Bauxite, a primary aluminum ore, requires efficient crushing to optimize downstream processing. Roller crushers are ideal for this application due to their high compression strength and adjustable particle size control. Below is a detailed breakdown of equipment and specifications for a bauxite crushing and sand-making production line.
1. Roller Crusher
– Model: 2PG1500×800
– Roller Diameter: 1500 mm
– Roller Width: 800 mm
– Feed Size: ≤50 mm
– Discharge Size: 3–10 mm (adjustable)
– Capacity: 50–100 t/h
– Motor Power: 2×75 kW
2. Supporting Equipment
– Vibrating Feeder: GZD-1200×4900 (Capacity: 150 t/h)
– Belt Conveyor: B1000×20 m (Speed: 1.6 m/s)
– Sand Washer: XS-2900 (Capacity: 80 t/h)
The process begins with primary crushing using a jaw crusher, followed by secondary crushing with the roller crusher to achieve uniform particle size. The crushed material is then screened and washed to remove impurities, producing high-quality sand and aggregates for construction or metallurgical use.
Q1: What is the advantage of using a roller crusher for bauxite?
A: Roller crushers minimize over-crushing and produce cubical particles, reducing energy consumption compared to hammer crushers.
Q2: How to maintain roller crushers in high-abrasion environments?
A: Regularly inspect wear-resistant alloy rollers and lubricate bearings every 200 operating hours.
Project: Bauxite Processing Plant in Guinea
Solution: A 200 t/h line featuring two-stage crushing (jaw + roller crushers) and sand washing. The output met ISO 9001 standards for construction aggregates, with ≤5% fines content.
