For hobbyists or small-scale miners, building a homemade gold wash plant can be cost-effective. Here’s a simplified approach using basic materials and machinery.
Key Components:
1. Hopper & Grizzly: A sloped hopper with a grizzly screen (10–20mm spacing) to filter large rocks.
2. Trommel or Sluice Box: A rotating trommel (1–2m long, 300–500mm diameter) or a sluice box with riffles to trap gold.
3. Water Pump & Hoses: A 1–2 HP pump (flow rate: 50–100 GPM) to supply water.
4. Conveyor/Sluice Matting: Rubber matting or miner’s moss for gold recovery.
Basic Steps:
– Assemble the hopper and grizzly to pre-screen material.
– Feed material into the trommel/sluice, using water to wash away lighter sediments.
– Collect concentrates in a catch basin for further panning.
A typical sand and aggregate production line includes:
Core Equipment:
1. Jaw Crusher (Primary Crushing): Processes raw stone (e.g., granite/basalt) into 150–300mm chunks. Model example: PE-600×900 (Capacity: 50–160 t/h).
2. Cone/Impact Crusher (Secondary Crushing): Reduces material to 20–40mm. Model example: HP300 (Capacity: 100–200 t/h).
3. Vibrating Screen: Classifies material into sizes (e.g., 0–5mm, 5–10mm). Model example: 3YK2460 (Capacity: 80–150 t/h).
4. Sand Maker (VSI Crusher): Produces fine sand (0–5mm). Model example: VSI-7611 (Capacity: 60–180 t/h).
