Product Overview

CRUSTION CJ Series Jaw Crushers are new, high-efficiency jaw crushers suitable for coarse and medium crushing of ores and rocks with compressive strengths ranging from 147 to 280 MPa. Featuring a simple structure, stable operation, low manufacturing costs, and convenient maintenance, they are extensively used in mining, water conservancy, construction materials, metallurgy, chemical engineering, and transportation industries. The CJ Series Jaw Crushers incorporate an innovative modular, weld-free frame structure that effectively eliminates stress concentration points, providing exceptional fatigue resistance and an exceptionally long service life. Their meticulously designed crushing chamber utilizes high centrifugal force, a steep toggle plate angle, and a small nip angle, combined with a large stroke and optimal rotational speed, enabling efficient crushing throughout the entire process—from feed opening to discharge opening—producing finer, more uniform products while reducing jaw plate wear. A robust moving jaw assembly, heavy-duty eccentric shaft, and large spherical bearings further ensure stable and reliable operation, making these crushers widely applicable for hard rock crushing and processing various materials, thereby creating greater production value for users at lower operating costs.

Working principle

The excellence of the CRUSTION CJ series jaw crushers stems from their design and manufacturing materials; even the smallest details are perfected to ensure maximum functionality and reliability. They feature a unique modular, weld-free frame structure: two hot-rolled steel side plates are securely bolted to a high-quality cast steel frame via precision-machined pins, preventing stress concentrations (such as welds) that could reduce durability under impact loads. The durable moving jaw assembly is made of high-quality cast steel and driven by two large cast steel or cast iron flywheels. Additionally, a forged heavy-duty eccentric shaft and four identically sized large rolling bearings give the CJ series jaw crushers exceptional reliability. Labyrinth seals protect the bearings, keeping the lubricant free from contamination. The integral cast steel bearing housing ensures perfect alignment with the crusher frame while avoiding unnecessary stress on the bearing housing—a problem inherent in split-type bearing housing designs. Throughout their service life, CJ series jaw crushers can meet users’ demands for continuous day-and-night operation; however, some maintenance is inevitable. Thanks to the use of cast steel components, these crushers remain economically repairable or refurbishable after years of operation, whereas similar repairs on crushers with other architectures would be extremely costly or even impossible.

Product Features

1. High reliability
It employs a unique design featuring a weld-free frame structure, in which two hot-rolled steel side plates are securely bolted to a high-quality cast-steel frame via precision-machined pins. This configuration prevents stress concentrations—such as those found in welds—and thereby avoids premature degradation of the equipment’s durability under impact loading.

2. More convenient operation
All CJ series jaw crushers are equipped with a dual-wedge hydraulic discharge opening adjustment system. The crusher’s discharge opening can be manually adjusted in just a few minutes using the tools provided, and it can also be remotely adjusted in seconds—even while the crusher is idling. This system is particularly effective when clearing the crushing chamber after a load‑bearing shutdown caused by a power outage.

3. High degree of automation
The automated control system provides overload protection, iron‑removal protection, discharge opening adjustment, and synchronized cavity clearing, while continuously monitoring parameters such as oil temperature, oil pressure, flow rate, load, and discharge opening size to ensure reliable equipment operation.

4. High Performance

The CJ series jaw crusher features a high centrifugal force and a steep toggle plate angle, resulting in a larger effective stroke at the bottom of the crushing chamber.

5. Smoother operation

The CJ series jaw crusher’s rubber vibration-damping devices and limit blocks effectively reduce the impact of the crusher on its foundation by absorbing peak vibration loads and permitting vertical and longitudinal displacement of the crusher.

6. Wide adaptability

CRUSTION has developed a variety of jaw plates, with continuously optimized tooth profiles and thicknesses, and selected appropriate manganese steel alloy materials, thereby increasing output while reducing operating costs.
