Jaw crusher is a mechanical equipment used for coarse and medium crushing, mainly used for crushing rocks and ores of various hardness. It crushes materials into smaller particles through the squeezing action of two jaw plates.
Main structure
Frame: the main structure that supports all components.
Moving jaw: movable jaw plate, driven by eccentric shaft.
Fixed jaw: fixed jaw plate, forming a crushing chamber with the moving jaw.
Eccentric shaft: drives the moving jaw to reciprocate.
Flywheel: stores energy to help the machine run smoothly.
Adjustment device: adjusts the size of the discharge port and controls the crushing particle size.
Lubrication system: ensures lubrication of bearings and moving parts.
Working principle
The motor drives the eccentric shaft through the pulley, driving the moving jaw to reciprocate. After the material enters the crushing chamber, it is crushed by the squeezing action of the moving jaw and the fixed jaw. The crushed material is discharged from the discharge port.
Advantages
Simple structure: easy to manufacture and maintain.
Efficient crushing: suitable for high hardness materials.
Adjustable particle size: The discharging particle size can be controlled by adjusting the device.
Wide range of applications: It can be used in mining, construction, metallurgy and other fields.
Application fields
Mining: Crushing ore.
Construction: Crushing construction waste and concrete.
Metallurgy: Crushing metallurgical raw materials.
Chemical industry: Crushing chemical raw materials.
Maintenance and care
Regular lubrication: Ensure the lubrication of bearings and moving parts.
Check wear: Check the jaw plate and other wearing parts regularly.
Tighten bolts: Check and tighten all bolts regularly.
Clean the crushing chamber: Clean the residual material in the crushing chamber regularly.
Safety precautions
Protective device: Ensure that all moving parts have protective covers.
Emergency stop: Install an emergency stop button.
Operation training: Operators need to undergo professional training.
Jaw crushers are widely used in many industries because of their high efficiency, reliability and easy maintenance.
