Causes and solutions of cone crusher sudden holding

With the continuous advancement of industrialization process, cone crusher as an important ore crushing equipment, plays an important role in mining, construction, cement and other industries. However, in the process of use, sometimes you will encounter the problem of sudden locking of the cone crusher, which not only affects the production efficiency, but also may lead to equipment damage, resulting in unnecessary costs and waste of time. This paper will discuss the main causes and solutions of cone crusher sudden lock.

First, the cause of death analysis

1. Hard or too large material into

When non-crushing material (such as iron, large stone) enters the crushing chamber, it exceeds the crushing capacity of the equipment design, which may cause the moving cone to stick. This is often the case when the raw material pre-screening is inadequate or the feed control system fails.

2. The lubrication system is faulty

Poor lubrication is one of the common causes of cone crusher lock. Insufficient supply of lubricating oil or substandard quality will lead to overheating of bearings, increased wear, and eventually stuck. In addition, the blockage of the lubricating oil path will also cause the key components to not be effectively lubricated.

3. Foreign matter or accumulation inside the equipment

During long-term operation, the accumulation of small materials that are not cleaned up in time in the crushing chamber, or foreign bodies (such as falling parts fragments) are stuck, which may gradually accumulate and eventually lead to hugging.

Second, the solution strategy

1. Strengthen source control and pre-screening

Ensure that the raw materials are strictly pre-screened, and remove too large and hard non-broken materials, which can effectively reduce the risk of holding. Advanced vibrating screening equipment is used to improve screening efficiency and accuracy.

2. Optimize lubrication system and maintenance

Regularly check the lubrication system, including the oil pump, oil line, screen, etc., to ensure that the lubrication grease is clean, adequate and meets specifications. Implement regular grease replacement plan to avoid the use of inferior grease. At the same time, strengthen the monitoring and maintenance of key components such as bearings, and stop the inspection in time once abnormalities are found.

3. Regular cleaning and inspection

Make a strict equipment maintenance plan, regularly clean the accumulated material and foreign matter in the crushing chamber, check and tighten all connectors to prevent loosening and falling off to become the source of internal blockage. Use downtime to conduct thorough internal inspections to identify and eliminate potential hazards in a timely manner.
