Typical Configuration Of A 300 Tph Sand Making Plant

A 300 tph sand making plant is engineered to process raw materials like granite, limestone, river pebbles, or basalt into high-quality construction sand efficiently. Its configuration is tailored to balance crushing, shaping, screening, and handling, ensuring consistent output and sand quality. when integrated with sand washing and dewatering systems, ensures high-purity, low-moisture sand—critical for premium concrete, asphalt, and construction applications. Below is the typical equipment setup and key stages:

1. Raw Material Feeding System

- Vibrating Feeder (e.g., GZD 1300×4900): Uniformly feeds raw materials (up to 500mm) from the storage hopper to the primary crusher, with adjustable vibration to prevent overload.
- Storage Hopper: Acts as a buffer for continuous feeding, even with intermittent material delivery.

2. Primary Crushing Stage

- Jaw Crusher (e.g., PE 900×1200 or C125): Reduces large boulders to 50–150mm particles, ideal for hard/abrasive materials like granite, protecting downstream equipment.

3. Secondary Crushing Stage

- Cone Crusher (e.g., CH440 or CS 250): Further crushes 50–150mm material to 10–30mm for uniformity. For softer materials (e.g., limestone), replace with an Impact Crusher (e.g., PF 1315) to enhance particle shape.

4. Sand Making (Final Shaping) Stage

- Vertical Shaft Impact (VSI) Crusher (e.g., VSI 6X 1263 or VSI 5X 1145): Converts 10–30mm particles into cubical sand (0–5mm, 5–10mm, 10–20mm) via high-speed rotor impact. Adjustable settings control fineness and reduce flakiness.

5. Screening, Washing, and Classification System

- Vibrating Screen (e.g., 3YK 2460): Separates crushed material into graded sand. Oversized particles (>20mm) are recycled back to the VSI crusher for reprocessing.
- Sand Washing Machine (e.g., XSD 3016 or LSX 920): Cleans the graded sand by removing dust, clay, and impurities. It uses water to scrub particles, ensuring sand purity (impurity content <1%).
- Dewatering Screen (e.g., TS 1836): Reduces moisture in washed sand from ~20% to 8–12% by vibrating and draining excess water. This ensures the sand is ready for immediate use or storage without caking.

6. Conveying and Storage System

- Belt Conveyors: Transport materials between stages (feeding → crushers → VSI → screen → washing → dewatering). Widths range from 800mm to 1200mm, with speed adjustments to match production flow.
- Silos or Stockpiles: Store dewatered sand by grade. Optional automated stacking systems organize inventory for easy loading.

7. Water Recycling System (Optional but Recommended)

- Sedimentation Tank + Filter Press: Collects wastewater from washing and dewatering, treats it to remove sludge, and recycles clean water back to the sand washing machine. Reduces water consumption by 60–80% and meets environmental standards.

8. Control System

- PLC Control Panel: Monitors real-time data (output, power, equipment status) and automates adjustments (e.g., feeder speed, crusher settings). Integrates washing/dewatering parameters to optimize water usage and moisture levels.

This configuration ensures the 300 tph line produces clean, low-moisture sand with consistent gradation, meeting strict quality standards for high-end construction projects. The addition of washing and dewatering eliminates impurities and excess water, enhancing sand value and usability.
