Limestone And Gypsum Mobile Stone Crusher Plant Mini Mobile Stone Crusher

Mobile crusher for limestone and gypsum with low wear rate

1.Product Introduction Portable Stone Crusher

The Mobile Crusher for Limestone and Gypsum is an optimized processing plant designed specifically for soft to medium-hard sedimentary rocks. While limestone and gypsum are less abrasive than granite, they often present challenges such as high dust levels or moisture-driven stickiness. This unit features a high-speed Impact Crusher or a Heavy-Duty Hammer Mill configuration, which utilizes "rock-on-rock" and "strike-and-shatter" principles to achieve high reduction ratios with minimal component wear. By matching the metallurgy of the blow bars to the specific Mohs hardness of limestone, this machine delivers an exceptionally low cost-per-ton and a superior cubical product shape.

2.Application Portable Stone Crusher

• Cement Production: Primary and secondary crushing of limestone and shale feedstock for cement kilns.

• Gypsum Board Manufacturing: Reduction of natural gypsum rock for industrial wallboard and plaster production.

• Agricultural Lime: Crushing limestone into fine aggregates for soil pH adjustment and fertilizer fillers.

• Flue Gas Desulfurization (FGD): Producing high-purity limestone powder for environmental scrubbing in power plants.

3.Working Principle Portable Stone Crusher

• Impact Shattering: Material enters the crushing chamber and is struck by high-velocity blow bars attached to a heavy-duty rotor. The limestone is hurled against apron plates, shattering along natural cleavage planes.

• Low-Friction Design: Unlike jaw crushers that rely on high-pressure compression (which can cause "smearing" with soft rock), the impact method uses kinetic energy, which reduces the contact time between the rock and the wear parts.

• Adjustable Gradation: The gap between the rotor and the impact aprons is hydraulically controlled, allowing for precise adjustment of the output size. This ensures that the material is not "over-crushed" into wasted fines.

• Gravity-Assisted Discharge: The internal chamber is designed with a steep angle to prevent "bridging" or buildup, even when processing gypsum with higher-than-average moisture content.

4.Advantages Portable Stone Crusher

• Optimized Wear Life: Specifically selected Martensitic or Ceramic-insert blow bars provide up to 40% longer life when processing non-abrasive limestone compared to standard manganese steel.

• Exceptional Cubical Shape: The impact crushing process naturally produces a high-quality cubical product with minimal slivers, which is ideal for high-strength concrete and road base.

• High Reduction Ratio: Capable of taking large feed sizes and reducing them to a finished product in fewer stages, often eliminating the need for a secondary crusher.

• Integrated Dust Suppression: Equipped with high-pressure water misting systems at the feed and discharge points to manage the high dust levels typically associated with dry limestone.

• Fuel-Efficient Drive: Optimized rotor inertia allows the engine to run at a lower RPM while maintaining the necessary crushing torque, reducing fuel consumption by up to 15%.
