Compact Crushing & Screening Plants for Small-Scale Sand Production

For entrepreneurs seeking self-employment opportunities in construction materials, small-scale crushing and screening equipment offers a low-investment, high-efficiency solution. These compact plants process natural stone or recycled concrete into high-quality sand and aggregates for local markets.

Core Equipment Specifications

A typical mini sand production line includes:
1. Jaw Crusher (PE-250×400)
– Feed size: ≤210mm
– Capacity: 5-20t/h
– Power: 15kW
2. Impact Crusher (PF-1007)
– Output size: 0-30mm adjustable
– Capacity: 10-30t/h
3. Vibrating Screen (2YK1235)
– Screening layers: 2
– Processing capacity: 8-50t/h

Production Line Configuration

A basic setup processes raw material through primary crushing → secondary shaping → screening → sand washing (optional). The entire line occupies only 50-100㎡ and can be mounted on trailers for mobile operation.

FAQ

Q1: What’s the minimum investment?

Case Study: Urban Recycling Project

A contractor in Texas processes demolished concrete with a mobile plant (30t/h capacity), producing ASTM C33-compliant aggregates sold to local ready-mix plants at $12/ton. The operation breaks even within 8 months.
