Choosing the right primary crusher for limestone crushing

Overview Of Limestone And Its Uses

Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3), typically in the form of calcite or aragonite. Limestone's versatility and abundance make it a valuable resource in various industries and applications, from construction and agriculture to environmental remediation and art. Limestone aggregates are used in concrete and asphalt, dimension stone for building facades and countertops.

Primary Limestone Crusher

Primary crushers reduce large limestone material, such as rocks and ore lumps, into smaller sizes for further processing downstream, whether that be transport to additional crushers or to a wet processing plant. The two main factors to consider when identifying purpose are feed size and type of material to be crushed. There are three types of primary crushers

Gyratory crusher is usually used only when the target production exceeds one million tons per year. Normally it has long manufacturing time and onsite installation time too. This makes users best suited for factories with long-term plans. They are ideal for abrasive materials crushing such as granite.

Jaw crusher is the main crusher and the most commonly used primary crusher. Jaw Crushers are a compression-type machine that crush material between a moving piece of steel and a stationary piece of steel. It is suitable for all rock materials. What’s more, it could be fixed type or mobile type.

Impact crusher is best suited for less abrasive materials such as limestone. Limestone in impact crusher is constantly colliding within the crusher at high velocities to break the rock apart. The impact crusher incurs higher wear costs over time, but can generally provide greater crushing results and better shape. 

People Also Frequently Asked For- FAQ

1. Is limestone easy to crush?

Limestone is an easy to crush sedimentary rock that is a soft to medium-hard. Crushed limestone has a variety of uses from dense graded aggregates (DGA) to aggregates for concrete and asphalt materials.

2.What happens when crushed limestone gets wet?

It is known as one of the densest, but the problem is that water changes everything for this stone. It has the power to dissolve carbonate, and the softening would happen. Fortunately, when completely dry, the hardness will come back again.

3.How to crush limestone?

The first step in crushing limestone is primary crushing. This is usually done using a jaw crusher, which breaks the larger rocks into smaller pieces. Jaw crushers have a fixed jaw and a moving jaw. The moving jaw exerts force on the rock to crush it against the fixed jaw.
