What is an impact crusher?
An impact crusher is a machine that uses the principle of impact crushing to crush raw materials. It is commonly used in industries such as ore crushing, railways, highways, water conservancy, building materials, energy, cement, chemicals, and construction waste crushing for low-hardness stones or materials with a compressive strength not exceeding 150MPa. It has advantages such as high efficiency and energy saving, high output, low wear, and good product particle shape.
Impact crushers are often used as primary or secondary crushers in the crushing process. Compared to jaw crushers, they produce finer crushed materials. A superior impact crusher is the SUHMAN SF-380D-2S model, which incorporates the advantages of screening machines, capable of screening crushed materials into three particle size ranges, suitable for investors with limited budgets.
In recent years, impact crushers have been increasingly used in the concrete crushing industry. If you are planning to invest in construction waste recycling and concrete crushing, you can read this article as a reference.
Working principle of impact crusher
The impact crusher uses a heavy-duty super rotor. Stone material falls directly from the feed inlet onto a high-speed rotating disc within the large-capacity crushing chamber. Under high-speed centrifugal force, it collides at high speed with and is crushed at high density by a portion of flying stones that are dispersed in an umbrella-like pattern around the disc. After mutual impact, the stones form vortex motion between the disc and the casing, resulting in multiple impacts, friction, and crushing, before being discharged directly from the bottom. This forms a closed-loop, multi-cycle process, with the required particle size controlled by screening equipment.
How to Choose a Suitable Impact Crusher?
Select a suitable impact crusher based on the project size, as follows:
For small projects, with a capacity of less than 100 tons per hour: A 1214 impact crusher can be selected. Many manufacturers use 1214 impact crushers, such as the SUHMAN SF-380D mobile crusher, with a capacity of 150-240 TPH. The specific capacity depends on the type of raw material and the particle size range of the finished product.
For medium to large-scale projects with a capacity of 200 tons per hour or more: a 1315 impact crusher main unit can be selected, such as the SUHMAN SF-580D, with a capacity of 150-350 TPH. The specific capacity depends on the type of raw material and the particle size range of the finished product.
Generally, a crushing project does not only use an impact crusher. The choice depends on the type of raw material and the particle size range of the finished product. For example, in the solid waste recycling industry, it is often recommended to use a jaw crusher for primary crushing and an impact crusher for secondary crushing, or vice versa, with an impact crusher for primary crushing, a cone crusher for secondary crushing, and a 7018 screening machine for tertiary screening. For specific situations, it is advisable to consult several professional crusher manufacturers to develop a plan and compare options.
Important Considerations When Purchasing a Crusher
There are countless crusher manufacturers on the market. If your budget allows, it is recommended to choose crushers from European countries. They have a long history of manufacturing crushers and have many after-sales service centers in Europe, ensuring that you can quickly contact the supplier if after-sales issues arise.
If your budget is limited, we recommend choosing a Chinese crusher manufacturer. We suggest Anhui SUHMAN Crusher Manufacturer. Firstly, they have many overseas clients and extensive international sales experience. They include spare parts with every shipment and offer a 2-year warranty, ensuring worry-free after-sales service. Secondly, they are a subsidiary of a Chinese military factory, and their crushers meet military-grade quality standards, a level of quality that many other manufacturers struggle to match. If you are interested in impact crushers or investing in the sand and gravel aggregate industry, you can contact SUHMAN for a free consultation. Thank you for reading and choosing us!
