Jaw crushers come in various models and specifications to cater to different crushing needs and applications. Here are some common types of jaw crusher models along with their specifications:
1.By Feed Opening Width and Length
1-1.PE Series: This is a common traditional jaw crusher model. For example, PE250×400, where "250" represents the width of the feed opening as 250mm and "400" represents the length of the feed opening as 400mm. Its processing capacity is relatively small, generally 5-20t/h, and it is suitable for small - scale stone processing plants or occasions where the output requirement is not high.
1-2.The jaw crusher PE - 600×900 model has a feed opening width of 600mm and a length of 900mm, with a processing capacity of 90 - 180t/h. It can be used to process larger pieces of stone and is widely used in medium - scale mining and construction stone processing.
2.By the Motion Characteristics of the Moving Jaw
2-1.Simple Swing Type: This type of jaw crusher has a simple structure, and the motion trajectory of the moving jaw is approximately an arc centered on the suspension shaft. For example, the traditional PE - series simple - swing jaw crusher, its working principle is that the rotation of the eccentric shaft drives the moving jaw to swing periodically, thus realizing the crushing of materials. Its crushing ratio (the ratio of the maximum particle size before crushing to the maximum particle size after crushing) is generally between 3 - 6, and it is suitable for coarse crushing operations and can initially crush large pieces of ore, rock and other raw materials into smaller particles.
2-2.Complex Swing Type: The motion trajectory of the moving jaw is more complex, with not only up - and - down swings but also left - and - right movements. Like the PEX - series complex - swing jaw crusher, its crushing ratio is relatively large, up to 4 - 8 or so, and it can crush materials more effectively into finer particles. This model of crusher has a better crushing effect when dealing with some materials with high hardness and large particle size, and the production efficiency is higher than that of the simple - swing type.
3.By Purpose and Industry
3-1.Coarse - Crushing Type: It has a large feed opening and high crushing force and is mainly used in the primary crushing stage of mining. For example, the C - series coarse - crushing jaw crusher adopts an advanced crushing cavity design and can adapt to the coarse crushing of various hardness ores such as granite and iron ore. It has a strong processing capacity and can efficiently crush large - block ores into a particle size suitable for the next - stage crushing equipment.
3-2.Medium - and - Fine - Crushing Type: The feed opening is relatively small, but it can crush materials more finely. For example, the JC - series jaw crusher is widely used in the medium - and - fine - crushing of construction stones. It can further crush the stones after coarse crushing into smaller particles to meet the strict requirements of the construction industry for stone particle size, such as the production of high - quality concrete aggregates.
4.By Driving Method
4-1.Electric - Motor - Driven Type: This is the most common driving method, in which the motor drives the pulley and the eccentric shaft to drive the movement of the moving jaw. Its advantages are stable power, easy control and maintenance. For example, most PE - series jaw crushers are motor - driven, and the motor power ranges from a few kW to hundreds of kW according to the model size, which can meet the needs of different production scales.
4-2.Hydraulic - Driven Type: The moving jaw is driven by a hydraulic system. This driving method can achieve more precise motion control. For example, some new - type intelligent jaw crushers adopt hydraulic driving. It can flexibly adjust the motion parameters of the moving jaw according to the properties of materials and crushing requirements. Moreover, when an uncrushable object enters the crushing cavity, the hydraulic system can make the moving jaw automatically retreat to avoid equipment damage and has a good overload protection ability.
Each type of jaw crusher has its own advantages and is suitable for different applications. When selecting a jaw crusher, consider factors such as the material to be crushed, required capacity, operating conditions, and budget to choose the most appropriate model for your needs.
