The Challenge

The customer needed a high-capacity quartzite crushing and sand-making production line capable of processing blasted quartzite into multiple finished aggregate sizes. Quartzite is a hard stone material, so the production process required strong feeding, reliable primary crushing, efficient medium-fine crushing, accurate screening, and stable sand-making performance. The main challenge was to convert large blasted quartzite into well-graded aggregates and manufactured sand while maintaining production stability and reducing unnecessary material return. The customer also needed a line that could produce different finished sizes for construction aggregate, road materials, concrete production, and infrastructure applications.

600 T/H quartzite crushing capacity
Complete crushing and sand-making process
Produces 0–5mm to 10–30mm aggregates
Stable screening and finished product grading

Our Solution

Zhenggang Machinery designed a complete quartzite crushing and sand-making process based on the customer’s raw material and finished product requirements. Blasted quartzite is first conveyed evenly by the GZD-1300×3600 vibrating feeder into the PE-1200×1500 jaw crusher for primary crushing. The material is then transported by belt conveyor to the PF1820 impact crusher for medium and fine crushing. After two-stage crushing, the material enters the 4YK1848 vibrating screen for classification. Screened material is sent to regulating silos and then conveyed to the TK8622 sand-making machine for efficient fine crushing and sand production.

Equipment Provided

Implementation Timeline

Site Assessment

2 weeks

Quartzite hardness, blasted material size, quarry layout, and finished aggregate requirements

Equipment Design

3 weeks

Quartzite crushing, screening, regulating silo, conveying, and sand-making process design

Installation

5 weeks

Feeder, jaw crusher, impact crusher, vibrating screen, silo, conveyor, and sand maker installation

Training

1 week

Operator training for crusher adjustment, screening control, sand-making operation, and maintenance

The project was implemented through quarry site assessment, quartzite material analysis, process design, equipment selection, installation, commissioning, and operator training. Zhenggang Machinery configured the production line to support primary crushing, medium-fine crushing, screening, material regulation, and final sand making. This structured process helped the customer achieve stable high-capacity quartzite aggregate production and consistent finished material grading.

The Results

After commissioning, the 600 T/H quartzite crushing and sand-making production line achieved stable high-capacity operation and reliable finished product grading. The production process allowed the customer to produce multiple aggregate sizes, including 0–5mm, 5–10mm, 10–20mm, and 10–30mm. The combination of jaw crushing, impact crushing, screening, regulating silo feeding, and TK8622 sand making improved quartzite processing efficiency and supported high-quality construction aggregate and manufactured sand production for quarry, concrete, road, and infrastructure projects.
