Revolutionary Insight: Unveiling the Hydraulic Diagram of Jaw Crusher


Zenith, based in China, is a well-known crusher and grinding mill manufacturer that offers equipment and solutions for customers from the aggregates, mining, and mineral grinding industry. With their expertise and commitment to innovation, they have brought about revolutionary changes in the field of jaw crushers.

Deconstructing the Innovation: Jaw Crusher Revolution

Jaw crushers have been an essential tool in the mining and minerals processing industry for decades. Their basic design involves a stationary jaw plate and a moving jaw plate, creating a motion that crushes the material against the fixed plate. However, the innovation lies in the hydraulic system that powers the movement of the jaw plates. This revolutionary addition has made jaw crushers more efficient, versatile, and safe to operate.

The hydraulic system in a jaw crusher plays a crucial role in its operation. It ensures smooth and controlled movement of the jaw plates, allowing the crusher to crush materials with precision and consistency. The hydraulic system consists of a series of components, including cylinders, pumps, valves, and pipes, all working together to provide the necessary power and control.

Unlocking the Secrets: Revealing the Hydraulic Diagram

To understand the hydraulic system of a jaw crusher, we need to unveil its diagram. At the heart of the system are hydraulic cylinders that provide the crushing force needed to compress the material. These cylinders are connected to a hydraulic pump, which supplies the necessary hydraulic fluid. The pump is controlled by a set of valves, allowing for precise control of the crushing process.

The hydraulic fluid flows through pipes and hoses, delivering the power from the pump to the cylinders. These pipes and hoses are carefully designed to withstand high pressures and ensure smooth operation of the system. The hydraulic fluid is also filtered to remove any impurities that could potentially damage the system.

Unveiling the Machinery: Inside the Jaw Crusher’s Blueprint

The hydraulic system of a jaw crusher is carefully designed to ensure its reliability and longevity. Each component is strategically placed and sized to provide optimal performance. The cylinders, for example, are designed to withstand the high crushing forces and are made from robust materials such as steel or cast iron.

The hydraulic pump is typically driven by an electric motor, ensuring a consistent and reliable power source. It is designed to provide the required oil flow and pressure to the cylinders, allowing for precise control of the jaw plates’ movement. The valves, on the other hand, regulate the flow of hydraulic fluid, controlling the speed and force of the jaw plates’ movement.

A Paradigm Shift: Understanding the Revolutionary Hydraulic System

The introduction of the hydraulic system in jaw crushers has brought about a paradigm shift in the way these machines operate. The hydraulic system provides several advantages over traditional mechanical systems. Firstly, it allows for precise control of the jaw plates’ movement, resulting in better crushing efficiency and product quality.

Secondly, the hydraulic system ensures the safety of the operator and the machine. It includes various safety features such as pressure relief valves and overload protection, which prevent damage to the crusher in case of excessive force or unexpected events. These safety features make jaw crushers safer to operate, reducing the risk of accidents and injuries.

Lastly, the hydraulic system improves the versatility of jaw crushers. With the ability to adjust the jaw plates’ movement and the crushing force, these machines can handle a wide range of materials and applications. Whether it is crushing hard rock or recycling concrete, the hydraulic system allows for optimal performance in various conditions.


In conclusion, the hydraulic diagram of a jaw crusher reveals the inner workings of this revolutionary machine. The addition of a hydraulic system has transformed jaw crushers, making them more efficient, versatile, and safe to operate. By understanding the hydraulic system and its components, we can appreciate the engineering behind these powerful machines and their potential for enhancing mineral processing operations. Zenith, as a leading crusher and grinding mill manufacturer, continues to push the boundaries of innovation, providing customers with cutting-edge equipment and solutions that drive the industry forward.
