When comparing which one is more suitable for primary crushing equipment, jaw crusher or impact crusher, the following aspects can be analyzed:
1. Equipment characteristics and uses
Jaw crusher
1. Mainly used for medium-sized crushing of various ores and bulk materials, and can crush materials with a compressive strength of no more than 320Mpa.
2. It is divided into coarse crushing and fine crushing, with a feed size of 125mm~750mm, and is the preferred equipment for primary crushing.
3. It has the characteristics of deep crushing chamber, no dead zone, high feeding capacity and output, large crushing ratio, and uniform product particle size.
4. It has a simple structure, reliable operation, low operating costs, and energy-saving equipment. The single machine saves 15%~30% energy, and the system saves more than twice the energy.
5. Low noise, less dust, widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical industries.
Impact crusher
1. A common secondary crushing equipment, but the rotor and crushing chamber can also be adjusted according to user needs to be used as a primary crushing equipment.
2. Widely used in highways, reservoir projects, railway laying and airport construction, etc., and the requirements for the shape of stones are particularly strict.
3. It has the characteristics of large crushing ratio, large output and stable performance.
4. The crushed stones are mostly cubic, and there are few needle-shaped stones, which is suitable for industries with high requirements for stone shape.
2. Applicability and flexibility
Jaw crusher: As a primary crushing equipment, it has high applicability and flexibility, can handle a variety of materials, and has stable crushing effect.
Impact crusher: Although it can also be used as a primary crushing equipment, it is usually more suitable for occasions with specific requirements for stone shape. Its flexibility lies in the ability to adjust the rotor and crushing chamber according to user needs.
3. Comprehensive comparison
Jaw crusher: It has higher applicability and stability in the primary crushing stage, can handle materials with high compressive strength, and has a large crushing ratio and uniform product particle size.
Impact crusher: Although it can also be used as a primary crushing, it is more commonly used in occasions with strict requirements for stone shape. Its crushing effect is excellent, but it may be limited by the compressive strength of the material.
Jaw crusher is more suitable as a primary crushing equipment. It has high applicability and stability, can handle a variety of materials, and has a stable and reliable crushing effect. However, in certain occasions, such as when the shape of the stone needs to be strictly controlled, the impact crusher is also a good choice. When choosing, it should be comprehensively considered based on specific needs and material characteristics.
