The Marvelous Mandible: Demystifying the Double Toggle Jaw Crusher

The double toggle jaw crusher is a marvel of engineering, designed to achieve maximum efficiency and productivity in crushing operations. It is characterized by its sturdy, yet lightweight construction, combining the advantages of both single and double toggle jaw crushers. The double toggle jaw crusher consists of a swing jaw, a stationary jaw, an eccentric shaft, a toggle plate, and a tension rod. The swing jaw is moved by a cam or pitman mechanism, acting like a lever to create a crushing motion. The eccentric shaft is driven by a motor, transmitting rotational motion to the swing jaw through the toggle plate. The tension rod ensures the proper alignment of the toggle plate, maintaining the proper angle between the swing and stationary jaws.

Engaging the Gears: Exploring the Intricacies of Jaw Crusher Operation

To understand the operation of the double toggle jaw crusher, we need to delve into the intricate details of its gears. The swing jaw is connected to the eccentric shaft by a pair of toggle plates. These plates act as a link between the swing and stationary jaws, allowing the swing jaw to move in a circular motion. As the swing jaw moves, it compresses the material against the stationary jaw, crushing it into smaller pieces. The circular motion of the swing jaw is achieved through the rotation of the eccentric shaft, which is driven by a motor. The motor provides the necessary power to overcome the resistance of the material being crushed, ensuring smooth and efficient operation of the jaw crusher.

Crushing Efficiency Unveiled: Unlocking the Secrets of the Double Toggle Jaw Crusher

The double toggle jaw crusher is renowned for its high crushing efficiency, which is achieved through its unique design and advanced technology. One of the key factors contributing to its efficiency is the angle between the swing and stationary jaws. This angle, known as the nip angle, determines the crushing capacity of the jaw crusher. A smaller nip angle results in a higher crushing capacity, as it allows the material to be crushed more effectively. Additionally, the double toggle jaw crusher features a larger feed opening, allowing larger pieces of material to be fed into the crushing chamber. This results in a higher throughput and faster processing of the material, further enhancing the crushing efficiency of the jaw crusher.

Beyond the Surface: Probing the Inner Mechanisms of Jaw Crusher Technology

While the double toggle jaw crusher may seem like a simple piece of machinery, its inner workings are anything but. The cam or pitman mechanism, which drives the swing jaw, is just one example of the complex mechanisms at play. The tension rod, for instance, ensures the proper alignment of the toggle plate, preventing it from slipping or becoming misaligned during operation. The toggle plate itself is a crucial component, as it transmits the crushing force from the swing jaw to the stationary jaw. Understanding the inner mechanisms of the jaw crusher technology allows us to appreciate the engineering brilliance behind its design and enables us to unlock its full potential in crushing operations.


The double toggle jaw crusher is a remarkable piece of machinery that has revolutionized the mining industry with its efficient and reliable performance. From its sturdy construction to its ingenious mechanisms, every aspect of the jaw crusher is designed to maximize its crushing efficiency and productivity. With Zenith as a trusted supplier of industrial crushing and grinding equipment, mining companies can rest assured knowing that they have access to high-quality and innovative solutions for their crushing needs. As technology continues to evolve, the double toggle jaw crusher will undoubtedly remain a force to be reckoned with in the mining industry.
