We often use limestone crushers to crush bulky limestone rocks to smaller crushed limestone!

Popular limestone crushers are hammer crushers, impact crushers, jaw crushers, and mobile crushers.

When crushing[b] limestone with a mud content of less than 5% and a moisture content of less than 7%[/b], choose a hammer crusher.
Hammer crushers are the first choice for crushing soft to medium-hard rocks. Moreover, with small crushing cavity and well-sealed structure, hammer crushers solve the problems of dust pollution and powder leakage.
Limestone that contains too much mud and water can cause the material to build up on the grates of the hammer crusher, resulting in severe blockage.

When crushing[b] limestone with a moisture content exceeds 7%[/b], impact crusher is a good choice.
The impact crusher has more advantages in processing materials with high water content. The feed chute and impact plate of the impact crusher can be equipped with a heating device to prevent the material from sticking. And it has no grate sieve plate at the bottom, avoiding blockage.

When the[b] limestone rock is highly abrasive[/b], choose an impact crusher. It has a better adaptability to abrasive rocks than other stone crushers. When the abrasiveness is high, you'd better adopt a two-stage crushing process. The common collocation is jaw crusher as primary crusher and impact crusher as secondary crusher.
