Palanpur has become a key supplier of construction aggregates for infrastructure projects across Gujarat and neighboring states. Among the region’s most trusted names is Shakti Quarry Works, led by Mr. Haji, who has built a strong reputation for delivering high-quality aggregates to ready-mix plants, highway contractors, and metro rail projects. With increasing demand for cubical and consistent M-Sand and P-Sand, Mr. Haji sought a solution that would enhance product quality and throughput without significantly increasing operational complexity.

Geological Setting – Aggregate Resources of Palanpur

Palanpur sits atop a region dominated by medium- to high-density basalt and granite formations—ideal for aggregate production but challenging in terms of hardness and shape generation. The presence of fractured rock zones and dust-prone crushing processes further called for a machine that could deliver both shape improvement and dust control.

The Challenge

Shakti Quarry Works was operating with conventional cone and jaw crushing setups, which produced aggregates in bulk but struggled to meet modern standards for shape and grading. Increasing rejection rates from RMC plants due to flaky particles and inconsistent fines created bottlenecks in dispatch and impacted customer satisfaction. Mr. Haji needed a dedicated tertiary solution that could enhance the final product shape, reduce the flaky index, and improve the quality of plaster sand.

The Solution

Taurian’s T-110 VSI Crusher

After site evaluation and material testing, Taurian recommended its T110 Vertical Shaft Impactor (VSI)—a compact yet powerful tertiary crusher designed for shape correction, sand manufacturing, and consistent fine output.

Key Features:

  • Rock-on-Rock Crushing Principle: Delivers excellent particle shape with minimal generation of elongated or flaky particles.

  • Low Power Consumption: Optimized rotor design ensures lower operating costs per ton.

  • Ease of Maintenance: Quick-access rotor chamber and wear part replacement features reduce maintenance downtime significantly.

Results and Impact

Post installation of the T110 VSI, Shakti Quarry Works achieved a 30% improvement in final product shape and a drastic reduction in flaky particles—bringing rejection rates from RMC clients down to near-zero. The VSI also enabled production of high-grade plaster sand, opening up a new revenue stream and improving margins. Additionally, overall plant efficiency increased as the load on secondary crushers was reduced.

Within months, Mr. Haji’s operation became a preferred supplier to high-spec projects in the Ahmedabad-Gandhinagar industrial corridor and Smart City initiatives, owing to the superior shape and cleanliness of their aggregates.
