Steel Bushing

The jaw crusher is used in the first process of crushing all kinds of ores and rocks. It can process various ores with a compressive strength of no more than 320MPa to medium particle size at one time. It often forms a complete set of sand and stone production lines with cone crushers, counter impact crushers, sand-making machines, etc., which are widely used in mines, metallurgy, chemical industry, building materials, electricity Power, water conservancy, transportation and other fields. PE series is used for coarse crushing operations, and PEX series is used for medium crushing or fine crushing operations to meet different crushing needs.
It is a kind of crushing equipment with simple structure and stable performance. With its efficient crushing ability, it has become one of the core equipment for material crushing in mines and various industrial fields.

The birth of the new generation of jaw crusher JC is due to the accumulation of rich experience and the large adoption of computer simulation and CAD design. Compared with the old generation of jaw crushers, the JC crusher has increased its own strength and reduced the self-weight of the equipment. Its high yield and low cost make it the first choice of jaw crusher for the majority of users.
The JC jaw crusher is designed using modern CAD technology, and all models are analysed by finite element technology to ensure that the internal stress level is within the appropriate range, which ultimately makes the JC crusher have the characteristics of high structural strength and light equipment weight.
It strengthens its own strength and reduces the self-weight of the equipment. It has the advantages of high yield, low cost, high structural strength and light equipment weight.

Star Machinery EC series jaw crusher is developed and designed based on crushing various hard rock conditions. It adopts an innovative modular and welding-free frame structure, thus giving the equipment excellent fatigue resistance, reliability and multiple installation methods. Thanks to the precise and balanced overall structure, the EC series jaw crusher is economical and easy to install. With the use of special high-quality cast steel components and durable wear parts, it is given excellent applicability, outstanding economy and low operating costs.
Based on the development and design of various hard rock conditions, it adopts an innovative modular and non-welded frame structure, which has the advantages of economical and simple installation.

The impact crusher is configured in the middle crushing after the coarse crusher, which can crush ores and rocks with a compressive strength of no more than 360 mPa, with the characteristics of large processing capacity and fine discharge. The crushed product is cubic, with low needle-like content and no internal cracks. It is the first choice equipment for the production of high-quality stone in high-grade highways, water conservancy, airports, construction and other industries.
It is used for coarse crushing and medium crushing. It can process pressure-resistant ≤360 megapascal ore rocks. The processing volume is large, the discharge is fine, and the finished product is cubic, which is suitable for high-quality stone production in highways, water conservancy and other industries.

This series of crushers is used to crush all kinds of ores and rocks of medium hardness or higher. It has the characteristics of reliable structure, high production efficiency, convenient adjustment and economy. Its spring insurance system is an overload protection device that can make the foreign iron block pass through the crushing cavity without harming the machine. It adopts two sealing forms of dry oil or water to isolate the stone powder from the lubricating oil and ensure reliable operation. The form of the crushing cavity is determined by the purpose of the ore. The standard type is suitable for medium crushing, medium-sized, and the short-head type is suitable for fine crushing.
It has the advantages of high production efficiency, low energy consumption, uniform particle size of finished products, extended service life and so on.

It is mainly used in the secondary and tertiary crushing links of the production line. It has a wide range of applications and can be used in industries such as metallurgy, building materials, road construction, chemical industry and so on. It can easily crush all kinds of ores and rocks of medium hardness and above, without worrying about the problem that the hardness of the material is not suitable enough. This equipment is divided into two models. The standard type is mainly used for coarse and medium crushing operations, and the short-head type is suitable for medium crushing and fine crushing.
It is usually used in secondary crushing and tertiary crushing. It is suitable for crushing all kinds of ores and rocks of medium and above hardness.
