Iron ore scrubbing is a critical step in mineral processing, removing clay, dirt, and impurities from raw ore. A well-designed crushing and sand-making line ensures high efficiency and product quality. Below is a breakdown of key equipment and processes.
1. Scrubbing Machine
– Capacity: 50–500 t/h
– Power: 30–200 kW
– Removes >90% of surface contaminants
2. Jaw Crusher (Primary Crushing)
– Feed Size: ≤1,500 mm
– Output Size: 150–300 mm
– Motor Power: 75–250 kW
3. Cone Crusher (Secondary Crushing)
– Output Size: 20–50 mm
– Capacity: 100–800 t/h
– Hydraulic adjustment for precise control
4. Sand Maker (Tertiary Processing)
– Produces 0–5mm fine aggregates
– Shaping rate: ≥90%
Raw ore → Scrubbing → Primary crushing → Secondary crushing → Screening → Sand making → Grading → Finished products.

Q1: How to reduce over-crushing?
A: Optimize crusher settings and use multi-stage screening.
Q2: What’s the lifespan of wear parts?
A: Manganese steel liners last ~6 months under normal conditions.
A project in Australia processed hematite ore (Fe content: ~55%).
