Comparison between jaw crusher and impact crusher

Comparison between jaw crusher and impact crusher

1. Jaw crusher

Jaw crusher works: Motor drive belts and pulleys, through the eccentric shaft moving jaw up and down movement, when the moving jaw up when the bracket and moving jaw angle between the larger, so as to promote the movable jaw to the fixed jaw approach, with its While the material is crushed or broken pieces to achieve the purpose of broken; when the moving jaw down, the bracket and moving jaw angle becomes smaller, the movable jaw in the rod, under the action of the spring, leaving the fixed jaw, this time has been broken The material is discharged from the lower chamber of the crushing chamber.

Simple structure, reliable operation, low operating costs; low noise, less dust; nesting mouth adjustment range, can meet the different needs of different sizes, easy to operate, easy maintenance; User requirements.

Jaw crusher use: for the mining, smelting, building materials, roads, railways, water quarry and road construction and other industrial sectors specifically designed rock crusher.

2. Impact crusher

Impact crusher works: work, driven by the motor, the rotor high-speed rotation, the material into the post, with the rotor plate hammer impact crushing, and then back to the liner to break again, and finally discharged from the discharge port .

Crusher, high efficiency and energy saving; The shape of the product is cube, the size of the granule can be adjusted, and the crushing process is simplified. Features: 1. The structure is unique, no-key connection, high chrome board hammer.

Impact crusher use: can handle a side length of not more than 500mm, compressive strength of not more than 350MPa of coarse, medium and fine materials (granite, limestone, concrete, etc.), widely used in hydropower, highway, artificial aggregate , Broken and other industries.

New Impact Crusher

New Impact Crusher

Impact crusher is usually used in the crushing operations, in order to ensure high production efficiency, low cost and less dust, impact crusher performance and stability has become a key point of mine production. Impact crusher is an efficient crushing equipment to meet the people gradually improve the production requirements, small size, simple structure, high rate of reduction, high efficiency and environmental protection. Impact crusher equipment with new design concepts and advanced technology to meet the different hardness of the crushing requirements of various materials, in line with "more broken less grinding," the new technology requirements.

The hammer and impact plate of impact crusher are easy to wear and tear, but with the appearance and successful application of the new wear-resistant material, the abrasion of the crusher is affected, the wear resistance of the parts is improved and the service life of the equipment is prolonged. Relying on these advantages, impact crusher has become a popular crushing equipment. Stability, high efficiency and environmental protection make the impact crusher successfully applied in the production line. Excellent impact crusher should have certain conditions, such as the cause of plate hammer structure, a unique impact plate, no key connection, long life and so on.

After optimization, the impactor crusher rotor backplane can withstand higher rotational inertia of the rotor and a stronger plate hammer impact crushing force. The impact crusher is designed to have lower rotational speed and higher crushing cavity. Compared with the ordinary impact crusher, the new impact crusher linear velocity decreased by 20% to 25%, with lower energy consumption, and achieved a higher production capacity.

Impact crusher blow bar

Impact crusher blow bar

According to statistics, the main form of corruption against the lever is loose and fracture, reinforced when the following loose or break, causing the bolt fracture strike, it will damage the rotor or rack, and sometimes damage to the rotor and the main bearing. And cost against the bar very much, if we can find out the cause of this phenomenon, we can do better to improve and maintain observation of this phenomenon. Three flow is impact crusher jaw damage cause analysis:

Article blow bolt quality. Due to the poor quality of the bolts, they often loose and break, which will cause blowing rod loose or break. The most fundamental reason is that small factory bolts models have been used for many years, wear and tear becomes larger, the overall head bolts use in poor contact and cause loose. Meanwhile, in the processing line, sewing thread, to make it easier for cooperation, it will be some deliberate reduction of tooth shape, which reduces the ability of the fastening bolts.

Against quality bar itself. Touted as ZGMn13, from the fracture, the obvious pores, even empty, indicating the presence of poor quality casting, heat treatment. This is the main reason for the fight against corruption in the bar.

Improper operation and maintenance. When blown rod breakage of work, we visited SBM company was informed that since it is difficult to exchange blow after blow to the new pole installation, you should stop and check if it has loose and tight tight.

According to the above problem, they need to build a new model of the bolt, the bolt head and the blow rod oval hole can contract a good contact with the surface. At the same time, controlling the thickness of thread, dimensional tolerance, screw unloaders finishing tank, to prevent stress concentration and fracture.

Impact crusher specifications

Impact crusher specifications

Impact crusher is the result of our ongoing efforts, as well as having the characteristics of low energy devices and advanced concepts of foreign advanced technology research and development. Gravel equipment construction standards are not the same, the material needs and the fineness of the material is not the same preferential access to the vertical shaft impact crusher. With the building standards increasingly high standards of aggregate production will also advance this technology to promote the continuous development of gravel equipment, so new mechanisms, such as sand sand device appears.

SBM careful design and manufacture of vertical shaft impact crusher is a world leader in technology, high efficiency, high reliability and high-quality sand. Especially PCL impact crusher (sand making new) introduced in the field of water conservancy and hydropower projects, roads, railways, bridges, construction sand, stone fruit shape, construction aggregate, road fabric, cement concrete aggregate production; in former mining areas of crushing grinding process, the preferred device thermal power desulphurization metallurgical work, slag, crushed green job sector projects. Specification determines the quality of the products, the company has a variety of impact crusher can be customized according to customer demand.

High-speed railway and highway construction sand and gravel aggregate concrete particle shape arrangement, a high level of demand, especially basalt (diabase) flakiness content of rubble, while the former simple cone crusher, impact crusher process has can not meet demand, SBM launched satisfy the technical requirements for vertical shaft crushers and plastic-based new crushing and screening process of impact; efficient vertical shaft impact crusher is the production of high-performance concrete (C40 and above) are equipment required aggregate (gravel) and quality of stone, bone through the machine (stones) does not exceed 5% of the material sheet, can fully meet the production of these professionals work in high performance concrete (C40 ~ C80) aggregate technical requirements.
