Knowledge Points

Rust prevention maintenance knowledge for jaw crusher parts

Jaw crusher parts are mostly made of carbon steel and alloy steel. Long-term exposure to dust, rain, humid air, slurry and mineral water will cause electrochemical rust. Rust will accelerate wear, block lubrication gaps, reduce fitting accuracy

Jaw crusher regular disassembly inspection tutorial

Stop the crusher completely, cut off the main power supply, hang warning lock and tag. Release the hydraulic pressure if fitted with hydraulic adjustment / hydraulic clearing system.

Forbidden operation behaviors when running jaw crusher

Violating forbidden operations is the main cause of personal injury, component damage and sudden shutdown of jaw crusher. All operators must strictly avoid the following behaviors during equipment running

Correct feeding operation points of jaw crusher

Standard feeding is the core premise to stabilize output, reduce cavity blockage, lower abnormal wear of jaw plates, toggle plates and bearings, and avoid overload shutdown

Toggle plate breakage cause analysis of jaw crusher

The toggle plate (also known as bracket) of a jaw crusher is not only a force transmission component, but also a safety fuse part of the crusher. When uncrushable materials enter the crushing chamber or the machine is overloaded, the toggle plate is designed to fracture first to protect the main frame, eccentric shaft and jaw plate from damage

Noise failure elimination method of jaw crusher

Jaw crusher abnormal noise is one of the common on-site faults. Continuous harsh noise not only harms the operating environment and operators’ hearing, but also implies hidden mechanical damage

Abnormal Vibration Reason of Jaw Crusher – Popular Science

Excessive or abnormal vibration is one of the common warning signs of a jaw crusher. Continuous strong vibration will loosen bolts, accelerate wear of jaw plates and bearings, damage the foundation, and even cause sudden shutdown.

Jaw crusher overload shutdown fault troubleshooting

Common failure causes of jaw crusher and solutions

Methods to extend jaw plate service life of jaw crusher

Control feeding particle size strictly. Oversized stones frequently cause heavy impact and localized stress on jaw plates. Keep feed size within the equipment’s designed range

Why jaw plate of jaw crusher wears easily analysis

Jaw plate (tooth plate) is the main wear-resistant part of jaw crusher. It directly squeezes and impacts stone materials during crushing. Fast wear is one of the most common failures, which increases spare parts cost, reduces product granularity and lowers production efficiency

Lubrication System Maintenance Guide for Jaw Crusher

The lubrication system is the core guarantee for the normal operation of a jaw crusher. Good lubrication reduces friction and wear between moving parts, lowers operating temperature, prevents metal corrosion, and extends service life of bearings
