Lime Production: Industry Profile

Lime Production: Industry Profile

Crushing The first step in the manufacturing of lime is to crush the pieces of limestone to make them smaller. There are two basic types of primary crushers: compression and impact. Compression crushers use slow, steady amounts of pressure to reduce the size of the rock, whereas impact crushers rely on intense, repeated blows.

How Does Limestone Affect the Environment?

How Does Limestone Affect the Environment?

 · Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn't hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.
