PI-2 Mobile Limestone Crushing Plant 250-300 TPH

The CONSTMACH PI-2 represents a breakthrough in mobile crushing technology, specifically engineered for processing limestone and other materials with low to medium hardness levels. This mobile crushing plant delivers exceptional performance in quarries and construction sites where efficiency and mobility are paramount. With a production capacity ranging from 250 to 300 tons per hour, the PI-2 stands out as a reliable solution for contractors and operators who demand consistent output without compromising on product quality.

What sets this mobile crusher apart is its integrated design philosophy. The plant combines a robust primary impact crusher with an advanced screening system, all mounted on a single wheeled chassis. This configuration eliminates the complexity of managing multiple machines and reduces operational costs significantly. The CPI-1415 primary impact crusher forms the heart of the system, capable of handling feed material up to 950 x 950 mm in size. The feeding hopper features a vibrating feeder that ensures steady material flow, while the by-pass conveyor intelligently removes soil and fine particles before they reach the crushing chamber. This pre-screening capability extends the life of wear parts and maintains optimal crushing efficiency throughout operation.

The screening section utilizes a high-capacity vibrating screen available in either three or four deck configurations, allowing operators to produce multiple product sizes simultaneously. This flexibility is crucial for projects requiring different aggregate fractions for various applications. The feedback conveyor creates a closed-circuit system by returning oversized material from the screen back to the impact crusher, ensuring maximum size reduction and superior particle shape. The result is consistently cubical aggregates that meet stringent specifications for concrete production and asphalt manufacturing.

Transport and setup logistics often present significant challenges for mobile crushing operations. CONSTMACH addressed this by designing the PI-2 within international road transport dimensions of 20 meters length, 3.85 meters width, and 4.5 meters height. Despite weighing 55,000 kg, the plant moves effortlessly between job sites on its wheeled chassis. The hydraulic leg system provides stable support during operation and retracts for transport. For maximum convenience, operators can opt for hydraulic opening mechanisms on the feeding hopper and stockpile conveyors, enabling complete setup without external equipment like cranes or loaders. This feature dramatically reduces mobilization time and eliminates dependency on additional machinery.

The automation system deserves special attention. Rather than relying on traditional control panels, the PI-2 mobile crushing plant employs premium SIEMENS and SCHNEIDER electronic components integrated with a PLC-based control system. Operators manage the entire plant through a tablet controller, providing unprecedented ease of use and real-time monitoring capabilities. This modern approach to automation reduces the learning curve for new operators while giving experienced personnel precise control over every aspect of the crushing process. The dust removal system works seamlessly with the automation package to maintain a clean working environment and comply with environmental regulations.

Power requirements are straightforward with a total motor power of 400 kW. The plant typically connects to site electrical infrastructure requiring 1,100 kVA capacity. However, recognizing that not all job sites have reliable power access, CONSTMACH offers an optional diesel-electric generator set that can be integrated directly onto the chassis. This option transforms the PI-2 into a completely autonomous unit capable of operating in remote locations without external power sources.

The feeding height of 4.5 meters provides adequate clearance for loading equipment to work efficiently without restriction. The fold-up stockpile conveyors discharge finished products at appropriate heights for direct truck loading or stockpile building. This thoughtful design consideration minimizes material handling requirements and keeps the overall operation streamlined. The mobile crusher's compact footprint doesn't sacrifice functionality, making it suitable for confined spaces where larger stationary plants cannot operate.

Material characteristics play a crucial role in crusher performance. The PI-2 excels with limestone, which constitutes a large portion of aggregate production worldwide. The impact crushing principle employed by the CPI-1415 generates superior particle shape compared to compression-style crushers, producing the cubical aggregates that command premium prices in the marketplace. The fine material ratio in the final product meets market demands without requiring additional processing steps.

For operations prioritizing flexibility, rapid deployment, and consistent product quality, the PI-2 mobile limestone crushing plant delivers measurable advantages. Its combination of proven crushing technology, intelligent automation, and mobility features makes it a practical investment for both established quarry operators and contractors entering the aggregate production business. The plant's ability to start producing revenue-generating material within hours of arrival at a new site translates directly to improved project economics and faster return on investment.
