How impact crusher works Want to Know How Does Impact Crusher Work? The impact crusher is a machine which works with shock principle the materials in the crushing chamber suffer a high speed crush from the high-speed rotating hammer the crushed materials rush over to the impact plate and coming back again this process will repeat until the products satisfied the requirements i e the
The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers* It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size

The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi) also known as the Impact Work Index The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers The open and closed sized settings for given product sizes can also be determined
The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers* It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size P80 = 25400 x Oss x (0
The Bond crushing work index test (sometimes called the impact work index test) is noisy and the difference you observed is perfectly reasonable The paper by Angove Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4 5
