Lime Production 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. . Compression crushers are used mainly for larger

Oxygen-enhanced cement and lime production tell me more

Increased production rates Most cement and lime plants that are fan-limited implement oxygen enrichment to increase production. The added oxygen enables the combustion of additional fuel, allowing operators to increase feed rates. Enhanced kiln stability and quick recoveries from “pushes” also translate into increased production.
