Jaw crushers are widely used primary crushing equipment in industries such as mining, building materials, and metallurgy, renowned for their simple structure, reliable operation, and convenient maintenance. When referring to a jaw crusher as "3 meters long and 1.3 meters wide," this usually refers to the overall dimensions of the equipment or the frame specifications, not the specific parameters of the crushing chamber.
According to industry convention, a jaw crusher approximately 3 meters long and 1.3 meters wide typically corresponds to a medium-sized model, such as PE-600×900 or similar specifications. The feed opening size for this type of equipment is generally around 600mm×900mm, with a maximum feed size of 500mm. The adjustable discharge opening range is usually 60–180mm, suitable for primary crushing of various ores, rocks, and construction waste with a compressive strength not exceeding 320MPa.

The processing capacity of a jaw crusher of this size is approximately 50–120 tons/hour, with the specific capacity depending on the material hardness, moisture content, and discharge opening settings. Its main structure includes core components such as a fixed jaw plate, a movable jaw plate, an eccentric shaft, a flywheel, and a frame. The power system typically uses a 45–75kW motor, achieving efficient crushing via belt drive.
It's worth noting that the total length of the equipment (3 meters) includes the motor and foundation support; sufficient space must be reserved for operation and maintenance during installation. The 1.3-meter width determines its requirements for plant access, facilitating transportation and layout planning.
Overall, the 3-meter long and 1.3-meter wide jaw crusher is a medium-capacity model, balancing efficiency and space requirements, suitable for small to medium-sized sand and gravel production lines or mobile crushing stations. Users should consider the actual characteristics of the raw materials, production needs, and subsequent process flows when selecting a model to achieve the optimal return on investment.
