subject: The Vertical Shaft Impact Crusher Is One New Type Of Impact Crusher [print this page] In this article, we will tell some details about impact crusher,such as impact crusher concept,impact crusher working principle,one new type of impact crusher-verticle shaft impact crusher, and impact crusher application.First, what is an impact crusher? The so-calledimpact crusher is the objects in the free state by the striking force along its natural fissures, the weak part of the bedding plane, joint surface, such as selective crushing broken. It is different from hammering broken objects by the striking force in the constrained state, but also with other shear, economic pressure, grinding broken and different, and thus the lowest energy consumption in the crushing process, and due to its selective crushing capacity from the separation of useful minerals and more cubic role to monomer.Second, the working principle of impact crusher is high-speed transfer of hammerhead gives the crushing chamber materials for high-speed impact, the material occurrence of impact crusher, and the impact of material high speed toward the back plate, the material being again after the impact crusher from the back plate bounced back the hammer to combat repeat the crushing process, the material in the round-trip between the hammer and the back plate, between them there are still collision shock. When the broken particle size less than the gap between the hammer and the back plate, and discharged from the lower part of the machine is broken products. The fragmentation energy for different grain size materials are different, the more small material due to internal defects to gradually reduce its crushing energy required is greater.Third, the vertical shaft impact crusher is one new type of impact crusher, it is also called as sand making machine. And VSI crusher is the representative of the material crushing aspects of the impact crusher. We know that the wear of the hammer is to improve the non-linear growth and the speed of the hammer rotary line, when the crushing hammer of the high line speed, and relatively lesser quality materials can not enter the high-speed rotary hammer to effectively combat zone (happens to be at a maximum line speed range), resulting in broken down effect and hammer wear increased. The center of vertical shaft impact crusher used feed materials into the starting speed close to zero, away to gradually accelerate the projectile from the rotor body impact crusher to improve the impact of the crushing effect and reduce the wear of the consumable parts . This crusher evolution of mechanical and lining two categories.Last but not least, the impact crusher features heavy duty rotor design, unique hammer locking system, interchangeable wearing parts, and easy maintenance.And it is extensively used in many industries, especially in highway, construction, water project, asphalt or slag recycling.It can crusher hard, soft, abrasive, metal and non-metal materials such as copper, iron, manganese, coal, quartz, feldspar, calcite, talc etc.In a word, impact crusher is an important crusher machines used in mining industry. It can used for various ore crushing, so it is very important to select suitable impact crusher based on the raw materials.
