Compound Crusher Machine
What Crushing Challenges Can Compound Crusher Machine Solve？
Compound Crusher Machine is designed for medium-hard and high-hard materials in secondary and fine crushing. Its vertical-shaft, screenless design prevents clogging when processing materials with high moisture content.
Zhengzhou Machrise has over 10 years of experience in crushing equipment R&D and on-site service. The machine accepts feed sizes up to 220mm, produces output between 3 and 5mm, and delivers capacity from 10 to 190 tons per hour. It supports both dry and wet operations.
How Does Compound Crusher Machine Work
Compound Crusher Machine operates on the "stone-on-stone" principle. Material enters vertically into a high-speed rotating impeller and is thrown against the impact plates under centrifugal force. Additional inter-particle collisions occur as material circulates within the vortex. The material then exits from the bottom in a straight-through discharge, forming a closed-loop system. The maximum crushing ratio reaches 30:1, the highest among vertical-shaft crushers in its class.
What Are the Technical Parameters of Compound Crusher Machine
| Model | Feed Size mm | Capacity t/h | Spindle Speed r/min | Motor Power kW |
|---|---|---|---|---|
| PFL-800 | ≤100 | 10-20 | — | 22 |
| PFL-1000 | ≤120 | 20-40 | 769 | 37 |
| PFL-1250 | ≤150 | 40-70 | 530 | 75 |
| PFL-1500 | ≤180 | 70-100 | 495 | 132 |
| PFL-1750 | ≤200 | 130-190 | 424 | 160 |
All models produce output between 3 and 5mm, with noise levels below 75dB.
How Does Compound Crusher Machine Perform in Real Production
In 2025, we deployed a PFL-1500 Compound Crusher Machine at Shaogang Songshan Co., Ltd. for limestone crushing in metallurgical lime production. The previous equipment experienced frequent screen clogging. After the machine was introduced, production stability improved significantly, and the plant developed standard procedures for common operational issues.
A 120t/h limestone aggregate line replaced its jaw-hammer crusher system with this equipment. Maintenance downtime dropped 18% to 22%, aggregate shape consistency improved, and energy consumption per ton decreased.
What Are the Core Advantages of Compound Crusher Machine
Compound Crusher Machine outperforms conventional crushers in three critical areas: clog-free operation with high-moisture materials, reduced maintenance downtime, and built-in safety features.
Clog-free operation with high-moisture materials.
Compound Crusher Machine achieves a crushing ratio of 30:1. The screenless design handles materials with up to 8% moisture content without clogging. Processing limestone with over 6% moisture, this machine ran 9 months without blockage, while a hammer crusher under the same conditions required shutdown 2-3 times per month. It is the only vertical-shaft crusher that maintains continuous operation above 5% moisture.
Durable structure with simplified maintenance.
The rotor experiences minimal wear. Horizontally mounted bearings have long service life and handle high-temperature materials like cement clinker. A hydraulic rear housing allows wear parts replacement without dismantling the main unit, reducing maintenance downtime .
Built-in safety with quality compliance.
An elastic mechanism automatically ejects unbreakable objects to protect the equipment. Core components use multi-alloy wear-resistant materials and comply with ISO 9001 and CE standards. The machine supports both dry and wet crushing without performance loss.
Which Materials Is Compound Crusher Machine Suitable For
Compound Crusher Machine handles a wide range of materials across different hardness levels. For medium-hard materials, it processes iron ore, sandstone, gypsum, blast furnace slag, coal gangue, limestone, and dolomite. For high-hardness materials, it handles bauxite clinker, silicon carbide, and glass raw materials. The machine also works well for raw meal, clinker, manufactured sand, and various metallurgical slags, making it a versatile solution for aggregate production, cement processing, and industrial mineral crushing.
How to Choose the Right Compound Crusher Machine Model
Selection depends on material hardness and moisture content. For compressive strength above 200MPa, Compound Crusher Machine is the recommended choice. For high-moisture materials, the screenless design prevents clogging. For frequent particle size adjustments, this equipment offers better precision than impact crushers, as adjustment is not affected by hammer wear. PFL-800 suits small lines; PFL-1500 and PFL-1750 are for large-scale operations.
Compound Crusher Machine FAQs
What is the delivery and installation timeline for Compound Crusher Machine?
Standard delivery takes 15 to 20 working days, with 2 to 3 days for on-site installation and commissioning.
Can Compound Crusher Machine integrate with an existing DCS system?
Yes, it comes with a remote control interface supporting the Modbus communication protocol.
What is the warranty policy for Compound Crusher Machine?
The machine has a 12-month warranty covering manufacturing defects, excluding wear parts like hammers and liners.
How does Compound Crusher Machine differ from a vertical shaft impact crusher?
A VSI crusher primarily uses impact energy. Compound Crusher Machine combines impact and shearing forces, delivering finer output and supporting both dry and wet operations.
