Impact crusher vs jaw crusher are common crushers, which are widely used in metallurgy, chemical industry, building materials and material crushing. There are many similarities between them, but at the same time, there are also many differences. This article mainly introduces the difference between impact crusher vs jaw crusher.
What is an impact crusher
The impact crusher is mainly used for metallurgy, chemical industry, building materials, hydropower and other materials that often need to be relocated. It is especially suitable for the work of mobile stones in highways, railways, and hydropower projects. It can be processed according to the type, scale and finished product of the material. Various configuration forms are used depending on the material requirements.
What is a jaw crusher
Jaw crusher is a relatively early crushing machine, its structure is simple, strong, reliable, easy to maintain and overhaul. It mainly consists of two jaw plates, movable jaw and static jaw, to form a crushing cavity, which simulates the movement of the two jaws of animals to complete the material crushing work. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, roads, railways, water conservancy and chemical industries.
The difference between the structure of impact crusher vs jaw crusher
The impact crusher is composed of rotor, plate hammer, strike plate, frame, impact plate and transmission parts, and the strike plate is rigidly connected to the rotor.
The structure of jaw crusher is mainly composed of frame, eccentric shaft, flywheel, movable jaw, fixed jaw, side guard, toggle plate and return spring, and the toggle plate also plays an insurance role.
The difference between the crushing cavity of impact crusher vs jaw crusher
The crushing cavity of the impact crusher is relatively large, so that the material has sufficient space for movement, and the impact of the crusher can be fully utilized.
The crushing cavity of the jaw crusher has a simple structure, which can crush oversized materials. After the mutual extrusion of the movable jaw and the fixed jaw, the crushed materials are discharged out of the crusher.
The difference between impact crusher vs jaw crusher
The plate hammer and the rotor of the impact crusher are rigidly connected, and the inertia of the entire rotor is used to impact the material, so that it is not only broken but also obtains greater speed and kinetic energy.
The crushing method of the jaw crusher is to crush by the movable jaw and the fixed jaw. After the material enters the crusher through the feed port, it is directly extruded by the movable jaw and the fixed jaw. After extrusion, the material is directly discharged from the crusher.
The difference between the accustomed materials of impact crusher vs jaw crusher
The impact crusher is mainly used for secondary crushing of gypsum stone, coal gangue, limestone, cobblestone, sandstone and quartzite.
The jaw crusher is mainly suitable for the first crushing of various ores. Its feeding port is large and easy to operate. It is widely used in various ores and large pieces of mining and smelting, building materials, roads, railways, water conservancy and chemical industries. Broken material.
The difference between impact crusher vs jaw crusher
Due to the limitation of its own crushing conditions, although the particle size of the ore material after being crushed by the jaw crusher is uniform, the overall particle size is too large, so for users with higher requirements, when choosing a crusher, it is necessary to consider Add some other crushers.
Different from the jaw crusher, the impact crusher not only has high crushing force, but also has the function of stone shaping. Therefore, the materials processed by the impact crusher are mostly cubes with reasonable gradation, which can meet various requirements. crushing work requirements. Therefore, in the production of some crushing work, two types of crushers are often used in combination.
The difference between the performance of impact crusher vs jaw crusher
The impact crusher has the advantages of large feeding port, high crushing cavity, high material hardness, large block size, and less material stone powder; the gap between the impact plate and the hammer can be easily adjusted, effectively controlling the discharge particle size, and the particle shape is good; the structure is compact, The machine has strong rigidity, and the rotor has a large rotational inertia; high-chromium plate hammer, anti-impact, anti-wear, and large impact force; simple machine connection, convenient maintenance, economical and reliable; full crushing function, high productivity, low wear and tear of machine parts, comprehensive efficiency high.
The jaw crusher has a deep crushing cavity and no dead zone area, which improves the feeding capacity and output; its crushing ratio is large, and the product particle size is uniform; the gasket-type discharge port adjustment device is reliable and convenient, and the adjustment range is large, which increases the number of crushers. flexibility; simple structure, reliable work and low operating costs. The crusher is energy-saving and has a large adjustment range of the discharge port, which can meet the requirements of different users; low noise and less dust.
The difference between the working principle of impact crusher vs jaw crusher
When the impact crusher is working, driven by the motor, the rotor rotates at a high speed. When the material enters the action area of the blow hammer, it collides with the blow hammer on the rotor and breaks, and then is thrown to the impact device to be broken again, and then from the impact crusher.
The impact liner bounces back to the action area of the blow hammer to be broken again. This process is repeated. The materials enter the first, second and third impact chambers from large to small for crushing until the materials are crushed to the required particle size and discharged from the discharge port.
When the jaw crusher is working, the motor drives the belt and pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw.
In this process, the material is crushed or split to achieve the purpose of crushing; when the movable jaw goes down, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the pull rod and spring, At this time, the crushed materials are discharged from the lower opening of the crushing chamber. With the continuous rotation of the motor, the crushing jaws perform periodic motions to crush and discharge materials to achieve mass production.
The difference between the working range of impact crusher vs jaw crusher
The finished product of the impact crusher is cubic, without tension and cracks, and the particle shape is relatively good. It can crush various coarse, medium and fine materials (such as Granite, limestone, concrete, etc.), the particle size of the discharge can be adjusted, and the crushing specifications are diversified.
The jaw crusher is mainly used for medium-sized crushing of various ores and bulk materials. It can crush materials with a compressive strength of not more than 320 MPa. It can be divided into two types: coarse crushing and fine crushing. There are various types of jaw crushers, which are suitable for primary crushing of various granular materials.
The difference between impact crusher and jaw crusher in use
Jaw crushers are generally used for primary crushing, which is to crush large materials into a material size suitable for secondary crushers. The feed of secondary crushers is generally very small. If the feed is large, it must be used. Jaw crusher is used as primary crushing, and impact crusher generally crushes marble and granite. Too hard materials are not suitable for impact crusher. If it is too hard, it will cause great loss of wearing parts of the crusher.
In general, the impact crusher has superior performance and is mainly suitable for medium and fine crushing, so the particle size of the product is also more uniform. The jaw crusher is a crushing machine designed for various hardness rocks, mainly suitable for primary and secondary crushing.
