PF-1315 Impact Crusher Liner

PF-1315 Impact Crusher Liner Introduction

The PF-1315 impact crusheris a medium-to-large-scale crushing equipment commonly used in the mining, building materials, and metallurgical industries. Its wear-resistant liner is one of the core wear parts, directly affecting the equipment's crushing efficiency and service life. High-quality liners effectively resist material impact wear, reducing downtime and replacement frequency, and improving production efficiency.

Key Functions of the Liner

• Protects the rotor and casing: Reduces equipment damage caused by direct material impact

• Optimizes crushing efficiency: Ensures a stable material impact angle and improves finished product particle size uniformity

• Extends equipment life: Highly wear-resistant materials reduce maintenance costs and overall operating expenses

PF-1315 Liner Material Comparison (High Manganese Steel vs. High Chromium Alloy)

Under different operating conditions, the choice of liner material directly affects wear resistance and economic efficiency. Below is a comparison of two mainstream materials:

Features	High manganese steel liner	High chromium alloy liner
Hardness (HRC)	18-22	58-62
Wear resistance	Medium, suitable for low to medium hardness materials	Extremely high, suitable for high hardness materials (such as granite and basalt)
Toughness	High, strong impact resistance	Relatively low, requires a buffer structure
Price	Relatively low	Relatively high
Applicable working conditions	Medium hardness materials such as limestone and coal gangue	Highly abrasive materials such as iron ore and quartz sand

Purchasing Recommendations:

• Limited Budget + Low to Medium Wear Conditions → Choose High-Manganese Steel Liner

• High Wear + Long Life Requirements → Choose High-Chromium Alloy Liner

PF-1315 Liner Key Parameters and Compatible Models

1. Standard Liner Parameters (Customizable)

• Compatible Models: PF-1315 Impact Crusher (Compatible with mainstream brands such as Shibang and Sandvik)

• Dimensions: Customizable based on rotor size, common thickness 50-100mm

• Mounting Method: Bolt-on, supports quick-release design

2. How to Determine Whether a Liner Needs Replacement?

• Signs of Wear: Depressions >10mm deep or cracks on the liner surface

• Decreased Efficiency: Crushing output decreases by more than 10%, resulting in uneven finished product particle size

• Abnormal Noise and Vibration: A noticeable sound of material hitting metal and increased equipment vibration

Liner Replacement Procedure (Illustrated Guide)

1. Shut down and disconnect power → Ensure safe operation

2. Remove the old liner → Loosen the bolts using a hydraulic wrench

3. Clean the mounting surface → Remove any residual material and rust

4. Install the new liner → Tighten the bolts diagonally (to avoid uneven force)

5. Test Run → Run the liner for 10 minutes without load to confirm there is no abnormal vibration

How can I extend the life of my liner?

1. Regular Inspection: Check the liner for wear every shift.

2. Evenly feed the material: Avoid large pieces of material directly impacting the liner.

3. Timely rotation: Reverse the liner when symmetrical wear occurs.

Proper selection and maintenance of the PF-1315 impact crusher liner can significantly reduce equipment operation and maintenance costs. For cost-effective liners or technical guidance, please contact a professional manufacturer for free sample testing! Choose high-quality materials: High-chromium alloy liners have a lifespan 2-3 times that of high-manganese steel.
