Flow Sheet for a 200 TPH Sand Plant and Comprehensive Guide to Crushing & Screening
The global demand for high-quality sand and aggregates continues to rise, driven by infrastructure development, urbanization, and construction projects. Manufactured sand (M-Sand), produced through crushing and screening processes, has become a sustainable alternative to natural river sand due to environmental regulations and scarcity. A well-designed 200 TPH (tons per hour) sand plant ensures efficiency, product consistency, and compliance with industry standards.

A typical flow sheet for a 200 TPH sand plant integrates primary crushing, secondary/tertiary crushing, screening, sand washing, and material handling. Below is a breakdown of the key stages:
1. Primary Crushing
– Equipment: Jaw crusher or gyratory crusher.
– Function: Reduces raw feed (e.g., granite, basalt) to ≤150mm.
– Output: Coarse aggregate for further processing.
2. Secondary/Tertiary Crushing
– Equipment: Cone crusher or impact crusher.
– Function: Further reduces material to ≤40mm for sand production.
3. Screening
– Equipment: Vibrating screens (multi-deck).
– Function: Separates aggregates into desired sizes (e.g., 0-5mm for sand, 5-20mm for concrete).
4. Sand Making
– Equipment: Vertical shaft impactor (VSI) or high-speed cone crusher.
– Function: Shapes crushed material into cubical sand particles.
5. Sand Washing & Dewatering
– Equipment: Wheel bucket washer or hydrocyclone + dewatering screen.
– Function: Removes silt/clay and controls moisture content (<5%).
6. Material Handling
– Conveyors, bins, and dust suppression systems ensure seamless operation.

1. Feed Material Hardness: Dictates crusher selection (e.g., VSI for abrasive rock).
2. Moisture Content: Affects screening efficiency; may require pre-screening.
3. Environmental Compliance: Dust collectors and water recycling systems are critical.

Q1: What’s the typical power consumption for a 200 TPH plant?
A: ~500–600 kW, depending on rock hardness and equipment configuration.
Q2: How to minimize over-crushing fines?
A: Optimize crusher settings (e.g., CSS in cone crushers) and use multi-stage screening.
Q3: Can limestone be used for M-Sand?A: Yes, but it may require additional washing due to higher clay content.
