Commonly used in sand and gravel crushing production line equipment jaw crusher, impact crusher, crushing machine, crusher, hammer crusher. Different devices, different effects on the crushing of materials, this paper describes the production line in the sand and gravel impact crusher performance advantages.

    Impact crusher and the crusher-based compression, such as jaw, cone and roll crusher and other than have the following characteristics:

    1. Crushing ratio

    Impact crusher can reach the crushing ratio of 50 or more, while the jaw crusher, cone crusher and roll crusher is difficult to over 20.

    2. A good product particles

    Under the impact, often by breaking down the material level of fragmentation of its most vulnerable, such selective fragmentation method, the particles form a cube a high probability of drought, so the impact crusher product content can be lower than the percentage flakiness 10%, while the jaw, cone and roll crusher products such as the percentage flakiness level is higher than 15%. These characteristics make the impact crusher in numerous plays an important role in crushing machinery.

    Impact crusher crushing machine is compared to other great advantages, but the impact crusher in the objective existence of defects. The impact crusher is broken by the impact of the principle of materials, their combat items, such as: hammer, hammer boards, counter boards, wear and tear in use very quickly. This defect, in the very long period of time, limit the application of impact crusher range. Can only be used for crushing of hard materials.
