High-Efficiency Impact Crushing Solutions for Fine and Medium Crushing in the Building Materials and Mining Industries

Impact Crusher Equipment Overview

The PF Series Impact Crusher (PF0807–PF1315) is specifically designed for the medium and fine crushing of medium-hard materials (≤100 MPa), with a capacity of 250–750 t/h and a maximum feed size of 300 mm. High-speed impact crushing principle ensures excellent particle shape and a high crushing ratio. The heavy-duty rotor undergoes precise dynamic balancing for smooth operation. The hydraulic chamber opening system enables rapid maintenance, while wear-resistant alloy welding wire reinforces vulnerable components. An automatic lubrication system provides timed and metered lubrication.

Impact Crusher Equipment Highlights

Heavy-Duty Rotor with High Crushing Ratio: The robust rotor structure generates high inertia and strong impact force, resulting in a high crushing ratio and excellent product particle shape. The hammer plates are secured with a simple, reliable locking mechanism for quick installation.

Precision Dynamic Balancing for Low Vibration: The rotor undergoes precision machining and dynamic balancing, ensuring smooth operation with minimal vibration and extending equipment service life.

Hydraulic Chamber Opening for Quick Clearance Adjustment: Hydraulic opening of the housing allows rapid access to the crushing chamber for maintenance, and the clearance between the impact frame and the rotor is easily adjustable, reducing downtime.

Wear-Resistant Alloy for Extended Service Life: High-wear areas are reinforced with wear-resistant alloy welding wire, enhancing rotor durability, simplifying maintenance, and reducing costs.

Automated Lubrication Saves Labor: Timed, metered automatic oil supply ensures optimal bearing lubrication at all times, eliminating the need for manual grease replenishment and reducing labor intensity.

Wide Range of Industries: Suitable for the crushing of medium-hard materials in industries such as building materials, minerals, railways, highways, energy, transportation, and cement.

Impact Crusher Application Scenarios

Building Material Aggregate Processing: Medium and fine crushing and shaping of limestone to produce high-quality construction aggregates.

Medium and Fine Crushing of Ore: Secondary crushing of medium-hardness ore to supply material for subsequent mineral processing.

Cement Raw Material Preparation: Crushing and processing of cement raw materials such as clinker, slag, and limestone.

Railway and Highway Aggregates: Crushing and production of ballast and subgrade aggregates.

Energy and Industrial Waste: Crushing and volume reduction of materials such as coke, furnace slag, and concrete waste for reuse.

Impact Crusher Customized Process Flow

① Primary Crushing and Feeding: Material undergoes primary crushing in a jaw crusher, then is uniformly fed into the impact crusher via a feeder

② Impact Crushing (Medium-Fine): A heavy-duty rotor rotates at high speed; hammer plates forcefully strike the material against the impact frame, repeatedly impacting it until the target particle size is achieved; hydraulic online gap adjustment controls the final product’s particle shape

③ Screening and Grading: Vibrating screens sort the material; qualified products are sent to storage, while oversized material is returned to the impact crusher in a closed-circuit cycle

④ Dust Collection: Baghouse dust collectors provide full-process dust control; fine powder by-products are collected and reused

⑤ Automatic Lubrication: An automatic lubrication system supplies oil at set intervals and quantities, ensuring bearings remain in optimal lubrication condition

The high-speed impact crushing principle subjects the material to repeated impacts between the rotor and the impact frame, resulting in a rounded final product shape with low content of needle- and flake-shaped particles. Hydraulic gap adjustment enables rapid maintenance without disassembly, while wear-resistant alloy reinforcement components extend replacement intervals. When integrated with upstream and downstream equipment, it forms a complete closed-circuit crushing and screening system.

Services

Solution Design: Based on material type, hardness, feed size, target output, and finished product specifications, we recommend specific PF series models (PF0807 to PF1315) and complete line solutions.

Equipment Manufacturing: Heavy-duty rotors undergo precision machining and dynamic balancing; wear-resistant alloy welding wire reinforces vulnerable components; no-load test runs are conducted prior to shipment.

Installation and Commissioning: Engineers provide on-site guidance for installation and integrated testing, including training on hydraulic chamber opening operations, impact frame clearance adjustment, hammer plate replacement, and automatic lubrication system setup.

Operation and Maintenance Management: One-year warranty + lifetime technical support, including wear part replacement schedules, spare parts lists, and remote diagnostics.

Impact Crusher Overseas Case Studies

Vietnam — Hanoi Limestone Aggregate Production Line

Commissioning Date: 2023 | Equipment Model: PF1315 Impact Crusher | Material: Limestone (Compressive Strength approx. 80 MPa)

Project Background: The client is an aggregate supplier serving infrastructure projects in northern Vietnam. Previously, they operated two outdated impact crushers in parallel, facing issues such as high energy consumption, frequent liner replacement, and inconsistent product particle shape. With the simultaneous commencement of highway and urban complex projects in Hanoi and the surrounding areas, the client urgently needed to increase production capacity from 300 t/h to over 500 t/h while controlling operational costs and minimizing downtime.

Production Capacity Data: The entire line has a designed capacity of 550 t/h. It reached stable production three months after commissioning, with a peak capacity of 580 t/h and a feed size of ≤300 mm. The system forms a closed-circuit production loop with a front-end jaw crusher for primary crushing and a rear-end vibrating screen. The finished products are classified into four specifications: 0–5 mm, 5–10 mm, 10–20 mm, and 20–31.5 mm, with an overall screening yield of approximately 92%.

Customer Feedback: "We selected the PF1315 from among three options, and the results since commissioning have exceeded expectations. The lock-in design for the impact plates has cut replacement time by more than half. The aggregate has a rounded shape, with flakiness and elongation controlled below 6%. The concrete mixing plant has reported excellent workability, and we have raised our selling price. The automatic lubrication system eliminates the need for daily manual greasing, and to date, there have been zero bearing failures due to oil shortages. In nearly two years of operation, there have been no unplanned shutdowns; the maintenance team has been reduced from four to two people, the equipment’s overall utilization rate remains above 95%, and the payback period was three months shorter than expected."

Impact Crusher Frequently Asked Questions (FAQ)

Q1: What materials can the PF impact crusher, used for reducing the volume of medium and fine-sized materials in building materials and ores, process? What is the capacity range?

The PF series impact crushers, designed for reducing the volume of medium and fine materials in building materials and ores, are specifically engineered for medium-hard materials with a compressive strength of ≤100 MPa. They cover materials such as limestone, clinker, slag, coke, and concrete, with a capacity of 250–750 t/h and a maximum feed size of ≤300 mm. The PF1315 unit in Vietnam achieved a measured output of 550 t/h with excellent particle shape, receiving high praise. Simply provide the material type and required capacity, and we will match the appropriate model.

Q2: Is maintenance and servicing of the hydraulic-opening impact crusher convenient? How much labor is saved with automated lubrication?

The hydraulic-opening impact crusher features a hydraulic shell-opening mechanism that eliminates the need for disassembly during major overhauls, and the impact frame clearance can be adjusted online. Automated lubrication provides timed and metered oil supply, eliminating the need for manual greasing; a cement plant in the Philippines has reported zero bearing lubrication failures since commissioning. Daily maintenance primarily involves routine inspections and hammer plate checks, and training includes a full operational demonstration.
