etc.

Hammer crusher is mainly used in cement, chemical, metallurgy, coal and other industries, suitable for medium hardness and brittle materials. Applicable stones include limestone, coal gangue, coal, dolomite, etc.

Crushing principle:

Both impact crusher and hammer crusher adopt the impact crushing method, and the material is ground and impacted by wear-resistant parts to form crushing.

The difference is that the impact crusher uses the inertia of the rotor assembly to impact the material against the trend, which can be divided into three ways: free crushing, impact crushing, and grinding crushing. The hammer crusher uses the hammer head to hit the material for the trend crushing, which can be divided into two ways: free crushing and impact crushing.

Internal structure

The impact crusher is composed of a cavity, a rotor assembly, an impact plate and other parts. The material enters the crushing cavity, the rotor keeps running, the material first hits the impact plate, and then is hit by high-speed impact on the impact liner, and the repeated movement is crushed.

The hammer crusher is composed of a box, a rotor, a hammer head, a liner, a leak plate and other parts. The material is crushed under the high-speed rotating hammer head, rebounds and hits the side guard plate, qualified materials are discharged through the leak plate, and unqualified materials continue to remain in the crushing chamber for crushing.

Wear-resistant parts

The wear-resistant parts of the impact crusher mainly include plate hammers, impact plates, impact liners, etc. Relatively speaking, the wear-resistant parts of the impact crusher have less loss. The wear-resistant parts of the hammer crusher are mainly hammer heads, side guard plates, etc. The hammer heads are the fastest worn of the hammer crusher and are replaced more frequently.

Finished product effect

The particle shape of the impact crusher is better, and its aggregate is cubic, which can meet the applicable requirements of high-quality concrete. The impact crusher also has a certain shaping effect when crushing. The finished particle shape of the hammer crusher is mostly flake-shaped and has a high powder content.

Summary:

Through the comparison of the applicable scope, crushing principle, internal structure, wear-resistant parts, and finished product effects of the impact crusher and the hammer crusher, it can be seen that the two machines have their own advantages and disadvantages. The specific choice depends on the specific needs and actual situation of the customer. Bond Heavy Industry has been focusing on the stone crushing and sand making industry for 30 years.
