In the fast-developing road and real estate sector of Rajasthan, Sai Puja Stone Crusher, led by Mr. Leeladhar Choudhary, is a trusted supplier of aggregates to contractors and RMC plants. To strengthen their production process and meet the growing demand for well-graded, cubical aggregates, the company invested in a Taurian secondary station equipped with the CG250 Cone Crusher and CMS2060 Vibrating Screen—a powerful combination for precision shaping and accurate gradation.

Geological Setting – Hard Quartzite & Granite of Ajeetgarh

Ajeetgarh’s geology is dominated by dense quartzite and granite, known for their durability but also for their abrasiveness. These materials require crushers with high crushing force and screening systems that can maintain efficiency under heavy load, ensuring uniform particle size for bitumen, concrete, and sub-base applications.

The Challenge

Before the upgrade, Sai Puja Stone Crusher’s secondary stage faced:

  • Poor shape control leading to flaky aggregates.
  • Inconsistent gradation, resulting in rejections from RMC plants.
  • High recirculation loads due to inaccurate screening.
  • Frequent downtime for maintenance and liner changes.

Mr. Choudhary needed a reliable setup that could handle high volumes of hard rock while delivering superior shape and precise sizing every shift.

The Solution

Taurian Secondary Station comprising:

  • CG250 Cone Crusher – Heavy-duty bearing design for maximum crushing force, hydraulic CSS adjustment for quick setting changes, and a chamber profile optimized for cubical output.
  • CMS2060 3/4-Deck Screen – High-capacity screening with sharp separation cuts, ensuring multiple clean product sizes in a single pass.

Key Features:

  • Improved Shape Quality: Reduced flakiness and elongation index in output.
  • Efficient Gradation Control: Multiple deck screening enables production of well-graded aggregates.
  • Low Maintenance Downtime: Wear parts engineered for long life in abrasive rock conditions.
  • Optimized Throughput: Reduced recirculation improves plant efficiency and lowers operating costs.

Results & Impact

Following installation, Sai Puja Stone Crusher achieved a 35% increase in consistent, saleable output, with high-quality aggregates in 20mm, 10mm, and 6mm sizes meeting MORTH standards. Customer satisfaction improved, and the plant’s enhanced efficiency allowed Mr. Choudhary to secure larger contracts in both road and building projects.

Key benefits included:

  • Zero rejections from quality-conscious clients.
  • Lower operating cost per ton due to reduced wear and energy efficiency.
  • Faster order fulfillment, increasing market competitiveness.
