Common Faults and Maintenance Points of Cone Crusher - How to select Wear-resistant Liner

As the core crushing equipment in the mining, building materials and other industries, the operating stability of the Cone Crusher directly affects the production efficiency. However, in long-term high-load operation, various faults are inevitable in the equipment. This article will analyze the common faults and maintenance precautions of the cone crusher, and introduce the professional solutions of Chengdu Zhixin Refractory Technology Co., Ltd. in the field of wear-resistant liner.

1. Common Faults and Causes of Cone Crusher

1. Spindle Fracture
Spindle fracture is a serious fault of the cone crusher, which is usually caused by the following reasons:

* Overload operation: Uncrushed metal foreign matter enters the cavity, causing instantaneous overload.

* Poor lubrication: Insufficient oil film between the spindle and the bushing, causing dry friction and high-temperature deformation.

* Fatigue damage: After long-term high-load operation, the spindle metal fatigue accumulates.

** Solution: Strengthen iron removal management, regularly check the oil quality and oil pressure of the lubrication system, and avoid overload operation of the equipment.

2. Liner wears too fast
The cone crusher liner (Concave and Cone Mantle) is directly involved in crushing and has a high wear rate. If the service life is abnormally shortened, it may be related to the following factors:
*Tough material hardness: granite, basalt, etc. have a large impact on the cone lining.
*Unqualified wear-resistant materials: Ordinary high manganese steel is prone to rapid wear under low impact conditions.
*Improper assembly: The gap between the liner and the machine body is too large, resulting in looseness and eccentric wear.

**Solution: Choose a wear-resistant liner that matches the material characteristics, such as the ultra-wear-resistant composite liner developed by Chengdu Zhixin Refractory Technology Co., Ltd., which has a hardness of HRC65 or above and a service life 2-3 times longer than traditional materials.

3. Lubricating oil temperature is too high
Abnormal oil temperature may be caused by the following reasons:
*Cooling system failure: radiator blockage or reduced water pump efficiency.
*Bearing damage: rolling element wear generates additional friction heat.
*Oil contamination: metal debris or water mixed with lubricating oil.

**Solution: Clean the cooler regularly, monitor the cleanliness of the oil, and replace the filter element in time.

4. Abnormal vibration
Excessive vibration of equipment is usually related to the following problems:
*Loose foundation: broken anchor bolts or cracked concrete base.
*Dynamic balance failure: uneven wear of main shaft or rotor parts.
*Liner fall off: loose fastening bolts cause liner displacement.

**Solution: Stop the machine to check fasteners and use laser centering instrument to correct dynamic balance.

2. Precautions for maintenance of cone crusher

1. Regular lubrication and maintenance

Use lubricating oil that meets the standards and test the oil quality every 500 hours.

Pay attention to the grease filling cycle of main shaft bearings and gears.

2. Optimization of wear-resistant parts selection
Select the liner material according to the characteristics of the crushed material (such as hardness and silicon content).

It is recommended to use the composite wear-resistant plate of Chengdu Zhixin Refractory Technology Co., Ltd., which adopts vacuum casting process, combines high chromium alloy and tungsten carbide particles, and has balanced impact resistance and wear resistance.

3. Real-time monitoring of operating parameters
Pay attention to data such as current, oil pressure, temperature, etc., and find abnormalities in time.

4. Preventive maintenance
Check the sealing of the hydraulic system every 3 months, and perform flaw detection on the main shaft every year.

3. Chengdu Zhixin Refractory Technology Co., Ltd. - Wear-resistant solution expert
As a leading wear-resistant material manufacturer in southwest China, Chengdu Zhixin Refractory Technology Co., Ltd. focuses on:
- High wear-resistant composite lining: suitable for cone crusher, jaw crusher, impact crusher and other equipment, serving customers including Zijin Mining, Anshan Iron and Steel Mining, Tongwei Group, Hesheng Silicon Industry and other companies.

Case: The cone crusher lining customized by CSG Group in our company has a capacity of crushing quartz stone that is 3 times the capacity of the conventional cone lining they used before. The previous conventional lining could only work 320 hours, but after using Zhixin Refractory wear-resistant lining, the service life increased to nearly 1000 hours. It greatly increased their production capacity and saved costs.

The stable operation of the cone crusher is inseparable from scientific maintenance and the support of high-quality wear-resistant parts. Choosing wear-resistant products from professional manufacturers can significantly reduce downtime and improve economic benefits.
