120-150 TPH River Pebble Crushing Production Line

Targeting the high hardness, low water content, and smooth surface of river pebbles, the production line uses a proven "Jaw Crusher + Cone Crusher + Vibrating Screen" core combination, which has been verified in over 200 river pebble processing projects worldwide, delivering excellent stability and cost-effectiveness.

1. Primary Crushing Stage: PE600X900 Heavy-Duty Jaw Crusher

As the first step in river pebble processing, the primary crusher is responsible for reducing large-size river pebbles (up to 800mm) to a particle size (<150mm) suitable for secondary crushing. The PE600X900 jaw crusher is customized for high-hardness materials:

          • Key Parameters: Feed inlet dimension 600×900 mm, maximum feed size 800 mm, processing capacity 160-250 TPH (matching the subsequent process load to avoid bottlenecks).

          • Core Advantages: Reinforced cast steel frame with thickened side plates, capable of withstanding the impact force of hard river pebbles.

          • Deep-cavity crushing chamber design (depth-to-width ratio 1:2.5) reduces material slipping, increasing primary crushing efficiency by 15%.

2. Secondary Crushing Stage: Symons Cone Crusher

After primary crushing, river pebbles (particle size ≤150mm) enter the cone crusher for medium crushing. CS110 cone crusher adopts the "layered crushing" principle, which is particularly suitable for hard and abrasive materials:

          • Key Parameters: Closed-side discharge opening 15-30 mm, processing capacity 130-160 TPH.

          • Core Advantages: Automatically adjusts the discharge port when encountering unevenly hard river pebbles, preventing equipment jamming and damage.

          • Optimized crushing cavity (designed for river pebbles): Reduces wear on the crushing wall and mantle by 25%, while ensuring the intermediate product particle size is uniform.

3. Auxiliary Equipment & System

The smooth and efficient operation of the entire production line depends on the precise coordination of auxiliary equipment:

          • Vibrating Feeder 4YK1860: Equipped with an anti-slip lining plate, it uniformly feeds river pebbles to the primary crusher, avoiding uneven feeding caused by the smooth surface of materials.

          • 4YK1860 Vibrating Screen: 4-layer high-frequency screen mesh design, with a screening efficiency of >95%, capable of separating 4 grades of finished products (0-5mm, 5-10mm, 10-20mm, 20-30mm) at one time.

          • PLC Automatic Control System: Realizes remote monitoring of key parameters (equipment temperature, load, output) and automatic adjustment of feed rate and discharge port, reducing manual operation by 60% and improving production stability.
