PF Impact Crusher

Feed Size:: 10-500mm

Capacity:: 10-800T/H

Applicable Materials:: limestone, coal gangue, dolomite, shale soil, magu stone, construction waste, etc.

Application Range:: Widely used in ore crushing, railways, motorways and construction industries

Medium-hardness and below brittle materials represent the most advantageous application domain for impact crushers, which excel particularly in the efficient processing of materials such as limestone, concrete blocks, and asphalt. Through impact crushing, they produce recycled aggregates with excellent particle shape.

Description

Product Overview

The impact crusher produces finished particles with a cubic shape, free from tension and cracks, resulting in superior particle form. It can crush various coarse, medium, and fine materials with a feed size not exceeding 500mm and compressive strength not exceeding 350MPa. Impact crushers find extensive application across diverse sectors including mineral processing, railways, motorways, energy, cement, chemical industries, and construction. Their discharge particle size is adjustable, enabling versatile crushing specifications.

Working Principle

The impact crusher is a type of crushing machinery that utilises impact energy to break down materials. During operation, driven by an electric motor, the rotor spins at high speed. When material enters the impact plate zone, it collides with the impact plates on the rotor, breaking into smaller pieces. It is then propelled towards the impact device for further crushing, before rebounding off the impact liner back into the impact plate zone for renewed crushing. This process repeats, The material progresses through the first, second, and third impact chambers in a series of crushing stages, reducing in size until it reaches the required particle size before being discharged through the outlet.

Core Components of PF Impact Crusher

1. Rotor Assembly:
The heart of the equipment, comprising the main shaft, rotor disc, and impact plates. Featuring heavy-duty construction and precise dynamic balancing, it ensures smooth operation at high rotational speeds while delivering substantial impact energy.

2. Impact Plate System:
Includes two or three tiers of impact frames with mounted impact liners. Together with the rotor, they form the crushing chamber—the critical component where material undergoes impact collision. The impact frame’s position can be adjusted via a mechanism to control output particle size.

3. Transmission System:
Directly drives the rotor at high speed via a V-belt connected to the electric motor, ensuring high transmission efficiency.

4. Frame: Welded Heavy-Duty Frame:
Features a robust structure. The rear frame can be hydraulically opened, providing exceptional convenience for inspection and maintenance.

Features

The finished product exhibits excellent particle shape and high value

Employing the principle of impact crushing, materials fracture along their natural cleavage planes, yielding predominantly cubic-shaped products with minimal needle and flake content. This particle shape is particularly suited to applications demanding stringent grain specifications, such as high-grade road surfacing materials and commercial concrete aggregates, significantly enhancing product pricing and market competitiveness.

Simple operation and maintenance, flexible adjustment

The gap between the impact plate and the hammer plate can be easily adjusted via hydraulic or manual mechanisms, enabling precise control of the discharge particle size to meet diverse customer requirements. The rear frame features hydraulic opening, making the replacement of wear parts—such as hammer plates and impact plates—exceptionally straightforward and swift, thereby significantly reducing downtime.

Sturdy construction, excellent value for money

The core rotor features a heavy-duty design with substantial rotational inertia, ensuring smoother operation and enhanced crushing force. Critical wear-resistant components (impact plates and counter plates) utilise novel high-chromium alloys or composite ceramic materials, delivering superior abrasion resistance and impact resilience. This results in extended service life and reduced overall operating costs.

Features a reshaping function, serving multiple purposes in one device

Not merely a crusher, but also a highly efficient aggregate shaping machine. It can be employed to refine poorly shaped aggregates from equipment such as cone crushers, thereby enhancing the overall quality of finished materials in the production line and achieving ‘multiple functions in one machine’.
