Crawler Mobile Crushing and Screening Station

Sled-Mounted Modular Jaw Crusher Line | High-Efficiency Primary Crushing Solution

In primary crushing for aggregate processing and mining, efficient feeding, powerful rock crushing, and flexible deployment are critical to market competitiveness. Our sled-mounted modular jaw crusher line integrates DLZGC vibrating feeders, DLEV jaw crushers, and sled-type steel structure design into an all-in-one system for vibrating feeding, primary jaw crushing, and conveying. Eliminating complex civil construction, it enables immediate production after deployment, delivering a high-adaptability, cost-effective solution for primary crushing of hard materials like granite, basalt, and iron ore.

1. Modular Design: 24h Deployment & Flexible Relocation

Breaking the infrastructure limits of traditional primary crushing lines, we adopt an integrated sled-type steel structure base to precisely integrate DLZGC vibrating feeders, DLEV jaw crushers, and heavy-duty discharge conveyors. The entire system is fully debugged at the factory — on-site, only ground leveling and power connection are required, and production can start within 24 hours. This drastically shortens project timelines and cuts high civil engineering and installation costs.

The base balances stability and mobility: it can be equipped with traction devices for short-distance quick relocation, ideal for open-pit mines, temporary stockyards, and aggregate processing for infrastructure projects. It also supports fixed deployment to meet long-term large-scale production needs. With seamless upstream-downstream connection, it directly interfaces with cone crushers and vibrating screens to build a complete "primary crushing - medium/fine crushing - screening" production line, ensuring continuous material flow.

2. Dual-Core Synergy: Robust Performance for Primary Crushing

Centered on "precision feeding + powerful rock crushing", the line leverages the synergy of DLZGC feeders and DLEV jaw crushers to achieve high-capacity, low-wear primary crushing, with a processing capacity of 150-1000 t/h for all hard material primary crushing needs.

2.1 Precision Feeding: DLZGC Series Vibrating Feeder

As the "material conveying hub" of the line, it combines feeding and slag treatment functions to ensure stable feeding for jaw crushers.

• High adaptability & anti-clogging: Compact size, light weight, low power consumption, and 11° inclination design enable large conveying capacity and anti-clogging performance. Bolt-connected slag covers are easy to disassemble and adjust, adapting to complex working conditions with mixed raw materials and slag.

• Intelligent control & energy saving: Excitation force is precisely adjusted by changing the eccentric block angle for flexible feed rate control. Silo-bottom feeding design reduces feeding height and significantly cuts energy consumption.

• Wide applicability: Handles raw materials and slag before primary crushers, with a passing capacity of 150-3000 t/h, perfectly matching the feeding needs of different jaw crusher models.

2.2 Powerful Rock Crushing: DLEV Series Jaw Crusher

As the "primary crushing core", it is designed for high-intensity crushing, processing materials with hardness ≤320 MPa — the optimal choice for primary crushing of hard materials like granite, basalt, and iron ore.

• Modular design & easy maintenance: Integrated motor bases save platform construction costs; modular structure enables quick disassembly and maintenance, reducing on-site operation costs. High-quality large-spec bearings ensure extended equipment service life.

• Efficient crushing & optimized particle shape: "V"-shaped crushing chamber design enhances crushing force for finer discharge; optimized nip angle, stroke, and higher rotation speed increase material crushing times, significantly improving throughput and efficiency.

• Intelligent safety & reliability: Hydraulic double wedge device enables precise, fast, and safe discharge opening adjustment; automatic lubrication system delivers quantitative oil injection for refined maintenance; elastic limit shock absorbers absorb peak loads, reducing foundation fatigue damage and extending overall equipment life.
