gravel making plant rock mining machine

A gravel making plant typically involves several stages of processing raw rock into finished gravel products. The process usually includes mining, crushing, screening, and washing. Here’s an overview of the key components, including rock mining machines used in gravel production:

1. Rock Mining Machines (Extraction)
Before gravel production, rocks must be extracted from quarries or mines. Common machines include:
– Hydraulic Excavators & Loaders – For digging and transporting raw material.
– Drill Rigs – Used for blasting holes in hard rock formations.
– Bulldozers & Dump Trucks – For moving large volumes of rock to the processing plant.

2. Primary Crushing (Jaw Crusher)
– A jaw crusher breaks down large rocks into smaller pieces (6–10 inches).
– Suitable for hard rocks like granite or basalt.

3. Secondary Crushing (Cone Crusher or Impact Crusher)
– A cone crusher or impact crusher further reduces the rock size to 1–3 inches.
– Ensures uniformity for gravel production.

4. Screening (Vibrating Screens)
– Screens separate crushed rock into different sizes (e.g., ¾”, ½”, ¼”).
– Oversized material may be sent back for re-crushing.

5. Washing & Sand Removal (Log Washers or Sand Screws)
– Removes dirt, clay, and fine particles to produce clean gravel.
– Optional step if high-quality washed gravel is needed.

6. Stockpiling & Distribution
– Conveyors transport sorted gravel toockpiles.
– Loaders fill trucks for delivery to construction sites.

Types of Gravel Produced:
1. Crushed Stone Gravel – Angular edges, ideal for road bases.
2. Pea Gravel – Small, rounded stones for landscaping.
3. Bank Gravel – Naturally occurring mix of sand and stones.
4. Washed Gravel – Clean, free of fines for drainage applications.

Key Equipment Suppliers:
– Sandvik, Metso, Terex, Kleemann (crushers & screens)
– Caterpillar, Komatsu (mining equipment)
– McLanahan, Eagle Iron Works (washing systems)
