What kind of machinery is good for crushing granite or limestone?

For crushing granite or limestone, you would typically use a jaw crusher as the primary crushing machine. This is because jaw crushers can handle large blocks of rocks and can crush them into smaller pieces with ease. Additionally, jaw crushers are capable of producing a consistent, uniform size of product.

Cone crushers and impact crushers are also often used for secondary and tertiary crushing, especially when the output size needs to be smaller than that produced by a jaw crusher. These machines work by using high speed impact or compression to crush the rocks.

It’s important to choose the right type of machinery for your specific application, as well as considering factors such as the hardness of the rock, the desired final product size, and the production capacity required. You may also need to consider additional equipment such as vibrating screens and feeders, depending on the specifics of your operation.
