Jaw crusher is mainly used for the medium-granularity crushing of all kinds of ores and large materials in mine, metallurgy, building material, highway, railway, water conservancy and chemistry. The maximum compression strength of the materials to be crushed is 320MPa.

Its structure is simple and firm, reliable in work, convenient in maintenance and repair, and low in production and construction costs. It has long been widely used for coarse, medium and fine crushing of various ores and rocks with a compressive strength of 147-245MPa. Metallurgy, chemicals, building materials, power plants, transportation and other industrial sectors.

1. It adopts world-level manufacturing technology and high-end manufacturing materials.

2. More advanced movable jaw assembly makes it more durable. The movable jaw assembly uses high-quality steel casting and drives through two large-sized cast steel flywheels. In addition, the heavy eccentric shaft also adopts forging stock which makes JC series jaw crusher have extraordinary reliability.

3. The bearing pedestal adopts unitary cast steel structure. The unitary cast steel bearing pedestal can ensure comprehensive fitting with the crusher rack, and at the same time, greatly increase the radial strength of the bearing pedestal, whereas split type bearing pedestal does not have these advantages.

The movable jaw is hung on the mandrel and can swing left and right. When the eccentric shaft rotates, the connecting rod reciprocates up and down, which drives the two thrust plates to also reciprocate, thereby pushing the movable jaw to reciprocate left and right to realize crushing and unloading. This type of crusher adopts a crank double-link mechanism. Although the movable jaw is subjected to a great crushing reaction force, its eccentric shaft and connecting rod are not subjected to much force. Therefore, large-scale and medium-sized machines are often used in the industry. Come to crush hard materials. In addition, when this type of crusher works, the motion trajectory of each point on the movable jaw is an arc centered on the mandrel, the arc radius is equal to the distance from the point to the axis, the upper arc is small, and the lower arc is large. The crushing efficiency is low, and the crushing ratio is generally 3-6. Because of its simple movement trajectory, it is called simple swing jaw crusher.
