Jaw crushers are available in many models. Common product series include traditional PE jaw crushers, PEW European-type jaw crushers, and C6X series jaw crushers. These series differ in frame construction, crushing chamber design, discharge opening adjustment, and equipment configuration.
Jaw crusher model numbers are often related to feed opening dimensions. For example, PE600×900 indicates a feed opening measuring 600×900mm. However, PEW and C6X series also use manufacturer-specific naming conventions. Their actual dimensions and performance specifications should be checked against the corresponding product documentation.
PE Series Traditional Jaw Crushers
PE series jaw crushers are a common type of traditional jaw crusher. They are mainly used for primary crushing in mining, aggregate production, and building materials processing. Their design is well established, and many models use a shim adjustment system to control the discharge opening. They are suitable for a wide range of conventional crushing applications.
Common models include PE400×600, PE500×750, PE600×900, PE750×1060, PE900×1200, and PE1200×1500.
The PE600×900 model is also commonly known as the 69 jaw crusher. It has a feed opening measuring 600×900mm. The PE750×1060 model has a larger feed opening of 750×1060mm and is generally used for crushing operations with higher capacity requirements.
Maximum feed size, discharge opening range, and processing capacity vary between models. Specifications can also differ between manufacturers, even when they use the same model designation. Actual processing capacity should therefore be confirmed from the manufacturer's technical data rather than estimated from the model number alone.
PEW Series European-Type Jaw Crushers
The PEW series is also known as the European-type jaw crusher. It features an updated frame and crushing chamber design. Depending on the model, its configuration may include an integral cast-steel bearing housing, a heavy-duty eccentric shaft, and a hydraulic wedge adjustment system for the discharge opening.
Common models include PEW400×600, PEW760, PEW860, and PEW1100. Model designations and specifications may vary between manufacturers.
For example, according to one manufacturer's published specifications, the PEW860 has a feed opening of 860×1100mm, a maximum feed size of 720mm, and a processing capacity of 200 to 500 tonnes per hour. The PEW1100 has a feed opening of 1100×1200mm, a maximum feed size of 930mm, and a processing capacity of 300 to 650 tonnes per hour. <Cite refs={["turn346606search1","turn932188view1"]}/>
The hydraulic adjustment mechanism changes the discharge opening by moving the adjustment wedges, reducing the amount of manual work required. PEW jaw crushers are used in mining, metallurgy, chemical processing, and building materials production. The appropriate model should be selected according to feed material properties, feed size, and production requirements.
C6X Series New-Generation Jaw Crushers
The C6X series is a newer generation of jaw crushers developed by certain equipment manufacturers. Compared with traditional PE jaw crushers, this series incorporates changes to the frame construction, crushing chamber, and discharge opening adjustment mechanism.
Some models use a detachable, non-welded frame assembled with bolts instead of a conventional welded frame. The discharge opening uses a double-wedge adjustment system, which can be configured for mechanical or hydraulic adjustment depending on the model. Other design features may include elastic limiting and vibration damping devices, as well as an integrated motor base.
Common models include C6X80, C6X100, C6X110, C6X125, C6X145, C6X160, C6X180, and C6X200. The actual model range depends on the manufacturer's product catalog.
According to specifications published by Liming Heavy Industry:
C6X160: Feed opening of 1200×1600mm, maximum feed size of 1020mm, and processing capacity of 410 to 1150 tonnes per hour.
C6X200: Feed opening of 1500×2000mm, maximum feed size of 1200mm, and processing capacity of 610 to 1510 tonnes per hour. <Cite refs={["turn597309search8","turn597309search5"]}/>
These figures refer to the specific manufacturer's models. Similar series from other manufacturers may have different specifications. Actual throughput also depends on material properties, feed particle size, discharge opening settings, and feeding conditions.
What Parameters Should Be Considered When Selecting a Jaw Crusher?
Selecting a jaw crusher requires more than checking the model number or feed opening dimensions. The machine must match the actual production conditions.
Feed opening and maximum feed size
The feed opening determines the size of material that can enter the crusher, but its dimensions are not the same as the maximum permissible feed size. Both parameters should be checked during equipment selection. The feed material must remain within the machine's specified size limit to avoid blockages and excessive loading.
Material hardness and abrasiveness
Different jaw crusher models have different capabilities when processing materials of varying hardness and abrasiveness. Hard rocks such as granite and basalt place different demands on the machine and jaw plates than materials such as limestone.
Equipment selection should take account of compressive strength, abrasiveness, and jaw plate material. The maximum compressive strength specified for one model should not be treated as a universal limit for all jaw crushers.
Discharge opening adjustment range
The discharge opening directly affects product particle size and processing capacity. Select a crusher with an adjustment range that meets the requirements of subsequent screening, secondary crushing, or other processing operations.
The adjustment mechanism should also be considered. Depending on the model, the crusher may use shim adjustment, mechanical wedge adjustment, or hydraulic wedge adjustment. Each configuration has different operating and maintenance requirements.
Processing capacity and motor power
The rated processing capacity and motor power must match the requirements of the production line. Manufacturers generally publish capacity ranges based on specific materials and operating conditions. These figures should not be treated as guaranteed output under every site condition.
Other factors include bulk density, moisture content, feed size distribution, continuous feeding conditions, and daily operating hours. These factors are important when estimating the required processing capacity and selecting the appropriate crusher.
How to Select a Jaw Crusher for Different Production Scales
For small and medium-sized crushing operations, PE series jaw crushers can be considered according to feed size and required throughput. Their established construction and conventional configurations make them suitable for projects with clearly defined equipment budgets and primary crushing requirements.
When a production line requires more convenient discharge opening adjustment and additional features in the frame and auxiliary systems, PEW European-type jaw crushers are worth considering. Their advantages should be evaluated according to the actual hydraulic adjustment, lubrication, and frame configuration of the selected model.
For large mines and high-capacity aggregate production projects, larger jaw crushers such as the C6X series can also be evaluated. Selection should focus on maximum feed size, rated processing capacity, discharge range, installation dimensions, and motor power to ensure that the crusher matches the capacity of the entire production line.
Daily processing volume alone is not sufficient for selecting a jaw crusher. For example, two production lines with the same daily output requirement may need different hourly processing capacities if their operating hours differ.
