PF Series Limestone Crusher Manufactured by DSMAC Introduction
Limestone is a sedimentary rock composed largely of calcite, calcium carbonate (CaCO3). Limestone often contains variable amounts of silica or siliceous skeletal fragment, as well as varying amounts of clay, silt and sand sized terrestrial detritus carried in by rivers.

In construction, crushed limestone is used as an aggregate in concrete mixes. The limestone binds the mix together when it hardens. Almost 60% of all crushed limestone is used as aggregate in highway concrete and asphalt. All crushed limestone in Michigan is mined in open quarries. Drilling and blasting are necessary.

The proposed limestone crusher is DSMAC impact crusher, which features reasonable structure, high productivity, easy operation and maintenance and safe performance. It can crush the material whose pressure resistance strength is under 350Mpa. The limestone from the mines is conveyed to the crusher through conveyor. Crusher reduces the size of the limestone from 1m to –25 mm size. The crushed limestone will be sent by a belt conveyer to vibrating screen becoming final products or to grinding mill to fine grind. In order to control the emissions from the crusher, a suitable bag filter system will be provided.

Main Customer Benefits of DSMAC Impact Crusher are:
1. Crushing is conducted with multiple crushing cavities. The impact crusher is particularly suitable for hard rock crushing.
2. The rotor is designed with the most advanced finite-element analysis technology for local reinforcement.
3. The high-chromium blow bar is manufactured with crystal alloy which results in its sound impact resistance and wear resistance.
4. The space between impact plate and plate hammer is convenient to adjust. The finished product is cubic-shaped.
5. Designed with a hydraulic opening device, easy and convenient to operate, install and maintain.
6. The new wear resistant materials enable the blow bar, impact plate and liner plate to have a longer service life.
