How PF-1315 Impact Crusher Efficiently Processes High-Rebar Content Construction Waste: A Practical Parameter Adjustment Guide

How Does the Impact Crusher Efficiently Process Construction Waste with High Steel Content? A Practical Parameter Adjustment Guide for PF-1315

Facing the challenge of construction waste with high steel content, how can the PF-1315 impact crusher achieve efficient crushing and aggregate recycling? This article delves deep into its core working principle - high-speed rotor projectile crushing technology. Combined with a practical parameter adjustment guide, it will teach you step by step how to flexibly set the feed size, rotation speed range, and screen configuration according to the material composition (such as concrete, bricks, and steel bars), significantly improving crushing efficiency and reducing wear and tear. Through real working condition case comparisons of the advantages of traditional equipment, it helps you avoid common misunderstandings and master the pre-screening + double - cavity process skills when the steel content exceeds 15%, truly turning construction waste into treasure!

Technical Principle

The impact crusher realizes material impact crushing through the high - speed rotation of the rotor. When the rotor rotates at high speed, the materials are thrown out at a high speed and collide with the impact board, which has a better effect on optimizing the aggregate particle shape. Compared with jaw crushers, the needle - shaped and flaky content in the aggregates produced by impact crushers is significantly lower. For example, the needle - shaped and flaky content in the aggregates produced by jaw crushers can reach about 30% - 40%, while the content in the aggregates produced by impact crushers is generally controlled within 15%.

Practical Operation Points

When dealing with construction waste with different steel bar ratios, you need to set different parameters:

• Steel content < 10%: For the feed size, it is recommended to control it within 300 - 500mm. The rotation speed can be set in the range of 1500 - 1800rpm. A single - stage screening with pre - iron removal can be adopted for the screening configuration.
• Steel content > 15%: The feed size should be reduced to 150 - 300mm. The rotation speed range is 1200 - 1500rpm. A two - stage screening with pre - iron removal strategy is recommended to ensure better separation of steel bars and aggregates.

Typical Scenario Simulation

In an urban demolition project, the PF - 1315 impact crusher was used to handle construction waste with a steel content of up to 20%. During the operation, it showed excellent stability. The equipment ran smoothly without any major breakdowns, and the qualified rate of the discharged materials reached over 90%, which fully demonstrated its high - efficiency performance.

Practical Tips

Here are some practical tips to help you operate the PF - 1315 impact crusher better:

• Check the rotor balance before starting the machine every day to ensure stable operation.
• Regularly clean the impact board and the crushing chamber to prevent material blockage.
• Inspect the wear of the hammerheads and replace them in time when the wear exceeds the standard.

Q&A

Here are some frequently asked questions and answers to help you better understand the PF - 1315 impact crusher:

• Q: Do I need to install a magnetic separation device? A: When dealing with construction waste with high steel content, it is recommended to install a magnetic separation device to effectively separate steel bars and improve the quality of recycled aggregates.
• Q: How often should I replace the hammerheads? A: The replacement frequency of hammerheads depends on the material hardness and the amount of processing. Generally, it is necessary to check the wear of hammerheads every 50 - 100 working hours and replace them when the wear is serious.
