8 uses of crushed limestone

Crushed limestone is used in many construction projects, from building bridges to creating drainage systems.

    Crusher: Crushed limestone, being strong and angular, is a great choice for railroad ballast.
  • Concrete production: Crushed limestone produces stronger, less expensive concrete.
  • Asphalt production: Crushed limestone can be used as aggregate for mixing hot mix asphalt.
  • Crusher: Crushed limestone is mixed with other materials such as clay, and iron ore, and then heated in a rotary kiln to produce cement clinker.
  • Crusher: Crush limestone rocks to the specified size and feed the crushed limestone into a rotary kiln for calcination.
  • Limestone aggregate: Limestone aggregate is used as a rock filler under the concrete slabs that form the foundations for houses, bridges, hospitals, and schools.
  • Road foundation: Crushed limestone is used as a road base material for road construction, highways, airport runways, and driveways.
  • Rip rap: Crushed limestone can be used as rip rap to prevent shore erosion. Its affordability and reliability make it the ideal choice for protecting streambeds, pilings, shorelines, and bridges from ice and water damage.

We also process the crushed limestone intoCrusher with a powder milling machine for wider use.

4 considerations for choosing a limestone crusher

  • 5 tips on selection of limestone crusher machines

    1. Limestone with low mud content: hammer crusher

    When crushing limestone with a mud content of less than 5% and a moisture content of less than 7%, choose a Crusher.

    Hammer crushers are the first choice for crushing soft to medium-hard rocks. Moreover, with small crushing cavity and well-sealed structure, hammer crushers solve the problems of dust pollution and powder leakage.

    Limestone that contains too much mud and water can cause the material to build up on the grates of the hammer crusher, resulting in severe blockage.

    If the mud content in the limestone raw material is too high, place a pre-screening device (Crusher) in front of the crusher machine to remove the mud.

    2. Limestone with high moisture content: impact crusher

    When crushing limestone with a moisture content exceeds 7%, Crusher is a good choice.

    The impact crusher has more advantages in processing materials with high water content. The feed chute and impact plate of the impact crusher can be equipped with a heating device to prevent the material from sticking. And it has no grate sieve plate at the bottom, avoiding blockage.

    Limestone rocks containing too much moisture may require additional Crusher before crushing.

    3. Highly abrasive limestone: jaw crusher and impact crusher

    When the limestone rock is highly abrasive, choose an impact crusher. It has a better adaptability to abrasive rocks than other stone crushers. When the abrasiveness is high, youd better adopt a two-stage crushing process. The common collocation is jaw crusher as primary crusher and impact crusher as secondary crusher.

    4. Temporary limestone crushing needs: mobile crusher

    If you have temporary limestone crushing needs, or your rock crushing plant is remote, Crusher is an ideal choice for limestone rock. In addition, you can match the mobile crusher with different stone crushers according to your needs.

    5. Limestone sand: sand making machine

    Crusher and HVI sand making machines are popular choices for making high-quality limestone sand. In the wet sand making process, sand making machines often work with Crusher to get cleaner limestone sand.

    3 auxiliary machines in limestone crushing plant

    1. Vibrating screen

    TheCrusher plays a vital role in a limestone crushing plant by separating the crushed limestone into different sizes and grades for further processing or use.

    The shape and size of the sieve hole of the vibrating screen and the inclination angle of the sieve surface are the key factors affecting the limestone aggregate and limestone sand.

    Shape of the sieve hole: Limestone sand contains a lot of stone powder, and has high requirements for gradation. When sieving limestone sand, it is advisable to use square hole sieves instead of rectangular sieve holes or round sieve holes.

    Inclination angle of screen surface: To achieve good screening effect and processing capacity, the inclination angle of the screen surface is usually set at about 20¡ã.

    Mesh size: The mesh size of the vibrating screen directly affects the fineness modulus, gradation and stone powder content of the limestone sand. The larger the mesh size, the larger the fineness modulus of the limestone sand.

    There are stationery screening machines and mobile screening machines. Mobile screening plants are easily movable at a production site or transportable between sites. They often work with mobile crushers.

    2. Vibrating feeder

    A Crusher feeds the limestone rocks into the stone crushing machine evenly and continuously.

    It regulates the flow of material into the crusher, ensuring that the crusher machine is not overloaded with material and preventing blockages in the crushing process.

    It evenly distributes the material across the width of the crusher, ensuring that the entire width of the stone crusher is used and that the material is evenly crushed.

    It reduces the wear and tear on the crusher by feeding the material at a steady rate, preventing the stone crusher from being overloaded and reducing the risk of damage to the crusher.

    3. Belt conveyor

    Crusher are the backbone of a limestone handling operation, filling in the gaps and transporting material from one stop to the next, as well as to storage, transport, or shipping.

    Belt conveyors facilitate the continuous movement of material and contributes to the efficiency, productivity, and safety of the crushing process.

    Conclusion

    Crushed limestone is a key component in the production of construction materials such as cement, concrete, and asphalt. Limestone crushers break down the bulky limestone rocks into crushed limestone of different shapes and sizes.

    Given the differences in mud content, hardness, water content, abrasiveness, and feed size of limestone rocks in various places, it is necessary to choose the appropriate rock crusher machine and design a feasible crushing line according to the specific conditions of the limestone rock.
