200tph Limestone/Weathered Stone Mobile Impact Crusher Plant Share

At a mine site in Saudi Arabia, we provided a customized mobile crushing solution for processing a mixture of limestone and weathered rock. This solution utilizes a mobile impact crushing plantcombining a ZSW4200x1100 vibrating feeder and a PF1315 impact crusher, achieving a stable output of 200 t/h with precise control of the finished product size to 0-80mm, meeting high-standard production requirements.

Raw Material Characteristics and Crushing Challenges

• Limestone: Medium-hard rock, compressive strength ≤150MPa

• Weathered rock: Brittle, high clay content, unstable composition

Core Challenges:

• High production capacity requirements: Continuously and stably achieving 200 tons/hour, avoiding material blockage and downtime

• Raw material compatibility: The same equipment needs to adapt to materials with significantly different hardness levels

• Environmental requirements: Complying with strict local dust emission standards in Saudi Arabia

Process Flow

At the crushing production site in Saudi Arabia, the entire process achieves a four-stage efficient closed-loop treatment: First, the ZSW4200×1100 vibrating feeder provides uniform and controllable feeding of raw materials, ensuring stable input; then the material enters the PF1315 impact crusher, whose adjustable rotor speed intelligently adapts to the hardness of limestone and the brittleness of weathered rock, achieving efficient fine crushing; the crushed material is then precisely classified by a vibrating screen, quickly separating the qualified 0-80mm finished product and large-particle return material; finally, multiple belt conveyors classify and output different specifications of finished aggregates, completing the entire continuous production process from raw materials to high-quality sand and gravel products.
