Jaw crusher, also known as jaw breaker or jaw breakers, fulfills the crushing process by simulating the movement of the two jaws of an animal. It has been widely used in many fields, such as mining, metallurgy, building materials, highway, railway, water conservancy, chemistry and so on. It can crush all kinds of materials with compressive strength no more than 320 Mpa.
Jaw crusher is not only able to be used together with mine-selecting and gravel processing equipment, but be used independently. The jaw crushers are also used as primary crushers and Secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 mpa.
As one of the most common mining equipment, stone jaw crusher appears earlier than other crushing machines. Jaw crushers (also called jaw breakers) are typically used as primary crushers, or the first step in the process of reducing rock, and are one of the main types of primary crushers in a mine or ore processing plant.
Our stone jaw crusher is developed based on many years of product development. The continuous improvement and refinement has made them the preferred Primary jaw crusher among professionals. This series of stone jaw crushers are divided into 11 models which can meet most capacity requirements in primary crushing and secondary crushing, with low power consumption and easy maintenance. Every feature of these primary crushers has been carefully designed to provide superior quality and performance. They are widely applied in areas of mining, metallurgy, construction, smelting, hydraulic and chemical industries, etc. Among this series of stone jaw crushers, large and medium-size stone jaw crushers are our competitive products; especially in designing and producing large-sized jaw crusher, we have already ranked the first place in China jaw crusher and foreign jaw crusher market.
The crusher in the first working procedure is called the main crusher. When fed to the jaw crusher, the materials are poured from the top inlet into the crushing chamber with jaw plate. The movable plate raises the bulk material up to the fixed jaw plate (chamber wall), and with the action of two plates, the materials are crushed into smaller-sized stone. The one which makes movable jaw plate work is an eccentric shaft, which is fitted through the whole body frame. And two flywheels fixed on both ends of the shaft make the eccentric motion, while the flywheels and the eccentric shafting bearing are often used with spherical roller bearing. Because the working circumstance of the bearing is quite rough, the bearing has to bear huge impact load, wear ability sewage, and high temperature. Though the working circumstance is so rough, the jaw crusher still should work reliably, for the bearing is the core part to ensure the production efficiency.

Stone crusher is suitable for crushing a variety of soft and hard ores and rocks, whose largest compression resistance is under 320MPa. The maximum size of the feeding materials must be less than what is required according to the maximum specification of technical parameters, and the aggregate jaw crusher is mainly used for secondary and fine crushing mid hardness ores and rocks in metallurgical industry, mining, chemistry, cement making industry, construction, refractory, pottery and porcelain industry, etc
