Limestone Quarry Extraction Equipment

Most limestone are extracted by open pit quarrying method. Surface mining equipment varies with the kind of stone mined, the production capacity needed, the size and shape of the deposit, estimated life of the operation, location of the deposit with respect to urban centers, and other important factors.

Typically, drilling is done with tricone rotary drills, long-hole percussion drills, and churn drills. Blasting in smaller operations may be done with dynamite, but in most medium-to large-size operations. The rock is then extracted using power shovels or bulldozers.

Underground Limestone Mining Equipment

Underground operations are becoming more common for limestone mining, as miners increasingly recognize the benefits of such operations. By underground application, a variety of problems usually connected with surface mining, such as environmental impacts and community acceptance, are significantly reduced.

Underground room-and-pillar mines can be operated on a year-round basis and do not require extensive removal of overburden, producing a minimum of environmental disturbance.

Limestone Quarry Extraction Equipment

Limestone quarry extraction processing activities include conveying, screening, secondary and tertiary crushing, and sizing. Screening is the single most important part of the processing cycle of crushed stone particles.

A wide variety of screen types exist, such as Inclined vibratory screens and horizontal screens, and their selection is a function of the material processed and the final product required. It can be in stationary types and portable screening plant.
