A Complete Dolerite Rocks 300 TPH Crushing & Screening Plant

Dolerite, known for its durability and high compressive strength, is an ideal material for producing aggregates used in road construction and infrastructure projects. To meet the growing demand for high-quality aggregates, we have engineered a complete 300 TPH dolerite crushing and screening plant. This plant is designed to efficiently process dolerite rock into precisely sized aggregates, including 19mm, 13.2mm, 9.5mm, 6.5mm, and crusher dust, catering specifically to the needs of the road and construction industries.

300TPH Dolerite Crushing Plant Configuration and Workflow

This complete stone crushing plant integrates robust machinery and advanced technology to ensure optimal performance and product quality. Here’s a breakdown of the plant’s configuration:

1.Primary Crushing Stage

● CA heavy-duty jaw crusher C125 serves as the primary crusher, reducing raw dolerite rocks (up to 750mm) to manageable sizes (approx. 150–200mm).

● Equipped with a vibrating grizzly feeder to regulate material flow and remove fine particles before crushing.

● Advantage: A 42-ton steel frame absorbs impact from large dolerite lumps, avoiding vibrations that damage nearby equipment.

2.Secondary Crushing Stage

● A high-capacity cone crusher HP300 further reduces the material to intermediate sizes (40–60mm).

● Operates in a closed circuit with a vibrating screen to ensure consistent feed size for the tertiary stage.

● Advantage: Produces cubical particles (flakiness rate <5%)—critical for road aggregates (even compaction) and concrete (strong bonding).

3.Tertiary Crushing and Screening Stage

● A vertical shaft impact (VSI) crusher fine-tunes the aggregate shape and produces crusher dust.

● Multi-deck vibrating screens classify the crushed material into the following final product sizes:

19mm

13.2mm

9.5mm

6.5mm

Crusher dust (0–5mm)

● Advantage: High-chromium steel concave and mantle resist dolerite’s wear, lasting 6–8 months. Four decks vibrating screen with custom mesh sizes (19mm, 13.2mm, 9.5mm, 6.5mm) ensure precise classification—no cross-contamination between sizes.

4.Material Handling and Storage

● Conveyor belts transport materials between stages and to designated stockpiles.

● Automated stacking systems ensure efficient storage and loading of finished products.

Key Features of the Plant

1.High Efficiency: Achieves a throughput of 300 tons per hour with minimal downtime.

2.Precise Sizing: Advanced screening technology ensures accurate aggregate gradation.

3.Durability: Built to handle the abrasive nature of dolerite, with wear-resistant components.

4.Versatility: Capable of producing multiple aggregate sizes to meet specific project requirements.

5.Dust Control: Integrated dust suppression systems maintain environmental compliance.

Applications of Final Products

● The plant’s output is tailored for road and construction applications:

● 19mm & 13.2mm Aggregates: Ideal for road base, sub-base, and drainage layers.

● 9.5mm & 6.5mm Aggregates: Suitable for asphalt mixes and concrete production.

● Crusher Dust: Used as a fine aggregate in concrete blocks, paving, and compaction.
